From Zero to still Zero: The most beautiful mistakes going into the cloud. OPEN KNOWLEDGE GmbH
"Cloud is the new Normal”, so Andrew R. Jassy (CIO AWS). Was also liegt näher, als genau jetzt den Schritt in die Cloud zu wagen? Passende Blaupausen dazu gibt es mehr als genug. Aber ist dieser Schritt wirklich so einfach, wie uns die verschiedenen Cloud-Anbieter glauben machen wollen? Natürlich nicht. Diese Session zeigt anhand typischer Antipattern, wie der Weg in die Cloud garantiert im Desaster endet und wie man sich dagegen wappnen kann. Ähnlichkeiten zu existierenden Projekten sind rein zufällig – oder auch nicht.
Netflix has over 20 million subscribers in the US and Canada and is expanding internationally.

It describes several inefficiencies in the Linux kernel TCP/IP stack related to shared resources between cores, broken data locality, and per-packet processing overhead. It then introduces mTCP, a user-level TCP/IP stack that addresses these issues through a thread model with pairwise threading, batch packet processing from I/O to applications, and a BSD-like socket API. mTCP achieves a 2.35x performance improvement over the kernel TCP/IP stack on a web server workload.
Flow-centric Computing - A Datacenter Architecture in the Post Moore EraRyousei Takano
1) The document proposes a new "flow-centric computing" data center architecture for the post-Moore era that focuses on data flows.
2) It involves disaggregating server components and reassembling them as "slices" consisting of task-specific processors and storage connected by an optical network to efficiently process data.
3) The authors expect optical networks to enable high-speed communication between processors, replacing general CPUs, and to potentially revolutionize how data is processed in future data centers.
A Look Inside Google’s Data Center NetworksRyousei Takano
1) Google has been developing their own data center network architectures using merchant silicon switches and centralized network control since 2005 to keep up with increasing bandwidth demands.
2) Their network designs have evolved from Firehose and Watchtower to the current Saturn and Jupiter networks, increasing port speeds from 1/10Gbps to 40/100Gbps and aggregate bandwidth from terabits to petabits per second.
3) Their network architectures employ Clos topologies with merchant silicon switches at the top-of-rack, aggregation, and spine layers and centralized control of traffic routing.

Exploring the Performance Impact of Virtualization on an HPC CloudRyousei Takano
The document evaluates the performance impact of virtualization on high-performance computing (HPC) clouds. Experiments were conducted on the AIST Super Green Cloud, a 155-node HPC cluster. Benchmark results show that while PCI passthrough mitigates I/O overhead, virtualization still incurs performance penalties for MPI collectives as node counts increase. Application benchmarks demonstrate overhead is limited to around 5%. The study concludes HPC clouds are promising due to utilization improvements from virtualization, but further optimization of virtual machine placement and pass-through technologies could help reduce overhead.
From Rack scale computers to Warehouse scale computersRyousei Takano
This document discusses the transition from rack-scale computers to warehouse-scale computers through the disaggregation of technologies. It provides examples of rack-scale architectures like Open Compute Project and Intel Rack Scale Architecture. For warehouse-scale computers, it examines HP's The Machine project using application-specific cores, universal memory, and photonics fabric. It also outlines UC Berkeley's FireBox project utilizing 1 terabit/sec optical fibers, many-core systems-on-chip, and non-volatile memory modules connected via high-radix photonic switches.

The authors demonstrate Apache CloudStack can seamlessly manage resources across emulated inter-cloud environments using Iris.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
