GPUIterator

iter GPU(c: range(?), GPUCallBack: func(int, int, int, void), CPUPercent: int = 0)
Arguments

  • c : range(?) – The range to iterate over. The length of the range must be greater than zero.

  • GPUCallBack : func(int, int, int, void) – The reference to a Chapel function that is invoked after the iterator has computed a subrange for the GPU portion. It must take three integers: lo:int, hi:int, n:int, where lo and hi are the lower and the upper bound of the GPU portion respectively, and n is hi-lo+1.

  • CPUPercent : int – The percentage of the iteration space will be executed on the CPU. The default number for it is zero, meaning the whole itreration space goes to the GPU side.

Yields

Indices in the CPU portion of the range c.

iter GPU(D: domain, GPUCallBack: func(int, int, int, void), CPUPercent: int = 0)
Arguments

  • D : domain – The domain to iterate over. The length of the range must be greater than zero. It must be a rectangular domain. Also, if D is dmapped, it must be BlockDist.

  • GPUCallBack : func(int, int, int, void) – The reference to a Chapel function that is invoked after the iterator has computed a subrange for the GPU portion. It must take three integers: lo:int, hi:int, n:int, where lo and hi are the lower and the upper bound of the GPU portion respectively, and n is hi-lo+1.

  • CPUPercent : int – The percentage of the iteration space will be executed on the CPU. The default number for it is zero, meaning the whole itreration space goes to the GPU side.

Yields

Indices in the CPU portion of the range D.
