PyCUDA Examples

A collection of PyCUDA examples, originally made for PyCON DK. Refer to the PyCUDA wiki page for more examples.

Examples with explanations:

numpy_simple.py

Double the values in a signed integer array (CPU performance reference)

pycuda_simple1.py

Double the values in a signed integer array using explicit memory allocations and transfers.

pycuda_simple2.py

Same as pycuda_simple1.py, but using pycuda.driver functions for memory transfers.

pycuda_simple3.py

Same as pycuda_simple1-2.py, but using pycuda.driver.InOut.

pycuda_gpuarray.py

Same as the three previous examples, using pycuda.gpuarray.gpuarray.

pycuda_reduction.py

Maximum-reduction of an array using pycuda.reduction.ReductionKernel.

pycuda_exclusive_scan.py

Perform an exclusive scan on an array using pycuda.scan.ExclusiveScanKernel.

pycuda_saxpy.py

Perform a saxpy computation using the gpuarray object.
