Re: No sample file found

[Washington Ratso <JobHunts02@ao...>]

The reason that I cannot open my sample file is that the call to mmap in
odb_open in libdb/db_manage.c is returning MAP_FAILED.  The arguments to
mmap are start = 0, length = 2680, prot = 3, flags = MAP_SHARED, fd = 5,
offset = 0.

Any suggestions why mmap is returning MAP_FAILED?

Oprofile - applicaiton profiling

[Thamizh <tcegrid@ya...>]

Hi All,

I am looking for “application profiling” tool in Linux(RHEL4). My Objective is find out 
the memory usage (including memory used by sub-process and libraries) and Input/Output 
access done by an application on various time stamps.
E.x. - Matlab,Ansys..etc.

Please let me, has Oprofile suits for this need

Regards,
Thamizh

Maybe you can try start oprofile with timer mode in case this processor is
not support well yet.

Re: No samples collected

[Arabinda Verma <arabinda.verma@gm...>]

Thanks Maynard for the reply.

I have tried as you have advised. It is happily taking the detault path
/var/lib/oprofile.

The file system is mounted through the NFS on host. Can this be an issue?
