NCCS: NCCS Computers
The National Center for Computational Sciences (NCCS)
at ORNL provides state-of-the-art resources for high-performance computational
science. The NCCS provides the National Leadership Computing Facility
(NLCF), along with capacity computing in support of SciDAC and other programs.
The NCCS offers storage resources as well as computing, networking and, visualization resources.
NCCS systems include:
- Phoenix: a Cray X1 with
512 multi-streaming vector processors and 2 TB of globally addressable
memory. Phoenix is an NLCF system.
- Jaguar: a Cray XT3 with
over 3700 processors and 2 GB of memory per processor. Jaguar is an NLCF system.
- Ram: a 256-processor SGI Altix with
2 TB of shared memory. Ram is an NLCF support system.
- Cheetah: a 27-node IBM p690
system, where each node has thirty-two 1.3 GHz Power4 processors. Most
of the nodes have 32 GB of memory, but five of the nodes have 64 GB of memory,
and two have 128 GB of memory.
- Tiger: a 144-processor Cray
XD1 with 8 GB of memory per two-processor node. Tiger has six nodes
with attached FPGA co-processors.
- Eagle: a 184-node IBM RS/6000
SP. 176 "thin" nodes have four 375 MHz Power3-II processors and 2GB of memory
while 8 "wide" nodes have two 375 MHz Power3-II processors and 2GB of memory.
Eagle was shut down June 1, 2005.
