I found the latest version of clBLAS on Fiji achieves a fantastic ~4 Tflops (on 2^n matrices). NVblas has probably had more resources allocated to it that clBLAS. I'd be positively surprised if the kernels in Neantherdal beat those. Do you plan on adding benchmarks for the GPU calls ? I can help running the clBLAS benchmarks, if you like, since I have a tuned setup.
If you want to take a look at it, the AutoGemm generator seems to be a simple python script written in order to overcome the limitations of the C preprocessor. I was considering using its tiling structure, since I already have a Lisp->OpenCL compiler in place (and have had no luck beating it). See, for instance,

- dragandj 10y agoWhat is the theoretical MAX flops on that Fiji card? I achieve 3.75 TFLOPS on Hawaii, which has much less power than Fiji...
- akssri 10y agoI think it's about 5.6 Tflops. Wow, 3.75 Tflops on Hawaii is very good indeed; I agree this is not something that clBLAS would beat by a wide-margin if at all.
- dragandj 10y agoJudging by this page, https://en.wikipedia.org/wiki/List_of_AMD_graphics_processin... https://en.wikipedia.org/wiki/List_of_AMD_graphics_processin..., Fiji has more than 8 TFLOPS.
- akssri 10y agoAh, you're right; 5.6 Gflops is for Hawaii. That's doubly impressive. I'll make sure to try your kernel then. Thank you!
- akssri 10y agoAh, is this https://github.com/CNugteren/CLBlast https://github.com/CNugteren/CLBlast ? I was looking at, https://github.com/uncomplicate/neanderthal/blob/master/src/opencl/uncomplicate/neanderthal/opencl/kernels/amd_gcn/blas.cl https://github.com/uncomplicate/neanderthal/blob/master/src/...
- dragandj 10y agoYep, CLBlast. My old kernels are from the pre-CLBlast era. Now they are deprecated.
- dragandj 10y agoActually, the man who writes those amazing kernels is Cedric Nugteren. I call HIS kernels.
