Description

This is for HARDCODE_SALT of course.

@Sayantan2048 this should basically be really trivial and would speed up initial building of all salts' kernels a whole lot on multicore systems (eg. super would do it 32x faster). However, you'd probably need to move some code around.

What do you think?

Research direction

Locate the descrypt-opencl code and the HARDCODE_SALT kernel-compilation path first. Determine how per-salt kernels are currently built, then verify that compiling them with OpenMP on multicore systems preserves behavior and reduces initial build time.
