Stack Overflow works best with JavaScript enabled. Collecting Concurrency Visualizer data requires the collector, Visual Studio or the command line tools, to be running with administrator rights. Using the same program I wrote to show the Concurrency Resource Profiler , which does sync block and mutex acquisitions on two threads, I can show you the concurrency analysis. If you click on a thread, you are able to view the contentions only for that specific unit, as well as see the call stack for a contention — this might help you in determining where the possible source might be and where a lock should be in place. As it says at the top of the view, if your process threads are moving between cores, you may have a performance problem. Notice there are many small execution green segments. Notice that not only the application performance is graphed here, but also the client system performance.

I couldn’t determine which process or service on my computer started those ETW sessions.

Here comes the fun part: Profiling this application with the Concurrency Visualizer will show something like this:. The Current stack tab tells us that thread is unblocked by This means that some variable or method names are exposed to the developer or user who attached the debugger to the process in test, in order for the person who debugs the code to directly see what the source of the error is.

As it says at the top of the view, if your process threads are moving between cores, you may have a performance problem. I always monitored thread count on the profiled process with procexp, restarted several times, nope. Now get out there and fix your problems with Concurrency Visualizer! List all Data Collector Sets: The last piece of analysis I want to discuss with the Paraffin program run is the Profiler Report tab.

Asked 6 years, 4 months ago. The call stacks are captured on the ETW events, which is why thread has the link line in the middle of its execution block. NET or native development.

Like Concurrency Resource visaulizer, turning on Concurrency Visualizer profiling is very easy. WaitOne method blocked on the mutex.

I have no idea why. The unblocking stack, on the other side displays the opposite — the thread that unblocked the selected thread from the declared state and the associated calls. Directly connected to this statistical indicator is the Cores view. Convurrency current stack gives even more details about the given thread state: Over a million developers have joined DZone.

What we need is a tool that lets us gather all this amazing information from ETW and relate it directly to our code. In all those cases trying to figure what files were being accessed at startup was nearly impossible. CV started to dislike procexp. The main thread could be blocked for many seconds, or even forever!

So, stusio show an example, here is how I modified the thread creation process:.

Free DZone Refcard Java As Studi described, Paraffin is a tool that you use to recursively scan a directory tree for files and builds up an XML tree of those files, which, in the big scheme of things, is a very simple tool. This is a great view to see everything going on with your code visyal the various types of activity. Since I am creating threads via ThreadPoolthe thread names are automatically generated.

That means they are waiting on handles or other synchronization events in kernel mode and not doing anything. The selected area, in bright red, is where thread is blocked waiting on the mutex. Xtudio Paraffin does is dig through a directory, gets all the files in the directory, and build an XML file of that data.

It should be clear from this result and the picture visualixer the LongRunningWork function should be executed on a separate worker thread.

To avoid this, I could introduce a lock inside my testing method, so that the final indicators would look more like this:. Ideally, the UI thread will be able to wait on UI messages almost all the time because it is not engaged in complex processing.
