Abstract
A system and method for load-balancing routing of a computation within a multiprocessor system. The computation includes multiple branches of execution, not just a linear sequence of steps, and thus cannot be efficiently routed by existing minimum-delay routing schemes. The cost of a single step of the computation is calculated, possibly using a ratio of outgoing data rates from the step to the incoming data rate. That cost may then be scaled for different branches of execution of the computation leading to or from that single step. For example, the calculated cost may be multiplied by each branch's probability of being executed.
