to check if Channelflow 2.0 runs properly on your cluster, we might want to compare the MPI performances in this forum.
For this purpose, I suggest using the program “benchmark” in the “tools/” directory. Then, please provide similar information as this
@ EPFL cluster Fidis (1 node = 28 CPUs), on 4 nodes = 112 cores
tools/benchmark -nc -np0 8 -np1 14
reading a FlowField file with (Nx,Ny,Nz)=(1024,121,1024) gives
Average time/timeunit: 68.1176s
Looking forward to your numbers
PS: just to make sure, it is very important that such benchmarks are done using a code compiled in “release” mode
