Genome InsiderThe Megadata of Lake Mendota - Part 2: Souped Up ComputingThis series is the story of a giant metagenome assembly from Wisconsin’s Lake Mendota. In this episode: a look at the supercomputing that stitches together large datasets with the assembler program MetaHipMer2.Oak Ridge National Lab is home to two supercomputers — Summit and Frontier — that process terabytes of data with MetaHipMer2. And the National Energy Research Scientific Computing (NERSC) has another supercomputer, Perlmutter that works at large scale. But nearby the JGI, a cluster called Dori is also capable of running smaller assemblies — so we head there for a sense of what this supercomputing looks like.

Radio HPC: The Rich ReportAI and the Virtuous Cycle of ComputeIn this Rich Report podcast, Pradeep Dubey discusses AI & The Virtuous Cycle of Compute.
Traditionally, there has been a division of labor between computers and humans where all forms of number crunching and bit manipulation are left to computers, whereas intelligent decision-making is left to us humans. We are now at the cusp of a major transformation that can disrupt this balance. This disruption is triggered by an unprecedented convergence of massive compute with massive data, and some recent algorithmic advances. This confluence has the potential to spur a virtuous cycle of compute.
Deep Learning was recently scaled to...

RCE - Super ComputersRCE 113 ShifterShifter is a prototype implementation that NERSC is developing and experimenting with as a scalable way of deploying containers in an HPC environment. It works by converting user or staff generated images in Docker, Virtual Machines, or CHOS (another method for delivering flexible environments) to a common format. This common format then provides a tunable point to allow images to be scalably distributed on the Cray supercomputers at NERSC. The user interface to shifter enables a user to select an image from their dockerhub account and then submit jobs which run entirely within the container.
