On the TeraGrid, what is Pople?

On the TeraGrid, Pople is the SGI Altix 4700 shared-memory NUMA system at Pittsburgh Supercomputing Center (PSC).

Pople consists of 192 blades, with each blade holding two Itanium2 Montvale 9130M dual-core processors for a total of 768 cores. The four cores on each blade share 8GB of local memory. The processors are connected by a NUMAlink interconnect. Through this interconnect, the local memory on each processor is accessible to all the other processors on the system. Each processor runs an enhanced version of the SuSE Linux operating system. There are multiple front-end Itanium2 processors running the same version of SuSE Linux as the compute processors. Logins are to one of these front-end processors, not to the compute processors.

The Intel C, C++, and Fortran compilers, and the Gnu C and C++ compilers are installed on Pople, as are the facilities to enable you to run OpenMP, MPI, and hybrid OpenMP and MPI programs.
