Determine Size of Main memory

[Amir-HK]

Hi

How can I determine the Main memory size in the mem-config.ini.

for the Cache, I simply define Set, Assoc, and block size which determines the cache size like below

BlockSize = (Required)
Size of a cache block in bytes. The total size of the cache is given
by the product Sets * Assoc * BlockSize.

however, for Main Memory, I just have block size variable like below:

[Module mod-mm]
Type = MainMemory
BlockSize = 256
Latency = 200
HighNetwork = net-l2-mm

So, how can I Determine the Main memory size?
