HS06 Measurements Performed at AGLT2

We have made a variety of measurements at AGLT2 during September of 2009 in preparation for the upcoming purchase cycle. We present these here in table form. A pdf plot of these November, 2009 data is attached at the bottom of this page.

The usatlas compilation of all results is at http://www.usatlas.bnl.gov/twiki/bin/view/Admins/HepSpecBenchmarks.html

Some results at BNL are at https://web.racf.bnl.gov/Facility/LinuxFarm/specint/HEPSPEC/

July, 2013 (and later), 32-bit, SL6.4

These results include HS06 benchmarks run at other, indicated sites

* These values are scaled up by 1.128 to account for a missing pair of executables that failed to compile in the HS06 run. This factor is based upon runs over the other SkyLake processors where access was maintained.

The Gold 6132 28 core results are meant to simulate the HToff result for that processor.

We note that with Hyper Threading ON we get the best total machine performance, and that total performance is nearly sustained whether we run 12 threads or 16 threads on the 16 cores that present this way.

We also note that with Hyper Threading ON we cannot run 16 production threads in this configuration as that results in less than 2GB of RAM per core.

Using 1066MHz RAM results in an approximately 3% performance hit vs the 1333 RAM.
