Hence, kernel developers are constantly refining synchronization within OS kernels to improve scalability at the risk of introducing subtle bugs. 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. 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. SC is being increasingly adopted by industry for a variety of applications. 23 artifacts received the Artifacts Functional badge (88%).

We prove that DistAI is guaranteed to find the -free inductive invariant that proves the desired safety properties in finite time, if one exists. Second, it innovates on the underlying cryptographic machinery and constructs a new private information retrieval scheme, FastPIR, that reduces the time to process oblivious access requests for mailboxes. Camera-ready submission (all accepted papers): 2 April 2021; Main conference program: 27-28 April 2021; All deadline times are . We introduce a hybrid cryptographic protocol for privacy-adhering transformations of encrypted data. The overhead of GPT is 5% for memory-intensive workloads (e.g., Redis) and negligible for CPU-intensive workloads (e.g., RV8 and Coremarks). 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. Simultaneous submission of the same work to multiple venues, submission of previously published work, or plagiarism constitutes dishonesty or fraud. (Jan 2019) Our REPT paper won a best paper at OSDI'18 (Oct 2018) I will serve in the SOSP'19 PC.

HotNets provides a venue for discussing innovative ideas and for debating future research agendas in networking. High-performance tensor programs are critical for efficiently deploying deep neural network (DNN) models in real-world tasks. 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. Abstract registrations that do not provide sufficient information to understand the topic and contribution (e.g., empty abstracts, placeholder abstracts, or trivial abstracts) will be rejected, thereby precluding paper submission. Submissions violating the detailed formatting and anonymization rules will not be considered for review. She is the author of the textbook Interconnections (about network layers 2 and 3) and coauthor of Network Security. Our approach outperforms existing file systems on a block SSD by a wide margin 6.2 on average for metadata-intensive benchmarks. Indeed, it is a prime target for powerful adversaries such as nation states.

PLDI seeks outstanding research that extends and/or applies programming-language concepts to advance the field of computing. The key insight guiding our design is computation separation. A.H. Hunter, Jane Street Capital; Chris Kennelly, Paul Turner, Darryl Gove, Tipp Moseley, and Parthasarathy Ranganathan, Google. Penglai also reduces the latency of secure memory initialization by three orders of magnitude and gains 3.6x speedup for real-world applications (e.g., MapReduce). We argue that a key-value interface between a file system and an SSD is superior to the legacy block interface by presenting KEVIN. Academic and industrial participants present research and experience papers that cover the full range of theory and practice of computer . Existing algorithms are designed to work well for certain workloads. Consensus bugs are bugs that make Ethereum clients transition to incorrect blockchain states and fail to reach consensus with other clients. Perennial 2.0 makes this possible by introducing several techniques to formalize GoJournals specification and to manage the complexity in the proof of GoJournals implementation. Writing a correct operating system kernel is notoriously hard. In this paper, we present P3, a system that focuses on scaling GNN model training to large real-world graphs in a distributed setting. To adapt to different workloads, prior works mix or switch between a few known algorithms using manual insights or simple heuristics. Although SSDs can be simplified under the current ZNS interface, its counterpart LFS must bear segment compaction overhead. Taking place in Carlsbad, CA from 11-13 July, OSDI is a highly selective flagship conference in computer science, especially on the topic of computer systems.

Petuum Awarded OSDI 2021 Best Paper for Goodput-Optimized Deep Learning If your accepted paper should not be published prior to the event, please notify production@usenix.org. Submitted November 12, 2021 Accepted January 20, 2022. To achieve low overhead, selective profiling gathers runtime execution information selectively and incrementally. We focus on NVMe storage devices and show that it is natural to express these semantics in the kernel and the application and only requires a modest two-bit change to the device interface. For example, optimistic concurrency control (OCC) is better than two-phase-locking (2PL) under low contention, while the converse is true under high contention. Our evaluation shows that, compared to existing participant selection mechanisms, Oort improves time-to-accuracy performance by 1.2X-14.1X and final model accuracy by 1.3%-9.8%, while efficiently enforcing developer-specified model testing criteria at the scale of millions of clients.

Today, privacy controls are enforced by data curators with full access to data in the clear. 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. We present selective profiling, a technique that locates data locality problems with low-enough overhead that is suitable for production use. If you have any questions about conflicts, please contact the program co-chairs. PET discovers and applies program transformations that improve computation efficiency but only maintain partial functional equivalence. blk-switch uses this insight to adapt techniques from the computer networking literature (e.g., multiple egress queues, prioritized processing of individual requests, load balancing, and switch scheduling) to the Linux kernel storage stack. 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). An evaluation of Addra on a cluster of 80 machines on AWS demonstrates that it can serve 32K users with a 99-th percentile message latency of 726 msa 7 improvement over a prior system for text messaging in the same threat model.

SOSP 2021 - Symposium on Operating Systems Principles Existing decentralized systems like Steemit, OpenBazaar, and the growing number of blockchain apps provide alternatives to existing services. All the times listed below are in Pacific Daylight Time (PDT). Cores can safely and concurrently read from their local kernel replica, eliminating remote NUMA accesses. 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. GoJournals goal is to bring the advantages of journaling for code to specs and proofs. Used Zotero to organize papers about the stress and diffusion between anode and electrolyte and made a summary . To remedy this, we introduce DeSearch, the first decentralized search engine that guarantees the integrity and privacy of search results for decentralized services and blockchain apps. Web pages today commonly include large amounts of JavaScript code in order to offer users a dynamic experience. The abstractions we design for the privacy resource mirror those defined by Kubernetes for traditional resources, but there are also major differences. One important reason for the high cost is, as we observe in this paper, that many sanitizer checks are redundant the same safety property is repeatedly checked leading to unnecessarily wasted computing resources. Welcome to the SOSP 2021 Website. Report - Systems Research Artifacts Call for Papers - EuroSys 2022 We demonstrate that the hardware thread scheduler is able to lower RPC tail response time by about 5 while enabling the system to sustain 20% higher load, relative to traditional thread scheduling techniques. 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). Uniquely, Dorylus can take advantage of serverless computing to increase scalability at a low cost.
