Dear colleagues,<br>
<br>
I'm trying to get the parallel version of WIEN2k 14.2 running on the institute's cluster, but I'm stuck now.<br>
I searched the mailing list for the error message I receive, but at first glance I did not find relevant postings.<br>
<br>
This is the problem I face:<br>
The serial version of WIEN2k is running fine (also when using qsub and the submission system).<br>
However, when trying to use the parallel version I get the following error when lapw1 is invoked in parallel mode:<br>
"Intel MKL FATAL ERROR: Cannot load symbol MKLMPI_Get_wrappers."<br>
<br>
Here the facts on hard- and software:<br>
I'm using WIEN2k 14.2 to run the example TiC case from the UG as a test to see whether all works out fine.<br>
I compiled the sofware using the Intel Cluster Studio with the Intel Fortran Compiler 16.0, Intel C++ Compiler 16.0, Intel MKL 11.3 and Intel MPI.<br>
I compiled it using FFTW3 and the MKL lapack, scalapack and blacs.<br>
<br>
The cluster consists of 37 nodes with 20 CPUs each. It is running a CentOS Linux distribution and it is using SGE as submission system. In the submission script orte is used as the parallel environment.<br>
<br>
This is what I've tried so far:<br>
I don't know why it can't find things from the MKL as I export all my environmental variables using the submission script, which I also checked by printing them.<br>
As additional information I include the submission script (WIEN2k-test-p.sh, which is still a bit messy as I adopted it from another program for testing reasons), the :parallel file with the error messages (which I renamed to .parallel so that Thunderbird on
Windows can handle it), the output-file (TiC.o14540) and the .machines file.<br>
<br>
I get the same error messages when using OpenMPI instead of the IntelMPI, but the output is a bit different (see TiC.o14541).<br>
<br>
I did try different ways to export my environmental variables (to get rid of unnecessary stuff), also tried mpi as the parallel environment in the submission script instead of orte. I also tried to request a different number of slots,...<br>
But nothing off this got me rid of this error message.<br>
<br>
Has anybody experienced a similar problem or are there any hints what else I can check?<br>
<br>
Thanks for your help.<br>
All the best,<br>
