Summary: Handling the RPC server requires running through list of jobs that the device has requested to be done. Currently this is handled by the thread that does the waiting for the kernel to finish. However, this is not sound on NVIDIA architectures and only works for async launches in the OpenMP model that uses helper threads. However, we also don't want to have this thread doing work unnnecessarily. For this reason we track the execution of kernels and cause the thread to sleep via a condition variable (usually backed by some kind of futex or other intelligent sleeping mechanism) so that the thread will be idle while no kernels are running.
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
