slow training on single gpu
显示 更早的评论
hey, i'm trying to train inception v3 on single gpu. it takes about 21 hours for 20,000 iteration. it takes more than an hour for 1000 iteration of 32 images in a minibatch. caffe and tensorflow are 10 times faster on the same computer. in caffe it takes 7 minutes for 1000 iterations. how can i improve the training on matlab? Thanks

... install a faster GPU, perhaps with more memory?
There can be big performance differences between different GPUs, especially if double precision is being used. A higher GPU clock rate does not necessarily mean that it will be the best for double precision: some GPUs have special double precision units that speed processing up a lot.

Upgrade MATLAB with each new release, we are making big performance improvements all the time.

Only certain matalb versions can be used with particular CUDA toolkits though

MATLAB has its own copies of the CUDA libraries, so the toolkit you install is irrelevant unless you are compiling your own CUDA code.

I think maybe the point is that newer CUDA toolkits do not support some of the older architectures, and newer MATLAB versions do not support older CUDA toolkits.

The only dependency is the driver and the MATLAB version, since MATLAB carries the toolkit with it and it makes no difference what toolkit you install. Maybe that's what you're saying.
