Hi, According to our installation guide:
*One useful setting for this variable when building Sage is MAKE='make -jNUM' to tell the make program to run NUM jobs in parallel when building. Note that some Sage packages may not support this variable.* and our main build scripts are sprinkled with $(MAKE) instead of invoking "make" directly. But as I understand the jobserver (https://www.gnu.org/software/make/manual/html_node/Job-Slots.html), only the top-level make command should get "-jNUM" flag and sub make commands should not get "-jNUM flag, for the jobserver to work across all make commands. Hence we should revise the paragraph in the installation guide to not recommend to define *MAKE='make -jNUM', but to build sage by make -jNUM at the top-level.* *Am I right?* Moreover I think SAGE_NUM_THREADS environment variable should be used if a sage package wants to run parallel jobs, instead of relying on *MAKE='make -jNUM'.* *Do you agree?* I am considering this issue since currently doc build does not do parallel jobs, and the above issue seems related. Thank you for attention in advance. Kwankyu -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
