This is a present of the end of year for Elixir programmers from me: The new package “Pelemay Fast Parallel map” has been released! It drives multi cores and is 3x faster than Enum! Check it out, soon!

Pelemay Fast Parallel map (or pelemay_fp) - Fast parallel map function for Elixir

• pelemay_fp | Hex
• GitHub - zeam-vm/pelemay_fp: Fast parallel map function for Elixir · GitHub
• PelemayFp — PelemayFp v0.1.0

Pelemay Fast Parallel map: provides fast Parallel map function, similar to the Enum module, although computations will be executed in parallel using Process.spawn/4.

Here is a quick example on how to calculate the square of each element with PelemayFp:

list
|> PelemayFp.map(& &1 * &1)

We conducted performance evaluation of PelemayFp, Pelemay, Flow, Enum and Pmap on iMac Pro (2017):

## PelemayFpBench
benchmark name          iterations   average time 
PelemayFp                      200   10177.85 µs/op
Pelemay                        100   16762.24 µs/op
PelemayFp and Pelemay          100   18532.70 µs/op
Flow (without sorting)         100   18731.43 µs/op
Enum                            50   31283.36 µs/op
Flow (with sorting)             10   105091.00 µs/op
Pmap                             1   1213749.00 µs/op

Thanks! A happy new year!
