Abstract

This power-on data processing machine check technique is operative in a multiprogrammed, parallel multi-processor system to allow operation of the system when (a) a minimum acceptable system hardware configuration exists, (b) all processors in the system are able to check themselves and their system interaction, and (c) no accidental operator errors are present.

Power on Machine Check for Multiprocessor System

This power-on data processing machine check technique is operative in a multiprogrammed, parallel multi-processor system to allow operation of the system when (a) a minimum acceptable system hardware configuration exists,
(b) all processors in the system are able to check themselves and their system interaction, and (c) no accidental operator errors are present.

In an architecture in which multiple processors of varying applications and architecture interface to the a common data memory, the minimum acceptable system hardware configuration requirements are: common data memory with a machine language program.

2. A central processor to interpret the program.

3. A keyboard/cathode ray tube display controller processor

to provide an operator interface to the system

through the keyboard/display unit.

After it has been established that the minimum system configuration exists, the operation of the remainder of the processors in the system and their interaction with the system are checked. The central processor and the keyboard/display processor which are included in the minimum system configuration hardware are utilized in checking and confirming to the operator the operation of the remainder of the processors. The test for accidental operator errors is satisfied by media checks at the IPL device to test for the loading, with no errors, of a valid IPL media and program. A configuration check is also made to ensure that th...
