Hi All
I had installed the cp2k-7.1 and cp2k-8.2(GPU version). Then I wanted to
test their calculation speed. The result is cp2k-8.2 > cp2k-7.1 >
cp2k-8.2(with GPU).I was confused that the GPU could not accelerate
calculation.
Could anybody give me some advice?
The input and output files are attached.
