Video: Calligo Technologies Demonstrates Posit Computing Implementation

Anantha Kinnal from Calligo Technologies gave this talk at the ConGA conference for Next Generation Arithmetic. “CalligoTech, based in Bangalore – India, built and demonstrated World’s First Posit-enabled System at the CoNGA track at Supercomputing Asia’18, Singapore. Our primary objective was to build a System capable of performing basic arithmetic operations using Posit Number System and capable of running existing C programs.”

Universal Coding of the Reals: Alternatives to IEEE Floating Point

Peter Lindstrom from LLNL gave this talk at the Conference on Next Generation Arithmetic in Singapore. “We propose a modular framework for representing the real numbers that generalizes IEEE, POSITS, and related floating-point number systems, and which has its roots in universal codes for the positive integers such as the Elias codes. This framework unifies several known but seemingly unrelated representations within a single schema while also introducing new representations.”

John Gustafson to host BoF on Posit Arithmetic at SC17

John Gustafson from A*STAR will host a BoF on Posit arithmetic at SC17. Entitled, “Improving Numerical Computation with Practical Tools and Novel Computer Arithmetic,”  this BOF will be co-hosted by Mike Lam with discussions on tools for measuring floating point accuracy. “This approach obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.”

Radio Free HPC Looks at Posit Computing

In this podcast, the Radio Free HPC team looks at the problems with IEEE Floating Point. “As described in a recent presentation by John Gustafson, the flaws and idiosyncrasies of floating-point arithmetic ‘constitute a sizable portion of any curriculum on Numerical Analysis.’ The whole thing has Dan pretty worked up, so we hope that the news of Posit Computing coming to the new processors from Rex Computing will help.”
