Description: DynamoRIO is a runtime code manipulation system that supports code transformations on any part of a program, while it executes. DynamoRIO exports an interface for building dynamic tools for a wide variety of uses: program analysis and understanding, profiling, instrumentation, optimization, translation, etc. Unlike many dynamic tool systems, DynamoRIO is not limited to insertion of callouts/trampolines and allows arbitrary modifications to application instructions via a powerful IA-32/AMD64 instruction manipulation library. DynamoRIO provides efficient, transparent, and comprehensive manipulation of unmodified applications running on stock operating systems (Windows or Linux) and commodity IA-32 and AMD64 hardware.
DynamoRIO's powerful API abstracts away the details of the underlying infrastructure and allows the tool builder to concentrate on analyzing or modifying the application's runtime code stream. API documentation is included in the release package and can also be browsed online.

Previous description:

The DynamoRIO Collaboration - Dynamo from Hewlett-Packard Laboratories + RIO (Runtime Introspection and Optimization) from MIT's Laboratory for Computer Science.

The DynamoRIO dynamic code modification system, joint work between Hewlett-Packard and MIT, is being released as a binary package with an interface for both dynamic instrumentation and optimization. The system is based on Dynamo from Hewlett-Packard Laboratories. It operates on unmodified native binaries and requires no special hardware or operating system support. It is implemented for both IA-32 Windows and Linux, and is capable of running large desktop applications.

The system's release was announced at a PLDI tutorial on June 16, 2002, titled "On the Run - Building Dynamic Program Modifiers for Optimization, Introspection and Security." Here is the tutorial abstract:

In the new world of software, which heavily utilizes dynamic class loading, DLLs and interconnected components, the power and reach of static analysis is diminishing. An exciting new paradigm of dynamic program optimization, improving the performance of a program while it is being executed, is emerging. In this tutorial, we will describe intricacies of building a dynamic optimizer, explore novel application areas such as program introspection and security, and provide details of building your own dynamic code modifier using DynamoRIO. DynamoRIO, a joint development between HP Labs and MIT, is a powerful dynamic code modification infrastructure capable of running existing binaries such as Microsoft Office Suite. It runs on both Windows and Linux environments. We are offering a free release of DynamoRIO for non-commercial use. A copy of the DynamoRIO release, which includes the binary and a powerful API, will be provided to the attendees.
