Hi Devon, I'm sort of in awe of people who give lectures ... it is my one weakness. Actually, I'm really terrible at public speaking.
I would appreciate it if I can get a copy of your paper after you've given your talk.. This last few years, I've gotten off track with parallel processing for J. My strategy was to move the calculations to the client machines instead of the server. This has worked since lowest end client machines are dual-core PC with at least 1.6GHz CPU's. Of course there are caveats like I have to bring down huge chunks of data from the server (sometimes over the internet) to the client machine for processing and then send the result back up for saving. Still, there is something to be said when processing is done on a big iron server rather than a generic clone desktop. The performance difference is really big and particularly with data marshaling from the server to the client pc and vice-versa. r/Alex -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Devon McCormick Sent: Wednesday, August 18, 2010 12:44 PM To: [email protected] Subject: Re: [Jbeta] jhs and concurrency I'm giving a talk in Berlin next month on using J to take advantage of multi-core machines. Much of what I'm talking about I've discussed at NYCJUG over the past five or six months - some of it is on the wiki. The short message is: the tools are there and it can be done; I've gotten good results just trying some of the simplest things that occurred to me - spinning off separate processes on a crude division of work - but it doesn't come for free. The title of my paper is "Parallel Processing: Toward a Practicum" because I find it useful to have specific examples and others may as well. I'll have more to present on this after I've given my talk but the basic material is already out there.
