Generally, this disclosure provides systems, devices, methods and computer readable media for launching MPI-based processes and applications on multiple platform types. A method may include determining a type of an OS associated with a processing node platform on which the MPI-based process is to be launched. The method may also include launching a proxy module on the processing node platform, the proxy module configured to launch the MPI-based process. The launching of the proxy module may include operations that are based on the determination of the OS type of the processing node platform. These operations may include the execution of a secure shell for remote process launching and/or requesting a remote process launching from a system service module executing on the processing node platform.
