Quoting https://en.wikipedia.org/wiki/Half-precision_floating-point_format : Support for half precision in the x86 instruction set is specified in the F= 16C instruction set extension, first introduced in 2009 by AMD and fairly broad= ly adopted by AMD and Intel CPUs by 2012. This was further extended up the AVX-512_FP16 instruction set extension implemented in the Intel Sapphire Ra= pids processor. Quoting https://en.wikipedia.org/wiki/F16C : The F16C[1] (previously/informally known as CVT16) instruction set is an x86 instruction set architecture extension which provides support for converting between half-precision and standard IEEE single-precision floating-point formats. Is your hardware missing the F16C instruction set extension? --=20 You are receiving this mail because: You are the assignee for the bug.=
