Hi All,
I ran into a tricky problem when test data race for my codes. The Intel Inspector XE 2013 shows that there is data race in the following calling:
282 !C.. Factorization.
283 phase = 22 ! only factorization
284 CALL pardiso (pt, maxfct, mnum, mtype, phase, n, a, ia, ja, &
285 idum, nrhs, iparm, msglvl, ddum, ddum, error)
But it can still solve the matrix and the result seems correct. How does this data race come from? Would anyone help to check?
There is a "enable-memory-growth-detection" knob in inspxe-cl, how is it possible to use it within the command line?
Hello,
I 'm evaluating Intel Inspector before possibly buying it but up to now I am not successful.
I have a fairly large project (mixed MS C++, Intel Fortran) under VS2013 using OpenMP multithreading. When trying Deadlock and Data Races Analysis I get warning: Inspector does not support the Microsoft OpenMP runtime module .... Where can I get compatible OpenMP modules and how to force their use within my C++ MS project? (I have installed MSVS2012 and Intel Fortran compiler XE). Can I use Intel inspector to inspect VS2012 C++ project?
Hi all,
We are using intel inspector in command line, and producing csv files. We have reports like
"X1882","P9","Kernel resource leak"
Is it possible to know the complete list of rules the inspector checks. Im using intel inspector 2013.
Thanks in advance

I'd like to enable the thread checker option to detect data races on stack accesses. However, I don't see how to do that, and I couldn't find it in the documentation. Could you explain?
I'm a new user and am investigating a data race. I used the "debug this problem" feature and when the debugger stopped, only 1 thread was in the problematic code. So, I couldn't actually see the data race occurring. Is there any way to have the debugger continue until an actual data race occurs (e.g. one thread is reading the value while another thread is writing the value)?
Thanks,

I have code which does the following:
ThreadA():
AcquireSRWLockExclusive(lock);
SharedVar = someVal;
ReleaseSRWLockExclusive(lock);
...
ThreadB()
AcquireSRWLockShared(lock);
var = SharedVar;
ReleaseSRWLockShared(lock);
When I run the Intel Inspector to Locate Deadlocks and Data Races it says that there is read/write data race in accessing the presimably locked SharedVar. Does the Intel Inspector properly work with slim reader / writer locks or should I just discard the issue as a false positive?
I just updated Intel Inspector XE to update 5 version.
One of program I was using hangs. It worked fine on previous version.
CPU: Intel(R) Core(TM)2 Duo CPU
OS: Ubuntu 12.04 with kernel 3.2.0-39.
Used ffmpeg-0.6.3 with input file atttached but it does not stop for more than 24 hours.
The exact command line was: (it also hangs on GUI version)
Has anyone figured out if Intel Inspector will get tricked if memory is deallocated through a different pointer than it was originally associated with? For example if I have a array pointer that I allocate space for, and fill, then I point another array pointer to the original pointer, and deallocate the memory by the new pointer? If I try to deallocate the old pointer I get run time errors, if I don't deallocate it the Inspector reports a memory leak. Is this really a leak? Any help is appreciated.
Hi,
My question pertains to the static analyzer in particular, but also relevant to the thread or memory checker.
I work on a very large scientific code with a number of collaborators at other institutions (national laboratories, universities, etc.). Many of them do not have access to the Intel Inspector. How can I disseminate the results of the code analysis to my collaborators in an intelligible format? The output looks like XML, is there some universal Java reader that is free available, or something that can generate a PDF report.
Thanks in advance.
