we wonder to know how to set some environment parameters to make GPU_MAX_WORKGROUP_SIZE bigger than 256 and effectively in OpenCL kernel, 256 is the default max value now. we have tried export GPU_MAX_WORKGROUP_SIZE=1024 referenced from [https://github.com/mozkomor/GrinGoldMiner/issues/36], in Nano series card , CentOS release 6.3, OpenCL 1.2, which can be found effectively from clinfo command, but failed in clEnqueueNDRangeKernel with return value= -54.
