UPIR generator is a tool based on REX compiler to generate UPIR, a unified parallel intermediate representation that reflects the task and data dependencies as well as other parallelism information.
REX compiler is required. Any other dependencies will be installed while building REX. Please check this guide for REX installation.
Then the environment variable REX_INSTALL must be properly set to indicates the location of REX compiler.
For example, if the REX compiler is installed under /opt/rex_install as follows,
opt
├── rex_install
│ ├── bin
│ ├── include
│ ├── lib
│ └── share
└── ...
To set up the REX compiler for building UPIR generator:
export REX_INSTALL=/opt/rex_install
export LD_LIBRARY_PATH=$REX_INSTALL/lib:$LD_LIBRARY_PATH
export PATH=$REX_INSTALL/bin:$PATH
# set up OpenJDK 1.8
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64/server:$LD_LIBRARY_PATHLLVM is also required to support MLIR. Please follow the instructions here to build LLVM properly.
It could be installed to /opt/llvm-install.
The the opt folder would be like:
opt
├── llvm_install
│ ├── bin
│ ├── examples
│ ├── include
│ ├── lib
│ ├── libexec
│ └── share
├── rex_install
│ ├── bin
│ ├── include
│ ├── lib
│ └── share
└── ...
At the moment, the parallel flow graph and visualation are still work-in-progress. Please ignore them and check UPIR generator in mlir subfolder.
