States how many GPUs and what percent of each a test requires.
rapids_test_gpu_requirements( test_name GPUS <N> [PERCENT <value>])
This function should only be used when
insufficient due to the rapids-cmake test wrappers not working for your
When combined with
rapids_test_init() informs CTest what
resources should be allocated to a test so that when testing in parallel
oversubscription doesn’t occur. Without this information user execution of
CTest with high parallel levels will cause multiple tests to run on the
same GPU and quickly exhaust all memory.
State how many GPUs this test requires. Allows CTest to not over-subscribe a machine’s hardware.
Any integer value >= 0 is supported
State how much of each GPU this test requires. In general 100, 50, and 20 are commonly used values. By default if no percent is provided, 100 is used.
Any integer value >= 0 and <= 100 is supported
Default value of 100
