Are you doctesting using the command $ make [ptestlong | ptest] or $ ./sage -tp <n-thread> [-long] /path/to/sage/devel/ > 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. -- Regards Minh Van Nguyen -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
