MPSS 3.4.3 restart failed when try to add an NFS mount entry to mic0

Hi:

the host running on centos 7 has a new kernel Linux 3.10.0-123.20.1.el7.x86_64,

before mpss installation, I recompiled the mpss module and reflashed the firmware to 391 for mpss 3.4.3,

mic and mpss run well by using miccheck, mininfo, systemctl status mpss. 

NFS server has been installed in the host with:  yum install nfs-utils

rpcbind and nsf service are running well. firewalld and NetworkManger have been stopped. SELinux is disabled.

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 192.0.2.100  netmask 255.255.255.0  broadcast 0.0.0.0
        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.

Calculating “FLOP” using Intel® Software Development Emulator (Intel® SDE)

Purpose

Floating point operations (FLOP) rate is used widely by the High Performance Computing (HPC) community as a metric for analysis and/or benchmarking purposes. Many HPC nominations (e.g., Gordon Bell) require the FLOP rate be specified for their application submissions.

The methodology described here DOES NOT rely on the Performance Monitoring Unit (PMU) events/counters. This is an alternative software methodology to evaluate FLOP using the Intel® SDE.

    The following is a slightly modified test for the GHOST vulnerability:

    #include <netdb.h>
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <errno.h>

    #define CANARY "in_the_coal_mine"

    struct {
      char buffer[1024];
      char canary[sizeof(CANARY)];
    } temp = { "buffer", CANARY };

    int main(void) {
      struct hostent resbuf;
      struct hostent *result;
      int herrno;
      int retval;

    Running OpenCV Computer Vision Programs on Xeon Phi

     

    Hello,
    I would like to know how to run opencv programs by using the intel xeon phi coprocessor card? What are my options? Also, how can i work with the Transparent API released by OpenCV and Xeon Phi ? Has Intel developed any module or support for running computer visions programs on the xeon phi?  Any suggestions or thoughts in this regard will be greatly appreciated.
    Thankyou.

    Trying to create an external bridge

    Hi guys,

    I'm trying to create an external bridge following the users guide from Intel.

    First of all I execute the following command:

    micctrl --addbridge=br0 --type=external --ip=<ip_HOST>

     

    Then, I can see that a file ifcfg-br0 has created and I can see the bridge created with brctl show. Also I attached the eth1 interface to the bridge br0

     

    Then, when I try execute:

     

    micctrl --network=static --bridge=br0 --ip=<ip_MIC0>

     

    I always obtain this error:

     

    [Error] Bridge 'br0' not defined
