  • Optimizing HLT Code for Run-Time Efficiency
    Optimizing HLT code for run-time efficiency Public Note Issue: 1 Revision: 0 Reference: LHCb-PUB-2010-017 Created: September 6, 2010 Last modified: November 4, 2010 LHCb-PUB-2010-017 04/11/2010 Prepared by: Axel Thuressona, Niko Neufeldb aLund,Sweden bCERN, PH Optimizing HLT code for run-time efficiency Ref: LHCb-PUB-2010-017 Public Note Issue: 1 Date: November 4, 2010 Abstract An upgrade of the High level trigger (HLT) farm at LHCb will be inevitable due to the increase in luminosity at the LHC. The upgrade will be done in two main ways. The first way is to make the software more efficient and faster. The second way is to increase the number of servers in the farm. This paper will concern both of these two ways divided into three parts. The first part is about NUMA, modern servers are all built with NUMA so an upgrade of the HLT farm will consist of this new architecture. The present HLT farm servers consists of the architecture UMA. After several tests it turned out that the Intel-servers that was used for testing (having 2 nodes) had very little penalty when comparing the worst-case the optimal-case. The conclusions for Intel-servers are that the NUMA architecture doesn’t affect the existing software negative. Several tests was done on an AMD-server having 8 nodes, and hence a more complicated structure. Non-optimal effects could be observed for this server and when comparing the worst-case with the optimal-case a big difference was found. So for the AMD-server the NUMA architecture can affect the existing software negative under certain circumstances.

  • Understanding the Linux Kernel, 3Rd Edition by Daniel P
    1 Understanding the Linux Kernel, 3rd Edition By Daniel P. Bovet, Marco Cesati ............................................... Publisher: O'Reilly Pub Date: November 2005 ISBN: 0-596-00565-2 Pages: 942 Table of Contents | Index In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: • Memory management, including file buffering, process swapping, and Direct memory Access (DMA) • The Virtual Filesystem layer and the Second and Third Extended Filesystems • Process creation and scheduling • Signals, interrupts, and the essential interfaces to device drivers • Timing • Synchronization within the kernel • Interprocess Communication (IPC) • Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it's more than just an academic exercise.

  • KVM Message Passing Performance
    Message Passing Workloads in KVM David Matlack, [email protected] 1 Overview Message Passing Workloads Loopback TCP_RR IPI and HLT DISCLAIMER: x86 and Intel VT-x Halt Polling Interrupts and questions are welcome! 2 Message Passing Workloads ● Usually, anything that frequently switches between running and idle. ● Event-driven workloads ○ Memcache ○ LAMP servers ○ Redis ● Multithreaded workloads using low latency wait/signal primitives for coordination. ○ Windows Event Objects ○ pthread_cond_wait / pthread_cond_signal ● Inter-process communication ○ TCP_RR (benchmark) 3 Message Passing Workloads Intuition: Workloads which don't involve IO virtualization should run at near native performance. Reality: Message Passing Workloads may not involve any IO but will still perform nX worse than native. ● (loopback) Memcache: 2x higher latency. ● Windows Event Objects: 3-4x higher latency. 4 Message Passing Workloads ● Microbenchmark: Loopback TCP_RR ○ Client and Server ping-pong 1-byte of data over an established TCP connection. ○ Loopback: No networking devices (real or virtual) involved. ○ Performance: Latency of each transaction. ● One transaction: 1.

  • Torwards a More Scalable KVM Hypervisor
    Torwards a more Scalable KVM Hypervisor KVM FORUM 2018 Wanpeng Li [email protected] Agenda • Paravirtualized TLB shootdown • Exitless IPIs • Disable mwait/hlt/pause vmexits to improve latency TLB Shootdown Preemption • When executing inside a virtual machine environment, OS level synchronization primitives such as locking, tlb shootdown and RCU are faced with significant challenges due to the scheduling behavior of the underlying host scheduler. Operations that are ensured to last only a short amount of time on bare-metal hardware, are capable of taking considerably longer when running virtualized. TLB Shootdown Preemption • A TLB is a cache of translation from memory virtual address to physical address. When a CPU changes virtual to physical mapping of an address, it needs to invalidate other CPUs' stale mapping in their respective caches. This process is called TLB shootdown. • Modern operating systems consider TLB shootdown operations to be performance critical and so optimize them to exhibit very low latency. The implementation of these operations is therefore architected to ensure that shootdowns can be completed with very low latencies through the use of IPI based signalling. TLB Shootdown Preemption • Remote TLB flush does a busy wait which is fine in bare-metal scenario. But with-in the guest, the vCPUs might have been pre-empted or blocked. In this scenario, the initiator vCPU would end up busy-waiting for a long amount of time; it also consumes CPU unnecessarily to wake up the target of the shootdown. TLB Shootdown Preemption • The time between the preemption and rescheduling of a remote target vCPU is often orders of magnitude larger than the latency that TLB Shootdown operations were designed for.
