on monday I updatet our Cluster Studio to the latest version and did some update for Ubuntu with apt-get upgrade. Since then the OpenCL isn't working any more (2xIntel Xeon 2670 and Xeon Phi coprocessor). If I call clGetPlatformIDs I get the -1001 error pack and the platformcount variable is set to 0. Then I uninstalled OpenCL completely and installed the latest files. But no change. Same problem with gcc. I did the installation in the same way as described here:
