CLUSTEREASY: A Program for Simulating Scalar Field Evolution on Parallel Computers

Understand

We describe a new, parallel programming version of the scalar field simulation program LATTICEEASY.

• The new C++ program, CLUSTEREASY, can simulate arbitrary scalar field models on distributed-memory clusters.
• The speed and memory requirements scale well with the number of processors.
• As with the serial version of LATTICEEASY, CLUSTEREASY can run simulations in one, two, or three dimensions, with or without expansion of the universe, with customizable parameters and output.
