Connecting coprocessor to bridge to communicate with internet

Hello,

I am running Ubuntu 14.04 with a xeon phi 31s1p and I have been trying to set up a bridge so that I can have the phi access the internet, although I have been having a lot of trouble and can't seem to figure out what's wrong. I'm pretty sure the bridge itself is fine but the phi can't connect to it, anytime I try and use the simple command for it to connect to the bridge it gives this:

/var/mpss/mic0/etc/network# micctrl --network=static --bridge=br0 --ip=172.31.1.1
  [Error] br0: Failed - required brctl command not installed

How to build boost library for Xeon Phi on windows.

I have tried to build boost library for xeon phi on "Windows" with Intel C++ Composer XE 2015, but it failed.
I found following article, but this is for Linux...
https://software.intel.com/en-us/articles/building-the-boost-library-to-...

Does anyone know the procedure?

Thanks,

Why it shows COI_ERROR

I am running Intel Optimized MP LINPACK in a new server with 1 Intel Xeon Coprocessor 
I run ./runme_offload_intel64 in benchmarks/mp_linpack/bin_intel/intel64 but it shows:

Why it shows: mic03 : COIProcessCreateFromFile result COI_ERROR

What's the reason?(MPSS is running).

Thank you for your answer.

Direct Access to PHI Via Port Forwarding

 

Good morning:
I have a question and before I get too far I want to see if there is a might have a solution.

I want to forward ip comm from an incoming port like 192.168.1.1:5000 to the internal  mic address 172.31.2.254:22

So that i could ssh from a networked computer directly to the mic.

Such that if I let’s say ssh to nesbphi1.ndc.nasa.gov:5000 it redirects me to the mic0. 

I have tried the port forwarding and i just land at the remote host machine.

I am running MPSS 3.4 and centos 7.

 

Thanks in advance

Intel MPI 5.0.2.044 and Windows firewall on localhost

Hi everybody,

We run mpiexec on Windows 7 on multiple network installations of our product in the following manner:

mpiexec.hydra.exe -np x -localroot -delegate -localonly -localhost 127.0.0.1 one_path_to_EXECUTABLE

The problem is with the windows firewall (which is executable path triggering) and alerts, because mpiexec.hydra.exe and pmi_proxy.exe do a listen on 0.0.0.0:port.

Is there an option / environment variable available to tell mpiexec.hydra only listen on 127.0.0.1 instead of all available interfaces if we run it only local on one workstation.
