[mpich-discuss] Can't get MPICH2 to work on a MAC - Need Help

[Ron Pape]

Hi.

 

We have an 8 core MAC Pro 4.1 with an OS X Version 10.57 operating system
with the following specifications: 


  

  Processor Name:        Quad-Core Intel Xeon

  Processor Speed:        2.26 GHz

  Number Of Processors:           2

  Total Number Of Cores:          8

  L2 Cache (per core):   256 KB

  L3 Cache (per processor):       8 MB

  Memory:         16 GB 1066 MHz DDR3

  Processor Interconnect Speed: 5.86 GT/s

 

We are using the FDS (Fire Dynamics Simulator) computational fluid dynamics
code developed by NIST, and we need to run in the parallel processing mode
using MPICH2.  We have successfully done this using a less powerful Windows
PC, and we can run multiple grids in the serial mode using the MAC Pro.
However, when we try to run in the parallel mode on the MAC, we get the
following error message:

 

Command:

fds1:FDS rpape$ mpiexec -n 4 ./fds5_mpi_osx_64 cone.fds

 

Error Message:

dyld: Library not loaded: /usr/local/lib/libmpi_f77.0.dylib

  Referenced from: /Users/rpape/FDS/./fds5_mpi_osx_64

  Reason: no suitable image found.  Did find:

            /usr/local/lib/libmpi_f77.0.dylib: mach-o, but wrong
architecture

            /usr/local/lib/libmpi_f77.0.dylib: mach-o, but wrong
architecture

 

Here we tried a Windows version of libmpi_f77.0.dylib, because we could not
find one in the MAC architecture.  Can we obtain a version of this in the
MAC architecture? 

 

We have tried to configure as in the following, without success:

 

configure --enable-f90 --enable-f77 --enable-sharedlibs=osx-gcc
--with-pm=mpd --enable-fast --prefix=/usr/local CC=/opt/local/bin/gcc-mp-4.5
FC=/opt/local/bin/gfortran-mp-4.5 \ | tee configure.log

 

We would appreciate any help you can provide.  

 

Thank you very much,
