Azure MS-MPI in a Box
Blog post from Rescale
A self-contained Cloud Service package has been released to simplify setting up an InfiniBand Microsoft MPI cluster on Azure PaaS without requiring the full HPC Pack installation, addressing the challenges mentioned in previous discussions. This "MPI-in-a-box" solution allows users to deploy clusters for temporary tasks by downloading and deploying a pre-built package and adjusting a few settings in a configuration file. The package includes a startup script that installs Microsoft MPI, configures firewall ports, creates a machinefile for mpiexec calls, and installs a Cygwin OpenSSH server for remote access. Users must specify key settings in the configuration file, such as the number of instances and SSH public keys for admin and job users. Once configured, the service can be deployed through the Azure Management web page or API, enabling SSH connectivity to role instances via specified ports. The script also sets up an SMB file share for file distribution among nodes, though using azcopy for input file downloads may improve performance. The Cloud Service's source code is available on GitHub for further development and contribution.
