Slides from May 4th Webinar on Cilk

Hi all,

We did a webinar this morning at 8am Pacific time on changes and new updates in Cilk in the Intel Parallel Composer beta. I am posting the slides here. Let me know if there's any interest to do another webinar on this around 5pm or so Pacific time - I want to see if there's anyone that couldn't attend due to the time that would have liked to attend. Thanks everyone, and I really enjoyed the questions in today's session.

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. 

How can I work with local arrays and threads

Hi All!

I have VS2013+Intel Parallel Studio XE 2015+TBB 4.3

My current code has many functions that has local stack allocations by exampe

void fnc() {

  int arr[1024];

   .............

}

when I started use fnc() in parallel for (it is some form of parallel execution) I got bad concurrent perfomance according to VTune analyser
