Specifications:

Nemo has 7000 processor cores which provide a peak theoretical performance of 56 teraFLOPS of computing power:

  • 8 nodes running modern GPUs that can perform matrix operations and Fourier transforms much faster than a traditional CPU. In addition, these nodes have 32 Intel Xeon E5-2650 cores running at 2.0GHz and 64GB of RAM. Deployed in Fall 2012.
  • 84 nodes with 32 Intel Xeon E5-2650 cores running at 2.0GHz and 64GB of RAM. Deployed in Fall 2012.
  • 160 nodes, each with 24 Intel Xeon X5650 cores running at 2.7GHz, 48 GBytes of RAM, 1000GB SATA disk. Deployed in fall 2010.
  • 500 TBytes of storage (about 300 TBytes of Sun X45xx servers and 200 TBytes of inexpensive data servers).
  • The system is networked with a Force10 E1200 ethernet switch; all equipment is connected to a 500kVA/400 kW UPS system; four Data-Aire 26-ton air conditioning units cool the data center.

Funding:

  • An upgrade of Nemo was funded on August 17, 2009 by a Major Research Instrumentation grant from the National Science Foundation ($1,188,018) and by matching funds from UW-Milwaukee ($509,150). Approximately half of the funds were spent on upgrades in 2010 and the remaining half in 2012.
  • Nemo was funded on July 20, 2004 by a Major Research Instrumentation grant from the National Science Foundation ($1,444,972) and by matching funds from UW-Milwaukee ($446,093). UW-Milwaukee also provided the space for the data center. The anticipated lifespan of the computing nodes was 3-5 years.
