Executive Summary
This deliverable is the output of task 5.2 Understanding the challenges for
distributed computational analysis across Europe. The task activities started
defining a set of aspects for which the project would like to investigate their status
in existing workflow and orchestrator systems. These aspects relate to the
distribution of data and computation, to the support to sensitive data, and to the
support for data provenance and reproducibility. In addition to questions related to
these topics, other generic questions were put all together. An initial classification
of workflow environments and orchestrators was also done, and from there the task
searched for information about the different systems. The information was
provided in some cases by project partners, in other cases by system owners and in
other cases fetched by partners from websites or other sources of information.
From this initial catalogue, the partners involved in this activity selected the most
promising ones that were invited to present in two workshops. The workshops were
online and organized quite informally, but enabled a lot of discussion and provided
in-depth information on the topics more relevant to the project.
The information collected in the two phases of the task (catalogue elaboration and
workshops) is summarized and analysed in this deliverable.
