Re: REMD with IBM SP6 LoadLeveler

Dear Luca

I too have tried to run REMD on the IBM Power6 and have found the same
difficulty, ie that you can only run each replica in serial.
I think the problem is due to the fact poe doesnt seem to allow more
than 1 parallel program to be run in the same loadleveler job.
If anyone knows a way round this I would be glad to hear about it!

best regards
Andrew
