VirtualCL (VCL) cluster platform is a wrapper for OpenCL™ that allows most unmodified applications to transparently utilize multiple OpenCL devices in a cluster as if all the devices are local. Main features     Works with OpenCL devices from all vendors. Supports almost all OpenCL 1.1 (and 1.0) applications. Applications can use cluster-wide OpenCL devices. Transparent selection of devices. Supports multiple applications on the same cluster. Applications can be started on any hosting-computer, including computers without OpenCL devices. Supports SuperCL, an extension of OpenCL that allows micro-programs to run efficiently on devices of remote nodes. Runs on Linux clusters, with or without MOSIX. VCL support for SLURM       Provides a per-job private ad-hoc VCL cluster, based on SLURM's allocation rather than having a fixed cluster. This includes the necessary SLURM prologs and epilogs to establish and destroy this private cluster. Informs SLURM when VCL detects insufficient OpenCL devices. Includes instructions for SLURM administrators and users on how to incorporate VCL into SLURM. VCL support for MPI and multitasking     A pre-allocation option, to prevent improper competition for devices between ranks. An option to ban unwanted devices, making them invisible to the application. Further information is available in the VCL White paper, Guides and Manuals, Presentation, Changelog and FAQ.
