QNX Releases Multicore Visualization Tools

Part of their Momentics IDE 4, RTOS makers QNX have just released a set of visualization tools for multicore developers. The tools provide a systemwide view of software behavior and performance, letting you identify and isolate complex CPU and resource contention issues, IPC bottlenecks and thrashing, etc. It captures and represents rich data on thread/process activity and states, hardware interrupts, kernel calls, and interprocess comms.

To assist in migration and optimization, the toolkit also gives the developer -- from within the IDE -- very fine control over process deployment, letting you bind processes to particular processors, and by exploiting the QNX RTOS' Adaptive Partitioning feature, move processes around among protected partitions, either guaranteeing them a given CPU level of service, or quickly determining what a process's CPU demands really are, and architecting appropriately.

Momentics IDE 4 is itself a significant upgrade -- the IDE now integrates with the latest version (3.2) of Eclipse, compatible with the recent Callisto release. For more info, visit qnx.com.
