A parallel framework and tool library. It includes the following components:

• wiki app: provide interfaces for developing parallel applications and built-in MPI wrapper.
• I/O: high level parallel I/O API based on MPI-I/O.
• logs: fmt-based parallel log component. It is designed for parallel applications, which can output MPI rank id and provide configurable log destination (e.g. log to console or to file).
• bundle: pack data to a bytes buffer and unpack data from the buffer. It supports the config component.
• config: provide a mechanism for: packing data to a bytes buffer and BCast to all processors; unpacking and recovering the origin data after BCast.
• event: a listener to receive and process MPI messages.

see directory docs.

1. install dependency

$ cd kiwi
$ pkg fetch
$ pkg install # install fmt lib, google test lib(for linking test) and some header files.

2. build mpi lib is required for building kiwi lib.

$ cmake -B./build/ -H./
$ cmake --build ./build -j 4
$ make install # only kiwi lib is installed, fmt lib and mpi lib should be linked in your program.
