ARCHIVED: On XSEDE, what is CTSS?

Coordinated TeraGrid Software and Services (CTSS) is a set of software packages and services implemented on various Extreme Science and Engineering Discovery Environment (XSEDE) compute, visualization, and data digital resources. CTSS software is grouped into task-oriented Capability Kits, each implementing a set of related capabilities based on the needs of researchers, such as running jobs, moving data, or computing remotely.

Since XSEDE is a collection of heterogeneous resources, not all resources may be appropriate for a specific task, and hence not all kits are available on all systems. The CTSS Core Integration Kit is available on all XSEDE resources, as each XSEDE resource is required to implement it. This kit provides a minimal set of capabilities that allow coordinated operation of the XSEDE system by XSEDE staff.

To determine which Extreme Science and Engineering Discovery Environment (XSEDE) digital services have this application installed, use the XSEDE User Portal Software Search. Enter the application name in the Search software box. As you type, search results (i.e., systems with that application installed) are returned automatically. To list all available applications, leave the Search software box empty, and then sort the results by digital service (click Resources), category (click Science Category/Domain), or Service Provider (click Sites).

Similarly, to determine whether an XSEDE Science Gateway provides access to this application, use the search tool on the Gateway Applications page in the XSEDE User Portal.

If this application is not listed, most likely it is not installed on any XSEDE digital services nor accessible from any XSEDE Science Gateways. If a scientific application that is integral to your research is not available, or if a necessary module associated with an installed package is not available, contact the XSEDE Help Desk to request its installation.
