Some videos are available from Sun’s HPC Consortium which was held last year in Portland, next to the SC09 conference.
On the more interesting ones is by of the presentation by Yan Fisher, who is Benchmark Lead in Sun’s Technical Marketing Systems Group. His presentation is an update on benchmarking in HPC.
Head on over to Sun’s HPC Watercooler to watch it.
Over at the Sun HPC Watercooler there’s a great video from Acumen CTO Professor Erik Hagersten about how to migrate legacy code to multicore architectures, and how to optimise performance for parallel architectures.
Finding single core processors in servers is almost impossible now, and with processors like Sun’s UltraSPARC T2+ and NVidia’s GPU solutions, parallel processing (and the associated performance issues) are going to be a hot topic over the next few years.
The full video can be viewed here - well worth a watch.
One of the problems using big disk arrays is the difficulty in getting meaningful reporting out of them. All the vendors’ tools are closed source, and in many cases the expertise from the vendor is often missing or seriously lacking when it comes plotting performance trends.
“Just add more cache” is the same tired refrain vendors always give. No. I’m not going to recommend to clients that they spend a huge sum of money buying more SAN cache until I can prove the SAN actually needs it.
In March 2004 I wrote an article for SysAdmin Magazine showing how to use the symcli command line tools in conjunction with Orca to plot some nice historic performance graphs, showing the host’s view of performance of the Symmetrix array.
