About:
Global Arrays (GA) is a Partitioned Global Address Space (PGAS) library that provides an efficient, high-level interface for accessing distributed dense arrays. It enables scientific programmers to manage and manipulate large datasets across multiple nodes in a cluster with a shared-memory style programming model. This approach significantly simplifies the development of scalable, high-performance computing applications.

Key Features:

PGAS programming model for distributed memory
Support for Fortran and C/C++ interfaces
Optimized for high-performance computing (HPC) workloads
Explicit data locality control for performance tuning
Scalable to thousands of processor cores

Use Cases:

Large-scale scientific simulations (e.g., quantum chemistry, astrophysics)
Big data analytics on high-performance computing clusters
Machine learning model training on distributed memory systems

Alternatives:

MPI – GA provides a higher-level, array-centric abstraction compared to MPI's lower-level message passing primitives.
Chapel – GA is a library usable from existing languages, whereas Chapel is a standalone language with built-in PGAS features.
