Different GPU cards have different limits of how much memory you can 
allocate in a single block. If I recall correctly nVidia reports a lower 
max block size to OpenCL than to cuda, for Fermi devices.

The max block size (or some similarly named property) is reported by any 
standard GPGPU card property reporting tool (e.g. oclDeviceQuery)
