Open Source C Profiling Software

The goal of the project is now to develop a user library called libpfm4 to help setup performance events for use with the perf_events Linux kernel interface. The development of the perfmon kernel subsystem, libpfm and pfmon has now stopped.

OProfile is a low-overhead, transparent profiler for Linux, capable of instruction-grain profiling of all processes, shared libraries, the kernel and device drivers, via the hardware performance counters.

ebizzy is designed to generate a workload resembling common web application server workloads. It is highly threaded, has a large in-memory working set, and allocates and deallocates memory frequently.

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

KCachegrind visualizes traces generated by profiling, including a tree map and a call graph visualization of the calls happening. It's designed to be fast for very large programs like KDE applications.

The sandbox libraries (libsandbox & pysandbox) are an open-source suite of software components for C/C++ and Python developers to create automated profiling tools and watchdog programs. The API's are designed for executing and instrumenting simple (single process) tasks, featuring policy-based behavioral auditing, resource quota, and statistics collecting. The sandbox libraries were originally designed and utilized as the core security module of a full-fledged online judge system for ACM/ICPC training. They have since then evolved into a general-purpose tool for binary program testing, profiling, and security restriction. The sandbox libraries are currently maintained by the OpenJudge Alliance (http://openjudge.net/) as a standalone, open-source project to facilitate various assignment grading solutions for IT/CS education. See project page at https://github.com/openjudge/sandbox for details.

Open|SpeedShop is an open source multi platform Linux performance tool which is targeted to support performance analysis of applications running on both single node and large scale IA64, IA32, EM64T, AMD64, PPC, Blue Gene, ARM and Cray platforms.

The goal of this project is to develop the OS-independent, obtrusive, customizable, extensible, generic logging and tracing software mechanism.

Developer tool for automatic runtime tracing software errors with various resources. Number of resources virtually unlimited.

ParTools allows the interactive analysis of a C program execution profile and data dependencies to facilitate the discovery and selection of suitable parallelization candidates in a manual parallelization process. The flow does not assume any specific parallelization technique, thus it can be broadly applied. The original (serial) C source is automatically annotated to trace the execution profile and data dependencies at run-time. The annotated program is then executed using a significant (but small) data set selected by the developer. The data collected is cross-referenced with the original source and can be interactively analyzed graphically to determine the best parallelization candidates and techniques.

Performance profiler is designed to profile single and multi-threading software.

A collection of library code and tools for application execution profiling and performance testing. You can create stopwatches to time select portions of your code. You can measure differences (often to sub-millisecond accuracy) between clocks on different machines. You can log application events in a .csv format for subsequent analysis. You can also generate CPU loading logs in a .csv format.

Warning: Older projects may have to be compiled with -DDEBUG_NEW_CONFIG_HAVE_DEPRECATED Debug_New offers the possibility of debugging memoryleaks, not only (note the "not only"; that's just one of its functions) in a <report-memory-leaks-on-shutdown> kind of way, but implemented using memory-states. - Cross platform + Cross compiler support (only utilizes the preprocessor and template-voodoo-magic for c++) - Supports C and C++ - Supports gcc and g++ - Supports pthread and any posix platform - Multithreading is supported. - Easy to use and install (just include the header and link the source). - Easily debug memory-leaks. - Easily debug dangling pointers. - Easily debug deallocation method correctness. - Easily debug array index errors (when writing past the end). - Easily profile memory usage and track down memory hawks. - Click-And-Goto-Source support for Visual Studio. - Integrated compatibility for new, new[], delete, delete[], malloc, calloc, realloc, free

Discrete Event Gnu Advanced Scheduling for plug-in replacement of pthread compatible applications. Generates deterministic execution runs suitable for discrete event simulations and formal verification.

The fastest malloc we've seen; works particularly well with threads and STL. Also: thread-friendly heap-checker, heap-profiler, and cpu-profiler.

iostat is a tool for the creation of IO statistics of precompiled binaries in Unix like systems (Linux/MacOS).

ATrace is a tracing tool uses the ptrace interface. ATrace allows tuning and troubleshooting of applications without modification of the source or object code and can be parameterized via config files and logs the addresses of executed instructions.

An implementation of the Open Group's Application Response Measurement (ARM) Version 4 standard. The ARM standard describes a means of breaking an application down into it's constituent transactions, and measuring response time across multiple tiers.

This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .

Parsing, interpreting, checking and profiling C application (ISO/IEC 9899:1999 (E))

CQSAT is a powerful, comprehensive and extensible framework for static analysis of program source code and detection of software defects.

The Cache emulator (shortly CE) can simulates the behavior of caches inside SMP system and compute the number of cache misses during a computation. All measurements are done in the "off-line" mode on the one CPU.

Diagonal can be used for: - getting descriptive statistics such as mean/median/mode with your program producing a sample - finding a root of an equation your program defines - calculating a fixed point of a function your program defines - detecting a cycle of a fuction your program defines as well as - decoding a VCDIFF file
