Profiling tools enhance mission-critical capabilities

Aonix has released the PERC 4.1 platform, a Java virtual machine designed to provide real-time control for mission-critical network infrastructure, military command and control, industrial automation, and commercial telematics. The PERC 4.1 provides a pacing agent and profiling tools that enable developers to achieve accurate real-time control of their applications.

Using a new garbage-collection pacing API, the pacing agent monitors the memory allocation behavior of the application workload and automatically adjusts the timing and ratios of CPU-time increments dedicated to garbage collection activities. Source code for the pacing agent is provided for developers who need to fine-tune it for specialized system needs.

The pacing agent also ensures that no garbage-collection increments are scheduled for times already set aside for execution of application tasks in the real-time workload. In doing this, the pacing agent simplifies development and improves the system's responsiveness to dynamic changes in the system workload.
