我正在考虑获得NUC8i7HVK。有一些必须的功能..NUC8i7HVK是否能够从Thunderbolt 3 JBOD启动Linux？Linux上的VEGA M问题是否已解决？我在运行密集的OpenCL或OpenGL应用程序时读到GPU会升温并降低功耗。我使用最新的4.18.3内核，amdgpu固件（包括vegam支持）修改了我的MacPro 2013 Black Can桌面上运行的Ubuntu 18.04（Bionic Beaver）最新的Mesa 18.3.0-devel，OpenGL 4.4。我计划出售我的MacPro。当Apple开始愚弄操作系统时，我从MacOS迁移了。当你比较NUC8i7HVK的性能规格对于MacPro 6,1 ..哈迪斯峡谷看起来并不太破旧。总的来说，我希望我的多核代码有点慢，但是GPU可以平衡一切，但我的Thunderbolt 3将不再需要Thunderbolt适配器并全速运行，VegaM图形将比AMD / Apple D700。我认为它会平衡，可能NUC8i7HVK会稍快一些。我一直在关注Debian / Ubuntu论坛。似乎完整的功能越来越近了。有没有人在论坛上试过这个呢？消息编辑：Al Hill - 删除了不适当的语言。以上来自于谷歌翻译以下为原文I am thinking about getting a NUC8i7HVK. There are a few capabilities that are a must.. Is a NUC8i7HVK capable of booting linux from a Thunderbolt 3 JBOD ?Is the VEGA M issues on Linux resolved ? I read when running intensive OpenCL or OpenGL apps the GPU will heat up and throttle down. I modified my Ubuntu 18.04 (Bionic Beaver) that runs off my MacPro 2013 Black Can desktop with the latest 4.18.3 kernel,amdgpu firmware (included vegam support)latest Mesa 18.3.0-devel, OpenGL 4.4.I plan on selling my MacPro.I migrated off MacOS when Apple started to dumb the Operating System down.When you comparethe performance specs of the NUC8i7HVK to the MacPro 6,1 .. the Hades Canyon does not look too shabby. Overall I expect my multi core code to be a little slower but theGPU may balance everything out, but my Thunderbolt 3 will no longer need the Thunderbolt adapter on it and run at full speed, The VegaM graphics will be faster than theAMD/Apple D700. I think it's will balance out and possibly the NUC8i7HVK will be slightly faster. I've been following the Debian/Ubuntu forums. It appears full functionality is getting close.Have any of you on the Forums tried this yet ? Message was edited by: Al Hill - inappropriate language removed.

你好，我刚刚收到了新的Windows 10秋季更新（RS5-1809），并且与每个新的Windows 10功能更新一样，Teaming功能也被破坏了。英特尔请告诉我们什么时候可以发布新的网络驱动程序？我的情况我使用的是双端口Intel x520 DA网卡。谢谢，基督教以上来自于谷歌翻译以下为原文Hello, I just received the new Windows 10 Fall Update (RS5 - 1809) and as with every new Windows 10 feature update the Teaming functionality is broken. Intel please tell us when we can expect a new network driver release? I my case I am using a dual port Intel x520 DA NIC. Thanks,Christian

on these NICs it causes all sorts of issues. We have CSVs go offline and report being corrupted and unreadable

大家早，当我在Citrix和GRID的这次旅程中进入第二年时，我们在无数配置上运行了90名Autodesk员工。我不得不说这款技术仍然是丰田普锐斯对Maclaren P1的看法。我们花了大约460,000美元来实施解决方案，即使它有点工作，如果我再次选择，我会购买90个工作站，每个2200美元。本可以节省25万美元，并且工作量会更小。让我们看看为什么，我会请其他读者聆听他们的意见。 - 即使有鼠标循环和各种其他注册攻击，AutoCAD工作区也很难通过Citrix进行配置。它仍然不准确，迟滞和痛苦。 - 网格不存在Citrix支持。您必须在网上搜索各种博客，Twitter以获取更多更新，以及第三方工具来调整系统以使其可远程操作。 -NVidia网格支持 - 嗯，这是我可以从供应商和社交媒体中的一大堆营销资料中找到的 - 我们使用K2，这是我去年买的最好的。 K220不够强大，K240不会做得很好，K260是可用的，而完整的GPU是用户想要的体面绘图。所以最多我可以把8个人放在35K美元的服务器上。这是每位用户$ 8K。 - 该软件非常多。现在我们的Win10图像将使用K240启动，但如果我改为更高的任何东西 - 我会连续重启。 - 不间断的补丁，我认为我们正在使用Xen服务器的补丁17，我们刚刚为GRID卡发布了一个积分版本，上面用K260杀死了一半的员工。 （K260可以在Windows 7上运行....） - 其他3D应用程序相当不错，SpaceGass，发明者，Navisworks和Revit似乎都比AutoCAD更好用。但他们都需要2GB视频卡，这是260个配置文件。 - 管理很简单，因为您只需更新一个工作站映像，每次更新后都需要更新每台计算机上的个人虚拟磁盘 - 在完成此操作后，允许每台计算机停机半小时。 - 网络流量和带宽很奇怪。我们运行局域网设置，一些虚拟机运行速度为60Mbit，每次运行约20分钟，其他运行速度为6左右.NFI为什么。 - 当你想要它时，电源管理和让VM打开和关闭有点受欢迎，DC有电源管理 - 但它不起作用，所以你必须使用shell。 - 别让我开始使用NVEnc和各种视频模式......实际上 - 我会在那里停下来，因为我开始听起来像个老生子。从我的经验来看，我们的系统正在运行，但最终用户和IT团队都希望我们没有实现它。虽然技术似乎很好，我们都可以制作一个看起来不错的演示，但运行工作站和服务器更简单，更便宜，同时使用DFS或PeerSync在站点之间组织数据。主要的问题是，当你实现这一点时，你是独立的，Citrix支持人员不知道什么是GRID卡，而你正处于bug之后的bug之后。我们从Citrix或GRID获得的每个新更新都可以解决一个问题，但接下来的几天您将解决新问题。我有一个由5个人组成的团队都拥有Citrix Qualifications，我们只是累了，疲惫不堪，最后一个GRID驱动程序更新打破了260个配置文件迫使我写这个。我们现在太深了，无法改变它 - 所以我们将继续尝试将其变为专业功能级别，也许M60卡更好，但我想再投入5万美元的视频卡只需一年老???祝你一切顺利，感谢你们迄今为止的阅读。以上来自于谷歌翻译以下为原文Morning all,As I enter my 2nd year on this journey with Citrix and GRID, we run 90 Autodesk employees on a myriad of configurations. I have to say that this tech is still what the Toyota Prius is to a Maclaren P1.We have spent around $460,000 implementing the solution and even though it sort of works, if i had my choice again, i would have just bought 90 workstations @ $2200 each. Would have saved myself $250K and would have a smaller workload.Lets go through why and I would ask fellow readers to chirp in with their opinions. - AutoCAD workspace is very hard to configure over Citrix, even with mouse cycles and various other reg hacks. It is still inaccurate, laggy and a pain. - Citrix support is non-existent for grid. You have to trawl the web for various blogs, twitter for more updates and 3rd party tools to tune the system to make it remotely workable. - NVidia Grid Support - well, this is all i can find from the supplier ans a tonne of marketing stuff in social media - We use K2, it was the best i could buy last year. K220 is not powerful enough, K240 wont do 3D very well, K260 is usable and a full GPU is what the user wants for a decent drawing. So at best i can put 8 people on a $35K server. That is $8K per user. - The software is very buggy. Right now our Win10 image will boot with a K240, but if i change to anything higher - i get continuous reboots. - The incessant patching, i think we are on Patch 17 for Xen server and we just had a point release for the GRID cards, which as above killed half my workforce with the K260. (K260 works on Windows 7 though....) - The other 3D apps are quite good, SpaceGass, inventor, Navisworks and Revit all seem to be much better to use than AutoCAD. But they all need 2GB vid cards which is the 260 profile. - management is easy as you only have the one workstation image to update, you do need to update the personal vDisk on each machine after each update - allow half and hour of downtime for each machine whilst this is done. - Network traffic and bandwidth is just weird. We run a LAN setup and some VM run at 60Mbit for about 20 minutes at a time and others sit at around 6. NFI why. - Power management and getting VM's to switch on and off when you want them to is a bit of hit and miss, the DC have power management - but it doesn't work, so you have to use the shell. - Dont get me started on NVEnc and the various video modes...Actually - i will stop there as i am starting to sound like whingey old man. The takeaways from my experience is that, we have the system working, but both the end users and the IT team wish we hadn't implemented it. Whilst the tech seems good and we can all make a demo that looks good, it is simpler and cheaper just to run workstations and servers, whilst using DFS or PeerSync to organise the data between sites.The main problem is that you are on your own when you implement this, Citrix support has no idea what GRID cards are and you are on the bleeding edge working around bug after bug after bug. Every new update we get from Citrix or GRID may fix one issue, but the next few days you are working around new ones. I have a team of 5 guys all with Citrix Qualifications and we are just tired, worn out and the last GRID driver update that broke the 260 profile has forced me to write this.We are in too deep to change it back now - so we will continue to try and get this to a professional functional level, maybe the M60 cards are better, but do i want to throw another $50k at video cards that are only a year old ???i wish you all the very best, thanks for reading this so far.
