Re: Parallel Make

[Noel Yap]

I agree that a lone -j shouldn't default to infinity for practical reasons.  OTOH, a default of 1 would make the flag meaningless and a default of 2 seems unclean to me.  IMHO, -j shouldn't have a default at all.  Further, for those that like the infinite 
behaviour, I think allowing --jobs=infinity would help curb such an appetite a little.

I read through the man page for GNU make and it looks to me like the 
following two lines should be equivalent.

c1 $ gmake A=B -j 4
c2 $ gmake -j 4 A=B
However, apparently c2 limits itself to 4 parallel jobs while c1 is 
equivalent to -j without arguments and spawns a limitless number of jobs.

Additionally, I would like to request that -j without arguments default 
to something more reasonable than -j infinity.  I have seen novice users 
just throw -j without arguments on to the command line hoping for a 
speedier build only to irritate other people on the build machine when 
every process on the system crawls to a halt.  I think -j without 
arguments should mean -j 1 or -j 2.
