?K2-240Q档案P40-P40-8Q除了卡之外,服务器是相同的。在HP GEN9主机中运行 - 我还考虑在我们的服务器中运行一些具有1:1 GPU的工程师并禁用FRL。我在K2上做到这一点时看到了巨大

HDMI 1.4x/2.0x 规范中定义的传统 TMDS 信号,也支持 HDMI 2.1x 规范中开发的 FRL 信号。它检测从源传输的信号类型,并自动切换到适当的通信模式。此外,完全支持启用

你好。驱动程序352.83 / 354.80(在网格K2上)可能存在错误/功能。帧速率限制器(默认情况下启用frame_rate_limiter 1 / frl_config 0x3C)限制为70

你好。完整配置文件k180 / k280占用所有GPU K1 / K2,但在Dom0中保留320MB vram和vgpu / libnvidia-vgpu进程除外。该配置文件不共享vGPU计算能力,不需要Dom0调度程序。为什么默认情况下为该配置文件启用了“frame_rate_limiter”?禁用是否会从GPU中删除虚拟化开销(Dom0调度程序)?为什么默认情况下该配置文件禁用“cuda_enabled”?我想Dom0调度程序不能处理CUDA进程的共享(时间分片),但只有DomU并发应该是可能的。我知道这个参数是有意保护的新驱动程序中的数字签名(> 6/2015 in vgpuConfig.xml)因此我使用的是较旧的驱动程序。谢谢你的技术答案,M.C>以上来自于谷歌翻译以下为原文Hello.The full profiles k180/k280 occupy all GPU K1/K2 except reserved 320MB vram and vgpu/libnvidia-vgpu process in Dom0. The profile does not share vGPU computing power and Dom0 scheduler is not needed.Why is there enabled "frame_rate_limiter" by default for that profiles ?Does the disabling remove virtualization overhead (Dom0 scheduler) from GPU ? Why is there disabled "cuda_enabled" by default for that profiles ?I suppose that Dom0 scheduler does not able to handle sharing (time slicing) for CUDA processes but there is only DomU concurrency that should be possible.I know that this parameter is intentionally protected by digital sign in new drivers (>6/2015 in vgpuConfig.xml) therefore I am using older driver.Thanks for technical answer, M.C>

传感器贴片的概念。现在,凭借可支持智能传感器贴片开发的RF430FRL152H近场通信(NFC)传感器应答器,我们离这个梦想又近了一步。 有了智能传感器贴片,人们可自行控制体温、脉搏率、水合作用或血糖等重

大家好,我们在带有Tesla P4的dell R740服务器中使用linux。我们正在使用GPU对ffmpeg进行一些测试,没有使用GPU,我们得到了相当多的FPS,我们觉得很奇怪。没有GPUffmpeg -i Samsung_UHD_Soccer_Barcelona_Atletico_Madrid.ts -threads 0 -map 0:0 -b 500k -c:v libx264 -s 320x240 -y test.h264frame = 1068 fps = 77 q = -1.0 Lsize = 1282kB time = 00:00:21.32 bitrate = 492.5kbits / s speed = 1.53x用GPU ffmpeg -hwaccel cuvid -c:v hevc_cuvid -i Samsung_UHD_Soccer_Barcelona_Atletico_Madrid.ts -map 0:0 -b:v 500k -c:v h264_nvenc -pixel_format yuv420p -r 25 -vf scale_npp = 320:240 -y test1.h264frame = 415 fps = 66 q = 39.0 Lsize = 1044kB time = 00:00:16.60 bitrate = 515.4kbits / s dup = 0 drop = 411 speed = 2.62x另一个奇怪的事情是,即使我同时运行不同的进程,GPU的使用总是相同的....大约9%utilization.gpu [%]9%utilization.gpu [%]10%utilization.gpu [%]9%utilization.gpu [%]10%utilization.gpu [%]有没有人有ffmpeg来解释这个?最好的问候和提前感谢以上来自于谷歌翻译以下为原文Hi all,We are using linux in a dell R740 server with a Tesla P4. We are doing some test with ffmpeg using the GPU and without, we get quite much FPS without using the GPU, what we find weird.
