High Performance Computing Center Program (HPCMP) Navy DoD Supercomputing Resource Center (DSRC) IBM cluster 1600 system (Babbage).
Babbage has 3072 total 1.9 GHz CPU’s Power5+ processors. Babbage uses a proprietary network and IBM's High Performance Switch (HPS), also know as Federation, to communicate between nodes. The switch provides ~7-14 microsecond latency with a raw bandwidth of 2 GBps.

Current LIS development efforts
The generic LIS-DA framework already includes the NASA/GMAO EnKF module, and has been demonstrated for soil moisture and snow examples (Kumar et al., AWR 2008):
Added Tskin EnKF plug-in and NASA/GMAO bias estimation module.
EnKF and direct insertion algorithms already included in latest LIS Version 6.0 release
New RTM extensible interface
To add RTM, implement required interfaces
CRTM added as first RTM to LIS
Simulates satellite-observed radiance
Supports numerous sensors
