Jack Dongarra wins Turing Award

Ah, I personally preferred gotoblas to linpack as it was faster (keep in mind this was a few years ago when I did research, no idea how it kept up). I also enjoyed the story of how an unknown Japanese student ( Mr Goto - cool name ) outdid all the top linear algebra implementations by hand writing everything in assembly. It was an amazing story. This was when everyone said assembly was dead.

I'd guess that previous machine-specific BLAS used assembly. The fundamental feature of the GotoBLAS approach is the blocking structure; that can provide >80% of the performance of hand-tuned assembly/intrinsics-based kernels with plain C in BLIS with vectorizing compilers. Not to minimize Goto's work, but I wonder if van de Geijn, who I think was Goto's supervisor, deserves more credit than he gets.

even at Dongarra's lab, gotoblas saw heavy use. LINPACK didn't need to be the fastest - just the original/reference implementation.
