Unable to compile the code for Xeonphi

I wrote a MPI Program for running on Xeon phi in native mode.
When I tried to compile the code, the following errors are coming.

$mpicc test.c -o test -mmic

/usr/bin/ld: skipping incompatible /opt/intel//impi/ when searching for -lmpifort
/usr/bin/ld: skipping incompatible /opt/intel//impi/ when searching for -lmpifort
/usr/bin/ld: cannot find -lmpifort
collect2: ld returned 1 exit status

Please help me out.

OFFLOAD_REPORT: Why is CPU Time smaller than MIC Time?


from compiler-assisted offload code, I get the following offload report:

[Offload] [HOST]  [Tag 2] [CPU Time]        5.053540(seconds)
[Offload] [MIC 0] [Tag 2] [CPU->MIC Data]   1080 (bytes)
[Offload] [MIC 0] [Tag 2] [MIC Time]        6.122002(seconds)
[Offload] [MIC 0] [Tag 2] [MIC->CPU Data]   1032 (bytes)

However, I expected that the total CPU time on the host is always greater than the MIC time on the mic, since it includes the execution time on the mic according to:

Aligned Allocators with C++11 on the MIC?

Short version: is this possible?

Long version: I have tried to use aligned allocators either directly or indirectly for a couple of different projects using the Xeon Phi, and have yet to be successful in compiling it x0 My understanding is that the allocator rules / parameters / syntax changed (again) similar to this issue:

    It’s that time of year again, when the pundits look into the future and offer predictions for what’s in store for the New Year and beyond. Frank Gens, chief analyst at IDC, has been looking in his crystal ball to foretell the top technology predictions for the next three to five years.

    Spoiler alert: If you’re a business executive or line-of-business (LOB) decision-maker, what he foresees might have a big impact on your job. Whether it is a positive or negative impact is, as always, up to you to determine.

    Which BLAS 2 operations in MKL are threaded on the Phi?


    I guess the subject line tells it all. I am specifically interested in the dgemv routine.The only reference I could find about this is the following web page:

    where it is mentioned that the ?gemv routines are threaded with OpenMP* for Intel® Core™2 Duo and Intel® Core™ i7 processors. So, there is no threaded implementation of BLAS 2 for the Phi?
