A system for variable replacement in a template artificial intelligence (AI) accelerator code. The system includes: at least one memory; at least one processor communicatively coupled to the at least one memory, and configured for computing at least one table of variables from a template AI accelerator code; and an AI accelerator including a plurality of engines, and communicatively coupled to the at least one processor and the at least one memory. The AI accelerator is configured to create a variable replaced AI accelerator code for the plurality of engines of the AI accelerator from the template AI accelerator code by replacing variables in the template AI accelerator code with actual values from the at least one table of variables.

Variable replacement by an artificial intelligence accelerator

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.

Validating memory access patterns of static program code

One or more units of decompressed data of a plurality of units of decompressed data is written to a target location for subsequent writing to memory. The plurality of units of decompressed data includes a plurality of symbol outputs and has associated therewith a plurality of decompression headers. A determination is made that the subsequent writing to memory of at least a portion of another unit of decompressed data to be written to the target location is to be stalled. A symbol start position of the other unit of decompressed data and a decompression header of a selected unit of the one or more units of decompressed data written to the target location are provided to a component of the computing environment. The decompression header is used for the subsequent writing of the other unit of decompressed data to memory.
