如何在运行时修复“内核启动失败”错误：“./ encog benchmark / gpu：1”

时间：2013-05-08 14:29:09

标签： encog

作为encog安装测试的一部分，我尝试了运行 ./encog benchmark /gpu:0，工作得很好，但是当我尝试的时候 ./encog benchmark /gpu:1，我得到了：

encog-core/cuda_eval.cu(286) : getLastCudaError() CUDA error : kernel launch failure : (13) invalid device symbol.

我在Ubuntu 11.10上，我从https://github.com/encog/encog-c获得了源代码， 并且“make ARCH = 64 CUDA = 1”没有错误。

感谢您解决此问题的任何帮助。

以下是适用于基准测试的控制台列表：

我尝试在我的GeForce 580上运行，没问题。我和6个系列的平台不同。我在Google的几个地方查找了错误。看起来可能是本地内存使用方式的问题，可能不适用于6系列。可能想在这里提交一个问题：
