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.

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. 

Dynamic Languages take over the internet

What would happen if you were hauling a trailer down the road, and suddenly you realized that the trailer you thought you were pulling passes you on the highway. (Which I guess can actually happen, I just saw a video capture of this exact disaster, happening to a trucker). You might not feel kind of blind-sided!

This is kind of the way I feel when a technology trend sneaks up on me and suddenly I feel like I'm way behind the curve.

iconv issue

hi all,

 

I'm trying to build something for the Phi that depends on iconv; the library routines are present , but the following application fails when run on the Phi:

#include <stdlib.h>
#include <iconv.h>

int main () {
  iconv_t cd;
  cd = iconv_open("latin1","UTF-8");
  if(cd == (iconv_t)(-1)) exit(1);
  iconv_close(cd);

  exit(0);
}

if I build this using "icc -o iconv_test iconv_test.c" and run it on the host it return no error (exit code 0).

Xeon Phi and offload from MATLAB MEX file

Hello,

I am having a really hard time figuring out how to use the Xeon Phi offload mode from within MATLAB MEX files under Linux. I have managed to force MATLAB to use icc for compilation and verified that the mex files run fine. The problems start when using the offload pragma - as far as I can tell, nobody has tried that yet and I suspect this is some (fixable?) issue with libraries. Can someone here help me with this?

Consider the following simple code
