A machine instruction is provided that includes an opcode field to provide an opcode, the opcode to identify a perform pseudorandom number operation, and a register field to be used to identify a register, the register to specify a location in memory of a second operand to be used. The machine instruction is executed, and execution includes obtaining a modifier field of a register associated with the machine instruction; based on the modifier field having a first value, performing a deterministic pseudorandom number seed operation, which includes obtaining seed material based on information stored in the second operand; using a 512 bit secure hash technique and the seed material to provide one or more seed values; and storing the one or more seed values in a parameter block. |
