[CP2K-user] [CP2K:16357] Is the GPU version cp2k slower?

[Yanyan Zhang]

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.
