It's almost a tautology -- I know several recent supercomputers that have GPUs not because of mission drive, but to 'inflate' the LINPACK results to satisfy the sponsor's demands for performance numbers. It's hoped the users will adopt the GPUs, but that doesn't always happen; see the discontinued Xeon PHI accelerators for an example of that. When that happens, you've got a lot of idle GPUs...
