for those curious about running their own matmul benchmarks, I wrote a script a while back that works with both linux and MacOS that should make comparison easy. https://jott.live/code/blas_test.cc I saw ~1.2tflops on

Is Duff’s device still relevant? Compilers can typically do such unroll logic for you these days.

The author, Nadav, has a lot of performance gems out there. Another good one explaining how to implement a fast matrix multiply: https://gist.github.com/nadavrot/5b35d44e8ba3dd718e595e40184...

Even in "private mode" (not enabled by default), if I search "squid game mask" it hits maps.googleapis.com with my entire user agent string. How is this private? Perhaps a bug?

Yea I tested it SIMD (8 ops per instruction) and it's hitting 100gflops, so that'd be 12.5k MIPS, right?

Ah, it's actually 100gflops (not 100Gfmas) because the fmla instruction is fused. I just ran it on CPU, single core (no pinning), just using the aarch64 fmla instruction. Using pure BLAS (multithreaded, with the MM ISA extension), I ge

I’ve seen this style before in Python and noticed that it gets kind of dicey once arguments become optional. Suddenly call sites don’t show all the available options and you have to grok the function implementation to get a sense of how to

thanks for adding this context! One caveat is that the PyTorch strides used in the post are defined by elements rather than byte-wise.

by brrrrrm 5y ago
Great question! einsum is almost exactly broadcast + sum. as_strided lets you do “funky” strides to enable all the various convolutions (sliding windows aren’t easily represented with einsum).

Loop refers to "for loop" (but in a limited context where all control flow and indexing operations are composed strictly of loop variables). The wiki on loop optimization[1] has some good links to literature on the topic. [1] ht
