WebAug 28, 2016 · There is support for textures using half-floats, and to my knowledge this is not limited to the driver API. There are intrinsics __float2half_rn () and __half2float () for converting from and to 16-bit floating-point on the device; I believe texture access auto-converts to float on reads. WebOct 12, 2024 · The pytorch devs could not compile binaries for the new RTX GPUs because of a bug in the Cuda Toolkit. A fix for that is likely to be part of pytorch 1.7.1 (or so they hope), but in the meantime they did add a fix to the 1.8 nightlies. You should install those builds if you can. WebJul 15, 2015 · As noted in the CUDA C Programming Guide, the bit layout of ‘half’ operands on the GPU is identical to the 16-bit floating-point format specified by IEEE-754:2008.
