I have:
1) Set NUM_THREADS=100 in 'makefile'
2) Exported NUM_THREADS=100 as an environment variable.
Neither seem to work, but instead I see:
Doctesting 2518 files doing 8 jobs in parallel
Are you doctesting using the command
$ make [ptestlong | ptest]
Yes.
or
$ ./sage -tp<n-thread> [-long] /path/to/sage/devel/
No, I've not tried that.
I recall a discussion some time ago when I said I believed that the default
number of jobs should not be more than 8 even on machines with more
cores/threads, since these are generally multi-user machines and taking over
the things is not a great idea. So some code was implemented to limit the
jobs to 8. But unless I'm mistaken, this is not working.
I think when you do
$ make [ptestlong | ptest]
it defaults to the minimum of 8 threads and the number of cores on
your system. So on any machine that can support 8 threads, then 8
threads are used when you doctest with the latter command.
Yes, *defaults* but how do I override the default? I thought setting NUM_THREADS
in makefile would do, but it does not.
