You have the wrong blacs for openmpi, please use the Intel link advisor I sent to work out what you need. It looks like you may need static linking with openmpi.
I am certain that you misread the email about "-C -g", it will only diagnose problems and will in general create problems (and make the programs run 25-50% slower).

Dear professor:
I use Open MPI, version 1.4.5.
I added "-C -g" because some people in the mail-list said it probably will solve the problem. Thanks for your advice, I will recompile the package soon.

Dear Professor:
When I type "mpif90 --version", it give me " ifort (IFORT) 12.1.3 20120212". So, I thought it should work.
My Libraries linking are listed below:Parallel excution: FFTW_LIB + FFTW_OPT : -lfftw3_mpi -lfftw3 -L/opt/fftw3.3.3/lib + -DFFTW3 -I/opt/fftw3.3.3/include (already set) RP RP_LIB(SCALAPACK+PBLAS): -lmkl_scalapack_lp64 -lmkl_blacs_lp64 $(R_LIBS) FP FPOPT(par.comp.options): -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML -traceback -assume buffered_io Compiler Option

Subject: Re: [Wien] Segmentation fault in Supercell Calculation Your options are probably wrong:
a) mpif90 is normally gfortran, the Intel version is mpiifortb) It is easy to use the wrong linking with the Intel mkl libraries. Please provide the information I requested.

Dear Professor:
Yes, "x lapw0" works without mpi.
My mpi compile : mpif90I use Open MPI， version 1.4.5the parallel compilation options are
-FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML -traceback -assume buffered_io
I use Intel MKL libraries, that part should be fine.
Thanks very much for your help.

Subject: Re: [Wien] Segmentation fault in Supercell Calculation Does a simple "x lapw0" work, i.e. without mpi, for this specific case?
If it does then there is probably an error in how you have linked/compiled the mpi versions. Please provide:
a) The mpi compiler you used.b) Which type of mpi you are using (openmpi, mvapich, intel mpi etc)c) The parallel compilation options.
N.B., a useful resource is https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor
N.N.B., ulimit -s is not needed, this is (now) done in the software.

Dear Professor Marks:
I've check everything you have mentioned, they are all fine, nevertheless it still don't work. I think the input files are ok since I have no problem running in non-parallel mode. I tried to make the supercell smaller (2x1x1), then it works. However, I don't know why that happens. By the way, I have "ulimit -s unlimited " in my .bashrc file. I'v also adjusted the RKMAX and RMT before.

Subject: Re: [Wien] Segmentation fault in Supercell Calculation You have what is called a "Segmentation Violation" which was detected by 4 of the nodes and they called an error handler which stopped the mpi job on all the CPU's.
This is normally because you have an error of some sort in your input files, any of case.in0, case.clmsum (and clmup/dn if you are using spin polarized).
1) Check that you do not have overlapping spheres and/or other mistakes.2) Check your error files, e.g. "cat *.error". Are any others (e.g. dstart.error) not empty? Did you ignore an error during setup?3) Check the lapw0 output in case.output0* -- maybe shows what is wrong.
There are many possible sources, you have to find the specific one.

Dear WIEN2k user:
I am using wien2k_14.2 on CentOS release 5.8. ifort version 12.1.3 with MKL.
After generating a 2x2x1 supercell with 30 atoms, I tried to do the scf calculation. However, I got some errors. I'v attached it at the end of this email. My wien2k was installed correctly. It works well for other calculations. It also worked if I run non-parallel calculation for supercell. I'v searched the mail-list, but can't find any solutions. Could you give me a hint on how to solve the problem? Thank you very much.
