This memory allows in-kernel synchronization commands such as threadfence_system to work transparently. - HIP/ROCm also supports the ability to cache host memory in the GPU using the "Non-Coherent" host memory allocations. This can provide performance benefit, but care must be taken to use the correct synchronization. +## HIP Runtime Compilation +HIP now supports runtime compilation (hipRTC), the usage of which will provide the possibility of optimizations and performance improvement compared with other APIs via regular offline static compilation. + +hipRTC APIs accept HIP source files in character string format as input parameters and create handles of programs by compiling the HIP source files without spawning separate processes. + +For more details on hipRTC APIs, refer to HIP-API.pdf in GitHub (https://github.com/RadeonOpenCompute/ROCm). + +The link here(https://github.com/ROCm-Developer-Tools/HIP/blob/main/tests/src/hiprtc/saxpy.cpp) shows an example how to program HIP application using runtime compilation mechanism. + ## Device-Side Malloc HIP-Clang currently doesn't supports device-side malloc and free.
