Hi,
I've been trying to reconfigure my system on my x200 laptop. It's been
a day or two, and I've found that my computer has spent the last 25
hours running fftwf tests. I know my laptop is rather weak (2 cores, 8
GB of memory, an SSD) compared to most desktops today, but still, 25
hours seems pretty long.
Guix is running
make check -j 2
which ultimately calls
perl -w ./check.pl -r -c=30 -v --nthreads=2
/tmp/guix-build-fftwf-3.3.8.drv-0/fftw-3.3.8/tests/bench
which calls
/tmp/guix-build-fftwf-3.3.8.drv-0/fftw-3.3.8/tests/.libs/bench -o nthreads=2
--verbose=1 --verify //obcd34320 [... a lot of arguments ...]
Despite the fact that "-j 2" was provided to make, only 1 CPU is pegged
at 100% utilization. I suppose I'll just wait and see what happens, but
25 hours feels very long. It seems on ci.guix.gnu.org, the build times
are generally less than 1 hour:
https://ci.guix.gnu.org/search?query=fftwf
Is this normal, or should I kill the build and try again? What kind of
system is ci.guix.gnu.org building on (how many cores, how much memory)?
