Xeon PHI library

Donato_P_ — Thu, 23 Jun 2016 14:06:38 GMT

Hi,

I compiled my code for Xeon PHI but I get this output from :

ldd mycode

linux-vdso.so.1 => (0x00007fff585c8000)

libmpifort.so.12 => not found

libmpi.so.12 => not found

/lib64/ld-linux-k1om.so.2 (0x00007f3e6f885000)

I tried laso to export the correct path inside the LD_LIBRARY_PATH but without success

it doesn't find any new libraries

Regards D.

Copy these MIC libraries to

Copy these MIC libraries to the card, or even better, mount the installation directory of the Intel Software Tools on the card.

Hi I did , I used nfs to mount the /opt/intel on the mic and I also tried to copy the libs 1 by 1,

but it doesn't work and when i try to copy the /opt/lib by nfs on the mic I get the folder but it is empty

any idea?

In more detail, you must

In more detail, you must either copy the .so to /lib64 (with sudo privilege) or copy or mount to a folder which you add to LD_LIBRARY_PATH . Then the file command will show if it appears with correct characteristics.

I did all steps but when I

I did all steps but when I try to get libs the folder it is empty I get only the path without anything

Those run commands rely on

Gregg_S_Intel — Mon, 27 Jun 2016 16:15:57 GMT

Those run commands rely on the NFS mount and won't work without it.

Note that you can also use

Loc_N_Intel — Mon, 27 Jun 2016 17:03:24 GMT

Note that you can also use the utility micctrl to mount a directory (Section B.4.3.4 Adding an NFS mount in the MPSS User's Guide).
