WebOct 31, 2012 · In CUDA, the host refers to the CPU and its memory, while the device refers to the GPU and its memory. Code run on the host can manage memory on both the host and device, and also launches kernels which are functions executed on the device. These kernels are executed by many GPU threads in parallel. WebThe 11.2 CUDA C++ compiler can optionally generate a function-inlining diagnostic report for device functions that can provide insights into the compiler’s function inlining decisions. These diagnostic reports can aid advanced CUDA developers in application performance analysis and tuning efforts.
