Failed to finalize the result: the result you are opening is empty

Event based sampling configurations are not working on my system (pls see details of system setup below).
With EBS, Vtune seems to be profiling for the duration but complains with the following error:
Failed to finalize the result: the result you are opening is empty

Things I have tried so far:

Added the source, binary and include directories as a part of the search directory (clicked on include subdirs as well).

clicked on re-resolve. None of these seem to help.

Machine setup
----------------
CPU: Intel XEON 5690. Events configured for CPU: Intel(R) Xeon(R) / Core i7 980X Processor
running 64-bit version of Vtune amplifier xe 2013. (amplxe-gui.)
OS: Ubuntu 10.04 LTS Linux Kernel version :  2.6.32-40.87.
Kernel modules were rebuilt with pax.ko, sep3_8.ko, and vtsspp.ko

In one of the prior posts in this forum for a similar error, someone from Intel had requested the output of amplxe-cl on /bin/ls. So I thought I would post it here.

amplxe-cl -collect hotspots -r /tmp/r002hs -- /bin/ls

You gave hotspot example, but you had the problem of EBS sampling. If vtune drivers are loaded,

Can you do -

1. amplxe-cl -collect lightweight-hotspots -duration 5 -r /tmp/r003lh

2. amplxe-cl -report hotspots -r /tmp/r003lh/

Regards, Peter

warning: On some systems based on the Intel microarchitecture code name Nehalem / Westmere with C-states enabled, this analysis type may cause system hanging due to a known hardware issue (see errata AAJ134 in http://download.intel.com/design/processor/specupdt/320836.pdf). To avoid this situation, disable all "Cn(ACPI Cn) report to OS" BIOS options before sampling with VTune Amplifier on such systems.

It seemed that you can use event-based sampling for system profiling. CPU time is zero - it did make sense because the processor was not busy then and sample count was limited. You can try to find captured samples (of clockticks):

amplxe-cl -report hw-events -r /tmp/r003lh/

So, now you can try EBS with your application:

amplxe-cl -collect lightweight-hotspots -duration 20 -r /tmp/r004lh -search-dir all:rp=project-dir -- application

What is output? Any error?

Can you use "amplxe-cl -report hw-events -r /tmp/r004lh/" to see report?

It seemed that this problem is target application specific issue (system profiling is OK)

1. Have you tried latest VTune Amplifier XE 2013 Update 5?

2. Have you seen that your target app was running?

3. Is it possible that you can attach this binary? Or go https://premier.intel.com if you wont expose this app on public.
