Aqua Vanjaram is intended to have fine-grained coherency from anywhere to anywhere else using read-acquire and write-release primitives. Add a test that writes to memory covered by five different cache lines, then write-releases, while another thread read-acquires, then reads those five locations in memory. There are nine variations of the test to cover CPU-GPU, same-GPU and across-GPU, vector instructions and scalar instructions, and data local to the acquirer or receiver.

1. Note on building kfdtest To build this kfdtest application, the following libraries should be already installed on the building machine: libdrm libdrm_amdgpu libhsakmt If libhsakmt is not installed, but the headers and libraries are present locally, you can specify its directory by export LIBHSAKMT_PATH=/*your local libhsakmt folder*/ With that, the headers and libraries are searched under LIBHSAKMT_PATH/include and LIBHSAKMT_PATH/lib respectively. 2. How to run kfdtest Just run "./run_kfdtest.sh" under the building output folder. You may need to specify library path through: export LD_LIBRARY_PATH=/*your library path containing libhsakmt*/ Note: you can use "run_kfdtest.sh -h" to see more options.
