I am running large cases on fluent (case file 10GB) in Fluent on parallel on multiple nodes using infiniband. I always fall into this problem where fluent takes large time while building the mesh. This is problem occurs 7/10 times I run a case but in other instances it runs smoothly.
I usually use read/partition/metis to open my case files, have also enabled parallel/fast i/o option (have tried without that too) Have anyone found a workaround for this issue?? Each node that I use had 20 Intel Xeon processors and 128 GB RAM, I usually use 5 of them! Help is much appreciated |
