嗨,我也对此有服务请求,但我认为查询社区会很好,因为这是一个特殊的设置,许多不幸的选择已经强制要求。我们正在尝试在Google云端实例上运行浮动许可管理器,并在本地计算机上使用浮动许可证,但它无法运行。我们在Centos-6谷歌云实例上运行Vivado 2017.4。谷歌云计算机很烦人,他们有一个内部主机名(server_internal_hostname)和外部主机名(server_external_hostname)从外部,您可以使用external_server_hostname访问计算机(ssh等),但在内部,计算机将自身视为internal_server_hostname。我们单独安装了FlexLM 11.14我们设置浮动许可证文件(许可证文件使用internal_server_hostname(即SERVER internal_server_hostname)我们创建了一个自动启动lmgrd的flexlm服务,它也启动了xilinxd(以及cdslmd用于节奏)lmgrd配置为使用端口5280(已打开)在服务器上,我配置了XILINDX_LICENSE_FILE = 5280 @ external_server_hostname运行Vivado 2017.4可以运行并查看许可证。在工作中,我们有一台本地机器,我们称之为client_machine。它正在运行centos7(我们别无选择)在client_machine上,我们安装了Vivado 2018.1(因为2017.4将无法在Centos 6上运行)在client_machine上,我configureXILINDX_LICENSE_FILE = 5280 @ external_server_hostname当我在客户端计算机上运行Vivado 2018.1时,它无法查看许可证。使用lmutil:lmutil lmdiaglmutil- 版权所有(c)1989-2016 Flexera Software LLC。保留所有权利.FlexNet诊断于Sun 6/17/2018 19:13-------------------------------------------------- ---许可证文件:5280 @ external_server_hostname ----------------------------------------- ------------lmutil lmstatlmutil- 版权所有(c)1989-2016 Flexera Software LLC。保留所有权利。灵活的许可证管理器状态在Sun 6/17/2018 19:14许可证服务器状态:5280@fpga-centos-6.c.autonomous-173023.internalLicense文件在internal_server_hostname:5280 @ external_server_hostnamelmgrd未运行:许可证服务器计算机已关闭或未响应。 (-96,7:2“没有这样的文件或目录”)查看lmgrd日志,我没有看到任何错误消息。 lmgrd启动正常并启动2个守护进程罚款。我认为所有的港口都是开放的。从lmutil调试开始,我现在猜测服务器的外部主机名与内部主机名不同。否则我现在迷路了。有没有人有任何好主意......非常感谢您的帮助。干杯,菲利普以上来自于谷歌翻译以下为原文Hi, I have service request open on this as well but I thought it would be good to query the community since it's such a peculiar setup which has been mandated by many unfortunate choices. We're trying to run a floating license manager on a google cloud instance and use the floating licenses on a local machine and it's not working. We are running Vivado 2017.4 on a Centos-6 google cloud instance. Google cloud machines are annoying, they have an internal hostname (server_internal_hostname) and and external hostname (server_external_hostname) From outside, you access the machine (ssh, etc) using external_server_hostname, but internally, the machine knows itself as internal_server_hostname. We installed FlexLM 11.14 separatelyWe setup the floating license files (license files use the internal_server_hostname (i.e. SERVER internal_server_hostname)We created a flexlm service which automatically starts lmgrd, it also starts xilinxd (and cdslmd for cadence)The lmgrd is configured to use port 5280 (which is open) On the server machine, I've configured XILINDX_LICENSE_FILE=5280@external_server_hostname Running Vivado 2017.4 works and sees the licenses. At work, we have a local machine, let's call it client_machine. It is running centos7 (we have no choice for other reasons) On client_machine, we have installed Vivado 2018.1 (since 2017.4 won't work on Centos 6)On the client_machine, I configure XILINDX_LICENSE_FILE=5280@external_server_hostname When I run Vivado 2018.1 on the client machine, it is unable to see the licenses. using lmutil: lmutil lmdiaglmutil - Copyright (c) 1989-2016 Flexera Software LLC.

(-96,7:2 "No such file or directory") Looking at the lmgrd logs, I don't see any error messages. lmgrd starts up fine and starts up the 2 daemons fine. I think all the ports are open. From the lmutil debugging, I am now guessing that there is problem with the fact that the server has a different internal hostname from its external hostname. Otherwise I am currently lost. Does anybody have any bright ideas... Thanks very much for your help. cheers,phillip

LT8708是一款效率高达98%的双向降压-升压开关电源控制器,可在两个电压相同的电池之间工作,非常适合用于实现自动驾驶汽车的电池冗余。同时它可以在输入电压高于、低于或等于输出电压的的情况下工作,非常适合用于电动和混动汽车中常见的两个12 V、24 V或48 V电池系统。LT8708工作在两个电池系统之间,即便其中一个电池发生故障,也可以防止系统关闭。LT8708还可以用于48 V/12 V和48 V/24 V双电池系统。

自动驾驶汽车,它们不需要一个人类驾驶员坐在方向盘后面(当然,也许会有一个,但并不是从传统的角度实际使用操控机制)。与之相反,相当于人类驾驶员的微型计算 机主机运行大量的计算机代码,与车辆内外各种不同的传感器阵列相连。它们连接至云,并可以完全实时模拟车辆周围的外 部环境,从而根据当前四周的交通情况预期需要采取的行动。 无论气候、环境和交通条件的范围和状况如何,这些操作都会 正常执行。
