My friend Cydney brought me to the AMD booth and introduced me to Scot Schultz, pictured here. He was showing a nice demo of an N-body simulation written in OpenCL running in a Linux VM on vSphere 5. The GPU was made visible to the VM using VMware Direct Path I/O in the same manner we used internally for running CUDA tests on both AMD and nVidia GPUs. As reported here , we achieved close to 98% of native performance for most tests we tried. It was excellent to see AMD showing off the ability to achieve high compute performance with GPUs in a virtual environment!
