Hi,
I've encountered some problems with trying to use openmp with windows. I've
followed
https://groups.google.com/forum/#!searchin/pyfrmailinglist/windows$2010%7Csort:date/pyfrmailinglist/Kaygd-9ni2k/42IqyZfIBAAJ
for
the setup for the most part.
While trying to run
mpiexec -n 2 pyfr run -b openmp -p euler_vortex_2d.pyfrm euler_vortex_2d.ini
I got the error message
File
"C:\Users\admin\AppData\Local\Programs\Python\Python36\lib\ctypes\__init__.py",
line 348, in __init__
self._handle = _dlopen(self._name, mode)
OSError: [WinError 126] The specified module could not be found
job aborted:
[ranks] message
[0] application aborted
aborting MPI_COMM_WORLD (comm=0x44000000), error 1, comm rank 0
[1] terminated
---- error analysis -----
[0] on BEAST
pyfr aborted the job. abort code 1
---- error analysis -----
I am having really big trouble seeing what this error message means. I
thought it was missing some dll, but cant figure out at all what dll that
would be. I've tried reinstalling pyfr from pip and the setup.py, but it
makes no difference.
Anyone has any idea what is wrong?
(Running on windows 10, microsoft MPI, two xeon cpus, pyfr 1.7.5)
