TACC is also a partner in HiPCAT -- High Performance Computing Across Texas -- a consortium of Texas institutions that use advanced computational technologies to enhance research, development, and educational activities. These advanced computational technologies include traditional high performance computing (HPC) systems, in addition to complementary advanced computing technologies including massive data storage systems and scientific visualization resources. The advent of computational grids -- based on high speed networks connecting computing resources and grid 'middleware' running on these resources to integrate them into 'grids' -- has enabled the coordinated, concurrent usage of multiple resources/systems and stimulated new methods of computing and collaboration. Our principal project in the area of grid computing is the Texas Internet Grid for Research and Education (TIGRE), the public documentation and user portal for which is available at tigreportal.hipcat.net. HiPCAT also explores other areas of technological and organizational interest to its members.
