AXL: Asynchronous Transfer Library

The Asynchronous Transfer Library provides a common C interface to transfer files between layers in an HPC storage hierarchy.

For details on its usage, see doc/README.md. For API details, see AXL User API docs.

Quickstart

AXL uses the CMake build system and we recommend out-of-source builds.

git clone https://github.com/ECP-VeloC/AXL.git
mkdir build
mkdir install

cd build
cmake -DCMAKE_INSTALL_PREFIX=../install ../AXL
make
make install
make test

Some useful CMake command line options:

• -DCMAKE_INSTALL_PREFIX=[path]: Place to install the AXL library
• -DCMAKE_BUILD_TYPE=[Debug/Release]: Build with debugging or optimizations

For building with IBM BB API (optional):

• -DAXL_ASYNC_API=IBM_BBAPI: Enable IBM BB API
• -DWITH_BBAPI_PREFIX=/opt/ibm/bb: Install path to IBM BB library

Dependencies

• C
• CMake, Version 2.8+
• KVTree
