Hi everyone,
When I was trying to creating some 8-core multiprogrammed workloads in the
FS mode, I found certain applications get killed by "oom-killer" in some
workload combinations (please see the following error messages from
system.terminal) while other workloads are just running ok. I am wondering
if you have any suggestions for solving this kind of problems.
Thanks,
Dongyuan
