I am looking for a performance profiler that is able to profile a C++ library that is being called from a .NET Application.
I tried Purify+ without success (I don't get the calls the COM library) and a few others.

Have you tried the IBM or AMD tools? They're really low level (being made from processor makers!) and so maybe they can profile your component.
Here is a thread that may be of use for you:
Decent profiler for Windows?
xperf might be good.
I know that at a previous job my group used vtune successfully.

I'm looking for a tool for performance analysis and debugging that plots threads context switches, and maybe semaphore states, events, ...
I've used tools like that in the embedded world but I'm now looking for the same in the windows or Linux platforms.
The application I want to profile is a c++ multithreaded application.
Does anyone has a tool to recommend for this ?
For Linux and Solaris the Oracle Thread Analyzer from the Oracle Solaris Studio (it also runs on Linux despite its name) can provide a lot of insight into the performance problems of multithreaded applications. Besides Oracle Solaris Studio is still free.
Intel VTune Amplifier XE (previously called Intel Thread Analyzer) is available on both Linux and Windows.
On Windows you can use xperf tool to collect and plot context switches. It's a free tool, which is a part of Windows Performance Analysis Developer Center. Worked fine for me, see screenshot.
Windows Performance Monitor?
perfmon.exe
I think it's standard on most Windows Platforms and provides information on context switches and much much more.
Windows only I'm afraid though.
Probably this is not the tool you are thinking about, but it is simple, fast and can be useful.
When using GDB, you can type:
info threads
to see information about threads being run. Next you can switch to the chosen thread and print the backtrace to see, where it was:
thread <thread-id>

every one. i am a newbie to cuda. i am wondering that can cuda be used combining with ActiveX technology，
the presented ocx or dll file can be used in webpage，
for example， using cuda can we simulate a fluid particle easily.
if combine cuda and activeX technology ,
we can see fluid particle in a webpage, am i right?
what's more, if there are problems when i simulate lots of particles?
Thank you very much.
I think that if ActiveX could access your GPU on such low level as running your arbitrary CUDA code, it would be a big security risk. If on the other hand, ActiveX could perform some of its computations on the GPU though some higher-level interface, that would be safer, but it is Microsoft who would have to implement it, not you.
A trusted ActiveX control can do anything. So, yes, you could theoretically spin up the CUDA runtime and go to town with the GPU. You would need to distribute the CUDA runtime with the ActiveX control, but everything else you need would already be installed assuming they're using an nVidia GPU. FWIW, distributing cudart.dll is permissable per the EULA on the CUDA Developer Toolkit.
Since, last I read, you cannot statically link against cudart.dll, you would need to distribute that dependency along with your ActiveX control by using a CAB file. Details on creating CAB files can be found here on MSDN. Then again that forum post is from 2008, so maybe newer versions of cudart.dll can be statically linked now... you might want to give it a try.
First and foremost, it runs on the client machine. What means that the client needs to have a CUDA enabled graphics card (nVidia only).
I'm looking for a way to profile my openMPI program in C, i'm using openMPI 1.3 with Linux Ubuntu 9.10 and my programs are run under a Intel Duo T1600.
what I want in profile is cache-misses, memory usage and execution time in any part of the program.
thanks for reply
For Linux I recommend Zoom for this kind of profiling. You can get a free 30 day evaluation in order to try it out.
I finally found graphical tools for mpi profilling
vampir : www.vampir.eu and
paraprof at http://www.cs.uoregon.edu/research/tau/docs/paraprof/index.html
enjoy
Have a look at gprof and at Intel's VTune. Valgrind with the cachegrind tool could be useful, too.
Allinea MAP is ideal for this. It will highlight poor cache performance, memory usage and execution time right down to the source lines in your code. There is no need to recompile or instrument the application in order to profile it with Allinea MAP - which makes it unusually easy to get started with. On most HPC systems and with most MPIs it takes your binary, runs it, and loads up the source code automatically to display the recorded performance data.
Take a look to profiling MPI. Some tools for profiling is mpiP and pgprof.
I'm looking for a free code profiler (performance profiler, not a memory profiler) which works for VSTO applications (specifically Excel in my case, but I gather that if it works for one, it should work for all).
I have tried Eqatec Profiler, but it can't seem to launch the application from the profiler (The Run app button is greyed out, which I'm gathering is because the VSTO application is compiled into a dll which runs in-process with Excel.exe).
If anyone has successfully used Eqatec or another free code profiler to profile a VSTO application, I'd be interested to hear how you did it.
What you're doing should be possible with EQATEC Profiler.
When you're simply instrumenting one or more DLLs then there is no distinct "application to run": you simply have some instrumented DLLs, but the profiler doesn't know in what way you intend to use them.
However, the instrumented assemblies are (along with the runtime-module, EQATEC.Profiler.RuntimeFullNet.dll) always completely "self-contained", meaning that they perform the timing themselves as soon as the methods within them are used. So you simply need to have your VSTO app load the DLL as usual and voila, the DLL will itself start accumulating timing information and start listening for a connection from the profiler with which you can then take snapshots etc.
So to summarize:
Build you DLL and keep the profiler running
Have your VSTO app load the DLL (however you do that)
The profiler and instrumented DLL should now be connected (see the Run-tab)
From within the profiler you can now take snapshots
I hope this helps. If not then let me know.
Have you tried Microsoft's CLR Profiler?
Check out How To: Use CLR Profiler at http://msdn.microsoft.com/en-us/library/ms979205.aspx.
Download CLR Profiler for the .NET Framework 2.0 is available at https://github.com/MicrosoftArchive/clrprofiler.
I have used it with great success many times.
I know the possibilities of basic leak detection for Win32 using the crtdbg.h header, but this header is unavailable in the CE CRT library headers (i'm using the lastest SDK v6.1).
Anyone knows how I can automatically detect leaks in a WinCE/ARMV4I configuration with VC 9.0? I don't want to override new/delete for my class hierarchy, I would prefer ready to use and tested code.
At work (developing WindowsCE based OS + Applications) we have created our own memory manager, roughly based on the Fluid Studios Memory Manager (the link which I found using SO!). I'm pretty sure with a few simple modifications you could adapt it to use on your platform.
Basically it doesn't override new and delete, but instead uses the preprocessor to add extra reporting to it. Then once the program exits it generates an output file of memory leaks.
You want to use either AppVerifier or Entrek CodeSnitch. I've had much better luck getting CodeSnitch working in a short period of time. The caveat there is I don't do a whole lot of WinMo - mostly vanilla CE. I believe there are connectivity issues with CodeSnitch and newer WinMo devices (Platman versus Corecon), but I also believe that Entrek either has a beta or a patch that works for it. My recommendation would be to call Entrek (don't email, they're busy so a call will be your quickest route to info) and only if you find that it won't work, then look into AppVerifier.
I think there is a SourceForge Project for this:
http://sourceforge.net/projects/crtdbg4wince/
If I understand your questin right, it is what you are looking for
