Agent View

The status for a particular CPU Agent can be viewed by selecting the CPU host name in the tree.

This window has selection tabs at the top, with the default tab selecting "Agent/CUDA" status. The "Agent/CUDA" tab displays hardware and software environmental information for the CPU, followed by a list of CUDA-capable devices available to the CPU.

Bandwidth Test

A test of the PCI Express link to each GPU can be initiated by pressing the "Bandwidth Test" button. This test allocates and transfers blocks of memory from CPU to GPU in order to exercise the PCI Express link, and also to provide a measure of the actual throughput in MegaBytes/second. The test walks through the list of GPUs one at a time, and continues to run until the "Bandwidth Test" button is pressed a second time.

Stress Test

A test of the PCI Express links to all GPUs can be initiated by pressing the "Stress Test" button. Similar to the Bandwidth Test, this test allocates and transfers blocks of memory from CPU to GPU. The stress test maintains a continuous load on all GPUs, and continues to run until the "Stress Test" button is pressed a second time.
