Dear Bert,
Thanks for your reply...
So> cmpfun(mclapply)
should do the job right?
By the by, how can I give a reprex? Reprex of the code that I am giving to
mclapply (as FUN argument)?
Yours sincerely,
AKSHAY M KULKARNI

Unlikely

Byte code compilation should be automatic in both cases, as I understand it. Of
course, I could be wrong due to special features of parallel programming, etc.
A reprex might be helpful here.
Cheers,
Bert

Dear members,
I am using pbmclapply, the progress bar version of
mclapply, from the parallel package. The point is, pbmclapply is three times
faster than mclapply, and I think the most probable reason would be that
pbmclapply is byte code compiled (I can think of no other reason).
I know the cmpfun function from compiler package. If I do:
> cmpfun(mclapply)
will the job be done? The point is mclapply may look for other functions in the
parallel package. So I have to compile the whole package right? How do you do
that? or in general, how do you byte code compile a whole package?
Thanking you,
Yours sincerely,
AKSHAY M KULKARNI

A reprex is a minimal example that performs as you described. It is up to you to trim your code down to eliminate irrelevant computation while not eliminating the described behavior. You may discover something about your own code in the process that answers your question, or you will be able to demonstrate the issue, or we may still not be able to reproduce if it is related to your system.
