Uses for shared memory machines?

Post by marsh.. » Mon, 02 Apr 1990 18:54:00


   I am taking a graduate class in computer architecture
and we are required to write a term paper. The topic is on comparing
shared-memory multiprocessors with local-memory multiprocessors.

   So far, I have loads of ideas for things to do with local-
memory multiprocessors, but am stumped on the shared-memory
machines. Does anyone out there have ideas for applications
that could get a benifit of running on a shared-memory

   Thanks in advance,

1. Modelling contention on shared-memory machines


Does anybody have any references on the effect of speculative
execution/instruction reordering/branch prediction on memory traces...

I'm trying to model memory contention in what is effectively a shared
memory machine, but have no idea how much detail I need to model in the
main CPU in order to maintain some semblance of accuracy.  Ideally, I'd
model as little as possible (the simulator is plenty slow enough
already, and the less extra coding the better :) ), but there is
obviously no point doing the simulations if the results are too inaccurate.

Thanks :)
