Intel® VTune™ Amplifier XE

Licensing issue with amplxe-cl

I am able to use the VTune GUI without issue, and am also able to collect using amplxe-cl from the command line.  What I cannot do is generate a report from the command line.  amplxe-cl -report hotspots -r <results dir> produces:

amplxe: Error: 0x4000001f (No valid license) -- Cannot connect to the license server. Make sure your license daemon process is running, the used port@host or license file is correct, and the port or hostname in the license file has not been changed.

[vmlinux] [no call stack information]

Hi,

Currently, I'm using Advanced Hotspots to analyze the executable file resulting from compiling C source code.

However, from the analysis, it showed that most the time was spent in [vmlinux]. And, there is no call stack information displayed when I double click the function [vmlinux] in the Summary window. I'd made link named "vmlinux" to vmlinux-3.13.0-48-generic, which is the debug-info needed.

FYI, my OS is Ubuntu 14.04.2 LTS Trusty Tahr.

 

Apart from that, I encounter 2 warnings when I run the analysis:

VTune 2015 collection failed

Hi,

We are trying to optimize performance using  the VTune Amplifier 2015, it always returns collection failed.

The target machine is RHEL 6.3 with Linux kernel 2.6.32

We use in the trial mode

amplxe-cl -collect hotspots -duration 10 -target-pid 13649

The following is the error output:

amplxe: Collection detached.

amplxe: Fatal error: Unknown critical error

amplxe: Collection failed.

amplxe: Internal Error 

met some problem using advanced-hotspots

Hi all,

We met some problem using advanced-hotspots.

amplxe-cl -collect advanced-hotspots -r max_test_2_11 -duration 30 --target-pid 6859
 amplxe: Error: Cannot enable Hardware Event-based Sampling: problem with the driver (sep*/sepdrv*). Check that the driver is running and the driver group is in the current user group list. See "Building and Managing the Sampling Driver" help topic for further details.

Maybe some driver is missing. We are OK without Hardware Event-based Sampling.

Package update on the target is required

Hi,
I am trying to remotely collect data on my target machine using the VTune Amplifier. The passwordless connection is already set up. When I try to connect to the remote machine, this is the message I get:

Detected VTune Amplifier build #367959 on the target system at ..path/to/vtune/installation... with the build #393444 on the host. Package update on the target is required. Amplifier cannot detect remote machine configuration.

Ivy Bridge, counting cycles stalled due to LLC cache load misses?

Hi,

On Ivy Bridge there are the following counters:

  • CYCLE_ACTIVITY.CYCLES_L1D_PENDING
  • CYCLE_ACTIVITY.CYCLES_L2_PENDING
  • CYCLE_ACTIVITY.CYCLES_LDM_PENDING

but no CYCLE_ACTIVITY.CYCLES_LLC_PENDING. I have performed some profiling and my results suggest you cannot just subtract the first two counters from the third counter, to get the LLC value. There are three counters for the number of times there is a cache miss, but I want to know the effect of stalling.

Prroblem with analysis on Intel Xeon Phi

Hello,

I'm trying to analyze simple serial aplication (matrix multipication) dedicated for Intel Xeon Phi coprocessor using VTune. I created native aplication, using -mmic flag and next copy it to mic0 using scp command. Next I ran analysis as shown in the link below :

https://software.intel.com/en-us/articles/how-to-analyze-xeon-phi-coproc...

PMU resource(s) currently being used by another profiling tool or process

The following command

mpirun -n 4 /opt/intel/vtune_amplifier_xe/bin64/amplxe-cl -collect-with runsa -knob event-config=FP_COMP_OPS_EXE.X87 -result-dir /home/fabrizio/Desktop/testt/ -- /home/fabrizio/Desktop/test

returns error in subject.

I tried a solution explained in an another post (./insmod -sep3 -r), but it seems not to be my case, because with ONE process I don't have error about PMU resource(s), but an error about "Failed to create a tb6 file".

How could I solve?

Thanks!
