Choosing Where to Execute

The Sun CRE provides you with considerable flexibility in choosing where you want your program to execute. For example, you can specify

• The partition in which you want to execute your program.

• The number of processes you want to start, and how you want to map them to nodes.

• The characteristics of the node or nodes on which you want to run--for example, the minimum amount of memory required or the maximum acceptable load.

See "Specifying Where a Program Is to Run " for additional information on specifying where a program is to run.

You can specify default execution criteria via the MPRUN_FLAGS environment variable; see "Specifying Default Execution Options". You can also override these criteria via options to the mprun command.
