The LogP machine is a model for parallel computation.
[1] It aims at being more practical than the PRAM model while still allowing for easy analysis of computation.
The name is not related to the mathematical logarithmic function: Instead, the machine is described by the four parameters
The LogP machine consists of arbitrarily many processing units with distributed memory.
