this one I don't know if it runs windows or not. but it is an HPC server with
up to 40 cores and 80 threads, 1400W redundant PSU, up to 512GB RAM (so you can
have up to 6.4GB/thread).
if you are doing a lot of parallel builds, this might be a solution. or maybe
you just want to stick to sequential builds instead of doing them in parallel?
note that doing this in parallel, it would peg the disk hard, and there is
probably a performance limit on the amount of things you could do in parallel
before hitting that barrier based on your OS and filesystem chosen.
perhaps the introduction of a compiler that compiles multithreadedly would be
an idea? I don't know how that would work, or how you would divvy up the work.
I don't know whether to
what I was thinking, was that at least, the individual builds could be
parallel-compiled: if you have a master makefile or script which batches these
things off, simply run them as background jobs by appending a & to the command.
the trick is synchronizing. you have to find some way of waiting for the jobs
to become *done* before you go on to the next batch. I will leave this to you.
one way to do this is by leaving a sentinel file named something like
build-x.done
in your main thread/master script, you would have to wait in a loop for this
file to exist, and then delete it. if you have a group of processes, then you
have to check for the existence of the group of files before exiting the loop
like a great big AND.
this might get you thinking in parallel.
these are really basic ideas, but they should work. if you need to kill the
jobs, it would be a task in itself, I would suggest you write a batch file
which greps ps for the different compiler batch processes (make, the name of
any master batch file, etc., and then
leaving the .done flies is not an issue. deleting them would be if the
processes are hanging around and any dependent processes are running.
at a smaller scale, the file compiles could be parallel-compiled. there are
usually plenty of those.
