Dynamic Probe Class Library (DPCL) is an object based C++ class library that provides the necessary infrastructure to allow tool developers and sophisticated tool users to build parallel and serial tools through technology called dynamic instrumentation.

DPCL takes the basic components needed by tool developers and encapsulates them into C++ classes. Each of these classes provide the member functions necessary to interact and dynamically instrument a running application with software patches called probes. Dynamic instrumentation provides the flexibility for tools to insert probes into applications as the application is running and only where it is needed.

SGI SpeedShop provides a wide variety of experiments to help users identify and remove performance obstacles, pinpoint system resource usage, and detect memory leaks. Open/SpeedShop for Linux OS-based computing systems running on a wide range of computing platforms will be made available to the open-source community to accelerate independent use and development. It will feature core SpeedShop components such as support for single system image and cluster configurations, exclusive and inclusive user time sampling, program counter sampling, MPI call tracing, input/output tracing, floating point exception tracing, and CPU hardware performance counter experiments. The new version's modular design will also enable users to extend the tool's functionality by adding their own performance experiments to monitor application performance.

Dynaprof is a dynamic instrumentation and performance analysis tool that uses DynInst and DPCL.

MetaSim is two sets of tools developed by PMaC used in PMaC's Performance Prediction Framework. The first set of tools is the MetaSim Tracer. This is a memory trace tool design to collect information about an application's memory usage. The MetaSim Tracer is a semi-cycle accurate simulator that works by gathering statistics on expected cache hit rates of routines and loops in an application.

The second set of tools is the MetaSim Convolver. This is used in a step in the PMaC Performance Prediction Framework. The Convolver takes a Application Signature from the MetaSim Tracer and a Machine Profile from the MAPS probe to combine them for a single-processor or per-processor performance prediction of that application on the given machine.

Stride is a tool to dynamically instrument load/stores in binary to obtain information about memory usage patterns in the data reference stream of an application. It employs an online algorithm to detect linear memory access patterns. Instrumentation can be selectively applied and disabled during execution. At the conclusion of the run, detailed function-level stream statistics are calculated.

TAU (Tuning and Analysis Utilities) is a visual programming and performance analysis environment for parallel C++ and HPF. TAU is implemented in C and C++ and uses Tcl/Tk for graphics. The TAU tools are implemented as graphical hypertools. While they are distinct tools, they act in concert as if they were a single application. TAU is part of the HPC++ project.

Many types of tools have similar needs for data collection features and user interfaces. For example, many tools display source code and either annotate it with data or allow the user to click on parts of the source display to initiate an action or display more detailed information. Tool Gear handles much of the source code and data display, allowing tool developers to focus on the unique aspects of their codes. Tool Gear can work with the Dynamic Probe Class Library (DPCL) to collect data from instrumentation installed at runtime in programs, or it can receive data sent to it from other sources.
