PNNL signs on the line for an 18,000 core Opteron machine from HP

HP announced today that the Pacific Northwest National Laboratory is installing a 163 TFLOPS system focused on research in the environmental molecular sciences. At that size it likely would have earned the number two slot on the June Top500 list.

From the release

The new system will provide the high-performance engine to enhance research in aerosol formation, bioremediation, catalysis, climate change, hydrogen storage and subsurface science in support of the Department of Energy’s (DOE) missions in energy, environment and national security.

Stats? You bet:

The supercomputer architecture runs on an HP ProLiant server and includes an InfiniBand 4x DDR interconnect, 4,620 AMD Opteron processors, 37 terabytes of memory and aggregate disk bandwidth of about 950 gigabytes per second enabled by nearly 21,000 disk drives in HP enterprise virtual arrays. Consisting of 18,480 2.2 gigahertz AMD Opteron processor cores, the new HP supercomputer will have an expected total peak performance of about 163 teraflops.

I believe this machine is the largest Barcelona-based system announced to date (as pointed out in the comments, TACC’s machine is way bigger). PNNL is one of the 10 national laboratories managed by DOE’s Office of Science.

    It’s not even close to the largest Barcelona-based machine announced. The TACC Ranger machine will have over 50K cores.

  2. Jim – you are absolutely right. I spaced on the TACC machine. Thanks.
