Hi Ray, We should be able to accommodate this. Please request a new JLSE resource via http://press3.mcs.anl.gov/jlse/projects/project-request-form/. Under Resources/Test Bed Needed, "Upgrade existing E5-2603v3 JLSE machine "snell" with E5-2620v3 CPUs add four more DIMMs to fully populate memory channels, cost will be $1610.52 via MNJ Tech in AMOS." I also suggest looking into the E5-2650L. It's actually the best flops/watt CPU in the entire line-up. Albeit it is quite a bit more expensive than the E5-2620v3. If your applications are memory bandwidth bound, I'd look at models that support DDR4-2133. Lastly, I'm not sure what vendor or what level/type of hardware you're looking for, but Intel has a really nice 4 node in 2RU system: http://www.intel.com/content/www/us/en/motherboards/server-motherboards/serv.... Thanks, Ben

P.S. The aim is to determine the best price-performance for a 60-node addition to Blues for reactor research.

We would like to compare the 6-core Haswell against our 8-core Sandy Bridge for a floating-point intensive benchmark.

Hi Ray,

Not specifically the E5-2620v3. JLSE has one machine with 2x E5-2603v3 (6c, lower clock rate, and lower memory bandwidth), and 8 machines with 2x E5-2699v3. What are you trying to test with the E5-2620v3?

If needed we could upgrade the machine that has the E5-2603v3 CPUs to E5-2620v3. Cost would be $843.72.

Note, I'm pretty sure all 4-8 core Haswell-EP CPUs have a single memory controller.

Hi Ben,

Does anyone here have the 2620v3 Haswell with 6 cores and 1 memory controller on chip?

All,

We've added six systems that each have two Intel Haswell-EP 18c E5-2699v3 CPUs. These CPUs are interesting as they are the first Xeon based system that has greater than a teraflop of performance.

Hostnames: thing{00,01,04,05,06,07}.ftm.alcf.anl.gov

- SuperMicro SC747BTQ-R1K62B 1600W 4RU Chassis - SuperMicro X10DRi Motherboard - 2x Intel Xeon E5-2699v3 18c CPU - RHEL7 (3.10.0-123.6.3.el7.x86_64)

Note, currently these machines do not have an IB connection. We're hoping Mellanox will loan us new EDR hardware for these nodes.

We're waiting on a replacement for a failed CPU on "thing02", and Kaz has "thing03" in Tinkerlab.

Let me know if you run into any issues.
