This software is business-critical as defects in this software have major impacts on revenue and customer satisfaction. The primary means for verification of this software is testing. We conducted an extensive analysis of Java software packages to evaluate their unit-testability. The results show that code in software repositories is typically split into portions of very trivial code, nontrivial code that is unit-testable, and code that cannot be unit-tested easily. This brings up interesting considerations regarding the use of test coverage metrics and design for testability, which is crucial for testing efficiency and effectiveness. Lack of unit-testability is an obstacle to applying tools that perform automated verification and test generation. These tools cannot make up for poor testability of the code and have a hard time in succeeding or are not even applicable without first improving the design of the software system.","PeriodicalId":6479,"journal":{"name":"2016 Formal Methods in Computer-Aided Design (FMCAD)","volume":"33 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81273471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One option for such storage is a hash map and this has been used in many model checkers. In particular, we are interested in the performance of concurrent hash maps for use in multi-core model checkers with a variable state vector size. Previous research claimed that open addressing was the best performing method for the parallel speedup of concurrent hash maps. However, here we demonstrate that chaining lends itself perfectly for use in a concurrent setting.We implemented 12 hash map variants, all aiming at multicore efficiency. 8 of our implementations support variable-length key-value pairs. We compare our implementations and 22 other hash maps by means of an extensive test suite. Of these 34 hash maps, we show the representative performance of 11 hash maps. Our implementations not only support state vectors of variable length, but also feature superior scalability compared with competing hash maps. Our benchmarks show that on 96 cores, our best hash map is between 1.3 and 2.6 times faster than competing hash maps, for a load factor under 1. For higher load factors, it is an order of magnitude faster.","PeriodicalId":6479,"journal":{"name":"2016 Formal Methods in Computer-Aided Design (FMCAD)","volume":"1 1","pages":"46-54"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75782805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the emergence of autonomous systems in our every day lives, we need to design algorithms and tools that enable safe and seamless interactions with people.In this talk, I will start with my journey in providing safety for human-robot systems by discussing a spectrum of views on safe autonomous systems including a formal methods perspective for synthesizing provably correct controllers, a robust control approach, and more recent advances in safe learning and verification. I will then discuss one of the main challenges of safety of human-robot systems, i.e., studying how robots influence humans actions in one-on-one or group settings. This is usually overlooked by assuming humans act as external disturbances just like moving obstacles, or assuming that automation can always help societies without actually considering how humans can be impacted. I will talk about our recent work in building computational models of human behavior from expert demonstrations and preferences in interaction with autonomous systems and challenges it introduces for safety and robustness verification.","PeriodicalId":6479,"journal":{"name":"2016 Formal Methods in Computer-Aided Design (FMCAD)","volume":"83 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87250674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For unsatisfiable queries, a reasonable approach is to have the solver return an independently checkable proof of unsatisfiability. We propose a lazy, extensible and robust method for enhancing DPLL(T)-style SMT solvers with proof-generation capabilities. Our method maintains separate Boolean-level and theory-level proofs, and weaves them together into one coherent artifact. Each theory-specific solver is called upon lazily, a posteriori, to prove precisely those solution steps it is responsible for and that are needed for the final proof. We present an implementation of our technique in the CVC4 SMT solver, capable of producing unsatisfiability proofs for quantifier-free queries involving uninterpreted functions, arrays, bitvectors and combinations thereof. We discuss an evaluation of our tool using industrial benchmarks and benchmarks from the SMT-LIB library, which shows promising results.","PeriodicalId":6479,"journal":{"name":"2016 Formal Methods in Computer-Aided Design (FMCAD)","volume":"13 1","pages":"93-100"},"PeriodicalIF":0.0,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75777590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employ the idea of network invariants to handle correctness for arbitrary depths in the hierarchy. Orthogonally, we leverage a parameterized model checker (Cubicle) to allow for a parametric number of children at each internal node of the tree. We believe this is the first time these two distinct dimensions of configuration have been together tackled in a verification approach, and also the first time a proof of an observational preorder (as required by network invariants) has been formulated inside a parametric model checker. Aside from the natural up/down communication between a child and a parent, we allow for peer-to-peer communication, since many real protocol optimizations rely on this paradigm. The paper details the Neo theory, which is built upon the Input-Output Automata formalism, and demonstrates the approach on an example hierarchical cache coherence protocol.","PeriodicalId":6479,"journal":{"name":"2016 Formal Methods in Computer-Aided Design (FMCAD)","volume":"30 1","pages":"101-108"},"PeriodicalIF":0.0,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77683254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
