Faster Computing Results Without Fear of Errors

Interesting look at how to minimize errors in computing, could be especially useful if it included security aspects.

Faster Computing Results Without Fear of Errors

MIT News  Adam Zewe, June 7, 2022

A multi-institutional team of researchers has developed PaSh, a system that can dramatically speed up certain types of computer programs while ensuring the accuracy of results. The system accelerates programs or scripts that run in the Unix shell, parsing their components into segments that can be run on multiple processors. PaSh parallelizes program components "just in time" to predict program behavior, speeding up more elements than traditional methods that attempt to parallelize in advance while still returning accurate results. The researchers tested PaSh on hundreds of scripts without breaking one; the system also ran programs an average six times faster than unparallelized scripts, and realized a nearly 34-fold maximum speed increase. ...
