Thanks Anton, I just wanted to show my appreciation for your work and for reporting your findings.
My opencl application is heavily dependent on double precision performance.
A lot of people out there have the attitude that you only need double precision for a few scientific problems.
The fact that every major computer language uses double precision for calculations and float is just a storage format eludes them. Ditto Excel using 16 digits of precision.
It would be great if someone could write a paper as to why double precision is so important for all uses.
Someone needs to invent a bitcoin that depends on double precision (or higher..) performance. (finding locations of a certain pattern in a mandlebot?)
Perhaps this would raise the desire for high DP performance in the general user base.
