<div dir="ltr">Hi,<div><br></div><div>My apologies if this question has been previously discussed. I just joined the list and all I know is that from reading the docs and release comments, writing code for double precision on GPU's is not a priority.</div><div><br></div><div>However, I believe all recent upper-end Nvidia cards have native double precision (which was not true several generations ago). So, you don't have to have a real "scientific computing" GPU to take advantage of this -- most people probably already have the hardware. Still, I understand that most people do not need/want to run double precision. But, some do (and you have to if you are concerned with conservation of energy -- the energy drift in single precision is substantial).</div><div><br></div><div>So, I would like to ask what the level of effort to do this is believed to be? Would it require a lot of new code, or would it be porting the single precision code to double precision?</div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr">Sincerely,<br>
