October 27: John Schiavone, Cadence Design Systems: Real World Parallelism:

Hi Everyone,

I thought that I would post this since one of my co-workers at Cadence will be gave a webinar on his experience parallelizing an existing application. The application and algorithms involved are really complex. It was especially interesting because it involves legacy code and also the development environment was Windows unlike many EDA applications which run on Linux/Unix. I really recommending watching.


Parallelizing Legacy code using Fine Grained Distributed Processing

Adding parallel processing to legacy code is a desire of every software company that has an existing product which is significant in complexity and which needs to run faster. Processor clock rates are not increasing much and now multiple cores are being added to chips instead. The problem of speeding up software is moving from a hardware improvement problem to a software parallelization problem. This is a follow-on post to Why Parallel Processing? Why now?

Why Parallel Processing? Why now? What about my legacy code?

Many software companies have applications which are in use by their customers that have significant runtime and for which fast runtime is a necessity or a competitive advantage. There has always been the pressure to make such applications go faster. Historically, as processors have increased their speed, the needed speedups could often be achieved by tuning the single cpu performance of the program and by utilizing the latest and fastest hardware.
