I am running an evaluation of vtune for linux 1.0 on a redhat 7.2 box. I am trying to collect callgraph data on a multi threaded (pthreads) cpu intensive test executable.
running the executable itself exits after 30 seconds. Running the same exe using the following command gets 'stuck', does not return : I get a message Data collection started..., and nothing else.
The command I used :
vtl activity $name -c callgraph -app $app -moi $app run
Are there any limitations on using vtune with multithreaded applications.
Another question : candoes vtune follow forks ?
Thanks in advance.
vtune hangs during data collection
