I think you'll maximise your chances by sending mail about GUM and
Glasgow Parallel Haskell to the GpH mailing list

| Subject: Question about how GUM works
| 
| Hi All,
| 
| I have a question about GUM - the runtime system for Parallel Haskell.
| There are below words in the paper addressing GUM architecture:
| "The first action of GUM program is to create a PVM manager task,
whose
| job is to control startup and termination. The manager spawns the
| required number of logical PEs as PVM tasks, which PVM maps to the
| available processors."
| 
| So my question is how many PEs the PVM mamager task will spawn? The
| number is accordant with the processor number or determined by some
| other things? And will the number of PEs be changed during the
execution
| of the program or not?
| 
| Thanks,
|
