I’m wondering if the visual profiler work with multiple devices?

It works with multiple devices on one host, however I haven’t tried it with multiple devices in one application.

Good question! I just tried it out. The profiler seems to do funny things with multi-GPU applications.

At first glance, the output in the profile log seems to be from just 1 of the 2 GPUs I ran on. But the visual profiler refuses to read in the resulting profile log, complaining about missing columns in random spots.
