I missed this when it was published earlier this month. Josh Simons has a post on his blog at Sun about a virtual image that will let you turn your laptop into a virtual cluster using Sun’s technologies
With one free download, you can now turn your laptop into a virtual three-node HPC cluster that can be used to develop and run HPC applications, including MPI apps. We’ve created a pre-configured virtual machine that includes all the components you need:
Sun Studio C, C++, and Fortran compilers with performance analysis, debugging tools, and high-performance math library; Sun HPC ClusterTools — MPI and runtime based on Open MPI; and Sun Grid Engine — Distributed resource management and cloud connectivity
Inside the virtual machine, we use OpenSolaris 2009.06, the latest release of OpenSolaris, to create a virtual cluster using Solaris zones technology and have pre-configured Sun Grid Engine to manage it so you don’t need to. MPI is ready to go as well—we’ve configured everything in advance.
The image is for VMware right now, with VirtualBox in the works. Cool.
