In the new world of software, which heavily utilizes dynamic class loading,
dynamically linked libraries, 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. However, research in this area is
difficult due to lack of tools, especially tools that are able to handle
real applications in their entirety.

A collaboration between HP Labs and MIT has produced DynamoRIO, a dynamic
code modification system for the IA-32 platform. The DynamoRIO system is
meant to be an infrastructure for not only dynamic optimization but other
applications such as program introspection and security. DynamoRIO can be
used to build tools ranging from simple profilers that instrument the code
stream to gather statistics to full-fledged dynamic optimization passes.

DynamoRIO 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,
such as Microsoft Office and Adobe photoshop.

HP and MIT are offering a free release of DynamoRIO for non-commercial use.
The release includes the DynamoRIO binaries and an interface for building
custom dynamic code modifiers. The interface supports applications such as
dynamic instrumentation and optimization, with a powerful API for
manipulating IA-32 instructions.

The release is available from:
