Cluster@WU

The Research Institute for Computational Methods will satisfy the need for computational power in many scientific applications by a cluster of workstation (COW) called cluster@WU, with 44 IBM dx360M3 nodes. This system offers in total 544 cores and more than 1 TB of main memory (RAM).
The nodes are interconnected by InfiniBand, a high-performance transfer technology including Mellanox ConnectX-2 host channel adapters.
Each of the nodes has a local storage capacity of 450 GB (local scratch) provided by 15k disks, 24 GB of RAM and 2x Intel Xeon six-core CPU.

The HPL benchmark observed a total computing power of 5,56 TFlops.

The current operating system installed on the nodes is Debian GNU/Linux squeeze. The batch-queuing system has been updated to the Oracle Grid Engine (previously known as Sun Grid Engine) version 6.2u5. Jobs capable of running on the old system can be seamlessly executed on the new system. Thus, login and submission procedures will remain unchanged.

The R software package is pre-installed and up to date. Users can choose from two different installations and two flavors:
o R compiled by GCC.
- patched version accessible via R-g
- devel version via R-g-<date_of_compilation>
o R compiled by Intel compiler suite and linked against Intel MKL
- patched version accessible via R-i
- devel version via R-i-<date_of_compilation>
