1 | Hi everyone, |
2 | |
3 | We have several packages (~35) with local USE=cuda. Should we make that |
4 | a global USE flag? It's a quite generic flag for GPU support, so I was |
5 | surprised to learn it was still local when I added support for it to a |
6 | package recently. |
7 | |
8 | Another thing we might want to discuss is a global setting for the CUDA |
9 | architecture to be used¹. We compile from source, so it would be a shame |
10 | not to compile with the right features for newer GPUs². Maybe just |
11 | advertising the NVCCFLAGS one should put in make.conf is enough? |
12 | |
13 | Cheers, |
14 | —Guilherme |
