SUMMARY:Sirocco: Streamlining Reproducible High Resolution Climate Workflo
 ws
DESCRIPTION:Matthieu Leclair (ETH Zurich), Alexander Goscinski (PSI), Rico
  Häuselmann (ETH Zurich / CSCS), and Julian Geiger (PSI)\n\nWith the incre
 ase in simulation resolution, climate and weather models are now potential
 ly outputting petabytes of data so that the largest projects now require c
 omplex workflows tightly integrating preprocessing, postprocessing, potent
 ial downstream applications and archiving. We present here Sirocco, a clim
 ate and weather workflow tool currently under development written in pytho
 n in collaboration between ETHZ, CSCS and PSI. It builds on top of the low
 -level generic workflow tool library AiiDA and the AiiDA-workgraph layer. 
 Sirocco defines a user-friendly yaml based configuration format describing
  the workflow graph in which, equally to tasks, data nodes\nnaturally beco
 me first class citizens by using AiiDA objects. The graph is first generat
 ed as an internal representation, then translated to an aiida-workgraph ob
 ject and finally orchestrated by AiiDA. Sitting on top of AiiDA, Sirocco c
 an naturally target different HPC systems. Still the current effort focuse
 s on the Alps system and the ICON model with the aim of not only making co
 mplex workflows possible but also make the ICON users life overall easier 
 on Alps by integrating specifics of ICON and the advanced HPC management o
 f Alps involving technologies like user environments and FirecREST.\n\nDom
