The classic STREAM benchmark, extended to measure NUMA effects.
Enviroment: OS: Ubuntu 7.5.0-3ubuntu1~18.04 gcc: 7.5.0 Packages: libnuma & libpthread are present Logs: ``` /tmp/ccvrxJvo.o: In function `readProc': stream-pthreads.c:(.text+0x7): undefined reference to `numa_run_on_node' /tmp/ccvrxJvo.o: In function `copyProc': stream-pthreads.c:(.text+0x77): undefined reference...
In my opinion, the computation of available NUMA nodes is not correct. Here you find a fix. What do you think about it ?
Dear NUMA-STREAM developers! If I understand it correctly, the latest stream.c @ e5aa9ca should be NUMA aware. The OPENMP threads are spread across the CPUs but all these threads seem...
Right now, we just use the (node+1)%num_nodes. On AMD, that's not sufficient, as nodes have to be on different packages to be sufficiently malicious. The numa_ctl --hardware flag gets that...
