DiRAC Extreme Scaling (Tesseract)¶
DiRAC Extreme Scaling (also known as Tesseract) is available to industry, commerce and academic researchers. For information on how to get access to the system please see the DiRAC website.
The Tesseract compute service is based around an HPE SGI 8600 system with 20,256 cores. There are 844 compute nodes, each with 96 GB of memory, connected together by a single Intel Omni-Path Architechture fabric. Each node contains two 2.1 GHz, 12-core Intel Xeon (Skylake) 4116 processors, and all nodes access the 3 PB Lustre file system.
This documentation covers:
- Tesseract User Guide: general information on how to use Tesseract
- Software Libraries: notes on compiling against specific libraries on Tesseract. Most libraries work as expected so no additional notes are required however a small number require specific documentation
Information on using the SAFE web interface for managing accounts and reporting on your usage on Tesseract (and DiRAC as a whole) can be found on the DiRAC SAFE Documentation
