Program event recording storage alteration processing for a neural network accelerator instruction

A computer system for facilitating processing within a computing environment, the computer system comprising:

• a memory;
• and
• at least one processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
• performing instruction processing for an instruction, the instruction configured to perform a plurality of functions, wherein a function of the plurality of functions is to be performed in a plurality of processing phases, wherein a processing phase of the plurality of processing phases is defined to store up to a select amount of data, the select amount of data being based on the function of the plurality of functions to be performed, wherein at least one function of the plurality of functions has a different value for the select amount of data than at least one other function of the plurality of functions;
• determining whether a store into a designated area occurred based on processing a select processing phase of the plurality of processing phases of a select function;
• presenting an interrupt, based on determining that the store into the designated area occurred;
• and
• continuing with performing instruction processing, based on determining that the store into the designated area did not occur.

A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:

• performing instruction processing for an instruction, the instruction configured to perform a plurality of functions, wherein a function of the plurality of functions is to be performed in a plurality of processing phases, wherein a processing phase of the plurality of processing phases is defined to store up to a select amount of data, the select amount of data being based on the function of the plurality of functions to be performed, wherein at least one function of the plurality of functions has a different value for the select amount of data than at least one other function of the plurality of functions;
• determining whether a store into a designated area occurred based on processing a select processing phase of the plurality of processing phases of a select function;
• presenting an interrupt, based on determining that the store into the designated area occurred;
• and
• continuing with performing instruction processing, based on determining that the store into the designated area did not occur.
