Hi John,
Thanks for the SNUG '02 report - vital reading as ever. I noticed that in
the DC/ACS section, Kent Ng of Microsoft/XBox asked "How does the ACS
parallel job function compare to Makefiles?"
Kent, ACS generates a makefile for you. ACS sorts out your dependancies,
spits out a makefile, and, if you want, can stop there. So, if you need
to, you can edit the makefile to incorporate any other trickery that you
want, then run "make". What's more, it's a Gnu makefile, where you can
control the number of jobs that run in parrallel. That's how we use it
here.
