Check if a process is running on the Intel Phi

Hi everyone,

For energy measurement purposes I need to run a program "X" on the Intel phi, that detects when a program "Y" is running in the Intel phi.

Program X runs natively on the Intel Phi (I launch it directly from an ssh terminal logged in the Intel Phi) while program Y is offloaded from the host using micnativeloadex

Here is the code I use in program X, to find if a process is running is a function, that takes in parameter the name of the process:

Windows External Network Bridge

Hello,

Is it possible to setup an external network bridge for the PHI on using a windows based operating system?

This information is not provided in the User's Guide.

I have simply highlighted the PHI and External network adapters and created a bridge.

What are the next steps for this to work?

Do i absolutely need to use Linux for this feature?

Thanks,

Rob

Xeon Phi - Error in installation

When installing the mpss-3.5.1 on CentOS 7 (kernel 3.10.0-229.el7.x86_64), I got an error when issue " micctrl --initdefaults" as below:

[Error] micrasrelmond: [Parse] START_WITH_SECURITY=false invalid config parameter

[Warning] micrasrelmond: Generating compatibility network config file /opt/intel/mic/filesystem/micrasrelmond/etc/sysconfig/network/ifcfg-mic0 for IDB.

Need Phi Optimization Expert to work on new project for Road Material Simulation

Hi,

We require a Intel Phi processor optimization expert to help with optimization FORTRAN code for road material stress simulation. The models have been coded and are working, just need a guru to help move the load off to Phi cards.

Currently it takes 20 days to run a simulation point on a regular Intel i7 2.8 Ghz Quad core notebook processor, we need to get that down to under 40 minutes.

timing is different each time

Hello ,

I wrote a simple application on cpu and I am using offload pragmas for the pieces I want to run on the coprocessors.

Since I am compiling on cpu and I use offloads , I am using :

<code>export MIC_ENV_PREFIX=MIC
export MIC_OMP_NUM_THREADS=120
</code>

in order to specify the threads number.

My problems:

1) Running the code , shows always 40 threads been used.

2) Running again and again the code without compiling , I am getting different time results.
