> I this this issue occurs only if you have a lot of CPU cores, but slow
hard disks. Anyway, the patch at think !http://www.singular.uni-
kl.de:8002/trac/ticket/250 should cure it.
That looks a very trivial change. If I understand correctly, just one line
{{{
$(basefactorysrc:.cc=.o): factory.h
}}}
is added. But it might be better to put it on another ticket, otherwise
this could drag on for ages - the ticket is already 7-months old.
Singular is one of the slowest packages build for me on my Ultra 27,
taking about 8 minutes if I recall correctly. But I'm concerned that
delaying this much longer will cause more problems than a few minutes of
wall time will make.
BTW, I've run with 1000 threads on systems with only 4 cores. It's not
optimal, but does allow a reasonable simulation of larger parallel builds
to be made.
A big problem in my opinion, is that the server disk.math, which serves
all the home directories has been mis-configured to increase the speed of
NFS. So failures on home directories might not be code errors, but simply
mis-configuration of the server.
