[Numpy-discussion] MKL + CPU, GPU + cuBLAS comparison

2013-11-26 Thread Dinesh Vadhia
Probably a loaded question but is there a significant performance difference between using MKL (or OpenBLAS) on multi-core cpu's and cuBLAS on gpu's. Does anyone have recent experience or link to an independent benchmark? ___ NumPy-Discussion mailing

Jerome, Thanks for the swift response and tests. Crikey, that is a significant difference at first glance. Would it be possible to compare a BLAS computation eg. matrix-vector or matrix-matrix calculation? Thx!___ NumPy-Discussion mailing list
