[Octave-bug-tracker] [bug #49532] parallel package: segmentation fault on matrix multiplication on macOS

[Olaf Till]

Follow-up Comment #2, bug #49532 (project octave):

As yet there was no reply to Mikes request for additional information.
Especially the information regarding BLAS would be important for verification
that this is the right track of thinking.

This would be not the first issue with threads in combination with 'fork' in
parcellfun. I think here we are at the limit of what can be done with just
'fork'ing.

A solution would be a different way, similar to what is done in netcellfun,
but with local servers, spawned with something like fork/ecexve.

I'm now planning to implement such an alternative solution, but it will be in
a different function than parcellfun, maybe within netcellfun.

This alternative way could even make a Windows (non-cygwin) version
theoretically possible, using CreateProcess, though I currently can't assess
the possibilities for process communication there.
