IBM releases OpenCL Common Runtime for Linux on x86 architecture

OpenCL™ Common Runtime for Linux® on x86 architecture is an OpenCL layered product that improves the OpenCL programming experience by alleviating the programmer from the burden of managing multiple OpenCL platforms and duplicated resources. It is a dynamic shared library that resides between an OpenCL application and one or more OpenCL implementations, such as those developed by AMD and NVIDIA® .

The Common Runtime supports all of the OpenCL v1.1 APIs in a single OpenCL platform consisting of all devices provided by the underlying implementations. This technology provides an integrated environment that can improve application portability as well as simplifying multi-device programming. The Common Runtime has been tested on the IBM System x® iDataPlex™ dx360 M3 with at least one NVIDIA® Tesla™ M2050 running Red Hat Enterprise Linux 5.5. In addition, OpenCL v1.1 implementations from AMD and NVIDIA were used in conjunction with the OpenCL Common Runtime.
