RCU is well-known at the kernel-level for providing a way to synchronize shared data structures in read-often, update-rarely scenarios.
The development of a RCU library at the userspace application level has been mainly driven by the need for efficient synchronization of userspace tracing control data structures.
IBM kindly agreed to allow distribution of RCU-related code in a LGPL library, which makes it available for everyone to use. This can have large impact on the design of highly scalable applications performing caching of frequent requests, like domain name servers, proxy and web servers.
This presentation will discuss about the class of applications which could benefit from using the userspace RCU library.
The userspace RCU library is available under the LGPL license at http://www.lttng.org/urcu .
Univa and SUSE at SC17: Scaling Machine Learning for SUSE Linux Containers, S...Ian Lumb
Armed with nothing more than an Apache Spark toting SUSE Linux laptop, you have all the trappings required to prototype the application of Machine Learning against your data-science needs. From programmability in Scala, Java or Python, to built-in support for Machine Learning via MLlib, Spark is an exceedingly effective enabler that allows you to rapidly produce results. Of course, as soon as your prototyping proves successful, you'll want to scale out to embrace the volume, variety and velocity that characterizes today's demands in Big Data Analytics ... in production. Because Spark is as comfortable on an isolated laptop as it is in a distributed-computing environment, addressing these ‘Big Data’ requirements in production boils down to effectively and efficiently embracing SUSE Linux containers, servers, clusters and clouds. As case studies will illustrate, this transition from prototype to production can be made successfully.
Managing Containerized HPC and AI Workloads on TSUBAME3.0Ian Lumb
By leveraging the operating environment provided by SUSE Linux Enterprise Server, Univa® Grid Engine® manages workloads for the Tokyo Institute of Technology’s (TITECH) TSUBAME3.0 supercomputer. In many respects, this is an exceptional supercomputer that combines the leading-edge compute (Intel Xeon CPUs and NVIDIA Pascal P100 GPUs) and interconnect (Intel Omni-Path) capabilities demanded by traditional HPC as well as Deep Learning workloads. TITECH’s desire to make extensive use of containerization via Docker is also a distinctive aspect of the overall platform that currently is being implemented. As noted in booth presentations at past SC events, SUSE Linux and Univa Grid Engine have a highly complementary affinity for Docker containers. In this year’s presentation, aspects of TSUBAME3.0 motivated projects for managing containerized workloads will be highlighted.

OSDC 2013 | Distributed Storage with GlusterFS by Dr. Udo SeidelNETWAYS
So-called shared file systems are known for a long time for all IT administrators using Linux, Unix and Windows. The network based and also the cluster data systems are almost an old hat. Since a while distributed data systems become popular. The GlusterFS project is not new, but the community didn´t caught notice until the takeover of RedHat. Significant characteristics of this data system are the new approach to meta-data management and the new modular structure.
This presentation gives an insight into the approaches of data systems, and will explain the architecture and describe the first steps to set up a GlusterFS-cluster.
Hardware once reserved to HPC systems is entering the datacenter. Cyprien will describe an effort to help developers leverage its new capabilities. Its integration to H2O, along with tools like Caffe, is accelerating and making the platform more powerful. #h2ony
Server as the core of the information systems in today's business operations playing a pivotal role, data storage on server is becoming the lifeline to maintain the normal operation of the millions of businesses and organizations. Correct choice of independent control of the server or cluster systems and storage devices can improve system performance and operational capabilities. The user request rate and response time of business server data storage system are dependent on the selection of the storage devices. These devices can greatly affect system performance. To effectively protect data and give linear performance for iSCSI initiator, it is required to modify the iSCSI target driver to provide Gluster file system backend storage as distributed block device. This paper aims at discussing ways of modifying iSCSI Target (ISTGT) driver to support Gluster file system.

To exchange data between processes without the overhead of locking/syscall, shared memory can be used. libshdata/telemetry offers a lock free circular buffer with timestamped data chunks to handle some typical uses cases found in drones:
One process for flying stack, and one a more processes for video computing.
Video processing can access drone attitude precisely with the frame
Logging of all the telemetry exchanged in shared memory is easily written in a file or to a remote ground station
Also work in AMP configurations

Java one2015 - Work With Hundreds of Hot Terabytes in JVMsSpeedment, Inc.
Presentation Summary: By leveraging on memory mapped files, the Chronicle Engine supports large maps that easily can exceed the size of your server’s RAM, thus allowing application developers to create huge JVM:s where data can be obtained quickly and with predictable latency. The Chronicle Engine can be synchronized with an underlying database using Speedment so that your in-memory maps will be “alive” and change whenever data changes in the underlying database. Speedment can also automatically derive domain models directly from the database so that you can start using the solution very quickly. Because the Java Maps are mapped onto files, the maps can also be shared instantly between several JVM:s and when you restart a JVM, it may start very quickly without having to reload data from the underlying database. The mapped files can be hundreds of terabytes which has been done in real world deployment cases.
Agenda:
In this talk we will present various locking mechanisms implemented in the linux kernel.
From System V locks to raw spinlocks and the RT patch.

Kubernetes @ Squarespace: Kubernetes in the DatacenterKevin Lynch
This talk was presented at SRE NYC Meetup on August 16, 2017 at Squarespace HQ.
https://www.youtube.com/watch?v=UJ1QAKprVr4
As the engineering teams at Squarespace grow, we have been building more and more microservices. However, this has added operational strain as we try to shoehorn a growing, complex dynamic environment into our static data center infrastructure. We needed to rethink how we handle deployments, dependency management, resource allocation, monitoring, and alerting. Docker containerization and Kubernetes orchestration helps us tackle many of these problems, but the journey has been challenging. In this talk, we’ll discuss the challenges of running Kubernetes in a datacenter and how we switched to a more SLA-focused alert structure than per instance health with Prometheus and AlertManager.

Доклад: Все что вы хотели знать о CRIU, но стеснялись спросить...
Андрей Вагин пришёл в Parallels в 2006 году, занимается разработкой ядра Linux, контейнерной системы OpenVZ и сравнительно молодого проекта CRIU. В 2008 году закончил МФТИ.
Все что вы хотели знать о CRIU, но стеснялись спросить...
Проект CRIU (Checkpoint /Restore in Userspace) позвляет содавать контрольные точки и осуществлять миграцию сервисов или контейнеров в реальном времени. Некоторое время назад проект преодолел очередной рубеж и вышел из стадии эксперимента. Следующая зада — интегрировать CRIU в сторонние проекты, такие как OpenVZ, LXC, Docker, OpenMPI. Доклад раскроет всю магию процедуры сохранения и восстановления процессов. Вы узнаете, как в любой процесс можно незаметно подсадить паразита-разведчика и вытянуть все тайны, как системный вызов rt-sigreturn пригодился совсем не там, где родился. Будет показано внутреннее устройство CRIU (без цензуры), блистательные моменты реализации, и почему всё-таки пришлось добавить патчи в ядро. Во второй части доклада будут рассмотрены механизмы взаимодействия CRIU с другими проектами и наиболее частые вопросы интеграции.

CONFidence 2017: Escaping the (sand)box: The promises and pitfalls of modern ...PROIDEA
Users of modern Linux containerization technologies are frequently at loss with what kind of security guarantees are delivered by tools they use. Typical questions range from Can these be used to isolate software with known security shortcomings and rich history of security vulnerabilities? to even Can I used such technique to isolate user-generated and potentially hostile assembler payloads?
Modern Linux OS code-base as well as independent authors provide a plethora of options for those who desire to make sure that their computational loads are solidly confined. Potential users can choose from solutions ranging from Docker-like confinement projects, through Xen hypervisors, seccomp-bpf and ptrace-based sandboxes, to isolation frameworks based on hardware virtualization (e.g. KVM).
The talk will discuss available today techniques, with focus on (frequently overstated) promises regarding their strength. In the end, as they say: “Many speed bumps don’t make a wall
In this deck, Paul Isaacs from Linaro presents: State of ARM-based HPC. This talk provides an overview of applications and infrastructure services successfully ported to Aarch64 and benefiting from scale.
"With its debut on the TOP500, the 125,000-core Astra supercomputer at New Mexico’s Sandia Labs uses Cavium ThunderX2 chips to mark Arm’s entry into the petascale world. In Japan, the Fujitsu A64FX Arm-based CPU in the pending Fugaku supercomputer has been optimized to achieve high-level, real-world application performance, anticipating up to one hundred times the application execution performance of the K computer. K was the first computer to top 10 petaflops in 2011."

In the past, much effort has been invested in high performance kernel tracing tools, but now focus in the tracing community seems to be shifting over to efficient user space application tracing. By providing joint kernel and user space tracing, developers can have deeper insights in their applications latencies. This presentation covers the ongoing efforts within the LTTng project to enhance system-wide tracing at the user space level. It discusses instrumentation sources such as Tracepoints, Uprobes, and SystemTAP SDT providers, along with their integration with LTTng. A brief overview of the latest and upcoming features of the user space tracer is presented. It also discusses ongoing efforts in the area of trace format and control protocol standardisation. Finally, our presentation includes challenging glibc-related issues encountered during LTTng-UST development, opening the discussion on how to improve and collaborate on user-space instrumentation.
The targeted audience is user space and kernel developers, those interested in tracing infrastructure, shared system libraries, and application instrumentation.
Low-cost microcontrollers are being used more and more often in embedded applications that previously may have used a microprocessor. Microcontrollers often run a real-time operating system (RTOS) rather than a full operating system like Linux.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

12. > Generic RCU
● Detection of quiescent state:
– rcu_read_lock()/rcu_read_unlock() mark the
beginning/end of the critical sections
– Counts nesting level
● Suitable for library use
● Higher read-side overhead than QSBR
due to added memory barriers

● Same quiescent state detection as
Generic RCU
● Suitable for library use, but reserves a
signal
● Read-side close to QSBR performance
– Remove memory barriers from
rcu_read_lock()/rcu_read_unlock().
– Replaced by memory barriers in signal

● Queues RCU callbacks for deferred
batched execution
● Wait-free unless per-thread queue is full
● “Worker thread” executes callbacks
periodically
● Energy-efficient, uses sys_futex()

22. > RCU-Friendly Applications
● Multithreaded applications with read-
often shared data
– Cache
● Name servers
● Proxy
● Web servers with static pages
– Configuration
● Low synchronization overhead
● Dynamically modified without restart

23. > RCU-Friendly Applications
● Libraries supporting multithreaded
applications
– Tracing library, e.g. lib UST (LTTng port for
userspace tracing)
● http://git.dorsal.polymtl.ca/?p=ust.git

24. > RCU-Friendly Applications
● Libraries supporting multithreaded
applications (cont.)
– Typing/data structure support
● Typing system
– Creation of a class is a rare event
– Reading class structure happens at object
creation/destruction (_very_ often)
– Applies to gobject
● Used by: gtk/gdk/glib/gstreamer...
● Efficient hash tables
● Glib “quarks”

25. > RCU-Friendly Applications
● Routing tables in userspace
● Userspace network stacks
● Userspace signal-handling
– Signal-safe read-side
– Could implement an inter-thread signal
multiplexer
● Your own ?
