Newer Supercomputers called Catalyst is built by the U.S. department of Energy, along with Cray and Intel. Catalyst is the first Supercomputer to replace traditional DRAMs with Solid State drives. This supercomputer will be deployed by the end of this month at Lawrence Livermore National Lab in California.
The new super computer has a jaw-dropping SSD storage space of 281TB broken into 324 nodes. Each nodes will be utilizing Intel Xeon E5-2659V2 12-Core processors- that’s 7,776 CPU cores- and 128GB of DRAM in each node. 304 nodes will be using 800GB SSD storage, whereas 12 more nodes will be utilizing 32.TB SSD. This will help to create a throughput of 512GB/s, which matches the 3rd fastest super computer ‘Sequoia’ present the same lab. The system is developed in a way that memory arrays are mapped into DRAMS and SSDs. This super computer will be using Intel’s 910 series SSDs with 800GB storage space per PCIe 2.0.
The CTO for technical computing group for Intel Mark Seager pointed out that this was an inevitable trend. He said,”As processors get faster with every generation, the bottleneck gets more acute.”
Catalyst was made to solve problems in the fields of bioinformatics, analytics and natural language processing.
This isn’t the first time SSDs are used in the place of DRAM. Facebook developed their own prototype server. However the implementation, throughput and processing power of Catalyst is significantly larger.
