I think you should think about different ways to solve theselective >about
problem. Do
you need to solve them all 30000 times? Can you be
which ones you run?
What does solve mean? Compute a filter on a piece of data?
Yes, I need to compute a filter on a piece of data, and it's
unavoidable that I need to do this 30000 times. Each set of
filter coefficients has to be calculated independently.
I'm going to run the matlab profiler on my code to find
bottlenecks, but I still believe the code will take quite an
amount of time to run.
I've never heard of the term "embarrassingly parallel." ;-)
I'll have a look at both Star-P or Matlab DCT to see if they
can help the situation.
Even if you will not consider buying some software that
facilitates parallel computing, you will still be better of
buying multi-core machines. They provide better bang for >the
buck: in terms of price per unit of processing power and in
terms of energy consumption. After all, you could just run
multiple Matlab sessions on a multi-core/multi-processor
machine.
I'm not sure if running multiple instances of Matlab on a
dual core system is more efficient. I've tried this, and two
simulations running in parallel on seperate instances of
matlab is often slower than two simulations in series on the
same machine.
Thanks for the help so far!
