Abstract
Approaches for synchronizing memory accesses in a dataflow computing system. A compute operation in the dataflow computing system is commenced in response to availability in a dataflow memory of each operand that is required to perform the compute operation. Output data from a compute operation is stored in the dataflow memory at completion of the compute operation. Write and read operations are supported for accessing an external memory. Accesses to the external memory are synchronized by storing synchronization tokens in the data flow memory. Each synchronization token signals when an address in the external memory may be accessed.
