Video: I/O Architectures and Technology

Glenn Lockwood from NERSC gave this talk at ATPESC 2019. “Systems are very different, but the APIs you use shouldn’t be. Understanding performance is easier when you know what’s behind the API. What really happens when you read or write some data?”

ISC 2019 Recap from Glenn Lockwood

In this special guest feature, Glenn Lockwood from NERSC shares his impressions of ISC 2019 from an I/O perspective. “I was fortunate enough to attend the ISC HPC conference this year, and it was a delightful experience from which I learned quite a lot. For the benefit of anyone interested in what they have missed, I took the opportunity on the eleven-hour flight from Frankfurt to compile my notes and thoughts over the week.”

Video: Solving I/O Slowdown and the “Noisy Neighbor” Problem

John Fragalla from Cray gave this talk at the Rice Oil & Gas Conference. “In Oil and Gas, when using shared storage, mixed workloads can have a big impact on I/O performance causing considerable slowdown when running small I/O alongside large I/O on the same storage system. In this presentation, Cray will share real benchmark results on the impacts of the “Noisy Neighbor” application has on sequential I/O, and with the right storage tuning and flash capacity, how to optimize the storage to meet the demanding workloads of Oil and Gas to accelerate performance for a mixed workload environment.”

Video: A Glimpse into the Future of I/O

In this video from the DDN User Group at SC18, Sven Oehme from DDN presents: A Glimpse into the Future of I/O. “IME is DDN’s scale-out flash cache that is designed to accelerate applications beyond the capabilities of today’s file systems. IME manages I/O in an innovate way to avoid the bottlenecks and latencies of traditional I/O management and delivers the complete potential of flash all the way to connected applications. IME also features advanced data protection, flexible erasure coding and adaptive I/O routing, which together provide new levels of resilience and performance consistency.”

Let’s Talk Exascale: Optimizing I/O at the ADIOS Project

In this episode of Let’s Talk Exascale, researchers from the ADIOS project describe how they are optimizing I/O on exascale architectures and making the code easily maintainable, sustainable, and extensible, while ensuring its performance and scalability. “The Adaptable I/O System (ADIOS) project in the ECP supports exascale applications by addressing their data management and in situ analysis needs.”
