Are the tests simultaneously using lots of CPU on all three processes, or (more likely) is one doing the work and the other two waiting around for most of the time. In this case, no need to divide by two or three. > I'd like to restrict @parallel(ncpus=...), where "..." is something > like 1/2 (or 1/3?) of the available CPUs.

Do you see a way? I don't know of any way to do that, but saving to a file isn't so bad. - Robert -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
