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.

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. 

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);


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).
