Kazushige Gotō (後藤和茂, Gotō Kazushige) is a software engineer specializing in high performance, hand-written, machine code.
Goto was a research associate at the Texas Advanced Computing Center at the University of Texas at Austin when he famously hand-optimized assembly routines for supercomputing and PC platforms that outperform the best compiler generated code.
In 2010, Goto joined Microsoft's Technical Computing Group with the title of Senior Researcher.
In July 2012, he joined Intel with the title of Software Engineer.
Goto continues to write hand-optimized machine code, utilizing detailed knowledge of the architecture to which he has access.
