If different GPUs share the same buffer, like the code below in "simpleMultiDevice":
for(int i = 0; i < numGPUDevices; i++)
gpu.inputBuffer = inputBuffer;
gpu.outputBuffer = outputBuffer;
In which GPU exactly is the buffer physically located?
If I change the value of the buffer, say gpu.inputBuffer , does it mean the values are changed in each GPU buffer,say gpu.inputBuffer or gpu.inputBuffer or gpu.inputBuffer since they share the same inputBuffer?
Thanks a lot.
