Lack of Ivy Bridge support in current VTune

Slide 9 of https://software.intel.com/sites/default/files/Using_Intel_VTune_Amplifi...

shows a Sandy Bridge/Ivy Bridge Analysis category of pre-configured profiles.  However, with the XE2015 Update 2, there are categories for Sandy Bridge and Haswell, but none (besides General) which work for Ivy Bridge (see attached).   Which version of VTune, if any, is recommended for Ivy Bridge Memory Access analysis on

CPU compatibility with Xenon Phi ?

I am having hard time finding information on CPU compatibility with Xenon Phi's, if there is any.

Will the Xeon Phi 31S1P and the MPSS 3.4 work with i7 4820k ? Is there any restriction on CPU ?

Also, the Read me file for Windows of the driver says that the currently supported OS are:

Microsoft Windows* 7 Enterprise SP1 (64-bit)

Microsoft Windows* 8/8.1 Enterprise (64-bit)

Microsoft Windows* Server 2008 R2 SP1 (64-bit)

Microsoft Windows* Server 2012 (64-bit)

Microsoft Windows* Server 2012 R2 (64-bit)

Is there any way to link against an older version of MPSS

Hi Folks, 

I'm seeing some very strange performance with a computational chemistry code (CP2K) that I've previously benchmarked extensively on the Xeon Phi. I'm running in native mode for these tests. 

Since our cards were upgraded to MPSS version 3.4.2 my mixed mode MPI/OpenMP version of the code is running 10-20 times slower than it used to. 

sparse pblas?

Hello everyone,

I am trying to use MKL to solve sparse matrix multiplication (i.e. C=A*B) in parallel. I found there is sparse blas for sequential code but I am wondering if there is a parallel version of it.

Thanks,

Likun

 

Problem with hardware counter analysis

I am trying to understand the behaviour of programs by running the hardware counter analysis. I tried running the program with multiple size datasets with a finite set of counters to be measured. But to a great surprise, vtune measures most of the counters and dumps in the log. But for few runs, it only measures very few counters among the same set. It also drops down the runtime of the application to a great extent. Is this behaviour normal or its some kind of a bug?

 

Xeon Phi 31S1P 270W vs 300W

Hi,

System: Ubuntu 14.03, MPSS 3.4.1, 31S1P

When I run micinfo it display "Product 300W Passive CS" instead of 270W as product description. Is it a "feature" or a bug?

  Thanks,

svml_* / libirc in Composer XE 2015 update 2 on Windows

I have updated my Composer XE 2015 installation to the update 2 on a Windows PC, and it seems that svml_* and libirc libraries are gone. (In case my upgrade went wrong, I also did a repair of the installation.)

However, those libraries are still needed by MKL.

Any idea was is going on? Any suggestion on how to proceed?

ICE with icpc 15.0.0.090 on std::enable_if

I have a problem with compiling code that works fine with gcc 4.8.1 or clang 3.5. At first, icc refused to compile it claiming (incorrectly) that my code had more than one instance of an overloaded template function (where I was using SFINAE). When working around this bug (by replacing a single template function with several overloaded non-template functions), I got:

/cm/shared/apps/gcc/4.8.1/include/c++/4.8.1/type_traits(1766): internal error: assertion failed: lower_constant: bad kind (shared/cfe/edgcpfe/lower_il.c, line 5804)
