ptrendx commented on issue #7813: Performance doesn't improve (scalability issue) with # GPUs with running train_imagenet.py URL: https://github.com/apache/incubator-mxnet/issues/7813#issuecomment-328649594 As I said, alexnet is a very small network, so with 8 physical cores you probably will not get a much better scaling result with those GPUs. Try a bigger network (vgg, resnet 50 or something similar) where there is not as big stress on IO and you should get a very good scaling result. Still, IO speed is a big problem going forward even for larger networks and that is why we are working on ways to improve it (besides my PR see for example #7092) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
