Efficient memory disaggregation with Infiniswap
Efficient memory disaggregation with Infiniswap Gu et al., NSDI '17 If we move performance numbers onto a human scale (let 1ns of processor time = 1 second of human time) then it's easier to get an intuition - for me at least - of the relative cost of different operations. In this world, it takes … Continue reading Efficient memory disaggregation with Infiniswap
SGXIO: Generic trusted I/O path for Intel SGX
SGXIO: Generic trusted I/O path for Intel SGX Weiser & Werner, CODASPY '17 Intel's SGX provides hardware-secured enclaves for trusted execution of applications in an untrusted environment. Previously we've looked at Haven, which uses SGX in the context of cloud infrastructure, SCONE which shows how to run docker containers under SGX, and Panoply which looks at … Continue reading SGXIO: Generic trusted I/O path for Intel SGX
Panoply: Low-TCB Linux applications with SGX enclaves
Panoply: Low-TCB Linux applications with SGX enclaves Shinde et al., NDSS, 2017 Intel's Software Guard Extensions (SGX) supports a kind of reverse sandbox. With the normal sandbox model you're probably used to, we download untrusted code and run it in a trusted environment that we control. SGX supports running trusted code that you wrote, but … Continue reading Panoply: Low-TCB Linux applications with SGX enclaves
Enlightening the I/O path: A holistic approach for application performance
Enlightening the I/O Path: A holistic approach for application performance Kim et al., FAST '17 Lots of applications contain a mix of foreground and background tasks. Since we're at the file system level here, for application, think Redis, MongoDB, PostgreSQL and so on. Typically user requests are considered foreground tasks, and tasks such as housekeeping, … Continue reading Enlightening the I/O path: A holistic approach for application performance
IX: A protected dataplane operating system for high throughput and low latency
IX: A Protected Dataplane Operating System for High Throughput and Low Latency Belay et al. OSDI 2014 This is the second of Simon Peter's recommended papers in the 'Data Center OS Design' Research for Practice guide. Like Arrakis, IX splits the operating system into a control plane and data plane for networking. To quote Simon … Continue reading IX: A protected dataplane operating system for high throughput and low latency
Arrakis: the operating system is the control plane
Arrakis: The Operating System is the Control Plane - Peter et al. OSDI 2014 ACM Queue just introduced their "Research for Practice" series with Peter Bailis. Each edition contains 'expert curated guides to the best of CS research,' and in the first instalment Simon Peter selects a set of papers on data-center operating system trends, … Continue reading Arrakis: the operating system is the control plane
The Linux Scheduler: a Decade of Wasted Cores
The Linux Scheduler: a Decade of Wasted Cores - Lozi et al. 2016 This is the first in a series of papers from EuroSys 2016. There are three strands here: first of all, there's some great background into how scheduling works in the Linux kernel; secondly, there's a story about Software Aging and how changing … Continue reading The Linux Scheduler: a Decade of Wasted Cores
IncludeOS: A minimal, resource efficient unikernel for cloud systems
IncludeOS: A minimal, resource efficient unikernel for cloud systems - Bratterud et al. 2015 There has been lots of excitement around unikernels over the last year, and especially with the recent acquisition of the Unikernel Systems team by Docker (MirageOS, Mergeable Persistent Data Structures, Jitsu: Just-in time summoning of Unikernels). Whereas MirageOS is built around … Continue reading IncludeOS: A minimal, resource efficient unikernel for cloud systems
Split-Level IO Scheduling
Split-Level IO Scheduling - Yang et al. 2015 The central idea in today's paper is pretty simple: block-level I/O schedulers (the most common kind) lack the higher level information necessary to perform write-reordering and accurate accounting, whereas system-call level schedulers have the appropriate context but lack the low-level knowledge needed to build efficient schedulers - … Continue reading Split-Level IO Scheduling
