“'Found more than one basic block without predecessors.” with my alea/c# code, and I do not have any idea...












2















So I am trying to implement some code with Alea/C#. For the moment, it is basic code. I tried the tutorials and examples available at the Alea site. The examples work just fine, but when I do my own version of codes, namely, using a random walk with a dynamically defined amount of steps for each walk, it does not seem to work.



I set up an double array as follows and initialize it to 0:



 [GpuParam] public static double gaussian = {0};


I then use a gpumanaged method:



[GpuManaged]
private static void Random()
{
using (var rng = Generator.CreateGpu(Gpu.Default,RngType.PSEUDO_XORWOW))
{
rng.SetPseudoRandomGeneratorSeed(42);

rng.GenerateUniform(gaussian);
}
}


I then use the parallel for function which there is a plethora of examples on the alea website.



    [GpuManaged]
private static void Test()
{
var prices = new double[100];

Gpu.Default.For(0, 100,
i =>
{
Random();
prices[i] = gaussian[0];
});
}


However, when I run this, I get the error:



System.Exception: 'Found more than one basic block without predecessors.


Source location stack:



-> in C:Userstub08918sourcereposGpuMCOpticsGpuMCOpticsProgram.cs(45,21-45,30)

-> Argument.#2: System.Action`1[System.Int32]


Any help on this would be helpful. I am very interested in using these gpu architectures but I have been working on solving this problem all day and I am getting more and more confused as I try different methods such as launching kernels and actions and using shared memory, but none of it works.
