Starting out, with 2 to 12 Phi's

So I bought 2 of the 31S1P's (not yet in use) and am contemplating getting another 10 for a fluid dynamics simulation. I'm trying to figure out how to proceed. I apologize if some of these are stupid questions. I think they're reasonable though as my setup is a bit unique: luckily I have a few 3d printers, in case I need to print brackets or ducts, and a 3600 CFM fan with 15" diameter. Some questions:

problems in offload in fortran modules

Hi all,

I have been trying to run what is called CESM(climate earth system model) and added an offload to one of its Fortran modules.

!dir$ offload begin target (mic)
    print *,'hi this is the offload section'
!dir$ end offload

I performed a successful build. The ar I replaced with the xiar and managed a successful build of the modules.

However while running the final executable i get the following error.

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


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  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.

MPSS 3.4.3 Glibc error: gethostbyname_r returns EINVAL not ERANGE


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


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.

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
