[SOLVED] Parallel execution of shell processes

Issue

Is there a tool available to execute several process in parallel in a Windows batch file? I have found some interesting tools for Linux (href="http://mi.eng.cam.ac.uk/~er258/code/parallel.html" rel="noreferrer">parallel and PPSS), however, I would need a tool for Windows platforms.

Bonus: It would be great if the tool also allowed to distribute processes in an easy way among several machines, running the processes remotely a la PsExec.

Example: I would like that in the following for loop

for %F in (*.*) do processFile.exe %F

a limited amount of instances of processFile.exe are running in parallel to take advantage of multi-core CPUs.

Solution

GNU xargs under Linux has a "-P n" switch to launch "n" processes in parallel.

Maybe cygwin/mingw build of xargs also supports this?

Then you can use:

xargs -P 4 processFile < fileList

No fancy multi-node process spawning, though.
