Hi, I'm Pravin Kumar 👋

HPC Engineer building infrastructure for large-scale GPU compute clusters.

I work on the systems that run AI/ML training and inference at scale — cluster health monitoring, SLURM automation, GPU observability, Teleport SSH fleet management, and GCP infrastructure.

What I build

Project What it does
hpc-cluster-portal Flask dashboard for multi-cluster SLURM + BCM health monitoring with Teleport SSH
gpu-fleet-monitor GCP GPU instance dashboard with Cloud Logging (XID errors, host faults) per node
slurm-node-watcher Policy-based SLURM node auto-drain daemon + standalone nvidia-smi GPU health check
teleport-fleet-ssh Generate Teleport SSH ProxyCommand configs for 10k+ node fleets from YAML
gpu-toolkit nvidia-smi diagnostics, Xid error watcher, GPU process mapping scripts
hpc-toolkit NUMA tuning, huge pages, InfiniBand checks, CPU governors, HPC sysctl configs
Linux Linux sysadmin scripts, bash aliases, Ansible playbooks

Stack

Infrastructure:  SLURM · BCM (Bright Cluster Manager) · Teleport · GCP · OCI
Languages:       Python · Bash · Terraform · YAML
Observability:   Grafana · Loki · Prometheus · Cloud Logging
GPU:             NVIDIA H100 · B200 · GB200 · nvidia-smi · XID diagnostics
Networking:      InfiniBand · RoCE · GPUDirect RDMA

Currently

  • Managing GPU clusters (H100 / B200 / GB200 scale) at NVIDIA
  • Building internal HPC observability tooling
  • Exploring PhD research in AI/ML systems

Open to connecting on HPC, GPU infrastructure, and large-scale ML systems.
