Two papers accepted at iFM 2019

October 09, 2019

Two papers written by Wytse Oortwijn and Marieke Huisman have been accepted in this year’s edition of iFM.

“Practical Abstractions for Automated Verification of Message Passing Concurrency” presenting a new technique which integrates model based verification and code verification for message passing programs and “Formal Verification of an Industrial Safety-Critical Traffic Tunnel Control System”, a case study in the use of VerCors in a critical industrial system, have been accepted at the 15th International Conference on integrated Formal Methods taking place between the 2nd and the 6th of December this year, at Bergen, Norway.

Blind Henk Mulder now receives a master degree

July 10, 2019

On July 10th, 2019, Henk Mulder got his Master degree at University of Twente.

Henk Mulder did his Master Thesis at the Formal Methods and Tools group, on identifying and solving bottlenecks in the VerCors tool, under the supervision of Marieke Huisman. The VerCors toolset can be used to verify memory safety and functional correctness of concurrent and parallel programs. By encoding the problem into an intermediate language the power of existing tools is leveraged to support additional concurrency models. However, for certain programs verification takes significant time. Thanks to the work of Henk Mulder, we now know why, and more importantly, what we can do about it.

Thesis document

Henk Mulder got a 9 for his Master project, and graduated Cum laude. Our congratulations go out to Henk Mulder, on this great accomplishment!

VERCORS Advisory Board Meeting

June 06, 2019

An advisory board meeting of VerCors was held in University of Twente on June 6, 2019. VerCors Team elaborated main tool features with the board members from different industrial organizations.

The board members include people from BetterBe , Thales group, Rosen group, Polder Valley and Technolution.

The board members have shown a deep interest in the tool and gave valuable feedback to make the VerCors tool more applicable and efficient for industrial projects.

NWO OTP grant for ChEOPS (verified Construction of corrEct and Optimised Parallel Software) Project

May 16, 2019

Prof.dr. Marieke Huisman and dr. Anton Wijs received an NWO OTP grant for the project “ChEOPS: verified Construction of corrEct and Optimised Parallel Software”.

Two PhD students will be appointed, one in Twente and one in Eindhoven, to make the development and maintenance of software aimed at graphics processing units (GPUs) more insightful and effective in terms of functional correctness and performance.

GPUs have an increasingly big impact on industry and academia, due to their great computational capabilities. However, in practice, one usually needs to have expert knowledge on GPU architectures to optimally gain advantage of those capabilities. At the Eindhoven University of Technology, Wijs will work on modelling GPU applications using a Domain Specific Language, formally verifying the correctness of the models, and automatically generating GPU code. At the University of Twente, Huisman will work on the structured optimisation of GPU code, while ensuring that functional correctness is preserved. Existing formal verification techniques, model checking and code verification, will be combined to create, for the first time, a complete end-to-end development workflow for GPU applications.

To ensure the practical effectiveness of the resulting workflow, a users committee, consisting of SURFsara, the Netherlands eScience Center, Stream HPC, and CodePlay (UK), will provide real-life cases and provide feedback throughout the project.
