Dear Alex,

One of the ways to do this is to utilize flair and spawn as many jobs as you wish on your local machine, run all of them with Submitting queue = null. This will generate the input files with consecutive numbers as What(2) in the RNDOMIZe card. You can then copy the input files to your cluster, run, copy the resulting files back to your local machine, and do the data analysis in the same flair file.

Best regards,
George

Subject: [fluka-discuss]: Fluka on OpenPBS - only one core is used
Dear experts,
I'got an access on the cluster grid that uses OpenPBS. The only help I can get is the google, and combined with no any experience it leads to this forum as the last chance.
In a nut, I have a script which successfully launches the job, see the attached file. But only one core is used out of 8 (each node has 8 cores).
1) how should I modify the script to launch 8 jobs at once ? I imagine that process is similar like Flair uses. I'm aware that .inp file should contain RANDOMIZ card with default value.
2) If I want to utilize 3 nodes with 8 cores each, can I launch 24 jobs then? As I understand , 12 runs x 1E8 events are not equivalent to 24 runs x 5E7 events , are they?
Regards
Alex
