There's more information about this mode [here](WMPL_Upgrades_2026April.md). + +## Notes +* The instructions below are for a Linux-type operating system. Adapting them for Windows is left as an exercise for the reader. +* For the purposes of this document, we will assume that WMPL is running under an account "ubuntu" on a server called "parent"and that we have a child node "node1". +* Node names to not need to match physical machine names (though you might find it useful for keeping track / auditing). +* Parent and children need not be on the same network, but it must be possible to connect between them using ssh and sftp. + +## Prerequisites +### At least Two Computers +You will need at least two computers with WMPL installed. Installing WMPL is covered [here](https://github.com/wmpg/WesternMeteorPyLib/README.md). + +Both Windows and Linux are supported, or a mixture of both. Child nodes can even be run under WSL2 on Windows. MacOS should also work though we have not tested it. + +#### Parent Node +One computer will be the parent node and will +- load the raw camera data to create candidate groups of observations. +- distribute candidates to any child nodes and to itself. +- solve its own workload of candidates. +- receive any solutions uploaded by child nodes and integrate them into the solution dataset. + +The parent node must have access to the raw camera data. The solved trajectories, logs and operational databases will be saved in folders on the parent node (these areas can be network shares). + +#### Child nodes +Other computers will be child nodes and will +- connect to the parent and download any assigned data +- run the solver on the candidates +- upload any successful solutions to the parent node. + +Child nodes do not need access to the raw data and do not require any long-term storage. All solved trajectories are uploaded back to the parent node and then removed from the child. Transient data on the child are housekept after a few days. + +## 1: Setup Connectivity +### 1a: Create Child Node Public Keys +Login on each child node as the account that will run WMPL *on that node* and create an SSH key, then copy it to the parent: +``` bash +ssh-keygen -t ed25519 -f ~/.ssh/wmpl -N "" +scp ~/.ssh/wmpl.pub ubuntu@parent:/tmp/node1.pub +``` +You will of course have to provide the correct login details for the scp command. + +### 1b: Install an SSH Server on the Parent +The parent node must have an SSH/SFTP server to allow child nodes to collect data and upload results. + +The SSH server is normally preinstalled on Linux though you may need to activate it. On Windows, you can install OpenSSH Server as explained [here](https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui&pivots=windows-11). + +### 1c: Create a "wmpl" Unix Group on the Parent +This group will be used to manage permissions for the child accounts on the parent node. +```bash +sudo groupadd wmpl +``` + +### 1d: Create Child Node Accounts and File Structure on the Parent +On the parent, create accounts and the required file structure for each child node as shown below, changing the value of NODENAME as needed + +```bash +NODENAME=node1 +sudo useradd $NODENAME -G wmpl +sudo mkdir -p /home/$NODENAME/files/candidates/processed +sudo mkdir -p /home/$NODENAME/files/phase1/processed +sudo mkdir -p /home/$NODENAME/files/trajectories +sudo chown $NODENAME:$NODENAME /home/$NODENAME +sudo chown -R $NODENAME:wmpl /home/$NODENAME/files +sudo chmod -R 775 /home/$NODENAME/files +``` +You should end up with a structure like the one below. + +![image](node_structure.png) + +### 1e: Set Child Node ACLs on the Parent +Group permissions may not be sufficient to ensure the parent account can access the child accounts. To make certain you can apply extended ACLs to the folders as follows: +```bash +sudo setfacl -R -m user:ubuntu:rwx ~node1 +``` +replace 'ubuntu' with the account that will run WMPL on the parent. + +### 1f: Enable Sftp Logins for each Child Node on the Parent +On the parent, sudo to each child node account in turn and enable key-based logins following the example below. +Additionally while we're still configuring things we don't want WMPL to start trying to distribute data. So we create a 'stop' file in each child's 'files' folder. + +```bash +sudo su - node1 +mkdir .ssh +chown $(whoami):$(whoami) .ssh +chmod 0700 .ssh +cat /tmp/$(whoami).pub >> .ssh/authorized_keys +chmod 0600 .ssh/authorized_keys + +echo "stop" > ~/files/stop +``` + +Test that this has worked by logging into each child node, then attempting to connect to the parent with ssh: +``` bash +ssh -i ~/.ssh/wmpl node1@parent +``` +Answer 'yes' if asked to accept the server key. If you get 'permission denied' check that you added the right key to the child's authorized_keys file on the parent node. + +## 2) Enable Remote Processing on the Parent +### 2a) Configure Remote Processing on the Parent +Copy `wmpl_remote.cfg.sample` to `wmpl_remote.cfg` in the WMPL working directory on the parent. The working directory is the folder that contains the sqlite databases or legacy `processed_trajectories.json` file. + +Edit this file to ensure that the mode is `parent` and then configure one row for each child node, following the patterns shown in the sample file. See [here](WMPL_Upgrades_2026April.md) for more details on how to configure each node and for recommended capacity values, but in general each child node should be allocated capacity of no more than 200 at a time, to avoid delays in processing. + +## 2b) Start WMPL on the Parent Node +You need to run three instances of the correlator on the parent node, one in mcmode 4 to create candidate groups, one in mcmode 1 to perform local solving of candidates, and one in mcmode 2 to perform full monte-carlo solutions. Example command lines are shown below. + +``` bash +# candidate-finder node. This will continuously scan the DATADIR for potential candidate groups +python -m wmpl.Trajectory.CorrelateRMS $DATADIR --mcmode 4 --logdir $LOGDIR --dbdir $DBDIR --outdir $OUTDIR -a 4 --autofreq 15 --addlogsuffix + +# local solver. This will collect candidates and attempt to solve them +python -m wmpl.Trajectory.CorrelateRMS $DATADIR --mcmode 1 --logdir $LOGDIR --dbdir $DBDIR --outdir $OUTDIR -a --autofreq 30 --addlogsuffix + +# local monte-carlo phase solver. This will collect phase1 solutions and add uncertainties +python -m wmpl.Trajectory.CorrelateRMS $DATADIR --mcmode 2 --logdir $LOGDIR --dbdir $DBDIR --outdir $OUTDIR -a --autofreq 60 --addlogsuffix +``` + +With these options the correlator will read data from DATADIR, write trajectories to OUTDIR, write logs to LOGDIR with a suffix indicating which mode it is running in, and save the operational databases in DBDIR. + +These options also instruct the candidate-finder (mcmode 4) to run at least every 15 minutes collecting any new data from the last four days (as set by `-a 4`), the phase-1 solver to run every 30 minutes, collecting any available data irrespective of date, and the phase-2 solver to run every 60 minutes again collecting any available data. + +The remote config file will be read from DBDIR. The file is re-loaded every time WMPL starts a new run (every 15 minutes in this example) and so you can dynamically add or remove nodes by updating the file. Initially all nodes will be disabled because earlier we created "stop" files at step (1f) above. + +## 3) Enable Remote Processing on Child Nodes +### 2a) Configure Remote Processing on the Parent +Copy `wmpl_remote.cfg.sample` to `wmpl_remote.cfg` in the WMPL working directory on the child. The working directory is the folder that contains the sqlite databases or legacy `processed_trajectories.json` file. + +Edit this file to set mode to `child` and to configure the SFTP login details appropriately. + +## 3b) Start WMPL on the Child Node +We run only one instance of WMPL on the child node. +```bash +# local solver. This will collect candidates and attempt to solve them then upload the results back to the parent +DATADIR=. +python -m wmpl.Trajectory.CorrelateRMS $DATADIR --mcmode 1 --logdir $LOGDIR --dbdir $DBDIR --outdir $OUTDIR -a --autofreq 15 --addlogsuffix +``` +When it first starts up, the correlator will connect to the parent, remove the stop file and wait for data to be assigned to it. +On its next pass round the parent will see that the stop file has been removed, and will assign some data to the child. +On the child's next pass, it will collect the data, process and upload the results. +The parent will then consolidate it into the main dataset. + +## 3c) Distributing Phase1 to Child Nodes +In the explanation above we've focused on distributing candidates so that we can quickly obtain initial (phase1) solutions. + +It is also possible to distribute phase1 solutions to child nodes which can then perform monte-carlo solutions. We do this by adding a node to the parent's remote config file, indicating that a node is in "mode 2". Then we start up a node as above, but instead of mcmode 1, we run it in mcmode 2. diff --git a/Documentation/WMPL_Upgrades_2026April.md b/Documentation/WMPL_Upgrades_2026April.md new file mode 100644 index 00000000..b25a10ba --- /dev/null +++ b/Documentation/WMPL_Upgrades_2026April.md @@ -0,0 +1,220 @@ +# WMPL Upgrades +by Mark McIntyre, April 2026 + +## Key points + +- Added new operation mode to create candidates. +- Added distributed processing for candidates and phase1 solutions. +- Added checks for duplicate transactions. +- Replaced JSON database with SQLite databases. +- Slight change to command-line parameters. + +### Operation Modes + +The updated solver now has three core operational modes, numbered 4, 1, and 2. In the code these are MCMODE_CANDS, MCMODE_PHASE1 and MCMODE_PHASE2. The previous mode 1 has been split into two stages numbered 4 and 1 as explained below. + +See the end of this document for examples of how each mode can be used + +Here's what each phase does. + +- In mcmode 4, the solver finds and saves candidate groups of observations. + During this phase, unpaired observations are loaded and candidate groups found. Observations are excluded if they're already marked as paired in the observations database, and potential candidate groups are also checked against the candidate database to avoid reanalysing combinations that were already found.

MCMODE_BOTH | Runs modes 1+2, i.e. loads and fully solves candidates. | UKMON currently uses this mode. | +| 5
MCMODE_SIMPLE | Runs modes 4+1, i.e. creates phase 1 solutions from scratch. | GMN currently uses this mode. | +| 7
MCMODE_ALL | Equivalent to 0 or passing no mcmode | Typically used during manual data analysis. | +| Any other value | Treated as a value of 7 | | + +Note that in modes 0, 3, 5 and 7, intermediate files (ie candidates and phase1 files) are not saved to disk. + +### Single-Server Continuous Processing +In single-server continuous processing mode, run three instances of the solver, one in each of modes 4, 1, and 2. + +In testing, we found that a 16-core server could create around 6000 candidates per hour, while also processing 1000 candidates per hour to get phase1 solutions, and processing around 200 phase1 solutions per hour to get full phase2 monte-carlo solutions. + +We therefore suggest running the mode 4 solver with a frequency of 15 minutes (ie with flags `-a` and `--autofreq 15`). Using a short interval ensures rapid identification and update of candidates as new data arrives on the server. + +Meanwhile modes 1 and 2 can be run with a period of around 30 minutes (`--autofreq 30`), and should be restricted to around 200 trajectories at a time, using `--maxtraj 200`. This ensures that data are processed in reasonable batches and written/updated on disk promptly. It also ensures data are available for distributed processing as explained in the next section. + +### Distributed Processing + +The solver supports distribution of both candidates and phase1 solutions. + +To enable distributed processing, we require one parent node and one or more child nodes. + +On the parent, we set up the system as for single-server continuous processing, then create a configuration file '**wmpl_remote.cfg**' in the same folder as the databases. The content of the configuration file is explained below and a sample file is included in the repository. + +On each child, we also create a configuration file (see 'Child Node Configuration' below). Child nodes can run in modes 1 or 2, collecting relevant data from the parent node and uploading the results upon completion. + +SFTP is used to move data between parent and child, and each child must therefore have an SFTP account on the server hosting the parent. + +Data are written into a 'files' folder in the sftp account's home directory, and therefore the account running the parent instances of the solver must be able to read from, write to and create folders this folder. On my test server I achieved this with POSIX ACLs and Unix group membership. + +Additionally, the solver itself sets permissions on files and subfolders, and these should not be altered. + +The required folder structure for one node is shown below. + +![image](node_structure.png) + +**Parent Node Configuration** + +The configuration file for the parent node specifies the child nodes that are available, the capacity of each node, and the mode that its operating in (modes 1 or 2, no other mode is supported). + +The capacity value can be any integer, with zero meaning the node is disabled and a negative value meaning the node has no capacity limit. Some experimentation may be required to determine the optimal capacity, but in testing I found that my 4-core i7 desktop could process 200 candidates in around 30 minutes, and 200 monte-carlo solutions in around three hours. Limits of 500 for mode 1 and 200 for mode 2 therefore seem reasonable. + +Example parent-mode configuration file: + +\[mode\] +mode = parent # 'master' can also be used +\[children\] +node1 = /home/node1, 500, 1 +node2 = /home/node2, 200, 2 +node3 = /home/node3, 0, 1 + +This indicates that: + +- node 1 is running in mode 1 and has capacity of 500. +- node 2 is running in mode 2 and has capacity of 200. +- Node 3 is currently disabled (capacity zero) and will not be assigned data. + +If we bring node 3 online, we can change the capacity from zero to some suitable value, and the parent will begin assigning candidates to it (see 'Dynamically Adding Nodes' below). + +If no nodes are available, or if all nodes are at capacity, any remaining data will be assigned to the parent node. + +The parent will also stop assigning data to a node if a special file named "stop" is present in the files folder of the child's SFTP home directory. The child nodes create this file when shutting down but it can also be created manually if necessary. + +Furthermore, if data has not been picked up by a child within six hours, then it will be reassigned to the parent node. This ensures that data is not left unprocessed if for example a node crashes unexpectedly or is running very slowly. + +**Dynamically Adding Nodes** + +The parent instance of the solver re-reads the remote configuration file on each loop, and so nodes can be added, removed, disabled or enabled on demand, without needing to restart the parent. + +So, for example, one could create a configuration listing several child nodes with capacity set to zero, which would mean they were initially disabled. The Solver would thus assign all candidates to the parent node. However, if volumes rose, an instance of the solver could be started up on a child node and the parent configuration file updated. On the candidate finding process's next loop, the file would be re-loaded and data would be automatically assigned to the child. + +You can also _manually_ move files between child node folders on the server. For instance, if you want to move some load from node1 to node2 you can move some of the candidate files from node1's _candidates_ folder to node2's _candidates_ folder. The UNIX command to move 100 candidates from node 1 to node 2 would be: + +_ls -1 ~node/files/candidates | head -100 | while read i ; do mv \$i ~node2/files/candidates; done_ + +**Processing Uploaded Data** + +Upon each loop round, the parent node will scan each node's home directory for uploaded results. These will be integrated into the trajectories data and the databases updated. After integration, a deduplication routine is run. This handles edge cases where a new version of a trajectory is created by a child node. + +**Child Node Configuration** + +The child must be running in mode 1 or 2 - no other mode is supported at present - and should be run with the `-a --autofreq 15` flags, to ensure that it continues to collect and process data promptly. + +The child configuration file specifies the server, user and key to use for connections to the parent node. Port is optional but can be specified if a non-standard SFTP port is in use. + +\[mode\] +mode = child +
\[sftp\] +host = testserver.somewhere.com +user = node1 +key = ~/.ssh/somekey +port = 22 + +At startup, the child node will connect to the parent and remove the "stop" file, if present. This indicates to the parent that it is "open for business". The child will then download all assigned data and begin processing it. Downloaded files are moved to a subfolder _processed_ on the sftp server. Upon completion it will upload the results to the sftp server, then look for new data to process. + +Note: do not use the `maxtraj` parameter with child nodes. If this parameter is set, then there's a risk that a backlog of downloaded-but-unprocessed data will build up. For example if the child's capacity is set to 200 on the parent node, but the child is limited to 100 via `maxtraj`, then it will download 200 on each pass, but only process and upload 100. + + +**Stopping a Child Node** + +Any node can be terminated by pressing Ctrl-C or by sending SIGINT to its process. The node will stop processing promptly and create a "stop" file on the sftp server. Note that termination will leave data incompletely processed and no upload will take place, and so it is advisable to wait until the child's logfile indicates it is idle. + +**Recovering from a Child Node Crash or Shutdown** + +If a child node crashes or has to be shut down while data is being processed, identify the most recent, potentially incomplete, data set and move it back from the `candidates/processed` or `phase1/processed` folder to the parent's `candidates` or `phase` folder as appropriate. Depending on what stage was reached, the data may be in the child nodes' folders on the server, or in the parent node folder. + +The latest data set assigned to a node can be identified by checking the parent log files. The example below shows a candidate and a phase1 solution assigned to child nodes node1 and node2. +``` bash +$ egrep "node1|node2" *.log | grep saving + +2026/06/05 16:28:07-INFO -CorrelateRMS :1930 - saving 1780646962.313761_US.pickle to /home/node1/files/candidates +2026/06/05 16:15:11-INFO -CorrelateRMS :1930 - saving 20260604_214203.292_HR_trajectory.pickle to /home/node2/files/phase1 +``` + +## Duplicate Transaction Checks + +A check has been introduced in both candidate finding and phase1 solving that examines the database for potential duplicate or mergeable trajectories. + +Duplicates are defined as trajectories that contain the same observations. When detected, the solution with the least ignored observations is retained and the duplicates are deleted from the database and disk. + +Mergeable trajectories are defined as those with at least one common observation. In principle these should never arise but in practice with a distributed processing model, it is possible. For example, a candidate might be found and handed off for solving but while it is still being solved, a new observation might be uploaded by a camera, and so on its next pass the candidate finder creates a second candidate with an additional observation and a different reference timestamp. When detected the better of the two mergeable trajectories is retained. + +Aside: A better solution is to remove both solutions and allow the the candidate finder to identify a single combined candidate on its next pass. This is still being investigated. + +## Databases + +The JSON database has been replaced by three SQLite databases, one for Observations, one for Trajectories and one for Candidates. + +This approach was taken because most trajectory and observation database writing takes place during phase 1 solving, but some takes place during candidate finding notably when reprocessing previous trajectories with new observations. By splitting the databases, we minimise potential concurrent write situations. SQLite does not support multiple simultaneous writes, and though it will back off and retry after a few milliseconds, it is preferrable to avoid unnecessary delays. Additionally, it simplifies the process of merging in data from child nodes and avoids potential deadlocks when doing so. + +**If The Solver Crashes** + +Although most operations are immediately committed to the databases, it is possible for the solver to crash and leave an incomplete transaction. This will be revealed by the existence of write-ahead logs in the database directory e.g. "observations.db-wal". These files should *not* be deleted as upon next startup, SQLite will complete any pending transactions. This minimises the risk of data loss, and at worst may lead to observations being reprocessed. This is preferable to trajectories being missed. + +**The Legacy JSON database** + +The legacy JSON database is no longer used It is not deleted however, after the initial data migration described below it is no longer being used and can be moved to long-term storage if desired. + +**Initial Population of SQLite** + +When the Solver is started up, it checks for the existence of the SQLite databases. If they are not present, it creates them and prepopulates them with the last few days of data from the old JSON database if available. For example, if run with the auto flag and default period of 5 days lookback, the last five days of data will be copied to SQLite. This ensures that sufficient observation and failed trajectory data is present for normal operation of the solver. + +The JSON database is then closed and is not used again in any future pass of the solver. It is not truncated, archived or deleted and remains as an historical record of the state of the database as at the cutover date. + +**Historic Reruns** + +If the solver is rerun for an historic period from before the cutover, there will be no paired observations or failed trajectories data in the databases. The assumption is that if we are rerunning for an historic period, we are either looking to integrate new observations into the dataset or to recalculate trajectories using improved mathematical models. In either case it seems likely we'd want to start by reanalysing the raw data. + +That said, should we wish to copy historical data into the SQLite databases, this can be done with the command-line interface to CorrelateDB as shown below: + +_python -m wmpl.Trajectory.CorrelateDB --dir_path rms_data --action copy --timerange "(20251215-000000,20251222-000000)"_ + +This will copy observations and failed trajectories into SQLite from the JSON database in _rms_data_ for a date range 2025-12-15 to 2025-12-22, creating the SQLite databases if necessary. + +This is quite a slow operation - on my 4-core i7 desktop it takes about several minutes to copy a week's worth of data. + +## Command Line Options + +One option has been removed and two new options added + +Removed: + +- \--**remotehost**: this has been superseded by the remote configuration file + +Added: + +- \--**addlogsuffix**: default false - this adds a suffix to the logfile to indicate which phase is being run. + For example, with this flag passed, the logfile for a run in mode 4 (candidate finding) would be something like \_correlate_rms_20260214_121314_cands.log* whereas a phase-1 log file would be _correlate_rms_20260214_121314_simple.log_. + +- **\--archivemonths:** default 0: this specifies the number of months' data to keep in the databases. Data older than this number of months will be archived. A value of zero means purge rather than delete. At least 21 days data will always be kept, and if a time-range is specified when calling CorrelateRMS, then only data older than this will be archived or purged. + +## Examples of using the Modes + +In the below examples, raw camera data is in `$DATADIR`, and the output and any intermediate files are being written to `$TARGDIR`.
