HPC: Google Cloud launches 3rd generation AMD Epyc instances

Google Cloud has just added its high-performance IaaS computing services with instances based on AMD’s 3rd generation Epyc processors. These VMs are available in several cloud regions in the United States, Asia and Europe (in the Netherlands).

This fall, Google Cloud began introducing virtual machines based on 3rd generation AMD Epyc processors (formerly codename Milan) into its IaaS services. The first of its kind was launched with the Tau family, the T2D, which is optimized for workloads that require horizontal scaling out. The cloud provider then introduced these 3rd Gen AMD Epyc chips to its general purpose N2D instances, pointing out that it improved the price/performance ratio offered by 30%. It has now announced the C2D family. It offers virtual machines optimized for high-performance computing, with opportunities based on 3rd generation AMD Epyc processors, taking advantage of advances made in architecture (Zen 3 cores). The use cases are those of HPC and its intensive workloads (simulations in the pharmaceutical sector for vaccines, computational fluid dynamics (CFD), exploration of the cosmos, automation of electronic design for the industry of the future, etc.) which requires large memory, bandwidth and input/output capacities.

The C2D VM family supports persistent disks and provides bandwidths of 32 Gbits/s by default. Instances can be configured for up to 112 vCPUs (56 cores), 896 GB of memory, and 3 TB of local SSD storage. The C2D family is available in standard, high-CPU and high-mem versions, each providing 7 machine types for optimal memory-to-core ratio to suit different workloads, says Google Cloud in a post. C2D high-mem configurations are adapted for HPC and EDA (electronics design automation) workloads that require high memory capacities, while high-cpu and standard instances will suit high-performance requirements. web servers, media transcoding and developing high budget video games.

Confidential computing support is coming soon

In its post, Google Cloud compares the performance of its C2D instances based on 3rd generation Epyc (formerly codename Milan) to its N2D VMs based on 2nd generation Epyc (formerly codename Rome). The cloud provider explains that it has partnered with AMD engineers to establish a benchmark for several key high -performance computing applications, such as weather forecasting, molecular dynamics or computational fluid dynamics and to compare, in particular, the performance in floating point computing and memory. . To its users, Google Cloud cites clients such as Airshaper, a CFD platform for conducting aerodynamic simulations in the automotive industry. He said he was able to reduce costs by almost 50% and simulation times by 30% compared to the previous generation of HPC instances used.

For containerized workloads, Google Kubernetes Engine supports C2D instances. Confidential computing support will soon be available for the protection of sensitive data in process, including in-memory encryption. GCP says it is focused on providing Confidential Computing VMs and GKE and Dataproc services that provide AMD SEV (Secure encrypted virtualization) security functionality. “We will support SEV with the latest generation of Epyc processors in the medium term and plan other security capabilities in the future,” the vendor said. C2D instances are available in many cloud regions, USA, Asia and Europe, Netherlands.
