We are using MKL in NumPy. We noticed that performance of cblas_ddot (running on single thread) **significantly** depends on values of incx and incy.
2. MKL uses FMA, but the reproducer uses MUL + ADD. Or using fused instruction (load + FP instructions). 3. Unroll type 4. Frequency We will get back to you soon with an update regarding the progress. Best Regards, Shanmukh.SS Translate 0 Kudos Copy link Reply Sha...
