NPP1 Analysis System

The system can be accessed at npp1.nascom.nasa.gov

The NPP1 system will provide the NASA NPP Science Team with resources as follows:

• science algorithms and documents (in coordination with the NEXT system)
• data sets for algorithm testing
• necessary toolkits for data analysis and visualization
• a platform for running comparison tests and models

NPP1 Hardware

• One (1) SGI 3200 server with 8 processors and 4GB of memory
• Sixteen (16) SGI Linux boxes with dual Pentium III 700MHZ processorsand 40GB of local disk space.
• Four (4) Gigabit Ethernet Links from the SGI server to the Linuxboxes, and one outbound gigabit Ethernet Link.
• Ten (10) 480GB RAID King Hard drives in RAID configuration.

The machine is currently set up with home directories (mirrorednightly) on a single RAID King. Additional working space is available onthe other RAID King units, but they are not currently being backed up. As the NPP science team begins to utilize the system, the backup and othercapacities will be increased.

NOTE: npp1 is transitioning from SGI to a linux system in the summer of 2005.

NPP1 Software
