java - 无法在 Windows 7 64 位、Sun JDK 7 和 IntelliJ 11.1 上通过 CUDA 4.0 运行 JCUDA 0.4.1

Question

问题列出了所有相关版本。

我正在尝试运行 http://www.jcuda.org 处的示例文件之一:JCublasMatrixInvert.java。

我已经安装了 NVIDIA CUDA 驱动程序；我已经下载了 JCUDA 0.4.1 绑定(bind)并将其/lib 目录添加到我的 java.library.path 中。以下是我运行时设置的JVM参数:

-ea -XX:+UseParNewGC -XX:+UseNUMA -XX:PermSize=128m -XX:MaxPermSize=256m -Xmx1024m -Djava.library.path=F:\Projects\Java\learning\out\production\learning

然而，当我尝试运行该类时，我得到以下堆栈跟踪:

我可以在路径中看到据称丢失的 dll

F:\Projects\Java\learning\out\production\learning\JCublas-windows-x86_64.dll

我错过了什么？我究竟做错了什么？任何成功运行此示例的人都可以给我建议吗？谢谢。

如果标准方法太难 - 我建议您使用 JCuda 的 mavenized 版本。您可以在此处克隆标准项目 - https://github.com/MysterionRise/mavenized-jcuda它在 Windows/Linux 32/64 位上自动工作

您需要做的就是运行:

• 您需要在此处为​​您的平台安装 Cuda 5.5 - https://developer.nvidia.com/cuda-downloads
• 调用 mvn clean package 构建项目
• 调用 mvn exec:exec 以使用“Hello, JCuda”示例运行主类:)
• 之后，您可以用 JCuda 代码替换主类
