The Damaris library is being used within the ACROSS project to improve the I/O performance of one of the three pilot use cases being used in a software-hardware co-design methodology.
The pilot use-case is the OPM flow software which is an open-source code for simulating sub-surface geological flows of mixtures of fluids. The code is being developed to model carbon dioxide capture and storage options over long time scales. The simulations will be computationally demanding and improved I/O will help the performance of the code. The ACROSS project is also supporting the extension of Damaris for in-situ analytics, where embedding Python in conjunction with other distributed analytic libraries (e.g. MELISSA, Ray) is being trialed as a way to query and analyze results of simulations while minimizing the required amount of output data being needed for post-processing. Of course, this will be able to be done asynchronously, with minimal effect on the simulation runtime with the help of Damaris.

Version v1.9.1 of Damaris is a maintenance release This release adds extra checks for scripts existence from the Paraview and Python XML elements. Python scripts are also now only checked and read by a single server rank and broadcast to other server ranks. Better logging support for flushing the log…
Version v1.9.0 of Damaris is a feature release for added support of Unstructured Mesh mesh types in the Paraview Catalyst in situ visualization. This release has added support for polygonal and polyhedral unstructured mesh cell types in the Paraview Damaris server component and also added support for separate x,y and…
Version v1.8.2 of Damaris is a bugfix/enhancement for the build system when being configured by another project for use via CMake This release modified the DamarisConfig.cmake.in configuration to search for Boost::python and Boost::numpy when ENABLE_PYTHON=ON is specified in the Damaris build. It is a fixe for issue 29 Download is…
Version v1.8.1 of Damaris is a bugfix for the new select HDF5 code and addition of a number of new examples that are discussed in the Damaris wiki The Damaris wiki site is available here: Damaris-HDF5-Select-Points-Support Download is available from the Damaris download page.
Version v1.8.0 of Damaris adds various changes to the library. Notably New client code API calls damaris_get_type() and damaris_error_string() HDF5 point selection code Added classes for describing unstructured mesh data and sharing with Damaris Damaris XML variable comments are written as HDF5 attributes of the dataset written Bugfix for HDF5…
Version v1.7.0 of Damaris adds support for asynchronous Python based processing. This Damaris server side plug-in has support for Dask which is a Python distributed runtime engine and opens up a large number of analytic methods that can use Dask data types, these include SciKit-Learn and Tensorflow/Keras. In the Damaris…
This version of Damaris adds a ModifyModel class that enables the XML configuration file to be constructed and saved to programmatically, within C++ source code. Please see the following page for more information in-line-creation-of-damaris-xml-configuration-file. The release also includes logging of the time it takes for Damaris server cores to complete…
As part of a PRACE 6IP project, a report on the use of Damaris for improved I/O and in-situ visualization has been published on the PRACE website, entitled “In-situ visualization using Damaris: The Code_Saturne use case” The report documents the results of instrumenting Code_Saturne, an open-source Computational Fluid Dynamics (CFD)…
Damaris 1.5.0 has been released. This version adds support for the unstructured mesh data layout type, and currently the implementation only has ParaView support (VisIt support is on the way). It also includes better logging support and bug fixes included. Download is available from the Damaris download page. (N.B. There…
