Packages required for the MPI

[bitelaum]

Hi,rnrnI’m not a great expert in paralellism, so I’m having some problems using the MPI option in OpenLB makefile.rnrnWhen I run a “”make all”” to build the libs, I get some errors like:rnrn

Code:

icpc -D__aligned__=ignored -DPARALLEL_MODE_MPI -DOLB_PRECOMPILED -O3 -Wall -I../../src -I../../src/external -I../../src/external/cvmlcpp -I../../src/external/boost -I../../src/external/kaffpa -c serializerIO.cpp -o ../../build/precompiled/obj/serializerIO.orn../../src/complexGrids/mpiManager/mpiManager.h(29): catastrophic error: cannot open source file “”mpi.h””rn #include “”mpi.h””rn ^rnrncompilation aborted for serializerIO.cpp (code 4)rnmake[1]: *** [../../build/precompiled/obj/serializerIO.o] Error 4rnmake[1]: Leaving directory `/home/bitz/Documents/IC/Pacotes/olb-0.7r1/src/io’rn– Leaving src/io (compile)rn

rnrnWich packages should I install in my system to get the MPI to work (if it’s really the lack of some package)?rnrnI’m running Ubuntu 12.04 64bits, so repositories packages are welcomed.rnrnThanks,rnHenrique.

Hi,rnrnI solved my problem using this tutorial:rnrnhttp://software.intel.com/en-us/articles/performance-tools-for-software-developers-building-open-mpi-with-the-intel-compilers/rnrnI just compiled the OpenMPI (in my case with the intel compilers) and after all used the MPI option in OpenLB makefile, changed the CXX to the MPI wrapper mpiCC).rnrnSorry about this thread.rnrnThanks,rnHenrique.
