Parallel nvcc/g++ call?

[kyunghyuncho]

Is it possible to parallelize the compilation (nvcc)? Something along the line how make -j works.

I think it is a good idea. We discussed about this while discussion about the related issue gh-3277.

Also, I think this one is easier to do then gh-3277.

Is there anyone working on this? Or is there any plan on how to get this working?

Nobody work on this. Note, we don't call nvcc anymore. we always use g++ now. There is high level plan, but we don't have detailed plan. There was discussion that we re-work the cache mechanism to don't request a lock. I'm not sure we will work on this now. But this would be related. If you want to work on this, mostly, we need to be able to have this loop parallelized: https://github.com/Theano/Theano/blob/27705c7c60d270670a967f66a3f94924de8f0269/theano/gof/vm.py#L1074 Note, the make_thunk call will cause the taking of the lock. Maybe/Probably you will need to take the lock before that loop. The lock can be taken many times and we remove it only when we release it as many times it was taken. Note, we work to compile less c code, but having this is also useful.

I would be quite busy for July and maybe August. I'll try to tackle it when I got the time.
