atlas does take several hours to build, even on fast hardware.

Resolution: worksforme
Status: newclosed

Atlas does a lot of runtime optimizations by trying out oodles of possible combinations of different parameters tied to inner hardware (e.g: cache size, cache line size, vector unit size, prefetch policy, and so on). Since it takes measures, it cannot compile multithreaded because each thread would more or less interfere with its neighbor. Therefore, it has its own internal handling of threading during compilation. Just be patient, it should be rewarding at the end.
