| - | The task is to write one or more OpenCL kernels using the convenience wrappers provided by ViennaCL to find the character with highest ASCII code in a sequence ('vector<char>' in ViennaCL) of characters. For example, the character with highest ASCII code in “ABRACADRABRA” is 'R'. Come up with a good, fast and correct algorithm by extending the [[https://github.com/viennacl/viennacl-dev/blob/master/examples/tutorial/custom-kernels.cpp|Custom OpenCL kernels example]] provided with ViennaCL. | + | The task is to write one or more OpenCL kernels using the convenience wrappers provided by ViennaCL to find the character with highest ASCII code in a sequence ('vector<char>' in ViennaCL. **UPDATE Apr 6, 2015: Unfortunately there is a bug in the current ViennaCL which prohibits the use of vector<char>.
