Parasoft Inuse is a graphical tool that helps prevent several common memory problems by displaying and animating in real time the memory allocations performed by an application. Developers often overlook memory problems because memory allocation is difficult to visualize. Inuse gives developers the information they need to ensure that their programs will run smoothly for all users in any conditions.

With Inuse, developers can check a program for memory blowout, fragmentation, overuse, bottlenecks and leaks. Inuse presents users with charts and graphs that clearly illustrate existing and future memory problems. The Heap History report shows the ratio of allocated memory to heap space and is useful in diagnosing memory blowout and overuse. The Heap Layout report displays the dynamically allocated blocks and the free spaces between them, and helps developers in monitoring memory fragmentation. Inuse's Query report shows the amount of memory allocated for different stack traces, and its Time Layout display shows blocks as they are allocated in time sequence.

Clicking a graph displays more in-depth information, including the status of a dynamically allocated block, its memory address, its size, and the stack trace where the block was allocated. The graphs provided by Inuse help developers to:

• see how much memory an application uses in response to particular user events
• compare an application's overall memory usage to its expected memory usage
• look for memory fragmentation to see if different allocation strategies might improve performance
• detect the most subtle memory leaks, which cause problems over time.

Inuse is available with Insure++.
