Isolates are separate Dyalog APL processes that communicate by message passing. Use them for coarse-grained CPU-bound array work without shared memory, locks, or threading complexity.
Array Dimensionality and Rank Control APL employs rank polymorphism to allow a single function to operate across arrays of varying dimensions. While scalar expansion handles basic broadcasting, precise control over the axis of operation is required when applying functions to higher-order tensors without flattening the data structure. The goal is to maintain
