Security Advisory: Intel(R) MPSS affected by Shellshock bug


Recently there was a critical vulnerability exposed in the GNU* Bourne-Again Shell (Bash), the common command-line shell used in many Linux*/UNIX operating system.   This vulnerability also affects the operating system used for the Intel(R) Xeon Phi(tm) Coprocessor.  

Intel® Xeon Phi™ Coprocessor - ROADMAPS and Cluster BKMs

Attached to this thread is a PDF containing :

 - Guidance/communication on recent changes (and things Intel is considering) to make Cluster administration more straightforward

-  Calls out some tips and tricks which may be useful (especially with the latest MPSS release) 

- MPSS roadmaps (not cluster specific, general for all):   release cadence, OS support, OFED roadmaps, and features planned for MPSS 3.3


If you have feedback or concerns (on OS support, etc.), please let us know!

Intel(R) Xeon Phi(tm) Coprocessor -- Cluster training - call for demand!

Intel is evaluating to offer a 4 hour web-based basic tutorial covering the fundamental principles of how to integrate an Intel Xeon Phi coprocessor into a Linux based cluster.

During the course each attendant would have remote access to a Linux server and be able to do each step as shown in the outline below.  The course will be given free of charge. Requirements are an Internet connection, a web browser, and Putty.   We are settling on the sharing technology we will be using, and will publish that at a later date.

Troubleshooting HOWTO: Bad hardware? MPSS? Configuration?

Are you having problems with your hardware (Cannot see your Intel(R) Xeon Phi(tm) coprocessor?  Sporadic accessibility?) or with the Intel(R) Manycore Platform Software Stack (Intel(R) MPSS) running reliably?

Attached to this post are PDF "flowcharts" that explain how you can troubleshoot the problem (note:  Both Linux and Windows flowcharts are available), and shows what information you will want to collect if you need to escalate your issue to your OEM provider or Intel.

What collateral/documentation do you want to see?

Do you have questions that you are not finding the answers for in our documentation?  Need more training, source code examples, on what specifically?   Help us understand what's missing so that we can make sure we develop documentation you care about (what is important, and what is nice to have)!   Thank you

FAQS: Compilers, Libraries, Performance, Profiling and Optimization.

In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.

infiniband connection host-mic and mic-mic

Hi, I'm trying to set up infiniband connection between host and mic, mic and mic. Host is showing this on ifconfig:

mic0:ib: flags=67<UP,BROADCAST,RUNNING>  mtu 64512
        inet  netmask  broadcast
        ether 4c:79:ba:20:06:63  txqueuelen 1000  (Ethernet)

and two: mic0 and mic1 interfaces.

I have two coprocessors installed.  I can run ib_read_bw between host and mic0, but not host and mic1 or mic0 and mic1.  Getting error:  

Received 10 times ADDR_ERROR
Unable to perform rdma_client function.
