Intel® VTune™ Amplifier XE

Profiled program fails to write files

I am a newbie using vtune

I am trying to profile a portion of Quantum Espresso (http://www.quantum-espresso.org/

However, when run under (or attached to) VTune gui, program raises a file handling error signal (38) and crashes. The program runs normally otherwise.  

I have tried AMPLXE_RUNTOOL_OPTIONS="--profiling-signal <another signal>" where another signal is 16, 39 etc. however, this did not resolve the situation.

What might be going wrong?

 

MEM_TRANS_RETIRED.LOAD_LATENCY_GT* unexpected results.

Hi all,

I am trying to use VTune Amplifier (Linux version) to profile memory access latency. I was using it to get familiar with it by profiling a toy program that just loads a big array of data. I use the command line version like this.

amplxe-cl -collect-with runsa -knob event-config=MEM_TRANS_RETIRED.LOAD_LATENCY_GT_32,MEM_TRANS_RETIRED.LOAD_LATENCY_GT_64 ./load The result I get is the following.

MPI program profiling on Xeon phi error

Hello, I am using Vtune to profile my MPI progam which involves two ranks (one on Xeon and the other on Xeon-phi)

I have set up a NFS mount for shared libraries and the path for vtune is visible from MIC root

below is the command i use to run hotspots report on xeon and on mic, 

mpirun -host localhost -n 1 /opt/intel/vtune_amplifier_xe_2013/bin64/amplxe-cl -quiet -collect hotspots -result-dir exon ./hello.xeon : -host mic0 -n 1 /opt/intel/vtune_amplifier_xe_2013/bin64/amplxe-cl -result-dir /root/mic_vtune -collect -quiet knc-hotspots ~/hello.mic

How to choose the (correct) CPU for profiling?

I'm quite new to vTune profileing so I'm guessing this is a simple question: When  choosing the analysis type, I can see for the event details: "Event configured for CPU: Intel(R) Xeon(R) E5 processor". But the processor for the profiled hardware is Intel Core i7-3930K. Why does it say that it is a Xeon processor and is the test metrics collected inaccurate due to this?

"LLC Load Misses Serviced By Remote DRAM" seen on Xeon X5650 with only 1 CPU?!

Hi,

after doing a Nehalem General Exploration of my code, the results show several "LLC Load Misses Serviced By Remote DRAM" events. I have measured this on a Xeon X5650 platform with only 1 CPU (6 cores, 12 incl. hyper threading), so my question is: how can there be a "remote" DRAM if there is only 1 CPU? As far as I know, "remote DRAM" means a piece of memory which is attached to another CPU and thus requires a QPI transfer.

Level 2 data cache event counters?

Below is a list of all the event counter I have available on my Ivy Bridge CPU. It contains "L1D" cache event counters, but there are no "L2D" counters- only "L2". I was under the impression the L2 cache is split in to data and instruction caches. 

(I have read the descriptions of the below event counters and the "L1D" says "L1 data cache" and the "L2" says "L2 cache", implying it is not specific to the data cache).

What event counters should I use to measure data cache misses for L1/L2/L3, ignoring instruction cache misses?

Seems not detect end of apllication. Report: BUG! Please contact the technical support.

Hello,

I'm just taking a look at the VTune Amplifier XE and following the tutorial "Find hotspots" with my application.

After pressing the "Start" button I saw my debug messages at the terminal and the application reached its end but the VTune seems not to detect it and shows no reaction any more. If I kill it, it shows:

The data cannot be displayed: there is no viewpoint applicable for the data

I have just downloaded the trial of vTune Amplifier XE 2013 r.16 and have tried to do a basic hotspot analysis from with VS 2012.  Unfortunately all I get is the error: "The data cannot be displayed: there is no viewpoint applicable for the data".  I have attached the output below.  I think I have the project options setup correctly. What do I need to get it working?
 

Thanks

 

VTune on the Intel Galileo Board (Quark)

Hello,

has anybody managed to run VTune on the Intel Galileo Board (remotely)?

I got stucked trying to build the kernel modules. Started with 'meta_clanton_v0.7.5' but I think the kernel is not correctly configured. There sme messaages about 'CONFIG_MODULES' etc. not beeing set. Finaly 'cylcles_t' is not defined and compiling stops.

Any help is appreciated!

Greetings

Error while building sampling driver and Error while building power driver

Hi,

I receive these messages, during installation of Intel Cluster Studio XE(sp1: l_ics_2013.1.046):

Error while building sampling driver, see /tmp/amplifier_sampling_build_13.03.14.17.50.07.log for details

Error while building power driver, see /tmp/amplifier_power_build_13.03.14.17.50.07.log for details

 

Logs are attached, but they don't help me much.

 

I am using this kernel: 2.6.32-431.5.1.el6.x86_64 (CentOS 6.5)

 

How can i build these two drives correctly, after installation?

 

Thanks in advance
