Thank you, David.I solved this problem.The command "mpirun" in Gmsh ran instead
of "mpich" I installed in PETSc.So I removed Gmsh and all mpi* and rebuilt
libMesh.I also fixed my mistake that did not set the path rightly when I
installed PTESc.Thank youagain for your help.Best regards,Kang----- Original

Re: [Libmesh-users] Using multi-core in execution filesThis has happened to me
before when I had two MPIs installed on my system (e.g. mpich and openmpi) so
that libMesh links to one during configuration and the other is used during
"mpirun".I suggest that you make sure there is only one MPI on your system and
then rebuild libMesh and try again.DavidOn Mon, Feb 12, 2018 at 9:19 PM, 강신성

Thanks for your reply, David.
I tried to the command "mpirun -np N" in the RB example 5, but there was a
problemthat the same code is running repeatedly as follows.

Other examples had the same problem, too.
Did I type the command wrong? If not, I want to know what is wrong.

Hello,
You can run the reduced basis code in parallel. You do it just the same
way that you run any other libMesh code in parallel, i.e. just run with "mpirun
-np N" where N specifies the number of processors that you want to use.
If you want more info on the parallelization approach that is used,
please refer to
this paper.
Best,
David

Hello everyone,
I am solving RB problems, but it takes too long because of many basis
vectors.
So, similar to "make -j 10", I want to know how to use multi-core in
execution files, not parallel programming.
Best regards,
S. Kang.
