在Tesla M6上使用三个屏幕所需的最小vGPU配置文件

嗨,
对于我的客户,我们正在认真考虑使用nVidia Grid技术。
我们的用户(大约600个并发(!))可以被视为知识工作者。
他们使用2D GIS应用程序,有时使用流式视频CCTV,其他应用程序不是图形密集型。
这就是为什么我们想使用只有512 MB内存的配置文件,这样我们就可以为每个M6卡支持16个并发用户。
这个客户端的不寻常的事情是使用多个屏幕。
所使用的瘦客户机(基于当前计划)将配备3个屏幕,一个34英寸,分辨率为3440x1440,两个分辨率为2560x1440(因此略低于UHD的最大支持分辨率)。
基于此页面上的信息:http://www.nvidia.co.uk/object/buy-nvidia-grid-uk.html,似乎有一个限制,暗示使用两个以上的屏幕
,你需要使用2GB或更多内存的配置文件。
这意味着我们每个M6卡只能支持4个并发知识工作者。
这使得使用NVidia Grid的商业案例变得不那么有趣了。
如果有可能将512 MB(或1024 MB)配置文件与上述三个屏幕结合使用,请告诉我?
两个和四个屏幕的限制是硬技术限制,还是取决于使用的分辨率?
考虑到这个项目的规模,我非常感谢一个认真的答案。
非常感谢你提前!
亲切的问候,

Hi,

For my client we are seriously considering the use of nVidia Grid technology. Our users (about 600 concurrent(!)) can be considered knowledge workers. They use a 2D GIS applicaton and sometimes streaming video  CCTV, the rest of their apps is not graphically intensive. That is why we would like to use the profile with just 512 MB of memory, so that we can support 16 concurrent users per M6 card. The unusual thing about this client is the use of multiple screens. The thin clients used will (based on the current plans) be equipped with 3 screens, one 34 inch with a resolution of 3440x1440 and two with a resolution of 2560x1440 (so somewhat lower than the maximum supported resolution of UHD). Based on the information on this page: http://www.nvidia.co.uk/object/buy-nvidia-grid-uk.html, there seems to be a limit, with implies that with the use of more than two screen, you need to use the profile with 2GB of memory or more. This would imply that we can only support 4 concurrent knowledge workers per M6 card. This makes the business case for the use of NVidia Grid much less interesting. Could you please let me know if there is a possibility to use the 512 MB (or 1024 MB) profile in combination with the three mentioned screens? Are the limits of two and four screens hard technical limits, or also dependent on the resolution used?

I would very much appreciate a serious answer, given the size of this project. Thank you very much in advance!

With kind regards,

Roel van Vuuren

这是正确的,无论其分辨率如何,都是固定数量的显示器。
在此处的文档中可以找到更多信息

对于您所描述的解决方案,您需要为Virtual Workstation Extended许可的2GB vGPU配置文件,因为您需要3个显示器,其中一个超过256x1600。

This is correct and is a fixed number of displays regardless of their resolution.

Some further information can be found in the documentation here

For the solution you're describing you'll require a 2GB vGPU Profile licensed for Virtual Workstation Extended as you require 3 displays, one of which exceeds 256x1600.

亲爱的杰森,
谢谢你的答案很清楚,不幸的是我们担心的答案,但仍然是可以理解的。
由于这似乎只是一个软件限制,我想知道自定义配置文件的正式请求是否有机会。
基于这样的事实,没有合适的配置文件(只有一个对我们的用例具有性能过度杀伤),并不是唯一的,并且具有相当大的潜在用户组,我希望您可以考虑这一点。
如果不是这张卡那么可能是下一个版本。
我的用例是急诊室人员(警察,消防和救护车911调度),需要同时使用多个应用程序(GIS,调度系统,办公室,闭路电视等)。
他们需要一个具有多个屏幕(超过2个,当前为6 19英寸,可以追溯到3个大屏幕)的系统,具有一些图形性能,但与3D设计师无法比较。
虚拟桌面的要求也不高,大约2个VC和8 GB的内存。
这就是为什么使用具有2 GB内存的网卡对于整合率(每个服务器的VM)来说也是非常具有破坏性的。
对于像荷兰这样的小国家的客户,我们需要至少600个并发虚拟桌面。
我不认为出售40块M6卡会导致NVidia的库存增加,但这个特定的用例及其对国家安全的重要性可能会引起人们的兴趣。
如果我们提交一份适合我们(可能还有其他人)需求的自定义配置文件的正式请求,请您告诉我是否有机会取得成功。
如果您认为Nvidia Grid不适合此用例,请告知我们。
再一次非常感谢你!

Dear Jason,

Thank you for the clear answer, unfortunately exactly the answer we were fearing, but very understandable nonetheless. Since this seems to be a software limitation  only, I wonder if a formal request for a custom profile might have a chance. Based on the fact there is no suitable profile (only one with performance overkill for our usecase), isn't unique, and has quite a large potential usergroup, I hope you  can take this into consideration. If not with this card then perhaps with a next release.

My usecase is emergency room personnel (911 dispatch for Police, Firedepartment and Ambulance), which require the concurrent use of multiple applications (GIS, dispatch system, Office, CCTV, etc.). They require a system with multiple screens (more than 2, currenty 6 19 inch, going back to 3 big screens) with some graphical performance, but not comparable with 3D designers. The requirements for the virtual desktops are not that high either, about 2 VCores and 8 GB of memory will do. That is why the use of Grid cards with 2 GB of memory would be quite devastating for the consolidation ratio (VM's per server) as well. For my client in a small country like the Netherlands alone we require at least 600 concurrent virtual desktops. I don't imagine the sale of 40 M6 cards will lead to a stock rise for NVidia, but this specific use case and its importance for national security might be of interest.

Could you please let me know if, given this usecase, there is a chance of success if we submit a formal request for a custom profile which will fit our (and probably others) needs. If you think that Nvidia Grid isn't designed or suited for this usecase, also please let me know.

Thank you very much again!
