Motherboard terdiri dari berbagai komponen elektronik seperti slot prosesor, socket memori, konektor daya, port USB, VGA, dan PCI yang memfasilitasi komunikasi antar komponen komputer lainnya seperti prosesor, memori, kartu grafis, dan periferal. Setiap komponen memiliki fungsi tersendiri seperti menghubungkan prosesor, menyimpan data sementara, dan menghubungkan perangkat keras tambahan.
The document discusses implementing PCIe Address Translation Services (ATS) in ARM-based systems-on-chips (SoCs). It describes an example ARM server system with various components like CPUs, memory controllers, and I/O devices. It then explains how ATS works to improve memory access performance by allowing devices to cache address translations locally instead of relying solely on the IOMMU. The document outlines the typical components involved in ATS like the address translation cache, translating agent, and address translation protection table. It also describes how the ARM System MMU (SMMU) implements ATS and supports distributed address translation caching by endpoints.

AMD and the new “Zen” High Performance x86 Core at Hot Chips 28AMD
The document summarizes a presentation about AMD's new "Zen" x86 CPU core architecture. The Zen architecture provides a 40% increase in instructions per clock compared to previous cores through improvements in the core engine, caches, floating point capabilities, and the addition of simultaneous multithreading. The Zen core was designed from the ground up to optimize performance and power efficiency across applications from notebooks to supercomputers.
Profiling the ACPICA Namespace and Event HandingSUSE Labs Taipei
This document summarizes a presentation about profiling the ACPI namespace and event handling. It discusses the key components of ACPICA and how it interacts with the Linux kernel. It describes how definition blocks are parsed to build the ACPI namespace, and how fixed events and general purpose events (GPEs) are handled through event detection and dispatching to handlers in the kernel or by evaluating control methods.

Talk by Brendan Gregg from Facebook's Performance @Scale: "Linux performance analysis has been the domain of ancient tools and metrics, but that's now changing in the Linux 4.x series. A new tracer is available in the mainline kernel, built from dynamic tracing (kprobes, uprobes) and enhanced BPF (Berkeley Packet Filter), aka, eBPF. It allows us to measure latency distributions for file system I/O and run queue latency, print details of storage device I/O and TCP retransmits, investigate blocked stack traces and memory leaks, and a whole lot more. These lead to performance wins large and small, especially when instrumenting areas that previously had zero visibility. This talk will summarize this new technology and some long-standing issues that it can solve, and how we intend to use it at Netflix."
Motherboard notebook berfungsi untuk menghubungkan komponen-komponen laptop seperti RAM, processor, dan VGA yang terintegrasi. Berbeda dengan motherboard PC yang lebih besar dan memiliki slot-slot tambahan, motherboard notebook lebih kecil dengan semua komponen terpadu. Motherboard notebook juga menggunakan adaptor dan baterai sebagai sumber daya utamanya.
El documento analiza las tarjetas madre Tm 598, Tm 830, Tm 805 y Tm 755, describiendo sus partes y ubicaciones. Concluye que las fuentes de alimentación V.ATX y V.AT pueden estar organizadas en diferentes lugares y que el chipset y el socket suelen estar ubicados en el mismo sitio.
QEMU Disk IO Which performs Better: Native or threads?Pradeep Kumar
Pradeep Kumar Surisetty from Red Hat presented a comparison of native and threaded I/O performance in QEMU disk I/O. He outlined KVM I/O architecture, storage transport options in KVM including virtio-blk configurations, and benchmark tools used. Performance testing was done with various disk types, file systems, images and configurations. Native generally outperformed threads for random I/O workloads, while threads sometimes showed better performance for sequential reads, especially with multiple VMs.

Introduction to Bioimage Analysis in R
This workshop covers basic methods of the image processing and image analysis in R using the Bioconductor package “EBImage” and the Orchestra platform. In addition, the image dataset is obtained from ExperimentHub using the “BioImageDbs” package. Using this dataset, we perform a supervised image segmentation using the U-NET model, one of deep learning models, provided by the rMiW package.
このワークショップでは、BioconductorパッケージであるEBImageを使って、Rでの画像処理・画像解析の基本的な方法を扱う。次に、BioImageDbsパッケージを用いて、ExperimentHubからの画像データの取得を行う。さらに、rMiWパッケージが提供する、Deep learningモデルの1つであるU-NETモデルを用いて、教師有り画像セグメンテーション(領域分割)を学び。このワークショップは、Orchestra環境にて実施する。

Systematic Interaction Analysis of Human Lipocalin-type Prostaglandin D Synthase with Small Lipophilic Ligands
This document provides instructions for installing R and using shell commands from within R on a CentOS 7 system. It explains how to install R using yum by first installing the EPEL repository and enabling it. It then shows how to use the system() function to run bash, tcsh, or other shell scripts from within R. The document also provides an example csh script and shows how to make it executable. Finally, it describes how to optionally install the GNOME desktop environment.
