Hi All,
I'm back with another question. I was attempting to compare and contrast
the advantages and/or disadvantages with the various backends available.
However, I seem to be encountering a runtime error with clBLAS which I was
hoping someone might be able to interpret and assist with. I'm running
PyFR v0.2.3. I've included the invocation and corresponding stack trace
for your review. Any input you might be able to provide as to the root
cause would be greatly appreciated.
pyfr-sim -n 100 -p -b opencl run couette_flow_2d.pyfrm couette_flow_2d.ini
