dual core programming

[ptabor]

Hello all,

I'm running a stochastic simulator for chemical rate equations and I'd like to know how to specifically impelement a dual core solution on my AMD athlon 64 X2 4200+ processors.

When I run the task manager with the simulator running, it is apparent that both cpus are running cycles - but I'd like to rig it up to do this manually.

Will I be dealing with OpenMP or MPI or something else altogether?

any info would be appreciated

Just use more than one thread, and the OS will automatically load-balance the two cores effectively.

You can also assign different threads to run on different processors if you want to ensure they'll be running on different processors.

If you're planning on porting your code to a cluster, you'd probably want to go with a process-oriented library like MPI. Otherwise, either OpenMP or MPI should work okay. OpenMP requires compiler support. What OS are you running?

Some compilers promise to automatically parallelize your code; my (very little) experience has been this doesn't work very well.

Good luck,
Tim
