In some cases, this might be due to an invalid global work size, but it can also be due to several compilation errors. If you think that this is a bug in ViennaCL, please report it at viennacl-support@lists.sourceforge.net and supply at least the following information: * Operating System * Which OpenCL implementation (AMD, NVIDIA, etc.) * ViennaCL version Many thanks in advance! Hope this helps, Michael
