The MAESTRO project is pleased to announce the availability of the first public release of Maestro Core 0.2, a C library that does multi-threaded cross-application data transfer over high-speed interconnect using lightweight data wrappers that include user metadata.
Maestro Core is part of the Maestro middleware framework, a data- and memory-aware abstraction for workflow coupling, inter- and intra-application data exchange and redistribution. A central design goal was to enable modelling of memory and storage hierarchies to allow for reasoning about data movement and placement based on costs of moving data objects. At the same time, data objects can carry user-defined metadata. This is, e.g., the case for various meteorological production workflows. Leveraging the Maestro middleware allows workflow management software to reason about the data without inspecting it, at scale.
The software is still in an early stage but has been tested in various environments with success, both functionally and performance-wise.
We make the updated Maestro Core available at: https://gitlab.jsc.fz-juelich.de/maestro/maestro-core
