asp.net-mvc - 是否可以在 Azure 上部署 WebRole，并使用 Cloud Numerics 进行计算？

Question

是否可以在 Azure 上使用 Code Numerics 仅进行标准差等计算，而不使用其分布式功能并绕过 HPC？我正在使用一些强大的数学和图表来测试 MVC Web 角色，我添加了对 Cloud Numerics 程序集的引用，整个过程在模拟器中运行(只是一些计算，没有分布式的东西)，但是当我部署到 Azure 时，它​​报告了与 Cloud 的依赖关系问题数字dll？我真的很感激一些建议。 (我知道最好使用一些标准数学库，但我真的需要知道这种方式是否可行)。我最初认为这可能是架构问题:整个项目是 AnyCpu(它只能是 AnyCpu 或 x64，因为 Azure 只允许这两个配置)并且一些 CLoud Numerics 库是为 x64 编译的。但我的开发机器是 x64 win 7，我重复一遍:它可以在模拟器中运行，但不能在云中运行。

所提到的 dll Microsoft.Numerics.DistributedDenseArrays 自然地作为副本包含在内，始终与依赖项遍历工具中所述的其他依赖项一起包含在内。

如果我偶然发现此类问题，我的第一个检查是引用的库是否具有属性 copy local = true。下一步是实现配置诊断如果您仅部署到一个实例进行开发和测试，则可以使用 RDP 来检查事件日志。

阅读Introducing Microsoft Codename “Cloud Numerics” from SQL Azure Labs在先决条件一章中 Microsoft Visual C++ 2010 SP1 Redistributable Package (x64)是需要的。这不是在 Windows Azure 提供的基本 VM 上标准实现的。该软件包可以通过启动任务安装在您的实例上。确保 msi 以静默模式启动(无需用户交互)。
