Keeping up with High Performance Computing’s ever-expanding horizon, with a chance of clouds. ☁️

Google Cloud HPC Toolkit

Google’s Cloud HPC Toolkit allows admins to define a cluster in YAML and their ghpc command-line tool combine various Google-maintained and community Terraform modules to produce a static directory of Terraform to apply, tear down and apply again! Modules already exist to have a fully working Slurm batch scheduler, optionally in federation with your OnPrem cluster, with a wide array of software support available, including Spack and Intel’s OneAPI suite.

Taking advantage of the best of cloud these clusters are capable of autoscaling and can take advantage of Google Cloud’s services and partners.

All using industry standard tooling: HashiCorp’s Terraform & Packer, implementing Google’s best practices in SRE .

AWS ParallelCluster 3.2 adds Slurm memory-aware scheduling and expands filesystem support

Slurm-based memory-aware scheduling in AWS ParallelCluster 3.2 by Oliver Perks

tldr; --mem and --mem-per-cpu job flags are now available!

Expanded filesystems support in AWS ParallelCluster 3.2 by Oliver Perks

ParallelCluster already has support for  Amazon Elastic File System (EFS) Amazon Elastic Block Store (EBS)  and  Amazon FSx for Lustre . In this release we added support for the  FSx for NetApp ONTAP  and  FSx for OpenZFS  filesystems.

With this ParallelCluster 3.2, you can now mount up to 20 Amazon FSx file systems and up to 20 Amazon EFS filesystems.

Rocky Linux on Google Cloud as fully supported alternative to CentOS

Moving off CentOS? Introducing Rocky Linux Optimized for Google Cloud

As CentOS 7 reaches end of life, many enterprises are considering their options for an enterprise-grade, downstream Linux distribution on which to run their production applications. Rocky Linux has emerged as a strong alternative that, like CentOS, is 100% compatible with Red Hat Enterprise Linux.

John C. Linford publishes a comprehensive Getting Started with NVIDIA Arm HPC Developers Kit

Getting started with HPC on Arm64 | GitHub

This guide includes how-to guides, sample code, recommendations, and technical best practices to help new users get started with Arm-based systems like the NVIDIA Arm HPC Developer Kit. While it is intended for the users and administrators of NVIDIA’s Arm-based platforms, this guide is also generically useful for anyone running HPC applications on Arm CPUs, with or without GPUs. The focus is mostly on the CPU since Arm-hosted GPUs are just the same as GPUs hosted by any other CPUs.
