Segfault

Topology of TETHYS

Hardware Topology

Description

Our segfault system is a Fujitsu-Technology PRIMERGY RX600 S6 machine mainly intended for simulations in the context of computational seismology. It is an Intel Westmere-EX based machine with 40 cores that can run 80 threads (near) simultaneously making use of Intel's hyper-threading technology.

The figure on the right, which was generated with the lstopo tool of the Portable Hardware Locality (hwloc) package, provides an overview of the hierarchical hardware topology of the system.

Further system specifications are listed in the table below:

Hostname segfault.geophysik.uni-muenchen.de
CPU type Intel Xeon E7-4860 (2.27GHz)
CPU sockets 4
CPU cores 40
CPU threads 80
RAM 256 GB
Local scratch space 2 TB
Commissioned October 2011
