Build LLVM on Windows

less than 1 minute read

To build LLVM on Windows, Cmake and Vistual Studio is required.

Take a look at this page for the complete manual.

Grab LLVM source and checkout to a desired tag/branch:

git clone --config core.autocrlf=false https://github.com/llvm/llvm-project.git

cd llvm-project

# Checkout to a tag, for instance:
git checkout llvmorg-17.0.1

In the root directory of the repo (not build), run cmake with desired options:

cmake -B build -G "Visual Studio 16 2019" -DLLVM_ENABLE_PROJECTS='clang;clang-tools-extra;lld;lldb' \
 -DCMAKE_BUILD_TYPE=Release -DLLVM_PARALLEL_COMPILE_JOBS=4 -DLLVM_PARALLEL_LINK_JOBS=4 \
 -DLLVM_ENABLE_RUNTIME='compiler-rt;libc;libcxx;openmp' -S llvm

This command will create LLVM.sln file. Open it in Visual Studio, change the build type to Release and build the whole project.

After completion, the binary files should be under build/Release/bin.

Utilize PTX Just-In-Time (JIT) Compilation in CUDA

4 minute read

In this post I’ve written about how to utilize PTX Just-In-Time (JIT) compilation in CUDA. PTX is a low-level assembly-like language that is used to represent the GPU code. The PTX code is then compiled to the machine code by the NVIDIA driver at runtime. This process is called Just-In-Time (JIT) compilation. But before I write about how to use PTX JIT compilation, I’ll provide some background on why you might want to use it.

This is a collection of my dotfiles that I use on my Linux system. I have written about them in various posts, but I thought I can put them all in one place. You can checkout the github repository here, too.

Setup LAMMPS

Published:

Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is a classical molecular dynamics code that can be used to model atoms or, more generally, as a parallel particle simulator at various scales. The complete documentation of LAMMPS can be found here. In this post, I will provide a guide on how to setup LAMMPS on a Linux machine. My setup is on a cluster with NVIDIA GPUs, UCX, and OpenMPI. Also, we have a built-in module system to load the necessary modules.
