Over at Admin HPC, Intel’s Jeff Layton writes that understanding how data makes its way from the application to storage devices is key to understanding how I/O works and that monitoring the lowest level of the I/O stack, the block driver, is a crucial part of this overall understanding of I/O patterns.
“Until Docker came around some people used containers but the use was very much restricted to large organizations, like Google, that had specialized teams and training.

In this video, Bronson Messer from ORNL presents: An Introduction to OpenACC. “OpenACC is gaining momentum and adoption,” said Duncan Poole, President of the OpenACC Standards Group. “Developers benefit because using OpenACC directives makes parallel programming more productive and collaboration easier. Large, legacy codes are easier to maintain and accelerated code is more portable across HPC systems.”
