This approach misses possible optimization opportunities as transformations that only preserve equivalence on subsets of the output tensors are excluded. Weak Links in Authentication Chains: A Large-scale Analysis of Email Sender Spoofing Attacks We propose a learning-based framework that instead explicitly optimizes concurrency control via offline training to maximize performance. For conference information, see: . In contrast, CLP achieves significantly higher compression ratio than all commonly used compressors, yet delivers fast search performance that is comparable or even better than Elasticsearch and Splunk Enterprise. Based on the observation that invariants are often concise in practice, DistAI starts with small invariant formulas and enumerates all strongest possible invariants that hold for all samples. However, your OSDI submission must use an anonymized name for your project or system that differs from any used in such contexts. Ethereum is the second-largest blockchain platform next to Bitcoin. Authors are also encouraged to contact the program co-chairs,
[email protected], if needed to relate their OSDI submissions to relevant submissions of their own that are simultaneously under review or awaiting publication at other venues. The biennial ACM Symposium on Operating Systems Principles is the world's premier forum for researchers, developers, programmers, and teachers of computer systems technology. Because DistAI starts with the strongest possible invariants, if the SMT solver fails, DistAI does not need to discard failed invariants, but knows to monotonically weaken them and try again with the solver, repeating the process until it eventually succeeds. Alas, existing profiling techniques incur high overhead when used to identify data locality problems and cannot be deployed in production, where programs may exhibit previously-unseen performance problems. The key to our solution, Horcrux, is to account for the non-determinism intrinsic to web page loads and the constraints placed by the browsers API for parallelism. DMons targeted optimizations provide 16.83% speedup on average (up to 53.14%), compared to a baseline that uses the highest level of compiler optimization. We present case studies and end-to-end applications that show how Storm lets developers specify diverse policies while centralizing the trusted code to under 1% of the application, and statically enforces security with modest type annotation overhead, and no run-time cost. Submitted papers must be no longer than 12 single-spaced 8.5 x 11 pages, including figures and tables, plus as many pages as needed for references, using 10-point type on 12-point (single-spaced) leading, two-column format, Times Roman or a similar font, within a text block 7 wide x 9 deep. Swapnil Gandhi and Anand Padmanabha Iyer, Microsoft Research. People often assume that blockchain has Byzantine robustness, so adding it to any system will make that system super robust against any calamity. She has been recognized with many industry honors including induction into the National Academy of Engineering, the Inventor Hall of Fame, The Internet Hall of Fame, Washington State Academy of Science, and lifetime achievement awards from USENIX and SIGCOMM. You must not improperly identify a PC member as a conflict if none of these three circumstances applies, even if for some other reason you want to avoid them reviewing your paper. GoJournals goal is to bring the advantages of journaling for code to specs and proofs. 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. One classical approach is to increase the efficiency of an allocator to minimize the cycles spent in the allocator code. After request completion, an I/O device must decide either to minimize latency by immediately firing an interrupt or to optimize for throughput by delaying the interrupt, anticipating that more requests will complete soon and help amortize the interrupt cost. We demonstrate that Marius achieves the same level of accuracy but is up to one order of magnitude faster. Author Response Period Existing decentralized systems like Steemit, OpenBazaar, and the growing number of blockchain apps provide alternatives to existing services.

DeSearch uses trusted hardware to build a network of workers that execute a pipeline of small search engine tasks (crawl, index, aggregate, rank, query). For general conference information, see https://www . Memory allocation represents significant compute cost at the warehouse scale and its optimization can yield considerable cost savings. Log search and log archiving, despite being critical problems, are mutually exclusive. . Submissions violating the detailed formatting and anonymization rules will not be considered for review. A.H. Hunter, Jane Street Capital; Chris Kennelly, Paul Turner, Darryl Gove, Tipp Moseley, and Parthasarathy Ranganathan, Google. We demonstrate that KEVIN reduces the amount of I/O traffic between the host and the device, and remains particularly robust as the system ages and the data become fragmented. 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. Conference Dates: Apr 12, 2021 - Apr 14, 2021. Submission of a response is optional. Evaluations show that Vegito can perform 1.9 million TPC-C NewOrder transactions and 24 TPC-H-equivalent queries per second simultaneously, which retain the excellent performance of specialized OLTP and OLAP counterparts (e.g., DrTM+H and MonetDB). After three years working on web-based collaboration systems at a startup in North Carolina, he joined Sprint's Advanced Technology Lab in Burlingame, California, in 1998, working on cloud computing and network monitoring. Finding the inductive invariant of the distributed protocol is a critical step in verifying the correctness of distributed systems, but takes a long time to do even for simple protocols.

We implement and evaluate a suite of applications, including MICA, Raft and Set Algebra for document retrieval; and we demonstrate that the nanoPU can be used as a high performance, programmable alternative for one-sided RDMA operations. The 15th USENIX Symposium on Operating Systems Design and Implementation (OSDI '21) will take place as a virtual event on July 1416, 2021. This is the first OSDI in an odd year as OSDI moves to a yearly cadence. We also show that Marius can scale training to datasets an order of magnitude beyond a single machine's GPU and CPU memory capacity, enabling training of configurations with more than a billion edges and 550 GB of total parameters on a single machine with 16 GB of GPU memory and 64 GB of CPU memory. Kirk Rodrigues, Yu Luo, and Ding Yuan, University of Toronto and YScope Inc. Existing frameworks optimize tensor programs by applying fully equivalent transformations, which maintain equivalence on every element of output tensors.

HotNets provides a venue for discussing innovative ideas and for debating future research agendas in networking. 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. Her specialties include network routing protocols and network security. OSDI is "a premier forum for discussing the design, implementation, and implications of systems software." A total of six research papers from the department were accepted to the . We conclude with a discussion of additional techniques for improving the allocator development process and potential optimization strategies for future memory allocators. The biennial ACM Symposium on Operating Systems Principles is the world's premier forum for researchers, developers, programmers, vendors and teachers of operating system technology. Sanitizers detect unsafe actions such as invalid memory accesses by inserting checks that are validated during a programs execution. The OSDI Symposium emphasizes innovative research as well as quantified or insightful experiences in systems design and implementation. To evaluate the security guarantees of Storm, we build a formally verified reference implementation using the Labeled IO (LIO) IFC framework. Attaching supplementary material is optional; if your paper says that you have source code or formal proofs, you need not attach them to convince the PC of their existence. (Visa applications can take at least 30 working days to process.) Performance experiments show that GoNFS provides similar performance (e.g., at least 90% throughput across several benchmarks on an NVMe disk) to Linuxs NFS server exporting an ext4 file system, suggesting that GoJournal is a competitive journaling system. Upon these two primitives, our system can scale to thousands of concurrent enclaves with high resource utilization and eliminate the high-cost initialization of secure memory using fork-style enclave creation without weakening the security guarantees. Concurrency control algorithms are key determinants of the performance of in-memory databases. Metadata from voice calls, such as the knowledge of who is communicating with whom, contains rich information about peoples lives. We identify that current systems for learning the embeddings of large-scale graphs are bottlenecked by data movement, which results in poor resource utilization and inefficient training.

To adapt to different workloads, prior works mix or switch between a few known algorithms using manual insights or simple heuristics. SC is being increasingly adopted by industry for a variety of applications. In this paper, we present P3, a system that focuses on scaling GNN model training to large real-world graphs in a distributed setting. Collaboration: You have a collaboration on a project, publication, grant proposal, program co-chairship, or editorship within the past two years (December 2018 through March 2021). See the USENIX Conference Submissions Policy for details. 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. However, Addra improves message latency in this architecture, which is a key performance metric for voice calls. High-performance tensor programs are critical for efficiently deploying deep neural network (DNN) models in real-world tasks.

Her robot soccer teams have been RoboCup world champions several times, and the CoBot mobile robots have autonomously navigated for more than 1,000km in university buildings. 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. Of the 26 submitted artifacts: 26 artifacts received the Artifacts Available badge (100%). A glance at this year's OSDI program shows that Operating Systems are a small niche topic for this conference, not even meriting their own full session. Web pages today commonly include large amounts of JavaScript code in order to offer users a dynamic experience. How can we design systems that will be reliable despite misbehaving participants? All deadline times are 23:59 hrs UTC. However, the existing one-size-fits-all GNN implementations are insufficient to catch up with the evolving GNN architectures, the ever-increasing graph size, and the diverse node embedding dimensionality. The key insight in blk-switch is that Linux's multi-queue storage design, along with multi-queue network and storage hardware, makes the storage stack conceptually similar to a network switch. OSDI 2021 papers summary. Furthermore, such performance can be achieved without any modification in applications, network hardware, kernel CPU schedulers and/or kernel network stack. The copyback-aware block allocation considers different copy costs at different copy paths within the SSD. This paper describes the design, implementation, and evaluation of Addra, the first system for voice communication that hides metadata over fully untrusted infrastructure and scales to tens of thousands of users.
