(Open) MPI, Parallel Computing, Life, the Universe, and Everything
(Open) MPI, Parallel Computing, Life, the Universe, and EverythingJeff Squyres This talk is a general discussion of the current state of Open MPI, and a deep dive on two new features:
1. The flexible process affinity system (I presented many of these slides at the Madrid EuroMPI'13 conference in September 2013).
2. The MPI-3 "MPI_T" tools interface.
I originally gave this talk at Lawrence Berkeley Labs on Thursday, November 7, 2013.
Using GTP on Linux with libgtpnl
Using GTP on Linux with libgtpnlKentaro Ebisawa The document discusses configuring GTP tunnels on Linux using the libgtpnl library. Key points:
- Linux kernels since 4.7 include GTP tunnel endpoint functionality in the gtp.c driver
- Libgtpnl provides tools to configure GTP tunnels via netlink without a control plane
- Configuration involves creating veth interfaces, loopbacks, GTP devices, and tunnels between endpoints using TEIDs and IP addresses
Kernel bug hunting
Kernel bug huntingAndrea Righi Debugging is an essential part of Linux kernel development. In
user-space we have the support of the kernel and many debugging tools, tracking down a kernel bug, instead, can be very difficult if you don't know the proper methodologies. This talk will cover some techniques to understand how the kernel works, hunt down and fix kernel bugs in order to become a better kernel developer.
Open MPI Explorations in Process Affinity (EuroMPI'13 presentation)
Open MPI Explorations in Process Affinity (EuroMPI'13 presentation)Jeff Squyres The document discusses Open MPI's Locality-Aware Mapping Algorithm (LAMA) interface for controlling process placement on parallel machines. It describes how LAMA allows users to specify regular mapping patterns of processes to resources. It also outlines the three main steps in MPI process placement with LAMA: 1) mapping processes to resources, 2) ordering processes, and 3) binding processes during launch according to the mapping. The goal is to provide a mechanism for exploring different process placements to minimize communication costs.

HCQC : HPC Compiler Quality Checker
HCQC : HPC Compiler Quality CheckerLinaro By Masaki Arai, Fujitsu Laboratories Ltd.
For numerical calculation programs on supercomputers, the kernel part occupies 80% or more of the execution time in many cases. Therefore, the quality of the code generated by the compiler for these kernel parts is significant. We created a tool, which is called HCQC, to aid in the investigation of the quality of the code generated by the compiler for the kernel part. In this presentation, we report the details of HCQC and the results of evaluating the quality of GCC and LLVM when compiling the kernel part of benchmark programs using HCQC.
Masaki Arai Bio
In 1992, He joined Fujitsu Laboratories Ltd. His research interests are in the area of compiler optimizations and computer architectures. He joined Linaro as member engineer in 2017.

Event machine
Event machinealmeidaricardo Event Machine is a library for Ruby that provides event-driven I/O. It uses the reactor pattern to achieve high scalability, performance, and stability. Event Machine powers the backends of many large sites by enabling asynchronous programming and handling many concurrent connections efficiently. It can be used with tools like Rails, Thin, Goliath, MongoDB, and RabbitMQ to build highly scalable web applications. Benchmarks show that using Event Machine can process many more requests per second than a traditional Rails app due to its asynchronous and non-blocking nature.
Cilium - Fast IPv6 Container Networking with BPF and XDP
Cilium - Fast IPv6 Container Networking with BPF and XDPThomas Graf We present a new open source project which provides IPv6 networking for Linux Containers by generating programs for each individual container on the fly and then runs them as JITed BPF code in the kernel. By generating and compiling the code, the program is reduced to the minimally required feature set and then heavily optimised by the compiler as parameters become plain variables. The upcoming addition of the Express Data Plane (XDP) to the kernel will make this approach even more efficient as the programs will get invoked directly from the network driver.

[Webinar Slides] Programming the Network Dataplane in P4Open Networking Summits This webinar explains why PISA chips are inevitable, provides overview of machine architecture of such switches, presents a brief primer on the P4 language with sample programs for a variety of networks and demonstrates a powerful network diagnostics application implemented in P4.
Programmability in SDNs is confined to the network control plane. The forwarding plane is still largely dictated by fixed-function switching chips. Our goal is to change that, and to allow programmers to define how packets are to be processed all the way down to the wire.
This is made possible by a new generation of high-performance forwarding chips. At the high-end, PISA (Protocol-Independent Switch Architecture) chips promise multi-Tb/s of packet processing. At the mid- and low-end of the performance spectrum, CPUs, GPUs, FPGAs, and NPUs already offer great flexibility with performance of a few tens to hundreds of Gb/s.
In addition to programmable forwarding chips, we also need a high-level language to dictate the forwarding behavior in a target independent fashion. "P4" (www.p4.org) is such a language. In P4, the programer declares how packets are to be processed, and a compiler generates a configuration for a PISA chip, or a programmable target in general. For example, the programmer might program the switch to be a top-of-rack switch, a firewall, or a load-balancer; and might add features to run automatic diagnostics and novel congestion control algorithms.

Two-level Just-in-Time Compilation with One Interpreter and One Engine
Two-level Just-in-Time Compilation with One Interpreter and One EngineYusuke Izawa This document proposes a two-level just-in-time compilation approach using one interpreter and one engine. It finds that by providing different interpreter definitions to the RPython meta-tracing compiler, different kinds of compilers and compilations can be derived, such as tracing, method, and threaded code compilers. The key idea is an adaptive RPython system that performs multitier compilation by generating different interpreters from a generic interpreter and driving the RPython engine accordingly. This challenges the assumption in the JIT community that a meta-tracing compiler can only perform tracing compilation.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
