Abstract
A computer system configured to perform operations for validating memory access patterns of a static variant of a program instruction stream, the operations including randomizing a first set of input arguments, generating an address translation list for virtual addresses based on memory access patterns and storing memory accesses in a first table, and executing the static variant of the program instruction stream on the accelerator processing unit. During execution, the virtual addresses may be discarded and replaced by the addresses provided in the address translation list. The operations may include recording and storing every memory access of executing the static variant of the program instruction stream in a second table and comparing the memory access patterns stored in the second table to memory accesses patterns stored in the first table. Memory access patterns may be validated or discarded.
