Fluent can't run in parallel when hyper threading turning on.
 
The workstation is dell T5500 wih intel 5560 2*6 cores.
Fluent can run in parallel when turn of hyper threading in bios.
If HT is turned on, Fluent can not run in parallel. The mpi options: defaults, hp, intel, opemmpi are both tried and failed.
What's wrong?
