For each simulation you run, make sure you run it only on nodes that are not already being used by other people to avoid interfering with ongoing simulations.
The following steps allows you to see who's using which nodes. It lists the users of the top three cpu-consuming process. If the user is not root or yourself, then somebody else is using the node!
- Copy the following to a file called cpu_load.sh in your home directory:
#!/bin/bash
# file: cpu_load.sh
ps --sort=-pcpu -eo pcpu,user | head -4 | tail -3
- To check the load on crunchers and who's using which node, run:
for i in `seq 144 160`; do echo figipc$i; ssh figipc$i '~/cpu_load.sh'; done | less
