I don't know Nimrod other than a quick scan through documentation. I wonder how feasible it is to use C intrinsics or pragmas in Nemerle? Is there a way to propagate OpenMP pragmas or SIMD intrinsics to Nimrod generated C code?

I assume s/Nemerle/Nimrod/ :P

You should be able to accomplish these things by manually emitting C code using the emit pragma, maybe. OpenMP can already be used via the `||` iterator.

Right, that other name was stuck in my head for some reason.

Do you have any concrete plans to provide SIMD vector types and operations in Nimrod?

Yes it's in the works and apart from that importc should be enough, no need for the ugly emit.

Sorry for necroposting such an old topic, but I was wondering about this myself recently. Do any of the Nim libraries take advantage of OpenMP or things like AVX instructions? Or is there anyway easy way to write code that takes advantages of these things?

I've been using them in my project for a while now. I have a simple wrapper for OpenMP here and some SIMD wrappers here.

The SIMD stuff is still a bit of a mess now, but may eventually make it into a separate package.
