Distributed Compensations with Interruption in Long-Running Transactions
Universitá di Pisa –
(joint work with Anne Kersten, Ivan Lanese, Giorgio Spagnolo)
Compensations are a well-known and widely used mechanism to ensure the consistency and correctness of long-running transactions in the area of databases.
More recently, several calculi emerged in the area of business process modelling, service-oriented and global computing to provide the necessary formal ground for compensation primitives like those exploited in orchestration languages like WS-BPEL. The focus of this work is on the compensation policy to select for parallel branches. The choice of the right strategy allows the user to prevent unnecessary actions in case of an abort.
In the past different policies have emerged in cCSP and Sagas.
We propose new, optimal, operational and denotational semantics for parallel kernel of cCSP/Sagas with interruption and prove the correspondence between the two. The new semantics guarantees that distributed compensations may only be observed after a fault actually occurred.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
