I am running NAMD network version compiled with ibverbs for infiniband, with
Lysozyme input for 250000 steps. It gives highly inconsistent WallClock
times across multiple runs (for example one run took 2500 seconds, another
run with the same input took 6600 seconds). However, when i ran NAMD mpi
version with Hp-mpi for the same input, it is giving consistent WallClock
timings across multiple runs. Also, the days/ns reported by both versions
remain stable across multiple runs.
Does anybody have any idea as to why this might be happening ?
