The only criteria should be the availability of the CPU and Memory. As along as the CPU and Memory are available we can submit as many jobs as possible.
To know that we have certain tools which should help you to know the CPU and Memory available on your server.
A 286 chip or a Pentium IV class chip? Single core or dual core? Single CPU or multiple CPU? 640KB of memory (which Bill Gates once asserted should be all you ever need) or more? And so on. Your question is moot without specifying a particular hardware configuration.

Any contribution to this forum is my own opinion and does not necessarily reflect any position that IBM may hold.
I talked to our DS Admin and asked the information about the server configuration and as has been mentioned, the answer to my question is dependent on the server info which means I cannot get a generic answer.
