Knight's Landing + Java

Dear Intel Staff,

I just got to know some details of your great presentation of Knight's Landing (KNL) at Hot Chips this year. Information about KNL on the website is still sparse. From your slides I understand that there will be a version of KNL that is socked and can be used as a primary CPU in a rack. However, this raises quite some questions that I cannot find satisfying answers.

Exposing processor features to dynamic languages

It always causes me exquisite pain to see someone laboriously copying down a long number from their computer screen, just to type it in to another window or application. Doesn't it for you?

After all, doesn't everyone know about the cut-copy-paste keys? I'm talking about selecting text with your cursor and using control-C for copy and control-V for paste.

common block problem in openmp Fortran

my code is:

 program
 ...
 ! Loop which I want to parallelize
 !$OMP parallel DO
 I = 1, N
 ...
 call FORD(i,j)
  ...
 !$OMP END parallel DO
 end program

  subroutine FORD(i,j)

How to I determine at runtime what vector instructions are being used when compiling with -ax

In a few weeks, we will have another generation of Intel HPC system.  We will have systems that support SSE4.2 (Nehalem, Westmere), AVX (SandyBridge, IvyBridge), and CORE-AVX2 (Haswell) optimizations.  Since the compile nodes are being upgraded to Haswell as well, I want to tell the users to specify something different than -xHost when using Intel Fortran so binaries can be backwards compatible and run on any of the clusters.  I planned to tell the users to use -xSSE4.2 -axCORE-AVX2,AVX.

 

My questions are:

 

Questions about SCIF Driver

I have a system with 2 PHI cards installed running on redhat 7.0. I am able to run code on the cards as pure offload and I can ssh into the cards. I am trying to get symmetric mode to work.

1) Does symmetric mode require OFED, or is OFED only required when there is a physical Infiniband card?

2) What are the proper steps to verify that the SCIF driver is properly loaded? mic shows up as a driver but there is no indication of anything named SCIF.
