Video: Solarflare and Altera Building Custom Compute Platform

One of the criticisms of FPGA computing for HPC has been a lack of useable programming tools. In this video, Russell Stern from SolarFlare describes how the company leveraged its experience with Altera FPGA tools for its AOE ApplicationOnload Engine. Computers have always been able to perform specific tasks with the addition of application software. […]

Dr. Bandwidth on Cached Access to Memory-mapped IO Regions

Over at John McCalpin’s Blog, “Dr. Bandwidth” has posted an in-depth look at memory-mapped IO (MMIO). For tightly-coupled acceleration, it would be nice to have the option of having the processor directly read and write to memory locations on the IO device. The fundamental capability exists in all modern processors through the feature called “Memory-Mapped […]

CUG Best Paper Describes Trillion-Particle Simulation on Hopper

The Cray User Group wrapped up in Napa Valley earlier this month with a team from NERSC winning best paper: Trillion Particles, 120,000 cores, and 350 TBs: Lessons Learned From a Hero I/O Run on Hopper. An unprecedented trillion-particle simulation, which utilized more than 120,000 processors and generated approximately 350 terabytes of data, pushed the […]
