Nothing significant - there was a small bump for flat-quad mode from a previously measure peak of 435 to 449 GB/s but this is only 3% and more or less in the noise range of the measurements. SNC-4 mode continues to exhibit problems with one of the NUMA domains being slower and peak bandwidth of 440 GB/s only achievable with 128 threads (vs 64 threads for peak of very close to peak in other modes). Cache mode wasn't tested. -Scott On 5/23/16 4:08 PM, Delalondre Fabien Jonathan wrote:
Did you observe any performance improvements for STREAM ?

We're done testing. Sorry for taking the machine away for a bit longer than expected.

This work is done. Note, we're still doing a few benchmarks to see if the BIOS has fixed any of our standing issues.
Also, this BIOS update renamed the BIOS parameters for the Memory Model and Mode. They are now "Memory Mode" and "Cluster Mode". The Wiki has been updated to show this.
A separate Intel Vtune 2016 copy has been installed under /soft/restricted/intel-vtune-nda. This install contains the Intel NDA KNL add-on. I've not tested it, so please let me know if it works. I have compiled the sep4_0 kernel module from this VTune install, and set knl00 the load it on boot.
