Hi Alex,
You can lunch multiple jobs through flair using your own submitting script for PBS queue.
First of all: On the flair tab you can find the config button that open the respective dialog.
Then on the left list you go to Run.
By right clicking on an empty space bellow the Queue (on the right) you can add your own queue, running your own script. Just type a queue name (e.g. normal01) and then on the execution command point to your submission script.
Press ok and you are done.
Now you can submit multiple jobs using your script with the following way:
If you search the flair manual (f1) for 'spawn' you will get some relevant instructions and pictures as well.
Basically, at the "Run" tab, by clicking on the 'spawn' column on the side of the job, you enter the number of desired number of clone jobs. Each will have its own random seed.
Then you can select your customised queue (e.g. normal01) on the top bar with the blue runing man icon where is should say (*Default).
In this way, you can lunch the jobs directly from flair to the cluster.
If you wish to control your jobs however, you will have to use the command of your own batch system.
"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?"
Yes you can launch 24 jobs.
Yes they are more or less equivalent when you properly sum up all the results.
Kind regards
Lefteris

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
