PPPL Cluster Hardware
The cluster consists of several sub-clusters.
kestrel - the main cluster.
This group of 180+ systems, linked as a beowulf cluster, provides the
majority of PPPL's scientific computing hardware. Each system
contains an AMD Opteron dualcore CPU (2 CPUs), and at least 2GB of
memory. 64 systems have 4GB of RAM.
Systems are linked via a low latency, high performance 1 gigabit cluster interconnect.
kite - a larger
memory cluster with a very high speed (10Gb) low latency interconnect. This group of 24 systems, each with two AMD Opteron
CPUs and 6 GB of memory, are all linked via Infiniband (10Gb), and (by default)
gigabit ethernet.
sque - a pool of systems
reserved for single CPU jobs. These systems each contain two CPUs and
between 1 and 4 GB of RAM.
ganesh - a pool of systems
reserved for large memory jobs. These systems each contain four CPUs and
between 16 and 32 GB of RAM.
