What MPICH version are you using? You may be using a too old one which does not incorporate that functionality. You can download the latest one (3.1.1) from www.mpich.org. Antonio On 06/12/2014 09:25 AM, Klaus Philip wrote:

Hi,

This is my first post to this mailing list.

After working two month with mpich2 I decided to try the Intel MPI Benchmark.

The strange thing is, that at compiling the sources, I get an linker error when mpicc wants to compile the files for the asynchronous communication.

Further I can use the asynchronous function in my self-written programs without any problems or errors.

*_So this is the command I execute:_*

/home/rpimpi/mpich2-install/bin/mpicc -O0 -DNBC IMB.c IMB_declare.c IMB_init.c IMB_mem_manager.c IMB_parse_name_nbc.c IMB_benchlist.c IMB_strgs.c IMB_err_handler.c IMB_g_info.c IMB_warm_up.c IMB_output.c IMB_allreduce.c IMB_reduce_scatter.c IMB_reduce.c IMB_bcast.c IMB_barrier.c IMB_allgather.c IMB_allgatherv.c IMB_gather.c IMB_gatherv.c IMB_scatter.c IMB_scatterv.c IMB_alltoall.c IMB_alltoallv.c IMB_sendrecv.c IMB_init_transfer.c IMB_chk_diff.c IMB_cpu_exploit.c -o IMB-NBC

*_And this is the output I get:_*

I hope someone of you can help me concerning this problem.
