Hi.
I don't know if there's an easy solution to this, but when I
run `make check', CPU1 runs at or near 100% for about 6
minutes while the other 3 cores sit idly by (for the most
part). The same thing happens with `make test-baseline',
and perhaps `make test-redo' (I wasn't looking last time I
used it). For a comparison, running `make' distributes the
work much more evenly among the cores (see the attached
images).
Is there a way to improve this? I don't want to put too
much extra stress on CPU1 if I run `make check' alot. Or am
I being paranoid?
Thanks
- Mark
