HOW TO USE CODEQUERY WITH C/C++ CODE?

Change directory to the base folder of your source code like this:

cd ~/projects/myproject/src

Create a cscope.files file with all the C/C++ source files listed in it. Files with inline assembly code should be excluded from this list.

find . -iname "*.c"    > ./cscope.files
find . -iname "*.cpp" >> ./cscope.files
find . -iname "*.cxx" >> ./cscope.files
find . -iname "*.cc " >> ./cscope.files
find . -iname "*.h"   >> ./cscope.files
find . -iname "*.hpp" >> ./cscope.files
find . -iname "*.hxx" >> ./cscope.files
find . -iname "*.hh " >> ./cscope.files

Create a cscope database like this (add k, if you don’t want standard include paths like for stdio.h):

cscope -cb

Create a ctags database like this.

ctags --fields=+i -n -L ./cscope.files

Run cqmakedb to create a CodeQuery database out of the cscope and ctags databases, like this:

cqmakedb -s ./myproject.db -c ./cscope.out -t ./tags -p

Open myproject.db using the CodeQuery GUI tool by running the following. Wild card search (* and ?) supported if Exact Match is switched off. Or use cqsearch, the CLI-version of CodeQuery (type cqsearch -h for more info).

codequery

Use cqmakedb -h to get help on cqmakedb command line arguments.

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

4 minute read

Published:

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

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.
