Someone just pointed out that Mozilla Firefox treats GPUs differently when it uses WebGL:

This got me thinking how little I know about GPU security. 😦

There’s a bit on GPU security in the August Intel security report:

I noticed the tool Cryptohaze, but it appears to have not been updated since 2013 or so:

“Cryptohaze is the home of high performance, open source, network-enabled, US-based cross-platform GPU and OpenCL accelerated password auditing tools for security professionals. The tools run on all platforms that support CUDA or OpenCL (currently Windows, Linux, OS X). If you don’t have a GPU – the OpenCL code will run just fine on your host CPU!”

If you know of other useful GPU security tools, please speak up!
