Intel Colfax Cluster - Notes - Index Page
Say we would like to submit the command lscpu to run on a HPC cluster node, we can do it like this:
[u4443@c001 lec-01]$ echo lscpu | qsub
21084.c001
Job ID 20184 is now submitted to run on the cluster. Do a cat STDIN.o21084 (in the directory where we run the command) to see output:
[u4443@c001 lec-01]$ cat STDIN.o21084

To see error, simply do cat STDIN.e21084.
To run a user specific binary (e.g. a compiled C++ code hello), process is similar. Just make sure we specify the full path to the binary:
[u4443@c001]$ echo /path/to/binary/hello | qsub
