ASPIRE Researchers Recognized for Influential 1997 Autotuning Paper


A paper written by ASPIRE Director Krste Asanovic while a graduate student at Berkeley working with fellow former graduate student Jeff Bilmes (now a Professor in the EE Department at University of Washington) and
former undergraduate Chee-Whye Chin (now an Assistant Professor in the Department of Mathematics at the National University of Singapore) under the supervision of Prof. James Demmel has been selected for
inclusion in the “25 Years of International Conference on Supercomputing” volume. The selection committee considered 100 most cited papers out of approximately 1800 papers published in the ICS proceedings between 1987 and 2011, and the Berkeley paper entitled “Optimizing matrix multiply using PHiPAC: a portable, high-performance, ANSI C coding methodology” was one of 35 selected for inclusion in the volume.

Final RISC-V User-Level ISA Standard Released

Krste Asanovic

RISC-V is an open instruction set architecture (ISA) developed at Berkeley in the ParLab and ASPIRE projects.  RISC-V was originally designed to support computer architecture research and education, but  we now hope RISC-V will also become a standard open architecture for industry implementations. The base user-level ISA has now been frozen and a complete specification is available from the official RISC-V website at, along with a comprehensive collection of tools.
