Dear List,
Can I tell spatch to run multiple parallel processes when run with
'-dir', like -j on make? Actually it is starting only one process.
This previous discussion should give you all the information you need:
http://comments.gmane.org/gmane.comp.version-control.coccinelle/680
Basically, you tell each instance of spatch to look at a different portion
of the files, which can be either the first 1/n the second 1/n etc or can
be done in a round robin fashion, and then you just run all the different
instances of spatch in parallel. At the end, it is useful to collect the
standard errors in one file and the standard outputs in another. I made a
program for doing this, which you can find in tools/distributed, but the
mail discussion also proposes a script, which is probably just as good.
