我在 Windows 7 64x 上使用 VS 2010。
我用以下代码创建了一个静态类 Cuda
namespace Network
{
public static class Cuda
{
static GPGPU gpu= CudafyHost.GetDevice();
static CudafyHost host = new CudafyHost();
static GPGPUBLAS blas = GPGPUBLAS.Create(gpu);
public static void GEMM(int m, int n, int k, float alpha, float[] a, float[] b, float beta, float[] c,Cudafy.Maths.BLAS.Types.cublasOperation Op)
{
float[] d_a = gpu.Allocate(a);
float[] d_b = gpu.Allocate(b);
float[] d_c = gpu.Allocate(c);
gpu.CopyToDevice(a, d_a);
gpu.CopyToDevice(b, d_b);
gpu.CopyToDevice(c, d_c);
blas.GEMM(m, n, k, alpha, d_a, d_b, beta, d_c, Op);
gpu.CopyFromDevice(d_c, c);
gpu.Free(d_a);
gpu.Free(d_b);
gpu.Free(d_c);
}
}
}
我成功地使用了这个 GEMM 函数，但是当我尝试用这样的测试来测试我的代码时
``
namespace TestProject
{
[TestClass]
public class MatrixTest
{
/// <summary>
///op_Multiply
///</summary>
[TestMethod()]
public void op_MultiplyTest()
{
Matrix a = new Matrix(2,3);
a.Data = new float[] { 1, 2, 3, 4, 5, 6 };
Matrix b = new Matrix (3,4);
b.Data = new float[] { 1, 0, 2, 3, 1, 2, 0, 4, 2, 1, 1, 0, 3, 0, 1, 1 };
Matrix expected = new Matrix(2, 4);
expected.Data = new float[] {11,14,16,22,22,28,4,6};
Matrix actual;
actual = (a * b);
Assert.AreEqual(expected, actual);
}
}
}
我得到以下异常：

InnerException:
在我看来，问题在于 IDE 尝试使用 cudafy DLL 两次或两次初始化静态类...
我该如何解决？
===============编辑===============
我试图在我的类 MatrixTest 中使用来自 cudafy dll 的任何函数。嗯，它有效。但不是所有的。例如，Cudafy.Host.CudaGPU.GetDeviceCount() 返回零，就像没有找到支持 cuda 的设备一样。
当我尝试使用像 CudafyHost.GetDeviceCount(eGPUType.Cuda) 或 CudafyHost 类中的任何其他东西时，我得到了上述异常。
