Does thundersvm support multi-GPU training?will multi-GPU make the training faster?

zeyiwen commented 6 years ago

No, it doesn't support multi-GPUs. I think multi-GPUs can help improve efficiency, especially when performing cross-validation or multi-class SVMs.

It will be an interesting problem to extend ThunderSVM to multiple GPUs. are you interested in working into this?

Hello，zeyiwen. I have a question that if 0-th GPU has no memory left. Will thundersvm switch to another one automatically？

Hi @ZesenChen It doesn't support this functionality, but you can specify the GPU id using -u option (cf. parameter).
