%global _description \
PyFastNoiseSIMD is a wrapper around Jordan Peck's synthetic noise library which \
has been accelerated with SIMD instruction sets. \
\
Parallelism is further enhanced by the use of concurrent.futures to \
multi-thread the generation of noise for large arrays. Thread scaling is \
generally in the range of 50-90%, depending largely on the vectorized \
instruction set used. The number of threads, defaults to the number of virtual \
cores on the system.
