Title: Turning off threading in multinode cluster
Post by: ph on April 1, 2014, 15:22

Dear Sir,
To speedup the calculation using ATK in a multi node cluster environment is it necessary to turn off threading?. If it is so, is it  to turn off every node in a cluster or turning off only in master node?. waiting for your kind advice.

Each node, but normally your environment is inherited by each MPI process so it's enough to set it on the submitting node. Still, to be safe, it's best to set it in your login script (.bashrc) or queue submit script.
