8 years ago Hi Matt, please try setting env var HIP_PLATFORM to "hcc" so hip will recognize the nanos.

I was able to do the tutorial on gpuopen.comhttp://gpuopen.com but found that hipGetDeviceCount was only returning 1 so the examples would only run on my primary GPU a GTX 980Ti. I also have an R9 Nano and an R9 Fury. The kfd driver exports 3 nodes under topology so the runtime should let me talk to them. I'm running Ubuntu 15. I was hoping to instrument hip_hcc.cpp to see what it was doing right here:
/*
- Build a table of valid compute devices. */ auto accs = hc::accelerator::get_all(); int deviceCnt = 0; for (int i=0; i<accs.size(); i++) { if (! accs[i].get_is_emulated()) { deviceCnt++; } };
- printf("actual device count is %d\n", deviceCnt); // Make sure the hip visible devices are within the deviceCnt range for (int i = 0; i < g_hip_visible_devices.size(); i++) { if(g_hip_visible_devices[i] >= deviceCnt){ // Make sure any DeviceID after invalid DeviceID will be erased. g_hip_visible_devices.resize(i); break; } }
But I can't even get it to compile: ~/devel/HIP2$ make ./bin/hipcc -I/opt/hcc/include -std=c++11 -I/opt/hsa/include src/hip_hcc.cpp -c -O3 -o src/hip_hcc.o src/hip_hcc.cpp:52:2: error: #error (USE_AM_TRACKER requries HCC version of 16074 or newer)

I made the following change to the Makefile in response to complaints. But it's still not doing anything. And it looks like it's trying to compile the code with nvcc: mmacy@pandemonium:~/devel/HIP2$ hipcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2015 NVIDIA Corporation Built on Tue_Aug_11_14:27:32_CDT_2015 Cuda compilation tools, release 7.5, V7.5.17
