Can't run nofib in parallel
I was under the impression that make -j$n
within nofib
would run benchmarks in parallel, but it doesn't. The following warning is indicative:
make[1]: warning: -jN forced in submake: disabling jobserver mode.
Whenever make
is called recursively, any -j
flags will lead to this warning and consequently disable parallelisation (which would lead to a number of jobs exponential in the depth of recursive calls).
Parallel benchmarks are useful to get deterministic metrics such as allocations or counted instructions really fast.
