启动G-WAN的问题 [英] Problems to start G-WAN

问题描述

我尝试在Ubuntu 12.04.1 LTS(x64)上安装G-Wan. 我按照快速说明进行操作: http://gwan.com/download

I try to install G-Wan on Ubuntu 12.04.1 LTS (x64). I follow the fast instructions: http://gwan.com/download

当我执行$ sudo ./gwan时，显示给我:

When i execute $sudo ./gwan, shows me:

浮点异常(核心已转储)

Floating point exception (core dumped)

然后，我按照缓慢的说明进行操作: http://www.as2.com/pdf/GWAN-Install-Manual-for-Ubuntu-12.04.pdf

Then i follow the slow instructions: http://www.as2.com/pdf/GWAN-Install-Manual-for-Ubuntu-12.04.pdf

但是我有同样的错误.

我向您显示日志错误:

apport.log

请，有人知道是什么问题吗?

Please, Does anyone know what is the problem?

在我的PC(Ubuntu 12.04.2 LTS)中安装程序并可以正常运行，我不明白，因为在我的PC中可以正常运行，而在服务器中则不能.

Install the program in my PC (Ubuntu 12.04.2 LTS) and works fine, i don't understand because in my PC works fine and in the server not.

谢谢大家，对不起，我的英语不好.

Thanks for all and sorry, my english is bad.

推荐答案

问题是，一些较新版本的系统管理程序坚持要求报告ZERO CPU和/或ZERO CPU Core，导致被零除.

The problem is that some newer versions of hypervisors insist to report ZERO CPU, and/or ZERO CPU Core, leading to a division by zero.

由于G-WAN针对多核体系结构进行了优化，因此它查询CPUID指令和OS内核结构，以检查平台体系结构和相关的OS策略(在线和允许的CPU数量).

Since G-WAN is optimized for multicore architectures, it queries the CPUID instruction and the OS Kernel structures to check the platform architecture and the associated OS policies (number of online and allowed CPUs).

其他Web服务器不会受到影响，因为它们希望用户手动配置并运行所需的任意数量的实例(从而创建G-WAN旨在避免的重复资源分配).

Other web servers are not affected because they expect users to manually configure and run as many instances as desired (hereby creating the duplicated resource allocations that G-WAN was designed to avoid).

检查CPUID指令和内核结构就足够了，直到最近.现在，无论出于何种原因，系统管理程序都会使用损坏的CPUID实现和OS Kernel结构.

Checking both the CPUID instruction and the Kernel structure was enough, until recently. Now, for any reason, the hypervisors use broken CPUID implementations and OS Kernel structure.

此问题正在影响托管公司(VPS服务器)和Amazon EC2实例等.

This issue is affecting hosting companies (VPS servers), and Amazon EC2 instances, among others.
