Ask the Experts: Effective Use of Multi-core in HPC
Suffering from multi-core anxiety syndrome (MCAS)? Need honest answers to you infrastructure questions? Want to pick the brain of an expert? Join the live discussion and let our panel put you on the right track.
Monday, December 10th, 2007
One of the biggest challenges facing many HPC practitioners is how to leverage the full potential of multi-core design without having to re-write their current MPI-based applications. Everyone knows multi-core is the future, but at what cost?
Unlike other market sectors, the HPC community has a large base of “parallel code” that has already been ported to work on multiple processors (or cores). This panel discussion will focus on how to quickly and efficiently translate these codes to multi-core environments, minimizing the number of changes to existing application environments.
Discussion topics include:
- MPI runtime strategies;
- Reasonable performance expectations;
- Comparison of MPI and OpenMP on multi-core nodes; and
- Your questions.

After you register it shows a page that says that the time is 3pm PST instead of 10am PST. It is ok on this page though.
Unfortunately this webinar requires realplayer.
@jlfose, the time for the live event on this page is correct (I know it’s correct b/c I wrote the code to do the timezone translation, natch ;-). Thanks for the catch.
@ben_dash, the webinar does require Real Player, which you can get for free for just about any operating system. We realize that Real Player isn’t everyone’s favorite app but, on the bright side, the webinar doesn’t require Windows Media Player. :-)
Thats ironic. My company would allow me to watch over WMP, but not over Real.
@Jeremy, that’s not irony, that’s just unfortunate.;-)
Seriously though, I think I confused things in my last post. Real is only required if you are using Linux. Real is NOT required if you are using another OS. The webinar is also available via WMP.
I have Realplayer on my Mac, but the test app is unable to find it.
hi, broadcast homepage not working at macosx, realplayer works fine on this machine and the test too. Just no feed there is on the link mailed
Anyway, my question of course is: how do you see in the coming years clusters keep up in bandwidth with the cpu’s?
We’ll get probably cpu’s that have tens if not hundreds of cores, good in floating point streaming.
How do clusters keep up with their network with that huge bandwidth that a single cpu is going to generate in highend for number crunching / matrix calculations?
Another question is price. You can buy great quadcore nodes now for like 600 euro with 4GB ECC ram. Highend networks on the other hand have usually a node price of 1000+ euro, not seldom a lot higher for bigger clusters.
Can we expect any breakthrough’s there?
Kind of incredible to need realplayer to watch a HPC conference in linux magazine, it is just a pain for a linux user…
@moatdib Because of how the audio and slides need to stay in sync and in order to deliver in-presentation features like polling questions, we have to use an application like RealPlayer (or WMP).
Hi, will this webinar be archived? I wanted to attend, but I miscalculated the time, and I don’t think I will be able to attend the live webinar. Thanks.
Ah, well, timezones are a pain, but actually I think I didn’t miscalculate, but rather the GMT time for this webinar is incorrect. The info says it is at 5:00 PM GMT, but that would be 09:00 EST according to http://wwp.eastern-standard-time.com/
Anyway, I’ll try to see the archived version later on. Cheers.
Are the slides from this webinar available for viewing?
The archive for this webinar is now online. Slides and Q&A included.
webinar required windows client [macos realplayer and linux realplayer both failed to run the slides correctly]. How HPC was that?
@arnoldgncsa, you might check out the system requirements the webinar help page:
http://event.on24.com/view/help/ehelp.html
I’m using a rather slugging version of 10.3 and I can view the archive.
This is one of those problems that I don’t think that apply any amount of HPC would fix. :-)
I’m new to this site. But I’d like to see this Webinar. Where are the archives. I probably missed the obvious place to look.
Thanks.
