Most existing schedulers expect users to specify the number of resources for each job, often leading to inefficient resource use. Editor in charge: Daniel Petrolia . Dorylus is up to 3.8 faster and 10.7 cheaper compared to existing sampling-based systems. NrOS replicates kernel state on each NUMA node and uses operation logs to maintain strong consistency between replicas. . This change is receiving considerable attention in the architecture and security communities, for example, but in contrast, so-called OS researchers are mostly in denial. While compiler-based techniques have been proposed to improve data locality, they depend on heuristics, which can sometimes hurt performance. Storm ensures security using a Security Typed ORM that refines the (type) abstractions of each layer of the MVC API with logical assertions that describe the data produced and consumed by the underlying operation and the users allowed access to that data.

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). 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. 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. We convert five state-of-the-art PM indexes using Nap. J.P. Morgan AI Research partners with applied data analytics teams across the firm as well as with leading academic institutions globally. Contact your program co-chairs, osdi21chairs@usenix.org, or the USENIX office, submissionspolicy@usenix.org. 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). Marius is open-sourced at www.marius-project.org. Sam Kumar, David E. Culler, and Raluca Ada Popa, University of California, Berkeley. (Visa applications can take at least 30 working days to process.) We describe Fluffy, a multi-transaction differential fuzzer for finding consensus bugs in Ethereum. We demonstrate that Marius achieves the same level of accuracy but is up to one order of magnitude faster. AI enables principled representation of knowledge, complex strategy optimization, learning from data, and support to human decision making. In the Ethereum network, decentralized Ethereum clients reach consensus through transitioning to the same blockchain states according to the Ethereum specification. Based on this observation, P3 proposes a new approach for distributed GNN training. 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. Notification of conditional accept/reject for revisions: 3 March 2022. Papers so short as to be considered extended abstracts will not receive full consideration. The device then "calibrates" its interrupts to completions of latency-sensitive requests. A graph neural network (GNN) enables deep learning on structured graph data. Swapnil Gandhi and Anand Padmanabha Iyer, Microsoft Research. While verifying GoJournal, we found one serious concurrency bug, even though GoJournal has many unit tests. Authors should email the program co-chairs, osdi21chairs@usenix.org, a copy of the related workshop paper and a short explanation of the new material in the conference paper beyond that published in the workshop version. OSDI takes a broad view of the systems area and solicits contributions from many fields of systems practice, including, but not limited to, operating systems, file and storage systems, distributed systems, cloud computing, mobile systems, secure and reliable systems, systems aspects of big data, embedded systems, virtualization, networking as it relates to operating systems, and management and troubleshooting of complex systems. Despite their extensive use for debugging and vulnerability discovery, sanitizer checks often induce a high runtime cost. 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. Mothy's current research centers on Enzian, a powerful hybrid CPU/FPGA machine designed for research into systems software. PLDI seeks outstanding research that extends and/or applies programming-language concepts to advance the field of computing. PDF Why Has Personality Psychology Played an Outsized Role in the 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. Commonly used log archival and compression tools like Gzip provide high compression ratio, yet searching archived logs is a slow and painful process as it first requires decompressing the logs. If your paper is accepted and you need an invitation letter to apply for a visa to attend the conference, please contact conference@usenix.org as soon as possible. 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. Sep 2021 - Present 1 year 7 months. OSDI '21 Technical Sessions | USENIX This is the first OSDI in an odd year as OSDI moves to a yearly cadence. Our evaluation shows that DistAI successfully verifies 13 common distributed protocols automatically and outperforms alternative methods both in the number of protocols it verifies and the speed at which it does so, in some cases by more than two orders of magnitude. Advisor: You have a past or present association as thesis advisor or advisee. VLDB 2021 - 47th International Conference on Very Large Data Bases NrOS is primarily constructed as a simple, sequential kernel with no concurrency, making it easier to develop and reason about its correctness. The abstractions we design for the privacy resource mirror those defined by Kubernetes for traditional resources, but there are also major differences. USENIX, like other scientific and technical conferences and journals, prohibits these practices and may, on the recommendation of a program chair, take action against authors who have committed them. As the emerging trend of graph-based deep learning, Graph Neural Networks (GNNs) excel for their capability to generate high-quality node feature vectors (embeddings). We present Nap, a black-box approach that converts concurrent persistent memory (PM) indexes into NUMA-aware counterparts.

Researchers from the Software Systems Laboratory bagged a Best Paper Award at the 16th USENIX Symposium on Operating Systems Design and Implementation (OSDI 2021). 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. With an aim to improve time-to-accuracy performance in model training, Oort prioritizes the use of those clients who have both data that offers the greatest utility in improving model accuracy and the capability to run training quickly. SOSP 2021 - Symposium on Operating Systems Principles Professor Veloso has been recognized with a multiple honors, including being a Fellow of the ACM, IEEE, AAAS, and AAAI. 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. The 15th USENIX Symposium on Operating Systems Design and Implementation (OSDI '21) will take place as a virtual event on July 14-16, 2021. Authors of each accepted paper must ensure that at least one author registers for the conference, and that their paper is presented in-person at the conference. PC members are not required to read supplementary material when reviewing the paper, so each paper should stand alone without it. Overall, the OSDI PC accepted 31 out of 165 submissions. And yet, they continue to rely on centralized search engines and indexers to help users access the content they seek and navigate the apps. For general conference information, see https://www . 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. Forgot your password? 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. The NAL eliminates remote PM accesses to hot items without inducing extra local PM accesses. Concretely, Dorylus is 1.22 faster and 4.83 cheaper than GPU servers for massive sparse graphs. Secure Computation (SC) is a family of cryptographic primitives for computing on encrypted data in single-party and multi-party settings. Authors are also encouraged to contact the program co-chairs, osdi21chairs@usenix.org, if needed to relate their OSDI submissions to relevant submissions of their own that are simultaneously under review or awaiting publication at other venues. OSDI - Guide Proceedings Typically, monolithic kernels share state across cores and rely on one-off synchronization patterns that are specialized for each kernel structure or subsystem. Submissions may include as many additional pages as needed for references but not for appendices. To enable FL developers to interpret their results in model testing, Oort enforces their requirements on the distribution of participant data while improving the duration of federated testing by cherry-picking clients. Each new model trained with DP increases the bound on data leakage and can be seen as consuming part of a global privacy budget that should not be exceeded. However, a plethora of recent data breaches show that even widely trusted service providers can be compromised. Papers must be in PDF format and must be submitted via the submission form. We describe PrivateKube, an extension to the popular Kubernetes datacenter orchestrator that adds privacy as a new type of resource to be managed alongside other traditional compute resources, such as CPU, GPU, and memory. OSDI 2021 papers summary | hacklog 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. At a high level, Addra follows a template in which callers and callees deposit and retrieve messages from private mailboxes hosted at an untrusted server. Software Systems Laboratory Wins Best Paper Awards at the OSDI and With her students, she had led research in AI, with a focus on robotics and machine learning, having concretely researched and developed a variety of autonomous robots, including teams of soccer robots, and mobile service robots. EuroSys 2021 2019 - Present. To evaluate the security guarantees of Storm, we build a formally verified reference implementation using the Labeled IO (LIO) IFC framework. Samantha Vaive - Member Board Of Trustees - Lansing Community College She also invented the spanning tree algorithm, which transformed Ethernet from a technology that supported a few hundred nodes, to something that can support large networks. By submitting a paper, you agree that at least one of the authors will attend the conference to present it. We present the results of a 1% experiment at fleet scale as well as the longitudinal rollout in Googles warehouse scale computers. To this end, we propose GNNAdvisor, an adaptive and efficient runtime system to accelerate various GNN workloads on GPU platforms. Owing to the sequential write-only zone scheme of the ZNS, the log-structured file system (LFS) is required to access ZNS solid-state drives (SSDs). If you are uncertain about how to anonymize your submission, please contact the program co-chairs, osdi21chairs@usenix.org, well in advance of the submission deadline. OSDI'20: 14th USENIX Conference on Operating Systems Design and ImplementationNovember 4 - 6, 2020 ISBN: 978-1-939133-19-9 Published: 04 November 2020 Sponsors: ORACLE, VMware, Google Inc., Amazon, Microsoft Get Alerts for this Conference Save to Binder Export Citation Bibliometrics Citation count 96 Downloads (6 weeks) 317 Downloads (12 months) P3 exposes a simple API that captures many different classes of GNN architectures for generality. Some recent schedulers choose job resources for users, but do so without awareness of how DL training can be re-optimized to better utilize the provided resources. The experimental results show that Penglai can support 1,000s enclave instances running concurrently and scale up to 512GB secure memory with both encryption and integrity protection. The symposium emphasizes innovative research as well as quantified or insightful experiences in systems design and implementation. We built an FPGA prototype of the nanoPU fast path by modifying an open-source RISC-V CPU, and evaluated its performance using cycle-accurate simulations on AWS FPGAs. If the conference registration fee will pose a hardship for the presenter of the accepted paper, please contact conference@usenix.org.

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 have made Fluffy publicly available at https://github.com/snuspl/fluffy to contribute to the security of Ethereum. To help more profitably utilize sanitizers, we introduce SanRazor, a practical tool aiming to effectively detect and remove redundant sanitizer checks. Today, privacy controls are enforced by data curators with full access to data in the clear. The co-chairs may then share that paper with the workshops organizers and discuss it with them. 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 paper review process is double-blind. We present NrOS, a new OS kernel with a safer approach to synchronization that runs many POSIX programs. 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.
