    CS192-24 TRACEPOINT NAMES ITS FIRST PRODUCT DEC spin-off Tracepoint Technology named its first product HiProf, as we suspected it would (CSN No 185), and described it as a graphical hierarchical profiler that will enable C++ developers to analyze the binaries of 32-bit x86 applications and figure out where modifications should be made. The first of a family, the tool is based on a patented Binary Code Instrumentation technology that displays a detailed analysis of an application's execution in Tracepoint's IDE. The company's core framework can handle executables and .dlls that have been generated by compiling software as well. Therefore, source code shouldn't have to be recompiled. The data can be viewed on a threads basis. HiProf is due out next month at $599 and runs on Win95 or NT 3.51 or later. It supports apps developed with VC++ 2.0 or above and Microsoft Developer Studio 4.03.

Since TestTrack works on compiled and linked binary code (no source code or obj files required), there=92s no need for recompiling or preprocessing so the entire process is dramatically quicker than with past generation tools. TestTrack analyzes and reports on coverage of several different types including; function coverage, class coverage, line coverage, branch coverage, multiple condition coverage, call-pair coverage and more. TestTrack allows you to selectively exclude portions of the code base , if desired, so you can analyze only those portions of an app that concern you. A robust and intuitive GUI displays results in "live" pie charts or bar graphs that let you drill down into the code represented with just a mouse click, extensive reporting capabilities include the ability to publish reports in html, and a powerful merge function allows you to merge the results of several test runs for total coverage analysis. In addition, TestTrack identifies dead code in your app which is no longer used but which can slow performance and bloat program size. An evaluation copy of the latest TestTrack beta is available for free download from TracePoint at TestTrack works on 32-bit apps generated with VC++ 2.x - 5.0. TracePoint is a recent spin-off of DIGITAL Equipment Corp, whose mission is to create and market advanced development tools for 32-bit Windows apps.

    Version 2.2 of the DIGITAL Continuous Profiling Infrastructure, a set of performance tools for Digital Alpha systems running Digital Unix, is available for general use.
    The Digital Continuous Profiling Infrastructure for Digital Alpha platforms permits continuous low-overhead profiling of entire systems, including the kernel, user programs, drivers, and shared libraries. The system is efficient enough that it can be left running all the time, allowing it to be used to drive online profile-based optimizations for production systems.
    The Continuous Profiling Infrastructure maintains a database of profile information that is incrementally updated for every executable image that runs. A suite of profile analysis tools analyzes the profile information at various levels. At one extreme, the tools show what fraction of cpu cycles were spent executing the kernel and each user program. At the other extreme, the tools show how long a particular instruction stalls on average, e.g., because of a D-cache miss.
    DCPI runs under Digital Unix V3.2 and V4.x, with a port to WindowsNT underway. It is free of charge. Further information, including papers and man pages, can be found at: The system was developed at Digital's Systems Research Center and Western Research Laboratory, both in Palo Alto, California. A paper describing the system, will appear at SOSP-16 in October. -- Send compilers articles to, meta-mail to

    The SimOS team at Stanford University is pleased to announce the second release of our complete machine simulation environment. If you are receiving this email, then you have downloaded an earlier version of SimOS or were deemed "someone who may be interested". If you would like to be taken off this infrequently used list, send mail to "" and we'll take you off of it immediately.

    For those of you who need a refresher, SimOS is a "complete machine simulator" in that it models the hardware of uniprocessor and multiprocessor computers in enough detail to boot and run commercial operating systems as well as applications designed for these operating systems. This includes databases, web servers, and other workloads that traditional simulation tools have trouble supporting. Furthermore, SimOS executes these workloads at high speeds and provides support for easily collecting detailed hardware and software performance information.

    There have been substantial improvements and enhancements since the first SimOS release including:

    * Support for the Digital Alpha architecture running the Digital Unix operating system.

    * Support for the MIPS 64-bit architecture.

    * More modular hardware simulator interfaces that simplify the process of adding new processor, memory system, and device models.

    SimOS is available free of charge for the research community and runs on several different hardware platforms. For download information, research papers, a discussion group, and more, visit the new SimOS web site at:

  • Connectix VirtualPC simulates a complete PC system including VGA, Audio Ethernet hardware and does sophisticated dynamic translation to achieve reasonable speeds (it's not exactly clear how well that works, but it seems that its achieved speed is between 25% and 80% native speed) and claims ``up to twice as fast as the competition.'' and

  • SoftWindows 98 is FWB Software's competitive product. Also, RealPC, also by FWB, is closer to VirtualPC in its design, it is a hardware-level emulator. See Note that both were originally developed by Insignia Solutions, see

  • Another interesting product is Inferno. See It describes the Inferno operating system, which is available both in native and application form and is VM-based, using dynamic translation to achieve (allegedly) a 1.5-2.5 times slowdown over native code. It is similar to TAOS in that it achieves application portability via a virtual machine.
