openMP and Kerrighed 3.0.0

[m***@public.gmane.org]

Hello, dear enthusiasts! Thanks a lot for your work.

Suggest I have 2 nodes with 8 cores on each node.
According to FAQ http://www.kerrighed.org/wiki/index.php/FAQ
"Kerrighed does not support thread migration. This feature was disabled early
in the port from Linux 2.4.x to Linux 2.6.11. It should come back in the
future."

Does this phrase mean that there is no profit in runnung openMP programs on
Kerrighed cluster with OMP_NUM_THREADS variable more than 8?

Thanks in advance.
