RTOS scheduling visualization
Gain insight into your application through scheduling visualization
Understanding your application’s scheduling behavior can help you troubleshoot scheduling issues. RapiTask automatically collects information during program execution, presenting this data so you can follow the events that occurred in the test run.
Providing a timeline of the tasks that ran in your system, a wealth of charts and statistics, RapiTask lets you analyze your system’s scheduling behavior in-depth.
Locate rare timing events that need attention
RapiTask makes it easy to find rare timing events such as priority inversions in your system so you can fix them. By following your system’s tasks throughout execution, you can easily locate rare timing events, which can be visualized easily for example by color coding tasks according to priority.
You can also verify that your highest priority tasks aren’t pre-empted at a glance by using fragmentation charts and statistics.
Identify bottlenecks in your application by analyzing capacity issues
Bottlenecks in critical software can slow the system down or even cause it to fail as timing deadlines are missed. By letting you view the CPU utilization of each task in your system throughout your software execution, RapiTask helps you identify bottlenecks so you can fix them.
Compare scheduling algorithms from different RTOSs
While there are many vendor-specific scheduling visualization tools, these are often only compatible with a single RTOS. RapiTask lets you understand your system’s scheduling behavior through a common framework no matter which RTOS you’re using.
This means less time learning new tools and more time testing and resolving issues.

Frequently asked questions
Which languages does RapiTask support?
RapiTask supports C, C++ and Ada projects, including mixed-language ones.
How do I learn more about RapiTask?
You can request a trial version of RVS, which includes RapiTask. You can also arrange a demonstration, where a member of our team will work with you to show the benefits RapiTask can offer you.
If you’re interested in RapiTask in academia, you can search for it in the academic press.
What is RapiTask?
RapiTask is the leading tool for task-level scheduling analysis of critical software.
Used globally in the aerospace and automotive industries, it reduces the cost of understanding software scheduling behavior and troubleshooting scheduling issues.
As part of the RVS toolsuite, it forms part of a software verification solution that also includes tools for functional testing, structural coverage analysis and worst-case execution time analysis.
How does RapiTask work?
RapiTask provides an RTOS-independent tool for visualization and exploring the scheduling behavior of embedded systems, and rapidly diagnosing and identifying potential problems.
It lets you visualize scheduling behavior across threads and processor cores, and reports response times from your system.
Which host operating systems can RVS be used on?
RVS tools support Windows 7 or newer, Windows Server 2008 R2 or newer, and a variety of Linux distributions including Ubuntu and Red Hat.
RVS tools can be used on projects with unsupported operating systems by using a clone integration to split the process and delegate parts of it to the unsupported machine.
Which hardware architectures do RVS tools support?
RVS tools can be integrated to work with almost any embedded target. Our engineers can work with you to determine the optimal strategy for integrating the tool with your target, even for multi-core architectures. For more information on the hardware architectures we have integrated RVS tools with, see our support specification.
Can I use RapiTask with my build system?
RapiTask can be integrated to work with almost any compiler and target hardware. Our integration service promises to deliver a robust integration of RapiTask into your build system.
How is my data presented?
RapiTask displays data in two applications, the RVS Project Manager that is shared with all RVS tools, and an application specifically designed to display task scheduling information. You can synchronize the two applications to ensure that you can easily identify specific timing events in your system.
Can I use RapiTask to analyze the behavior of multicore architectures?
As with all RVS tools, RapiTask supports data collection on multicore architectures.
RapiTask is a component of the Rapita Systems Multicore Timing Solution, which analyzes the timing behavior of multicore systems and is suitable for DO-178C/CAST-32A compliance.
Why do I need RapiTask when I have tools from my RTOS vendor?
RapiTask is OS-agnostic so you can keep the same visualization and metrics if you change OS, and you can use RapiTask results as a point of reference to compare operating systems.
Additionally, you can capture and display custom events not related to the operating system (for example ARINC 429 messages) and display them in the trace.
Can I only use RapiTask with RapiTime, or can I use RapiTask as a standalone tool?
You can use RapiTask as a standalone tool with either automatic or manual instrumentation.
If I have RapiTime, do I still need RapiTask?
RapiTime abstracts away from the OS tasking model and only reports the execution time of a task as if it were the only thing running on the CPU. If you are interested in the response time of your code, or the interaction between tasks and your OS, you'll need RapiTask.
How does RapiTask show OS events such as inter-process communication (semaphores, messages). timers, hardware I/O etc?
RapiTask is OS-agnostic; as with all Rapita tools the integration with the operating environment needs to be customized. If we can get information about items of interest from the OS we can add ‘user events’ to a RapiTask trace.
How large a code base can RVS tools handle?
RVS tools are designed to handle very large code bases. Because of the efficient algorithms used by RVS tools, there is no fundamental limitation to the number of lines of code that RVS can process, and our RVS tools have been used on projects with millions of lines of code.
How are RVS products licensed?
We offer both “Node-locked” and “Floating” licenses, and a license server to support use of our tools in your specific development environment. Floating licenses follow the “Enterprise” model, meaning that you can use our tools across geographical boundaries and different projects and users.
For more information on our licensing models, see our RVS licensing FAQs.
What happens if I encounter an issue while using an RVS tool?
All RVS licenses include access to our dedicated in-house support team, who will work with you to provide a rapid fix to your issue. This is a critical part of our vision. During 2016, we responded to 97% of new support requests within one working day, closed 56% of these within 3 working days and 91% within 20 working days. We also inform our customers of known issues via our website and email.
How do you support RVS users?
We provide an extensive set of RVS documentation with each of our products, and offer training courses guiding you through the most effective use of RVS tools. All our users can benefit from privileged access to our website, which includes downloads for new product releases.
