[Question] How to get platform and device information? #42

I have a device with 2 GPUs:

Intel(R) HD Graphics 520
NVIDIA GeForce 940MX
GPU-Z shows that OpenCL is enabled and is working on both. I get 2 platforms when I obtain platform Ids using JOCL, but I don't know which device is in use! I wonder if I could know how can I get "device name" or its "vendor" using the platform Id?

The https://github.com/gpu/JOCLSamples/blob/master/src/main/java/org/jocl/samples/JOCLDeviceQuery.java sample might be what you're looking for. It iterates through all platforms, and all devices for each platform, and prints the name and vendor of each device (together with lots of further technical information).
