Hi,

I am trying to use a 12 core (6 Hyperthreaded) and when running
fluent 2ddp -t12

I am getting the following error/warning

Process affinity not being set. core ids failed check (maxid>cores, ht>1)

Does anybody have any idea what it means? The simulation starts but I am getting this warning.

Thanks

Try with lesser number. And when you say 6 hyperthreaded, it might mean that there are 6 dual core processors.

If you have unix machine, check using cat /proc/cpuinfo in a terminal, what is the last number of processor. If it is 11, then your command is perfectly alright. However, if it shows some other number, say n, then your command can be fluent 2ddp -tn+1

When I started fluent to read file,I got the following error/warning
Note:Rank=0:Process affinity not being set. Offsets failed sanity check.
Note:Rank=1:Process affinity not being set. Offsets failed sanity check.
Note:Rank=2:Process affinity not being set. Offsets failed sanity check.
.......
(My workstationo has 12 core, even I use 2 core ,I'll also receive this message)
How can you solve the problem?
