It initially proposed to dedicate cores for asynchronous I/O in multicore nodes of recent HPC platforms, with an emphasis on ease of integration in existing simulation, efficient resource usage (with the use of shared memory) and simplicity of extension through plugins.

Damaris is being developed by the KerData team at INRIA Rennes, within the framework of the Joint Laboratory for Extreme Scale Computing (JLESC), a collaboration between INRIA, the University of Illinois at Urbana Champaign, Argonne National Laboratory and Barcelona Supercomputing Center, and the Data@Exascale associated team between KerData, ANL and UIUC.
