Detailed Description

Function Documentation

atomicAdd_d()

__device__ double atomicAdd_d ( double *  address, double  val  )

inline

Atomic addition, which only uses the built-in atomicCAS function.

This function aims at older versions of GPUs, which don't have atomicAdd().

moveSeed()

__device__ void moveSeed ( int &  movingSeed )

inline

Randomizes the given number, which also serves as the random generation seed.

norm1()

__device__ int norm1 ( int3  a )

inline

Returns the norm 1 of an int3 (norm of the absolute value).

operator+()

__device__ int3 operator+ ( int3  a, int3  b  )

inline

Adds two int3.

operator-()

__device__ int3 operator- ( int3  a, int3  b  )

inline

Subtracts two int3.

print()

__device__ void print ( int3  a )

inline

Prints an int3 from within device code.

randomize()

__device__ int randomize ( int &  movingSeed )

inline

A wrapper for moveSeed, which also returns the generated random number.

randomize_d()

__device__ double randomize_d ( int &  movingSeed )

inline

Version of randomize that returns a number in range [0,1].
