CPU Level Parallelism #3

Hello!

This library looks great, but I was wondering if it has CPU multi-threading blas capabilities. Reading through the code for some of the *gemm files, it almost appears to be the case.

I'm trying to perform a benchmark on AWS between g2 and c4 instances. I was hoping to find some way of writing a single code base that will perform the same function on the two different instances.

For CPU multi-threading, it depends on what CPU BLAS you link, and how you configure them.

Please don't pay too much attention to CPU, this is a multiGPU BLAS. For more details, you can visit cuBLAS-XT. They are pretty same, but different approach.

Alright, good to know and thanks for the lead.

Btw, are there any plans for supporting double complex based operations in the near future?

linnanwang commented 8 years ago

good catch. I just merged ZGEMM a few seconds ago.

romanlarionov commented 8 years ago

Ohh I didn't know that was a valid pull request. Is the current master golden? I pretty much need to support zgemm and would rather use this over cublas-xt.

linnanwang commented 8 years ago

Yes, the current master has ZGEMM.
