1.11 Visual Threads

Visual Threads is a new tool available on the Tru64 UNIX Associated

Products Volume 2 CD–ROM that lets you analyze your multithreaded

applications for potential logic and performance problems. It is licensed as

part of the Developer’s Toolkit for Tru64 UNIX.

You can use Visual Threads with DECthreads applications that use POSIX

threads (Pthreads) and with Java applications.

Visual Threads features include the following:

• Detects violation conditions based on the application of particular rules in

your application. Several predeﬁned rules look for data protection errors,

deadlock conditions, programming errors, and performance issues.

• Lets you use templates to deﬁne your own rules to specify criteria for

violation conditions.

• Keeps track of the events associated with the violations.

• Records events to a trace ﬁle so that you can play back and analyze them

later.

• Dynamically displays events as they occur, with controls for ﬁltering.

• Suspends execution of the application when it detects violation

conditions. You can choose from several options at this point, including

invoking the debugger in the appropriate context for your application.

• Dynamically monitors multithreading objects (threads, mutexes, and so

on) in real time.

• Provides easy access to object-level statistics and current state

information, including use of resources (for example, the mutexes a

particular thread holds).
