CTSS capabilities on Blue Gene/L
Coordinated TeraGrid Software and Services (CTSS) is bundled into individual kits, each enabling resource functionality for a specific set of services and user and system interfaces. Individual resource providers choose the kits they want to support for their resources, and thus select the services and components provided to the community.
Frost supports the following CTSS kits: Core Integration, Remote Login, Remote Compute, Application Development and Runtime Support, Data Movement, Parallel Application Support, Science Workflow Support, and the Wide Area GPFS File Systems Kit. These kits comprise the full set of functionality expected for a computational resource.
This image shows a two-week sample of
automated test suite results for a portion of the supported kits on frost,
NCAR's computational resource on the TeraGrid. The GPFS-WAN kit does not
have an automated test suite. Additionally, some software components are
not supported by the Blue Gene/L architecture, which is reflected in the
sub-100% status results shown for the Parallel Application Support kit. The
change in results between successive Remote Compute results reflects a
transient error in the test during the previous period.
During FY2008, several of these kits were upgraded as part of the normal upgrade process: Data Movement (upgraded twice), Remote Compute, Core Integration, and Application Development and Runtime Support.
For the FY2009 period, the CISL ReSET team will continue to track updates and developments to these kits and upgrade when necessary, as well as provide input and feedback on modifications to the current kits and the development of new kits.
