Hardware Configuration
Dell PowerEdge C6525/R940
The high level of total processing power of this system is made possible by coupling multiple processors together.
Its standard configuration CPU node is equipped with AMD Rome processors with 128 cores per node, and its Fat node features large memory capacity of 3 TB per node.
The CPU servers have a total theoretical computational performance of 6.881 PFLOPS and a total main memory capacity of 420 TiB,
while the FAT servers have a total theoretical computational performance of 77 TFLOPS and a total main memory capacity of 24 TiB.
As of July 2026, the CPU server had 144 fewer nodes, resulting in a total theoretical computational performance of 6.291 PFLOPS and a total main memory capacity of 379 TiB.
