Profiling of user functions using ITAC

$

Hello,

If I try to get a traceview using "-trace" as a linking-option i get the traceview as I exspected. But in addition I want to get detailed information about the userfunctions which is the reason I started to use "-tcollect" as a parameter for compiling.

I ran the program using "mpirun -strace NAME" (details about the number of processors etc. are provided by the job-system) i got details about every function using "ungroup" - but i didn't get the TraceView (Event Timeline). In the past it worked very well, but then maybe something changed with the operating system (new version of ita, impi, compiler, kernel or something, I don't know).

I cant't use manuell instrumentation with itcpin, because of using linux with the kernel-version 3.x But instrumentation seems to work anyway, because if I'm using "tcollect" I got information about every function...

CFLAG= -tcolellct; LFLAG= -trace

I'm using the intel/12.1.13 compiler, impi/4.1.1 and itac/8.1.1.027

 Thanks for an reply,

Bernhard
