I thought it would be interesting to get these running on Mac OS X/
PPC since there's no Darwin makefile included in the release. I had
to hack the scripts to get it working though and the tests ran, not
without their own problems. Firstly, the changes made to get them
*working* in OS X:
$ diff Makefile.Darwin Makefile.Linux
42,44c42
< atomic \
< getcontext \
< setcontext
---
> atomic
47c45
< include ../Makefile.com.Darwin
---
> include ../Makefile.com
I used the Linux makefile as a basis since it contained the least
amount of compiler flags and gcc is the c compiler most will use on
both systems. Notice the added getcontext and setcontext tests to the
elided benchmarks list.
$ diff Makefile.com Makefile.com.Darwin
112c112
< $(CC) -o tattle $(CFLAGS) -I. ../tattle.c libmicro.a -lrt -lm
---
> $(CC) -o tattle $(CFLAGS) -I. ../tattle.c libmicro.a -
lSystem -lm
It seems like rt isn't available on Darwin (at least not on Mac OS X
10.4.1), so I used System as per the suggestion found here http://
www.eca.cx/ecasound-list/2004/10/0056.html. It compiled fine, but I'd
like suggestions on this.
$ diff Makefile ../libMicro-0.3.0.orig/Makefile
72c72
< @mkdir -p bin-`arch`; cd bin-`arch`; MACH=`arch` $(MAKE) -
f ../Makefile.`uname -s` $@
---
> @mkdir -p bin-`uname -m`; cd bin-`uname -m`; MACH=`uname -m`
$(MAKE) -f ../Makefile.`uname -s` $@
$ diff wrapper ../libMicro-0.3.0.orig/wrapper
37c37
< ARCH=`arch`
---
> ARCH=`uname -m`
$ diff bench ../libMicro-0.3.0.orig/bench
70c70
< ARCH=`arch`
---
> ARCH=`arch -k`
94c94
< printf "!Processor: %30s\n" `arch`
---
> printf "!Processor: %30s\n" `uname -m`
This was a big annoyance. uname -m on OS X/PPC returns "Power
Macintosh", and the scripts couldn't cope with the space (especially
with copy commands in there!). arch seems to be a decent substitute,
but it doesn't take any arguments on OS X so I also had to replace
the arch -k in bench.
So the tests compiled and ran, but as soon as I got to the fork I got
resource temporarily unavailable messages (as in the snippet below).
Now I would've expected this to be because of the low(ish) maxproc
and maxprocperuid limit in OS X, so I bumped them up to
kern.maxproc=2048
kern.maxprocperuid=512
with still no luck. Can someone tell me what this setting is in
Solaris? I should post this on the Darwin mailing lists but I thought
I'd share my experience with you guys first.

I've finally got libMicro (the portable OS microbenchmarks

There's now a rough libMicro page in the perf community
w/ a tarball.
Do remember, of course, that current OpenSolaris bits
are debug, so performance measurements are problematic
except with respect to comparisons against another build
of OpenSolaris.
Have fun -
