High-Performance Computing and Communications

Among supercomputers in an academic setting, HPCC's new supercomputer cluster is the 7th fastest in the United States. Among all supercomputers in the world, it is ranked 61st. It claimed this distinction by achieving a benchmark in fall 2008 of 44.19 teraflops, or 44.19 trillion floating-point calculations per second, on its 768-node, 10-gigabit backbone cluster.

HPCC comprises a diverse mix of computing and data resources. Two Linux clusters constitute the principal computing resource. In addition, HPCC has a central facility that provides more than 400 terabytes of combined disk storage and potential access to nearly a petabyte of tape storage, as well as a Condor cluster that uses spare cycles on UNIX workstations in USC's general-access computing rooms.

Solaris Cluster Decommissioning

On July 1st, the small Solaris Netra cluster will be decommissioned. Those accounts that had access to the Solaris cluster will be able to run their jobs on Almaak, following the cluster guidelines.

MPI programs compiled with mpic-bm must be recompiled with updated mpich-mx build. To see if you binaries are affected, run 'ldd $executable|grep libgm'. If "libgm" is printed, then the binary will not work without recompiling. /usr/usc/mpich/default/mx-gnu34 /usr/usc/mpich/default/mx-intel /usr/usc/mpich/default/mx-gnu4 /usr/usc/mpich/default/mx-pgi pbstop Pbstop is installed on hpc headnodes, hpc-login1 and hpc-login2 (/usr/bin/pbstop). To learn about its features, visit the manpage or help screen (type h).
