It would be nice to have OpenMP support enabled in ngspice. This speeds up the simulations significantly if you have a multi-core CPU.

I am currently managing a package in the AUR with OpenMP enabled. Basically, the only change would be to add '--enable-openmp' to the configure flags. There shouldn't be any additional dependency (at least it is not listed in the manual and I didn't have to install any new package).

Thanks
This task depends upon

Adding that flag creates links to libgomp.so (gcc-libs) and libpthread.so (glibc). Technically gcc-libs is provided through the current dependencies, but by a very convoluted path.

(Altogether ngspice libxaw libxmu/libxpm libxt libsm util-linux filesystem coreutils gmp gcc-libs, and that was the shortest.)

This is a bit too long and fragile for my tastes, so I would add the dep explicitly too.

Do you want the AUR package removed if this feature is brought in?

Thanks for looking into this. As for the AUR package, yes, please remove it if the feature is implemented.
