How to launch a memory thread in memory node? I mean which executable file should I use? benchmark?

[dxlog0]

May I misunderstand " Due to the limited size of our cluster, we emulate each server as one MS and one CS. Each MS owns 64GB DRAM and 2 CPU cores, and each CS owns 1GB DRAM and 22 CPU cores."

So,shoud I just run bencnmark on each node, and these nodes are memory nodes too? emm, then how to limits the CPU cores in MS and the DRAM size in CS?

Yes, when you run benchmark, each process will launch a memory thread to serve memory chunk allocation:

Sherman/src/Directory.cpp

Line 25 in 76e208b

dirTh = new std::thread(&Directory::dirThread, this);

We limit the CPU cores by creating the fixed number of threads, limit the MS memory by setting the conf.dsmSize in DSM class, and limit the CS memory by setting the cache_size in IndexCache class:

Sherman/src/DSM.cpp

Line 34 in 76e208b

baseAddr = (uint64_t)hugePageAlloc(conf.dsmSize * define::GB);

Sherman/include/IndexCache.h

Line 55 in 76e208b

uint64_t memory_size = define::MB * cache_size;
