A Mac OS X implementation is also in the works. The problem the developers are trying to highlight lies not with the operating systems, such as Windows or Linux, nor with the GPU (graphics processor unit) vendors, but rather with existing security tools, which aren't designed to scan the random access memory used by GPUs for malware code.
