  FreeBSD has included support for Hardware Performance Monitoring Counters (hwpmc) for several years now. The hwpmc system provides access to counters that are present in all modern Intel and AMD CPUs, as well as other chipsets, and which give the programmer the ability to understand the low level performance issues that may effect their code. This talk will cover the motivation behind and basic usage of HWPMC.

  In the past ten years most of the research in network protocols has gone into TCP, leaving UDP to languish as a local configuration protocol. While the majority of Internet traffic is TCP, UDP remains the only IP protocol that works over multicast and as such has some specific, and interesting uses in some areas of computing. In 2008 we undertook a study of the performance of UDP multicast on both 1Gbps and 10Gbps Ethernet networks in order to see if changing the physical layer of the network would give a linear decrease in packet latency. To measure the possible gains we developed a new network protocol test program, mctest, which is capable of recording packet round trip times from many hosts simultaneously and which we believe accurately represents how many environments use multicast. The mctest program has been integrated into FreeBSD and is now being used to verify the proper operation of multicast on various pieces of 10Gbps hardware.

  The Google Summer of Code is a program designed to provide students with real world experience contributing to open source projects during the summer break in university studies. Each year Google selects a number of open source projects to act as mentoring organizations. Students are invited to submit project proposals for the open source projects that are most interesting to them. FreeBSD was one of the projects selected to participate in the inaugural Summer of Code in 2005 and we have participated each year since then. Over the past 4 years a total of 79 students have participated in the program and it has become a very significant source of new committers to FreeBSD. This talk will examine in detail the selection criteria for projects, the impact that successful projects have had, and some suggestions for how we can better leverage this program in the future.

  Many modern CPUs provide on chip counters for performance events such as retiring instructions and cache misses. The hwpmc driver and libraries in FreeBSD give systems administrators and programmers access to APIs which make it possible to measure performance without modifying source code and with minimal intrusion into application execution. This talk will be a brief introduction to HWPMC, and how to use it.

  Bio: George Neville-Neil is the co-author with Kirk McKusick of The Design and Implementation of the FreeBSD Operating System. He works on networking an operating systems for fun and profit.

  Our Topic: Network Protocol Development Tools and Techniques for FreeBSD
  > Our Speaker: George Neville-Neil, co-author of the "Design and Implementation of the FreeBSD Operating System" "daemon" book.
  > Our Topic: While computers have gotten faster and more powerful the tools we use to develop network protocols, such as TCP, UDP, IPv4 and IPv6 have not. Most network protocols are developed, in C, in the kernel, and require a lot of work to test. Over the past year or so I have been working with virtual machines, a couple of pieces of open source software, and begun developing a library for use in protocol testing. This talk will cover three topics:
  1. Developing and testing kernel code with Virtual Machines
  2. Finding good tests for networking code
  3. Packet Construction Set (PCS) a new library for writing protocol tests

  Thinking about thinking in code
  Proposed keynote talk

  This is not a talk that's specific to any BSD but is a more general talk about how we think about coding and how our thinking changes the way we code.

  I compare how we built systems to how other industries build their products and talk about what we can learn from how we work and from how others work as well.

• George Neville-Neil - Understanding and Tuning SCHED_ULE

  Understanding and Tuning SCHED_ULE

  With the advent of widespread SMP and multicore CPU architectures it was necessary to implement a new scheduler in the FreeBSD operating system. The SCHEDULE scheduler was added for the 5 series of FreeBSD releases and has now matured to the point where it is the default scheduler in the 7.1 release. While scheduling processes was a difficult enough task in the uniprocessor world, moving to multiple processors, and multiple cores, has significantly increased the number of problems that await engineers who wish to squeeze every last ounce of performance out of their system. This talk will cover the basic design of SCHEDULE and focus a great deal of attention on how to tune the scheduler for different workloads, using the sysctl interfaces that have been provided for that purpose.

  Understanding and tuning a scheduler used to be done only by operating systems designers and perhaps a small minority of engineers focusing on esoteric high performance systems. With the advent of widespread multi-processor and multi-core architectures it has become necessary for more users and administrators to decide how to tune their systems for the best performance. The SCHEDULE scheduler in FreeBSD provides a set of sysctl interfaces for tuning the scheduler at run time, but in order to use these interfaces effectively the scheduling process must first be understood. This presentation will give an overview of how SCHEDULE works and then will show several examples of tuning the system with the interfaces provided.

  The goal of modifying the scheduler's parameters is to change the overall performance of programs on the system. One of the first problems presented to the person who wants to tune the scheduler is how to measure the effects of their changes. Simply tweaking the parameters and hoping that that will help is not going to lead to good results. In our recent experiments we have used the top(1) program to measure our results.

  Networking from the Bottom Up: Device Drivers.

  In this tutorial I will describe how to write and maintain network drivers in FreeBSD and use the example of the Intel Gigabit Ethernet driver (igb) throughout the course.

  Students will learn the basic data structures and APIs necessary to implement a network driver in FreeBSD. The tutorial is general enough that it can be applied to other BSDs, and likely to other embedded and UNIX like systems while being specific enough that given a device and a manual the student should be able to develop a working driver on their own. This is the first of a series of lectures on network that I am developing over the next year or so.
