-# Proactive Data Containers (PDC)
-Proactive Data Containers (PDC) software provides an object-centric API and a runtime system with a set of data object management services. These services allow placing data in the memory and storage hierarchy, performing data movement asynchronously, and providing scalable metadata operations to find data objects. PDC revolutionizes how data is stored and accessed by using object-centric abstractions to represent data that moves in the high-performance computing (HPC) memory and storage subsystems. PDC manages extensive metadata to describe data objects to find desired data efficiently as well as to store information in the data objects.
-
-PDC API, data types, and developer notes are available in docs/readme.md. 
-
-More information and publications of PDC is available at https://sdm.lbl.gov/pdc
-
-# Installation 
-
-The following instructions are for installing PDC on Linux and Cray machines. 
-GCC version 7 or newer and a version of MPI are needed to install PDC. 
-
-Current PDC tests have been verified with MPICH. To install MPICH, follow the documentation in https://www.mpich.org/static/downloads/3.4.1/mpich-3.4.1-installguide.pdf
-
-PDC also depends on libfabric and Mercury. We provide detailed instructions for installing libfabric, Mercury, and PDC below.
-Make sure to record the environmental variables (lines that contains the "export" commands). They are needed for running PDC and to use the libraries again.
-
-## Preparing for Installation
-
-PDC relies on [`libfabric`](https://github.com/ofiwg/libfabric/) as well as [`mercury`](https://github.com/mercury-hpc/mercury). Therefore, let's **prepare the dependencies**.
-### Preparing Work Space
-
-Before installing the dependencies and downloading the code repository, we assume there is a directory created for your installation already, e.g. `$WORK_SPACE` and now you are in `$WORK_SPACE`.
-
-```bash
-export WORK_SPACE=/path/to/your/work/space
-mkdir -p $WORK_SPACE/source
-mkdir -p $WORK_SPACE/install
-```
-
-### Download Necessary Source Repository
-
-Now, let's download [`libfabric`](https://github.com/ofiwg/libfabric/), [`mercury`](https://github.com/mercury-hpc/mercury) and [`pdc`](https://github.com/hpc-io/pdc/tree/develop) into our `source` directory.
-
-```bash
-cd $WORK_SPACE/source
-git clone git@github.com:ofiwg/libfabric.git
-git clone git@github.com:mercury-hpc/mercury.git
-git clone git@github.com:hpc-io/pdc.git
-```
-
-### Prepare Directories for Artifact Installation
-```bash
-export LIBFABRIC_SRC_DIR=$WORK_SPACE/source/libfabric
-export MERCURY_SRC_DIR=$WORK_SPACE/source/mercury
-export PDC_SRC_DIR=$WORK_SPACE/source/pdc
-
-export LIBFABRIC_DIR=$WORK_SPACE/install/libfabric
-export MERCURY_DIR=$WORK_SPACE/install/mercury
-export PDC_DIR=$WORK_SPACE/install/pdc
-
-mkdir -p $LIBFABRIC_SRC_DIR
-mkdir -p $MERCURY_SRC_DIR
-mkdir -p $PDC_SRC_DIR
-
-mkdir -p $LIBFABRIC_DIR
-mkdir -p $MERCURY_DIR
-mkdir -p $PDC_DIR
-
-echo "export LIBFABRIC_SRC_DIR=$LIBFABRIC_SRC_DIR" > $WORK_SPACE/pdc_env.sh
-echo "export MERCURY_SRC_DIR=$MERCURY_SRC_DIR" >> $WORK_SPACE/pdc_env.sh
-echo "export PDC_SRC_DIR=$PDC_SRC_DIR" >> $WORK_SPACE/pdc_env.sh
-
-echo "export LIBFABRIC_DIR=$LIBFABRIC_DIR" >> $WORK_SPACE/pdc_env.sh
-echo "export MERCURY_DIR=$MERCURY_DIR" >> $WORK_SPACE/pdc_env.sh
-echo "export PDC_DIR=$PDC_DIR" >> $WORK_SPACE/pdc_env.sh
-```
-
-Remember, from now on, at any time, you can simply run the following to set the above environment variables so that you can run any of the following command for your installation.
-
-```bash
-export WORK_SPACE=/path/to/your/work/space
-source $WORK_SPACE/pdc_env.sh
-```
-
-### Compile and Install`libfabric`
-
-Check out tag `v1.11.2` for `libfabric`:
-
-```bash
-cd $LIBFABRIC_SRC_DIR
-git checkout tags/v1.11.2
-```
-
-Configure, compile and install:
-
-```bash
-./autogen.sh
-./configure --prefix=$LIBFABRIC_DIR CC=cc CFLAG="-O2"
-
-make -j 32
-make install
-
-export LD_LIBRARY_PATH="$LIBFABRIC_DIR/lib:$LD_LIBRARY_PATH"
-export PATH="$LIBFABRIC_DIR/include:$LIBFABRIC_DIR/lib:$PATH"
-
-echo 'export LD_LIBRARY_PATH=$LIBFABRIC_DIR/lib:$LD_LIBRARY_PATH' >> $WORK_SPACE/pdc_env.sh
-echo 'export PATH=$LIBFABRIC_DIR/include:$LIBFABRIC_DIR/lib:$PATH' >> $WORK_SPACE/pdc_env.sh
-```
-
-Note: On NERSC supercomputers, e.g. Cori and Perlmutter, we should add `--disable-efa --disable-sockets` to the `./configure` command during the compilation on login nodes.
-
-### Compile and Install `mercury`
-
-Now, you may check out a specific tag version of `mercury`, for example, `v2.2.0`:
-
-```bash
-cd $MERCURY_SRC_DIR
-mkdir build
-git checkout tags/v2.2.0
-git submodule update --init
-```
-
-Configure, compile, test and install:
-
-```bash
-cd build
-cmake ../ -DCMAKE_INSTALL_PREFIX=$MERCURY_DIR -DCMAKE_C_COMPILER=cc -DBUILD_SHARED_LIBS=ON -DBUILD_TESTING=ON -DNA_USE_OFI=ON -DNA_USE_SM=OFF -DNA_OFI_TESTING_PROTOCOL=tcp 
-make -j 32 && make install
-
-ctest
-
-export LD_LIBRARY_PATH="$MERCURY_DIR/lib:$LD_LIBRARY_PATH"
-export PATH="$MERCURY_DIR/include:$MERCURY_DIR/lib:$PATH"
-
-echo 'export LD_LIBRARY_PATH=$MERCURY_DIR/lib:$LD_LIBRARY_PATH' >> $WORK_SPACE/pdc_env.sh
-echo 'export PATH=$MERCURY_DIR/include:$MERCURY_DIR/lib:$PATH' >> $WORK_SPACE/pdc_env.sh
-```
-
-## Compile and Install PDC
-Now, it's time to compile and install PDC.
-
-* One can replace `mpicc` to other available MPI compilers. For example, on Cori, `cc` can be used to replace `mpicc`. 
-* `ctest` contains both sequential and MPI tests for the PDC settings. These can be used to perform regression tests.
-
-```bash
-cd $PDC_SRC_DIR
-git checkout develop
-mkdir build
-cd build
-cmake ../ -DBUILD_MPI_TESTING=ON -DBUILD_SHARED_LIBS=ON -DBUILD_TESTING=ON -DCMAKE_INSTALL_PREFIX=$PDC_DIR -DPDC_ENABLE_MPI=ON -DMERCURY_DIR=$MERCURY_DIR -DCMAKE_C_COMPILER=cc -DMPI_RUN_CMD=srun 
-make -j 32 && make install
-```
-
-Let's run `ctest` now on a compute node:
-
-### On Cori
-```bash
-salloc --nodes 1 --qos interactive --time 01:00:00 --constraint haswell
-```
-### On Perlmutter
-
-```bash
-salloc --nodes 1 --qos interactive --time 01:00:00 --constraint cpu --account=mxxxx
-```
-
-Once you are on the compute node, you can run `ctest`.
-
-```bash
-ctest
-```
-
-Note: On Cori, if you happen to see failures regarding `libibverb` validation, login to one of the compute nodes by running an interactive job and re-compile all PDC's dependencies and PDC itself. Then problem will be solved.
-
-If all the tests pass, you can now specify the environment variables.
-
-```bash
-export LD_LIBRARY_PATH="$PDC_DIR/lib:$LD_LIBRARY_PATH"
-export PATH="$PDC_DIR/include:$PDC_DIR/lib:$PATH"
-
-echo 'export LD_LIBRARY_PATH=$PDC_DIR/lib:$LD_LIBRARY_PATH' >> $WORK_SPACE/pdc_env.sh
-echo 'export PATH=$PDC_DIR/include:$PDC_DIR/lib:$PATH' >> $WORK_SPACE/pdc_env.sh
-```
-
-## About Spack
-
-One can also install `PDC` with [`Spack`](https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/pdc/package.py), with which the dependencies of `PDC` can be easily managed and installed.
-
-```bash
-git clone -c feature.manyFiles=true https://github.com/spack/spack.git
-cd spack/bin
-./spack install pdc
-```
-
-## Running PDC
-
-Essentially, PDC is a typical client-server application.
-To run `PDC`, one needs to start the server processes first, and then the clients can be started to issue RPC requests handled by the `Mercury` RPC framework. 
-
-We provide [`mpi_test.sh` utility](https://github.com/hpc-io/pdc/blob/develop/examples/mpi_test.sh) for running MPI tests. For example, on a regular Linux machine, you may run the following:
-
-```bash
-export JOB_RUNNER=mpiexec
-cd $PDC_DIR/bin
-./mpi_test.sh ./pdc_init $JOB_RUNNER 2 4
-```
-
-This is test will start 2 processes for PDC servers. The client program ./pdc_init will start 4 processes. Similarly, one can run any of the client examples in `ctest`.
-
-Depending on the specific HPC environment where you run `PDC` , the value of `$JOB_RUNNER` variable can be changed to `srun` (for NERSC), `aprun` (for Theta), or `jsrun` for `Summit`, accordingly.
-
-These source code will provide some knowledge of how to use PDC. For more reference, one may check the documentation folder in this repository.
-
-# PDC on Cori
-
-If you are running `PDC` on Cori supercomputer, here are some tips you would need to follow:
-
-* On Cori, it is recommended to use `cc` as the default compiler when compiling PDC and its dependencies. 
-* When preparing compilation for `PDC` using `CMake`, it is suggested to append console argument `-DMPI_RUN_CMD=srun` so that `ctest` can be executed on Cori.
-* Sometimes, it might be helpful to unload `darshan` module before the installation. 
-
-* For opening an interactive job session on Cori, it is recommended to add `--gres=craynetwork:2` option to the `salloc` command:
-    ```bash
-    salloc -C haswell -N 4 -t 01:00:00 -q interactive --gres=craynetwork:2
-    ```
-* To launch the PDC server and the client, add `--gres=craynetwork:1` before the executables, for example:
-
-  * Run 4 server processes, each on one node in background:
-    ```bash
-    srun -N 4 -n  4 -c 2 --mem=25600 --cpu_bind=cores --gres=craynetwork:1 --overlap ./bin/pdc_server.exe &
-    ```
-
-  * Run 64 client processes that concurrently create 1000 objects in total:
-    ```bash
-    srun -N 4 -n 64 -c 2 --mem=25600 --cpu_bind=cores --gres=craynetwork:1 --overlap ./bin/create_obj_scale -r 1000
-    ```
