Hi,
I am a newbie to Linux and to PyFr. I have to work on a virtual machine for
the moment. And for the time being I try to use PyFR with OpenMp but no
chance so far. This is the error I get:
/Documents/examples/couette_flow_2d$ sudo pyfr run -b openmp -p
couette_flow_2d.pyfrm couette_flow_2d.ini
Traceback (most recent call last):
File "/usr/lib/python3.4/configparser.py", line 762, in get
value = d[option]

return self.__missing__(key) # support subclasses that
define __missing__
File "/usr/lib/python3.4/collections/__init__.py", line 806, in
__missing__
raise KeyError(key)
KeyError: 'cblas'
During handling of the above exception, another exception occurred:

Could you tell me what is wrong please? I installed OpenBlas and changed
the numpy site config file accordingly.
Additionally, I have been trying to find the best way to use PyFR for the
last couple of days.
At school, I have access to a PC with a quadro 600 GPU (just single
precision, CUDA 2.0) but I cannot install Linux. So I have to use the
virtual machine with which I cannot use the GPU. At home I do not have a
compute GPU. So I have to use OpenMp on a Windows machine. I installed
Anaconda and Visual Studio Python tools. I would appreciate any
suggestions about how I can install OpenMP to Win64. If I can succesfully
run the examples on my home PC, I will try the same approach at the school
on multi-cpu.
Thanks,
I wish you all a nice day,
Cheers,
Emre
