On the TeraGrid, what is the NSTG?
On the TeraGrid, NSTG can refer to the Neutron Science TeraGrid Gateway or the IA-32 cluster at Oak Ridge National Laboratory (ORNL) that supports it.
The Neutron Science TeraGrid Gateway is a Science Gateway dedicated to providing easy-to-use client tools and advanced data services to neutron scientists, so they can use them in their daily experimental routines. The NSTG helps neutron scientists use TeraGrid computational resources to analyze available neutron scattering datasets. A custom Java portal uses Globus and GridFTP to access TeraGrid resources, allowing developers and users to create turnkey, pre-packaged data collection and analysis workflows.
The NSTG cluster (tg-login.ornl.teragrid.org) consists
of 28 nodes, 16 of which are dedicated to running compute jobs. Each
compute node has two 3.06GHz Intel Pentium4 Xeon CPUs, 2.5GB memory,
and 26GB of local scratch space. Also, 800GB of shared scratch space
is provided across the private Gigabit interconnect. Four additional
nodes are dedicated to running GridFTP servers, and each is configured
with 4GB of memory.
The NSTG cluster is primarily intended to support local bridging activities between the ORNL engineering technology facility (ETF) and the neutron science community. However, it also part of the collective TeraGrid roaming resource.
For more, see the NSTG user guide.
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.
