[Bioc-devel] Multiple processor for one expression?

Hi Chen,

Hi All,

Package "multicore" does a good job in enabling multiple processors for
multiple expressions. I am wondering if it is possible to use multiple
processors for one expression, so that I can make successive steps faster
(e.g. A -> B -> C, the later process depends on the result of the former
process). Any hint? Thanks in advance.

There are often ways to exploit parallelization to make things go
faster. Some tasks are easier than others, and sometimes these things
are completely non-obvious, or even attainable only outside the scope
of R or only to those with extreme expertise in obscure things (ie.
using (or writing!) a multithreaded blas library, for example).

Without knowing the details of A, B, and C, you have no hope of
getting a useful answer -- or even a hint for a useful answer, but
I'll answer your question all the same: "Yes, it is possible".

You'll have to provide more details in order to get any useful help.

Note that there is also a "high performance computing" with R mailing
list that might also be helpful.
