target unavailable

[Alexander_Komarov]

Hi, there.

I wanted to run mic_samples that I was sure that Xeon Phi work.

I compiled, but when I am running program, I get message that "target unavailable" and "Offload sections will execute on: Host CPU (fallback mode)".

Samples started
Checking for Intel(R) MIC Architecture (Target CPU) devices...

Number of Target devices installed: 0

Offload sections will execute on: Host CPU (fallback mode)

PASS Sample01
PASS Sample02
PASS Sample03
PASS Sample04
PASS Sample05
PASS Sample06
*** FAIL Sample07 - target unavailable
PASS Sample08
PASS Sample09
PASS Sample10
PASS Sample11
*** FAIL Sample12 - target unavailable
*** FAIL Sample13 - target unavailable
*** FAIL Sample14 - target unavailable
Samples complete

Is it mean that Xeon Phi don't work?

May be, I didn't install all of program for Xeon Phi. 

Thanks, 

Alexander

It's samples from folder "./mic_samples/intro_sampleC".

Also, I try to run samples from folder "./mic_samples/Leo_tutorial/". But I get message 

C/C++ Tutorial: Offload Demonstration

Checking for Intel(R) MIC Architecture (Target CPU) devices...

offload error: cannot offload to MIC - device is not available

The samples are indicating the Xeon Phi card is not available. Did you verify that the card is booted?  Try running the /opt/intel/mic/bin/micinfo command to see if the card is booted.

I run micinfo:

Interesting. Card appears functional.

What version of Composer do you have installed?  (icc -V)

Can you set the environment variable OFFLOAD_REPORT=3, re-run either sample and then post only about the first twenty lines of output into a reply

[Kevin_D_Intel]

Have your source’d the compilervars.sh/.csh script accordingly?

It seems others suffered a similar error as you when not doing so. http://software.intel.com/en-us/forums/topic/391415

[Kevin_D_Intel]

Here's probably the problem. If you happen to manually modify your environment after sourcing the compilervars.sh/.csh and the LD_LIBRARY_PATH does not include /opt/intel/mic/coi/host-linux-release/lib then you will suffer the error you have.

[Alexander_Komarov]

I have installed version of ICC:

Intel(R) C Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 13.0.1.117 Build 20121010.

Thank you for reference on other post. I watched their. 

I ran compilersvars.sh.  But, It is same error.

I entered on the card and checked if coi_daemon is running. And I got the following log:
4888 root 0:00 grep coi

Coi_daemon is not running. What do I do to run coi_daemon?

[Kevin_D_Intel]

The error response you showed in your original post is not what I see when attempting to run the samples with the coi daemon not running. In the absence of the coi daemon the sample hangs after displaying Checking for Intel(R) Xeon Phi(TM) (Target CPU) devices..  and eventually fails with offload error: cannot get device 0 handle (error code 1).

Double check your environment setting for LD_LIBRARY_PATH to ensure the path to /opt/intel/mic/coi/host-linux-release/lib is present in the setting and that the path exists on your system and that similar files (dates/sizes may vary depending on the installed MPSS version) as shown below reside under this location:

[bash]# ls -l /opt/intel/mic/coi/host-linux-release/lib

total 1184

-rwxr-xr-x 1 root root 601641 Dec 17 05:02 libcoi_host.so

-rwxr-xr-x 1 root root 601641 Dec 17 05:02 libcoi_host.so.0[/bash]

To reboot the card and attempt to restart the coi daemon, as root on the host execute:  micctrl -R

micctrl --help will display additional help on all available options.

[Alexander_Komarov]

My problem is fixed. My problem was that when I run compilervars.sh, environment setting don't set. Necessary run this script from file ".profile"(". /opt/intel/composerxe/bin/compilervars.sh intel64"). Default, installer wrote to file ".profile". But I don't have this line in my ".profile", because I deleted this line.

I wrote this line and everything was working.

Thank you so much. 

[Kevin_D_Intel]

Glad to hear everything is working. I'm not sure what installer you are referring to. Ours does not modify the .profile.

[Alexander_Komarov]

Yes, I was wrong, I modified manually this file. But when run compilersvars.sh from ".profile", not necessary every time manually to run compilersvar.sh. So it is convenient.
