| 2012-02-27 14:30:13 +0200 | asked a question | Modifying ncpus.py to detect processors on computational nodes Recently we've been attempting to run Sage on a LittleFe cluster (littlefe.net if you're interested to read more), however, the ncpus function reads directly from system settings, thus it only reads the two slots on the head node of the cluster. In order to run other jobs outside of Sage using OpenMPI, we are able to input a machine file generated by a BCCD specific command as an argument for OpenMPI to detect and use the slots on the other nodes. I'm wondering if there is a way to either modify the existing check or if there is another way to detect the slots on the other nodes to fully utilize Sage's parallel capabilities. |
