developed with the Intel Performance Libraries benefit from new
architectural features of future generations of Intel processors simply by
relinking the application with upgraded versions of the libraries.
Enhanced Debugger (EDB)
The Enhanced Debugger (EDB) enables you to debug C++, Fortran
or mixed language programs running under Windows NT* or
Windows 2000 (not Windows 98). It allows you to display in a separate
window the contents of the eight registers, XMM0 through XMM7,
used by the Streaming SIMD Extensions and Streaming SIMD
Extensions 2. You may select one of five formats for the register fields:
byte (16 bytes); word (8 words); double word (4 double words); single
precision (4 single precision floating point); and double precision
(2 double precision floating point). When a register is updated, the new
value appears in red. The corresponding Streaming SIMD Extensions or
Streaming SIMD Extensions 2 instruction can be seen in the
disassembly window. For further detail on the features and use of the
Enhanced Debugger, refer to the online help.

The Intel
®
Threading Tools consist of the The Intel

Thread Checker
and Thread Profiler.
Intel
®
Thread Checker
The Intel Thread Checker locates programming errors (e.g., data races,
stalls and deadlocks) in threaded applications. Use the Intel Thread
Checker to find threading errors and reduce the amount of time you
spend debugging your threaded application.
