I certainly understand that the programming guide may have fallen behind the times. However, some of the events given in the guide may be collected even though they aren't included in the VTune GUI. The following worked for me to collect two such events: amplxe-cl -collect-with runsa -knob event-config=MEM_UOPS_RETIRED.L1_MISS_LOADS,MEM_UOPS_RETIRED.ALL_LOADS ./a.out Perhaps VTune still support some (deprecated) events in the guide, or simply doesn't list all possible events in the GUI.

You are very welcome. Looks like, I will have to sync with the sys admin for JLSE to properly resolve the issue you are seeing.

It can (& does) happen that different versions of the same hardware may support slightly different sets of events. The folks on the VTune team try to support as many events as possible, but they do not always get to all of them.

I will have to look at Chap 14 more closely, but my guess is that even in the short time between when the book was written and now, the event set has changed.

Thanks Michael, I appreciate your help and hope you find a workable solution.

Also, I find it interesting that many of the counters in the Intel Xeon Phi Processor High Performance Programming <https://www.elsevier.com/books/intel-xeon-phi-processor-high-performance-programming/jeffers/978-0-12-809194-4> guide (Chap. 14) are not available in VTune. In particular, when I select "Intel Xeon Phi coprocessor" in the VTune GUI, and then look at the available events under the "Analysis Type" tab, I do not see the events listed in the guide. Is there a reason that the counters in VTune don't correspond to those in the programming guide?

If this works, we can do a similar thing with hpc-performance & memory access. I will send you those command lines.

Still checking on a better solution.

Michael,

I am running on the machine named "KNL" - in particular, I most recently ran on node "knl05".

I ran the command you suggested and the following is the output:

$ amplxe-cl -collect-with runsa –analyze-system –duration 5

amplxe: Collection started. To stop the collection, either press CTRL-C or enter from another console window: amplxe-cl -r /home/wboyd/r000runsa -command stop.

While I sort out my login problems, could you try:

Send me the output of this command.

Also which JLSE KNL are you using?

For some reason, "hpc-performance" is not provided as an "Analysis Type" in the GUI when the Intel Xeon Phi is selected as the "Analysis Target." Nevertheless, I selected "memory-access" as an "Analysis Type" and produced the following command line:

amplxe-cl -target-system mic-native:mic0 -collect memory-access -knob analyze-openmp=true -app-working-dir /home/wboyd/ecp-benchmarks/pin-cell -- /home/wboyd/openmc/build/bin/openmc

When launched from a KNL node on JLSE, this results in the following error:

amplxe: Using target: mic-host-launch:mic0

amplxe: Error: Amplifier cannot detect Intel Xeon Phi coprocessor configuration.

amplxe: Error: Amplifier cannot detect Intel Xeon Phi coprocessor configuration.

Thanks in advance for any advice on how to sidestep this issue.

Will,

From what I can tell, the system you are on seems to be configured to use the Linux “perf” collector by default. For “hpc-performance” to run with this collector, you will have to configure “perf” in system wide mode. The error you were seeing seems to be related to this.

The following page provides some details: https://software.intel.com/en-us/perf_collection_from_lin (I have listed the relevant section below).

Unfortunately, the information provided will not help directly (unless you have root privelages on jlse).

One workaround is to configure the analysis in the gui & output the command line (click on the “Command Line” button). You will have to check the “Use –collect with action” box to get the command line you need. This approach should work, but as you will see the command line is complicated. You can certainly try this, but I believe there is a simpler workaround. More on this shortly.

Regards

-michael

PS: The relevant section on the page is:

*NOTE*

· For uncore events collection, configure Perf to run in the system-wide mode by setting the /proc/sys/kernel/perf_event_paranoid value to 0 or less (root privileges are required).

· For the kernel modules resolution <https://software.intel.com/node/84ddf2a4-d4a6-4027-92e3-dce7b0fd7044#GUID-8C1ADD41-432E-4FEA-A5B3-99022E32C258>, make sure you have enough permissions to read kernel symbols information from the /proc/kallsyms file.

Perf-based driverless collection can be used for running Advanced Hotspots, General Exploration and Custom event-based sampling analysis types on Linux and Android OS. If the uncore events support is available on the system, the VTune Amplifier may also use the Perf collection for Memory Access, HPC Performance Characterization and General Exploration analysis types with the *Analyze memory bandwidth* option enabled.

Michael,

Yes, that command works, along with "concurrency" and "locksandwaits". Only the "hpc-performance" and "memory-access" fail on KNL.
