The original Lonestar was a 50-gigaflops Cray T3E with 88 processsors. With Lonestar 5, TACC is installing a Cray XC40 machine with more than 30,000 Intel Xeon processing cores delivering 1.25 petaflops of computing power. Specs include 1,252 nodes of dual-socket 12-core Intel Xeon E5-2600 v3 processors, two large shared memory nodes with 1 TB each, eight large shared memory nodes with 500 GB each and a 1.2 PB DDN storage system, running on Cray Aries interconnect. The system will replace the Dell PowerEdge-based Lonestar 4 in serving Texas researchers with a wide variety of application needs.
The HPC director added that while TACC supports all kinds of users, there is an effort underway to serve the bio- and bio-med community. With the ability to support protected data formats related to the Health Insurance Portability and Accountability Act (HIPAA) and the Federal Information Security Management Act (FISMA), the system can be used for both electronic health records and HPC-driven clinical work. In line with this, Lonestar 5 will be an important resource for a new medical school coming to the UT Austin campus in 2016.
