Since we are always keen to optimize and speed-up our algorithms I'm wondering if oneAPI offers something for us.</P><P>Has anyone experience/is it possible at all to use the GPU for 80 Bit floating point calculations? Or are there are libraries that can use a GPU to simulate 128 Bit floating point calculations?</P><P>To us it looks x87 stuff is still available (and hopefully will be in the future) but is not an active development focus, so no innovations to expect.</P> Fri, 21 Feb 2020 12:52:48 GMT Robert_M__Münch 2020-02-21T12:52:48Z https://community.intel.com/t5/Software-Tuning-Performance/Floating-Point-80-Bit-oneAPI-GPU/m-p/1128927#M6369 <P>Hi, our application uses 80 bit FP code because we need the additional precision.
