We installed a NVMe SSDs in knl00 at /nvme0n1. This is the same SSD model thats in Theta: Samsung SM951 128GB NVMe SSD - MZVPV128HDGM. Please don't be bashful about wearing this SSD out. I'd like to see what it takes. Ben

Re: [JLSE-Intel-NDA] Power measurement on KNL

Tania, I am also interested in taking power measurements on KNL. There is some information on this in Chapter 19 of the Xeon Phi Processor High Performance Programming book (link <https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uac…>). The only method given in the book which appears to work is to use perf, i.e.: > perf stat -a -e "power/energy-pkg/" <executable> I would be interested in using ipmitool or turbostat, though I'm not yet sure how to do so.

Re: [JLSE-Intel-NDA] MXNet install depends

See /soft/compilers/llvm/ for Clang. I haven't tried it yet but Spack (http://spack.readthedocs.io/en/latest/getting_started.html) is supposed to be something like Homebrew for HPC systems. If you can get most of your dependencies there, it would at least automate the process, even if they still need to be compiled from source under the hood (I'm not aware of Spack using bottles ala Homebrew).

Re: [JLSE-Intel-NDA] Using VTune remotely on the Phi

Interesting. The events listed in the various templates in the GUI are not necessarily all the events that are available. -michael From: Will Boyd [mailto:[email protected]] Sent: Monday, January 09, 2017 10:13 AM To: D'mello, Michael <michael.dmello(a)intel.com>; Hammond, Jeff R <jeff.r.hammond(a)intel.com>; intel-nda(a)jlse.anl.gov Subject: Re: [JLSE-Intel-NDA] Using VTune remotely on the Phi 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.

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.

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-pr…> 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.

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-8…>, 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.

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.

Re: [JLSE-Intel-NDA] Using VTune remotely on the Phi

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. -michael From: Will Boyd [mailto:[email protected]] Sent: Monday, January 09, 2017 9:37 AM To: D'mello, Michael <michael.dmello(a)intel.com>; Hammond, Jeff R <jeff.r.hammond(a)intel.com>; intel-nda(a)jlse.anl.gov Subject: Re: [JLSE-Intel-NDA] Using VTune remotely on the Phi 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-pr…> 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?

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.
