On the TeraGrid, what is Mercury?

Note: For Mercury, the web server at Indiana University that hosts personal web pages, see At IU, what is Mercury?

On the TeraGrid, Mercury (tg-login.ncsa.teragrid.org) is the IA-64 Linux cluster at the National Center for Supercomputing Applications (NCSA). It consists of 887 IBM nodes running SuSE Linux:

• 256 nodes have dual 1.3GHz Intel Itanium 2 processors, half with 4GB of memory per node and the other half with 12GB of memory per node.
  
  
• 631 nodes have dual 1.5GHz Intel Itanium 2 processors with 4GB of memory per node.

Mercury uses Myricom's Myrinet cluster interconnect network and the GPFS parallel file system. It is intended to run applications of moderate to high levels of parallelism (particularly those needing a 64-bit environment), and codes that perform well in a distributed cluster environment.

For more, see the Mercury user documentation.

Note: This is a TeraGrid Roaming resource. See the TeraGrid User Support documentation for a dynamically generated list of all Roaming resources.

As part of the transition to TeraGrid XD, this resource will be decommissioned in the near future. For decommission dates of retiring TeraGrid systems, see the XD Transition page on the TeraGrid web site.

For further information about compute and visualization resources on the TeraGrid, see the Resource Catalog in the TeraGrid User Support documentation.
