Bridging the design and implementation of distributed systems with program analysis.
University of British Columbia –
Much of today’s software runs in a distributed context: mobile apps
communicate with the cloud, web apps interface with complex
distributed backends, and cloud-based systems use geo-distribution and
replication for performance, scalability, and fault tolerance.
However, distributed systems that power most of today’s infrastructure
pose unique challenges for software developers. For example, reasoning
about concurrent activities of system nodes and even understanding the
system’s communication topology can be difficult.
In this talk I will overview three program analysis techniques developed in
my group that address these challenges. First, I will present Dinv, a
dynamic analysis technique for inferring likely distributed state
properties of distributed systems. By relating state across nodes in the
system Dinv infers properties that help reason about system correctness.
Second, I will review Dara, a model checker for distributed systems that
introduces new techniques to cope with state explosion by combining
traditional abstract model checking with dynamic model inference
techniques. Finally, I will discuss PGo, a compiler that compiles formal
specifications written in PlusCal/TLA+ into runnable distributed system
implementations in the Go language. All three projects employ program
analysis in the context of distributed systems and aim to bridge the gap
between the design and implementations of such systems.

Mathematics, Physics & Machine Learning Seminar Series (Online)
The Mathematics, Physics & Machine Learning seminar series has started on October 2020 and runs until March 2021.
The seminars aim to bring together mathematicians and physicists interested in machine learning (ML) with ML and AI experts interested in mathematics and physics, with the goal of introducing innovative Mathematics and Physics-inspired techniques in Machine Learning and, reciprocally, applying Machine Learning to problems in Mathematics and Physics.
Attendance is free but registration is required.

International European Conference on Parallel and Distributed Computing
The 27th International European Conference on Parallel and Distributed Computing (Euro-Par 2021) will take from August 30 to September 3 2021 in Lisbon.
Euro-Par is the prime European conference covering all aspects of parallel and distributed processing, ranging from theory to practice, from small to the largest parallel and distributed systems and infrastructures, from fundamental computational problems to full-fledged applications, from architecture, compiler, language and interface design and implementation, to tools, support infrastructures, and application performance aspects.
The 2021 edition of Euro-Par will be organized as a collaboration between INESC-ID and Instituto Superior Técnico (IST).
