Abstract
A method for generating an executable program to run on one or more processor modules. The method comprises: receiving a graph comprising a plurality of data nodes, compute vertices and edges; and compiling the graph into an executable program including one or more types of multi-access instruction each of which performs at least two memory access (load and/or store) operations in a single instruction. The memory on each processor module comprises multiple memory banks whereby the same bank cannot be accessed by different load or store operations in the same instruction. The compilation comprises assigning instances of the multi-access instructions to implement at least some of the graph edges, and allocating the data to memory addresses within different ones of the banks. The allocating is performed subject to one or more constraints, including at least that different load/store operations should not access the same memory bank in the same instruction.
