"""
ArrayFire is a high performance scientific computing library with an easy to use API.
>>> # Monte Carlo estimation of pi
>>> def calc_pi_device(samples):
# Simple, array based API
# Generate uniformly distributed random numers
x = af.randu(samples)
y = af.randu(samples)
# Supports Just In Time Compilation
# The following line generates a single kernel
within_unit_circle = (x * x + y * y) < 1
# Intuitive function names
return 4 * af.count(within_unit_circle) / samples
Programs written using ArrayFire are portable across CUDA, OpenCL and CPU devices.
The default backend is chosen in the following order of preference based on the available libraries:
1. CUDA
2. OpenCL
3. CPU
The backend can be chosen at the beginning of the program by using the following function
>>> af.set_backend(name)
where name is one of 'cuda', 'opencl' or 'cpu'.
The functionality provided by ArrayFire spans the following domains:
1. Vector Algorithms
2. Image Processing
3. Signal Processing
4. Computer Vision
5. Linear Algebra
6. Statistics
