As a persistent store, we estimate performance is ten times better on a node-per-node basis. If a parallel file system is a truck, this Fujitsu HPC platform is a race car. One is designed for capacity, the other for speed.

Co-creation project tackles I/O challenges


NEXTGenIO started in 2015 by a consortium consisting of partners EPCC, Intel, Fujitsu, Technische Universität Dresden, Barcelona Supercomputing Center, the European Centre for Medium-Range Weather Forecasts, Arm (formerly Allinea) and Arctur. Its research has bridged the gap between memory and storage, using Intel’s revolutionary Optane DC Persistent Memory, which is technically close to DRAM speed and significantly better than disk storage.


Multiple HPC systems, that communicate simultaneously with slow disk storage, limit how fast the system can read and write data, creating bottlenecks. A solution was needed to eliminate these bottlenecks for frustrated customers.


NEXTGenIO was formed to explore a new approach to HPC and Fujitsu was invited to help develop the prototype. Fujitsu designed a 34-node computing cluster using Intel® Optane™ DCPMM. Each of the 34 compute nodes is equipped with two second-generation Intel® Xeon® Scalable Family processor CPUs and 3TB of Intel® Optane™ DC persistent memory.


  • Application performance has increased up to tenfold
  • Customers’ time to results for data-intensive workloads dramatically reduced
  • Cost per capacity is lower than traditional DRAM deployments
  • Increased memory capacity compared to DDR4 configurations, offering flexible usage models
  • NEXTGenIO prototype technology is now market-ready in PRIMERGY and PRIMEQUEST models
