I've just reviewed a manuscript about the recent progresses made to introduce #GPU support in a classic, large #CFD code with existing good support for massive simulations on traditional #HPC settings (CPU clusters).
I'm always fascinated by the stark difference between the kind of work that goes into this process, and what went into the *reverse* process that we followed for #GPUSPH, which was developed for GPU from the start, and was only ported to CPU recently, through the approach described in this paper I'm sure I've already mentioned here:

When I get to review this kind of articles, I always feel the urge to start a dialogue with the authors about these differences, but that's not really my role as the reviewer, so I have to hold back and limit my comments to what's required for my role.
So I guess you get to read about the stuff I couldn't write in my reviewer comments.
