Dynamic resource allocation for efficient parallel CFD simulations
G. Houzeaux, R. M. Badia, R. Borrell +4
CFD users of supercomputers usually resort to rule-of-thumb methods to select the number of subdomains (partitions) when relying on MPI-based parallelization. One common approach i…
Hunting for open clusters in Gaia EDR3: new open clusters found with OCfinder
A. Castro-Ginard, C. Jordi, X. Luri +6
The improvements in the precision of the published data in \textit{Gaia} EDR3 with respect to \textit{Gaia} DR2, particularly for parallaxes and proper motions, offer the opportuni…
A Community Roadmap for Scientific Workflows Research and Development
Rafael Ferreira da Silva, Henri Casanova, Kyle Chard +26
The landscape of workflow systems for scientific applications is notoriously convoluted with hundreds of seemingly equivalent workflow systems, many isolated research claims, and a…
