Hi,
I could not find any information on this topic:

is it possible to use half-precision floating point in OpenACC? And if it is the case, how?


Thanks,

Enrico

No, sorry. You’re the first person to request it. Would it be something you want me to add as an RFE (request for enhancement)?

If it is possible: yes… it would be a very interesting feature for us.

Thanks and Best Regards,

I added TPR#23044 “OpenACC: support half-precision in device code” with your request.
