"Empowering scientists, like those at NASA, with the latest in advanced computing and data analytics solutions is a key component of Supermicro's mission to make the world a better place not only for us but also for future generations," said
"This is the next step in evolving NCCS supercomputing systems for hosting ultra-high-resolution weather and climate simulations in support of
Within the NCCS, the Discover system is the primary HPC cluster and is comprised of individual compute units, referred to as Scalable Compute Units (SCUs). The most recent augmentation to the Discover cluster is SCU14 provided by Supermicro. The procurement for this system expansion was awarded to
From a performance standpoint, this deployment brings an additional 1.56 PetaFlops to NASA on top of the existing 3.5 PetaFlops for nearly 45% improvement. Compared to the previous SCU13 augmentation, SCU14 more than doubles the performance (216%) with a smaller footprint and lower TCO.
The SCU14 solution provided by Supermicro and CSRA consists of three types of nodes: compute nodes, service nodes, and I/O nodes. The compute nodes will be used to run large parallel jobs that will communicate between all compute nodes in a given phase involving several SCUs. The service nodes will be used for a variety of purposes, including but not limited to: user logins, editing, compiling, batch submission, cron jobs, subnet managers, management nodes, etc. I/O nodes provide the conduit for moving data between a Fibre Channel SAN and the compute nodes through the high-speed interconnect fabric. Compute nodes are stateful nodes with SSDs as persistent storage.
The Supermicro turn-key Rack Scale Solution for SCU14 is based on Supermicro FatTwin™ server nodes each equipped with dual 20-core Intel® Xeon® Gold processors and Intel® SSDs for persistent storage. The FatTwin™ SuperServer® is an 8-node 4U system with each node supporting 12 DIMM slots and six front hot-swap SSDs. To provide high-speed interconnect, the cluster employs Intel® Omni-Path (OPA) 100G 48-port top-of-rack managed network switches. The Supermicro 42U racks for this fully integrated HPC cluster solution are equipped with Motivair's ChilledDoor® Rack Cooling System to maximize the cooling efficiency for improved PUE.
"CSRA is excited to enter this new phase of supercomputing and help NASA engineer the technologies of tomorrow," said Executive Vice President
"Global research leaders, like those at NASA, drive new discoveries that enrich our understanding of the universe and improve the lives of everyone," said
"As a true pioneer of exploration and new technology, NASA continues to lead the way with the recent addition of its Discover system. Utilizing the latest technology, NASA recognized the need for a computer cooling system that would allow Discover to reach its full potential," states
