Main Auditorium (DESY Hamburg)

11. Performance of modern processor with HEP code

Dr michele michelotto (INFN Padova)

27/04/2007, 09:00

I compared the performance of several HEP processor from Intel and AMD when running 32bit and 64 bit code on SL4 using typical HEP code I started also a look to Spec CPU 2006 int and fp on a 4core intel processor

27. CPU Benchmarking at GridKa - Update April 2007

Manfred Alef (Forschungszentrum Karlsruhe)

27/04/2007, 09:25

I'll continue the discussion about CPU benchmarking. New topics are: - experiences with new worker nodes at GridKa, - quad core measurements, - differing levels of optimization, - first SPEC CPU2006 results.

20. Many-Core CPUs - Parallel Computing in HEP

Alf Wachsmann (SLAC)

27/04/2007, 09:55

Parallel computing in HEP is regarded as exotic and unnecessary (at best). I will talk about the recent BaBar D0 mixing results and how parallel computation helped. I will also illustrate that parallel computing will be the only way to take advantage of the upcoming "many-core" CPUs.

40. Multi-core CPU performance in High Energy Physics applications

Dr Peter Wegner (DESY)

27/04/2007, 10:20

Multi-core CPUs are the standard way for a performance efficient utilization of additional on-chip CPU space provided by advanced silicon technologies. Though this leads to a more fine grained parallel approach on the programming level for instance by introducing multithreading it is also expected that trivial parallel applications like the event processing in High Energy Physics can...
