Hello sir,

When I tried to compile SU2 v4.0.0 with MPI, I met the same problems with @nilesh (http://www.cfd-online.com/Forums/su2...-same-job.html), the parallel nodes were just doing the same job, I tried to solve the problems referring to the Installation Guide (http://adl-public.stanford.edu/docs/...D/Installation), the problems persisted.

Now I tried to compile SU2 v4.0.1 with MPI and CGNS support, I installed CGNS lib already and used newer way to specify mpi(using "--enable-mpi --with-cc=/path/to/mpicc --with-cxx=/path/to/mpicxx"), and my full configuration is as follows

"./configure --prefix=/home/ma/Applications/SU2/su2_v4.0.1 --enable-mpi --with-cxx=/usr/bin/mpicxx --with-cc=/usr/bin/mpicc CXXFLAGS="-O3" --with-CGNS-lib=/home/ma/Applications/CGNSLIB-3.2.1/lib --with-CGNS-include=/home/ma/Applications/CGNSLIB-3.2.1/include --with-HDF5-lib=/home/ma/Applications/HDF5-1.8.15/lib --with-HDF5-include=/home/ma/Applications/HDF5-1.8.15/include LIBS="/home/ma/Applications/HDF5-1.8.15/lib/libhdf5.a -ldl" 2>&1 | tee c.txt"

And after I installed SU2 correctly , I used "mpirun -n 2 SU2_CFD turb_SA_NASA0714.cfg", the problems persisted. I don't know what to do now. Please help me.

I am using an i5 machine with 2 cores (multithreaded to 4) with the latest version of SU2 on Ubuntu 14.04 LTS.

Thanks.






HERE, I used “mpirun -n 2 SU2_CFD turb_SA_NASA0714.cfg" command and the execution result showed that both threads were only running on one core!

Here is the configure result (http://pan.baidu.com/s/1mgCet9Q)
Here is the make result (http://pan.baidu.com/s/1hqGqouS)
Here is the make install result (http://pan.baidu.com/s/1qW1gLiO)

Problems solved.

I installed both mpich and openmpi, and I used openmpi to configure SU2, when I use mpirun command, the system automatically calls mpirun.mpich, to execute parallel su2 correctly, just use "mpirun.openmpi -n 4 SU2_CFD *.cfg".

Hope this will help you.

Thanks.
