osdi 2021 accepted papers

Welcome to the 16th USENIX Symposium on Operating Systems Design and Implementation (OSDI '22) submissions site. This yielded 6% fewer TLB miss stalls, and 26% reduction in memory wasted due to fragmentation. Timothy Roscoe is a Full Professor in the Systems Group of the Computer Science Department at ETH Zurich, where he works on operating systems, networks, and distributed systems, and is currently head of department. To adapt to different workloads, prior works mix or switch between a few known algorithms using manual insights or simple heuristics. PC members are not required to read supplementary material when reviewing the paper, so each paper should stand alone without it. Mothy received a PhD in 1995 from the Computer Laboratory of the University of Cambridge, where he was a principal designer and builder of the Nemesis OS. The symposium emphasizes innovative research as well as quantified or insightful experiences in systems design and implementation. We develop MAGE, an execution engine for SC that efficiently runs SC computations that do not fit in memory. First, GNNAdvisor explores and identifies several performance-relevant features from both the GNN model and the input graph, and use them as a new driving force for GNN acceleration.

NrOS replicates kernel state on each NUMA node and uses operation logs to maintain strong consistency between replicas. Although the number of submissions is lower than the past, it's likely only due to the late announcement; being in my first OSDI PC, I think the quality of the submitted and accepted papers remains as high as ever. Third, GNNAdvisor capitalizes on the GPU memory hierarchy for acceleration by gracefully coordinating the execution of GNNs according to the characteristics of the GPU memory structure and GNN workloads. A PC member is a conflict if any of the following three circumstances applies: Institution: You are currently employed at the same institution, have been previously employed at the same institution within the past two years (not counting concluded internships), or are going to begin employment at the same institution during the review period. Such centralized engines are in a perfect position to censor content and violate users privacy, undermining some of the key tenets behind decentralization. If your accepted paper should not be published prior to the event, please notify production@usenix.org. We develop a prototype of Zeph on Apache Kafka to demonstrate that Zeph can perform large-scale privacy transformations with low overhead. All submissions will be treated as confidential prior to publication on the USENIX OSDI 21 website; rejected submissions will be permanently treated as confidential. The file system performance of the proposed ZNS+ storage system was 1.33--2.91 times better than that of the normal ZNS-based storage system. Sponsored by USENIX in cooperation with ACM SIGOPS. She also has made contributions in network security, including scalable data expiration, distributed algorithms despite malicious participants, and DDOS prevention techniques. Of the 26 submitted artifacts: 26 artifacts received the Artifacts Available badge (100%). This kernel is scaled across NUMA nodes using node replication, a scheme inspired by state machine replication in distributed systems. DMon speeds up PostgreSQL, one of the most popular database systems, by 6.64% on average (up to 17.48%). Our approach outperforms existing file systems on a block SSD by a wide margin 6.2 on average for metadata-intensive benchmarks. Here, we focus on hugepage coverage. The chairs may reject abstracts or papers on the basis of egregious missing or extraneous conflicts. The ZNS+ also allows each zone to be overwritten with sparse sequential write requests, which enables the LFS to use threaded logging-based block reclamation instead of segment compaction. In this paper, we present P3, a system that focuses on scaling GNN model training to large real-world graphs in a distributed setting. In the Ethereum network, decentralized Ethereum clients reach consensus through transitioning to the same blockchain states according to the Ethereum specification. As a result, the design of a file system with respect to space management and crash consistency is simplified, requiring only 10.8K LOC for full functionality. Lifting predicates and crash framing make the specification easy to use for developers, and logically atomic crash specifications allow for modular reasoning in GoJournal, making the proof tractable despite complex concurrency and crash interleavings. Researchers from the Software Systems Laboratory bagged a Best Paper Award at the 16th USENIX Symposium on Operating Systems Design and Implementation (OSDI 2021). Accepted papers will be allowed 14 pages in the proceedings, plus references. We implement a variant of a log-structured merge tree in the storage device that not only indexes file objects, but also supports transactions and manages physical storage space. Widely used log-search tools like Elasticsearch and Splunk Enterprise index the logs to provide fast search performance, yet the size of the index is within the same order of magnitude as the raw log size. Papers accompanied by nondisclosure agreement forms will not be considered. Important Dates Abstract registrations due: Thursday, December 3, 2020, 3:00 pm PST Complete paper submissions due: Thursday, December 10, 2020, 3:00pm PST Author Response Period USENIX Security '21 has three submission deadlines. Our evaluation shows that NrOS scales to 96 cores with performance that nearly always dominates Linux at scale, in some cases by orders of magnitude, while retaining much of the simplicity of a sequential kernel. Compared to a state-of-the-art fuzzer, Fluffy improves the fuzzing throughput by 510 and the code coverage by 2.7 with various optimizations: in-process fuzzing, fuzzing harnesses for Ethereum clients, and semantic-aware mutation that reduces erroneous test cases. We build Polyjuice based on our learning framework and evaluate it against several existing algorithms. Registering abstracts a week before paper submission is an essential part of the paper-reviewing process, as PC members use this time to identify which papers they are qualified to review. We also verified a simple NFS server using GoJournals specs, which confirms that they are helpful for application verification: a significant part of the proof doesnt have to consider concurrency and crashes. The 15th USENIX Symposium on Operating Systems Design and Implementation seeks to present innovative, exciting research in computer systems. GoJournal is implemented in Go, and Perennial is implemented in the Coq proof assistant. We implemented the ZNS+ SSD at an SSD emulator and a real SSD. Professor Veloso is on leave from Carnegie Mellon University as the Herbert A. Simon University Professor in the School of Computer Science, and the past Head of the Machine Learning Department. The 15th USENIX Symposium on Operating Systems Design and Implementation (OSDI '21) will take place as a virtual event on July 1416, 2021. Four months after we reported the bugs to Geth developers, one of the bugs was triggered on the mainnet, and caused nodes using a stale version of Geth to hard fork the Ethereum blockchain. Moreover, to handle dynamic workloads, Nap adopts a fast NAL switch mechanism. A graph neural network (GNN) enables deep learning on structured graph data. However, existing enclave designs fail to meet the requirements of scalability demanded by new scenarios like serverless computing, mainly due to the limitations in their secure memory protection mechanisms, including static allocation, restricted capacity and high-cost initialization. If in doubt about whether your submission to OSDI 2021 and your upcoming submission to SOSP are the same paper or not, please contact the PC chairs by email. 1 Acknowledgements: Paper prepared for the post-conference workshop on Food for Thought: Economic Analysis in Anticipation of the Next Farm Bill at the Agricultural and Applied Economics Association annual meeting, Austin, TX . As has been standard practice in OSDI and SOSP in recent years, we will allow authors to submit quick responses to PC reviews: they will be made available to the PC before the final online discussion and PC meeting. The full program will be available in May 2021. Sanitizers detect unsafe actions such as invalid memory accesses by inserting checks that are validated during a programs execution. This paper presents Dorylus: a distributed system for training GNNs. By submitting a paper, you agree that at least one of the authors will attend the conference to present it. Submission of a response is optional. Sat, Aug 7, 2021 3 min read researches review. Authors may use this for content that may be of interest to some readers but is peripheral to the main technical contributions of the paper. We observe that scalability challenges in training GNNs are fundamentally different from that in training classical deep neural networks and distributed graph processing; and that commonly used techniques, such as intelligent partitioning of the graph do not yield desired results. Mothy's current research centers on Enzian, a powerful hybrid CPU/FPGA machine designed for research into systems software. However, a plethora of recent data breaches show that even widely trusted service providers can be compromised. Instead, we propose addressing the root cause of the heuristics problem by allowing software to explicitly specify to the device if submitted requests are latency-sensitive.

When further combined with a simple caching strategy, our evaluation shows that P3 is able to outperform existing state-of-the-art distributed GNN frameworks by up to 7. These scripts often make pages slow to load, partly due to a fundamental inefficiency in how browsers process JavaScript content: browsers make it easy for web developers to reason about page state by serially executing all scripts on any frame in a page, but as a result, fail to leverage the multiple CPU cores that are readily available even on low-end phones. SanRazor adopts a novel hybrid approach it captures both dynamic code coverage and static data dependencies of checks, and uses the extracted information to perform a redundant check analysis. However, Addra improves message latency in this architecture, which is a key performance metric for voice calls. In experiments with real DL jobs and with trace-driven simulations, Pollux reduces average job completion times by 37-50% relative to state-of-the-art DL schedulers, even when they are provided with ideal resource and training configurations for every job. If you have any questions about conflicts, please contact the program co-chairs. Message from the Program Co-Chairs. Our evaluation on the SPEC benchmarks shows that SanRazor can reduce the overhead of sanitizers significantly, from 73.8% to 28.062.0% for AddressSanitizer, and from 160.1% to 36.6124.4% for UndefinedBehaviorSanitizer (depending on the applied reduction scheme).

For example, optimistic concurrency control (OCC) is better than two-phase-locking (2PL) under low contention, while the converse is true under high contention. For instance, the following are not sufficient grounds to specify a conflict with a PC member: they have reviewed the work before, they are employed by your competitor, they are your personal friend, they were your post-doc advisor or advisee, or they had the same advisor as you. We convert five state-of-the-art PM indexes using Nap. Mothy joined the Computer Science Department ETH Zurich in January 2007 and was named Fellow of the ACM in 2013 for contributions to operating systems and networking research. The papers will be available online to everyone beginning on the first day of the conference, July 14, 2021. OSDI 2021 papers summary. In particular, I'll argue for re-engaging with what computer hardware really is today and give two suggestions (among many) about how the OS research community can usefully do this, and exploit what is actually a tremendous opportunity. This approach misses possible optimization opportunities as transformations that only preserve equivalence on subsets of the output tensors are excluded. The 20th ACM Workshop on Hot Topics in Networks (HotNets 2021) will bring together researchers in computer networks and systems to engage in a lively debate on the theory and practice of computer networking.
