AMD solutions for the HPC Toolkit

AMD-Optimized Slurm Cluster

This example provisions a Slurm cluster using the AMD-based Computed Optimized "c2d" family of VM types. Additionally, it will install Spack and a script to install the AMD Optimizing C/C++ and Fortran Compilers (AOCC). Installation of AOCC requires acceptance of an End User License Agreement as described below.

Provisioning the AMD-optimized Slurm cluster

Identify a project to work in and substitute its unique id wherever you see <<PROJECT_ID>> in the instructions below.

Initial Setup

Before provisioning any infrastructure in this project you should follow the Toolkit guidance to enable APIs and establish minimum resource quotas. In particular, the following APIs should be enabled

  • file.googleapis.com (Cloud Filestore)
  • compute.googleapis.com (Google Compute Engine)

You must have available C2D CPU quota (available = maximum - used) in the region you intend to provision instances:

  • low_cost partition
    • C2D CPUs: 40
  • compute partition
    • C2D CPUs: 5600
  • login and controller nodes
    • C2D CPUs: 8
  • Total
    • C2D CPUs: 5648

Additionally, the blueprint provisions 2048GB of Filestore instances in the region.

The quotas are not enforced on a partition until a cluster scales up beyond the initial CPUs used by the login and controller nodes. If you do not plan on using the compute partition, you may ignore its quota requirements.

Deploying the Blueprint

Use ghpc to provision the blueprint, supplying your project ID:

ghpc create --vars project_id=<<PROJECT_ID>> hpc-cluster-amd-slurmv5.yaml

It will create a directory containing a Terraform module. Follow the printed instructions to execute Terraform.

Run an OpenFOAM test suite

Browse to the Cloud Console and use the SSH feature to access the Slurm login node. A script has been provisioned which will activate your OpenFOAM environment and run a test suite of applications. The output of this test suite will appear in openfoam_test under your home directory. To execute the test suite, run:

bash /var/tmp/openfoam_test.sh

Complete installation of AOCC

Because AOCC requires acceptance of a license, we advise a manual step to install AOCC and OpenMPI compiled with AOCC. You can browse to the Cloud Console and use the SSH feature to access the login node. To check if Spack has completed installation, run:

sudo tail -f /var/log/spack.log

You may see a message printed to the screen saying that /home has been remounted and that you should logout and login. Follow its instructions.

Once configuration is complete, install AOCC by running:

sudo bash /var/tmp/install_aocc.sh

Spack will prompt you to accept the AOCC End User License Agreement by opening a text file containing information about the license. Leave the file unmodified and write it to disk by typing :q as two characters in sequence (VI help).

Installation of AOCC and OpenMPI will take approximately 15 minutes.

Configure SSH user keys for access between cluster nodes:

ssh-keygen -N '' -f ~/.ssh/id_rsa
cp ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys
