The Beast of the Middle East: up to 20 times faster than predecessor, that's 884,736 CPU cores across the system
KAUST is said to be building on the success of its first supercomputer, Shaheen I, which launched in 2009. This was followed by Shaheen II, a Cray-based computer claimed to be 25 times faster than its predecessor at 5.54 petaflops.
Although Shaheen III is tipped to be fully operational in 2023, HPE told us that KAUST has not signed off on a final design yet. It is expected to comprise 25[PDF], 18 of which will hold CPU compute nodes, and 7 will be dedicated to GPU compute nodes. The CPUs in this case are planned to be AMD’s next generation Epyc chips, code-named “Genoa”, which are set to have up to 96 cores. That makes for a grand total of 884,736 CPU cores across the entire system.
As with other Cray EX deployments the nodes are linked using HPE’s high-performance Slingshot interconnect technology, and each cabinet uses closed-loop liquid cooling. Storage for the system is expected to comprise Craystorage system nodes that will add 50 petabytes of storage capacity to the KAUST site.
