Hello. This is Sungho Lee.
I’m using a small cluster (total 160 cores <- 1 master, 15 nodes) for testing ASPECT now.
In the master node or a single node of the cluster, increasing processor makes running wall time shorten using ASPECT 2.1.
However, sharing the problem with other nodes dese not show running wall time shorten rather increases running wall time.
Is this normal because of problem dependent or something wrong?
Even though I’ve tested different network fabric like tmi, ofi and etc, it doesn’t help.
One thing I suspect is my executables and libraries (ASPECT and deal.II) compiled based on intel’s MKL and Intel compilers.
Is this can be a cause for my problem or not?
Any comments can be helpful for me
