(CCing the list - you don't want to miss the answers from Reuti &
other experienced Grid Engine experts on the list!)
1) You can set "slots" to anything - as long as it is a natural
number. It can be greater than the number of processors in the server.
2) I don't fully understand this "environment server" setup - is it a
process running on the local machine, or a remote process providing
Monte Carlo simulation as a Service (MCSaaS :-D )??
And if it is a local process, then what is the issue of starting it by
Grid Engine, so that resource accounting would work as expected??
