#SIMD instructions for #AMD’s znver6 processor: “AVX512BMM instructions include Bit Matrix Multiply and Bit Reversal operations.” “2 parallel 16x16 non-transposed fused BMM-accumulate (BMAC) with OR/XOR reduction. Each 256-bit chunk of a zmm register holds a 16x16 bit matrix. The third source matrices for accumulation are in zmm1.” This is a binutils patch from Umesh Kalvakuntla at AMD.
on 02025-11-11Jpotter145 reports that in Missouri, USA, NVIDIA #hardware #pricing is US$1900 for a 3080 and #AMD is US$440 for a 6600, US$800 for a 6700, and US$2400 for a 6900XT.
on 02021-11-02#GPGPU #mining is said to be driving up #AMD #hardware #pricing
on 02021-11-02apparently #RADV is faster not only than #AMDVLK but also AMDVLK is usually faster than #AMD’s proprietary “PRO” driver?
on 02021-11-02apparently #AMD Vega 64 GPU #hardware went for US$350 last year but #pricing has risen to more like US$500–800 since then due to altcoin #mining; this person upgraded from their Vega 56 to a Radeon 6900XT at 1.8× the MSRP
on 02021-11-02"AMDVLK" is the open-source #AMD #Vulkan 1.2 implementation provided by AMD, perhaps outdated by #RADV

on 02021-11-02the #ROCm #AMD #OpenCL #GPGPU repo
on 02021-11-02"ROCm" is Radeon Open Compute, which provides reasonable #OpenCL support for #AMD #GPGPU computing on Linux (OpenCL 2.0) and is MIT-licensed
on 02021-11-02Apparently #OpenCL on #Vulkan sucks; neither #clspv nor #clvk is soup yet, and OpenCL support in #Mesa is still “dismal” (because only 1.2 I guess), but gets better with #AMD’s #ROCm and really good with NVIDIA’s proprietary driver. #GPGPU
