// Test Description:
/*The general idea of the application is to test how Cooperative Groups kernel
launches work when launching too many warps to the target device. This test
first queries the nominal warp size of the target device. It then walks through
block sizes from 1 thread, 1 warp, 2 warps, ... `maximum_warps_in_a_block`. For
each of these, it queries the maximum number of blocks that can fit in each SM.
It then queries the number of SMs on the target device. This will yield a
calculation for the maximum number of blocks that can be co-scheduled on this
device.
The Cooperative Groups API says that users should not launch more than this
many warps (or blocks, etc.) to the target device. This test first tires to
launch 2x as many blcoks, to confirm that the runtime prevents such a launch
by returning a proper error value (`hipErrorCooperativeLaunchTooLarge`).
It then ensures that trying to launch too large of a kernel invocation does
not break the GPU by launching a kernel with exactly the maximum number of
blocks.
Finally, we run the same test for a block size that is larger than the maximum
allowed by the device, to ensure that this case is properly detected by the
runtime and that nothing breaks.*/
