Some observations from building sage-4.8 on a very fast system (32 cores, 512G RAM) using "make -j64 -l32".
First of all, apply the patch from #12329 to prune many unneeded dependencies of the Sage library (needs_review by the way...): Total time for "make build" was 27 minutes, total time for "make doc" 14 minutes, for a grand total of 41 minutes. The critical path to build all of Sage is as follows (every package depends on the one just above it): (base) patch iconv libgpg_error libgcrypt opencdk gnutls python fortran lapack atlas r + rpy2 The 10 slowest packages to build (slowest first): r atlas scipy polybori maxima ntl singular ecl sage libm4ri -- 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
