#CUDA DIM3 CONSTRUCTOR HOW TO#
#CUDA DIM3 CONSTRUCTOR CODE#

I would be clear where the configuration of the threads has been defined, and the 1D, 2D and 3D access pattern depends on how you are interpreting your data and also how you are accessing them by 1D, 2D and 3D blocks of threads. To sumup, it does it matter if you use a dim3 structure. Int y = blockIdx.y * blockDim.y + threadIdx.y Д«ecause blockIdx.y and threadIdx.y will be zero. So, in both cases: dim3 blockDims(512) and myKernel>(.) you will always have access to threadIdx.y and threadIdx.z.ДЄs the thread ids start at zero, you can calculate a memory position as a row major order using also the ydimension: int x = blockIdx.x * blockDim.x + threadIdx.x The same happens for the blocks and the grid.

It can also be used in any user code for holding values of 3 dimensions. Its most common application is to pass the grid and block dimensions in a kernel invocation. Dim3 public Dim3 (int x) Creates a cube of dimension (x,1,1). dim3 is an integer vector type that can be used in CUDA code. When defining a variable of type dim3, any component left unspecified is initialized to 1. 3 public final class Dim3 extends Object. However, the access pattern depends on how you are interpreting your data and also how you are accessing them by 1D, 2D and 3D blocks of threads.Дim3 is an integer vector type based on uint3 that is used to specify dimensions. The memory is always a 1D continuous space of bytes. Your Neuron class will inherent from NeuronVC and your Synapse class will inherent from SynapaseVC.The way you arrange the data in memory is independently on how you would configure the threads of your kernel. Then your definitions (class statements) for for Neuron and Synapse would define variables to these Parent Virtual classes.

I think you will have to create Parent Virtual classes for вЂsynapaseвЂ™ and вЂneuronвЂ™ without the dependency.ДЇor now call these classes вЂSynapseVCвЂ™ and вЂNeuronVCвЂ™

It has been a while since I programmed in C++ so I donвЂ™t know how to get around the problem of dependent definitions. I believe the problem is that your definitions are dependent on each other. вЂ¦Then in SynapsesH.cu (Line20) declares _outputNuron as a pointer to Neuron, which is not yet defined. вЂ¦When SynapseH.cu is included, at line 5 it tries to include NeuronH.cu, but since NEURONH_CU is defined nothing is included.

When NeuronH.cu compiles it defines (line 2) NEURONH_CU, then includes (line 5) SynapseH.cu.

I am new to CUDA & VisualStudio, but I see you including.
