作爲encog安裝測試的一部分，我嘗試運行 ./encog benchmark /gpu:0，這工作正常，但是當我嘗試 ./encog benchmark /gpu:1，我得到：如何在運行時修復encog「內核啓動失敗」錯誤：「./encog benchmark/gpu：1」
encog-core/cuda_eval.cu(286) : getLastCudaError() CUDA error : kernel launch failure : (13) invalid device symbol.
我在Ubuntu 11.10，我從https://github.com/encog/encog-c， 得到源代碼，並 「使ARCH = 64 CUDA = 1」 就沒有錯誤了。
感謝您解決此問題的任何幫助。
下面是基準控制檯列表中工作得很好：
