This Week in HPC: Cray Unveils Next Generation Supercomputer and DDN Extends Product Line with Scale-out Appliance

this week in hpc

In this episode of This Week in HPC, Michael Feldman and Addison Snell from Intersect360 Research discuss the next generation Cray XC40 supercomputer with DataWarp technology as well the introduction of a new Scale-out Storage Appliance from DDN based on GPFS.

Burst Buffers and Data-Intensive Scientific Computing

Glenn Lockwood

“For those who haven’t been following the details of one of DOE’s more recent procurement rounds, the NERSC-8 and Trinity request for proposals (RFP) explicitly required that all vendor proposals include a burst buffer to address the capability of multi-petaflop simulations to dump tremendous amounts of data in very short order. The target use case is for petascale checkpoint-restart, where the memory of thousands of nodes (hundreds of terabytes of data) needs to be flushed to disk in an amount of time that doesn’t dominate the overall execution time of the calculation.”
