Abstract
TAN PRONTO COMO LOS ORDENADORES (MCA, MCB, MCC) EN UN SISTEMA DE 2 O 3 ORDENADORES ALCANZAN UN PUNTO DE SINCRONIZACION EN SU DESARROLLO DEL PROGRAMA, INTERRUMPEN SU DESARROLLO DEL PROGRAMA Y TRANSMITEN A LOS ORDENADORES SOCIOS SEÑALES DE DISPONIBILIDAD PARA LA SINCRONIZACION (SYA, SYB, SYC). EL DESARROLLO DEL PROGRAMA SE CONTINUA EN TODOS LOS ORDENADORES AL MISMO TIEMPO SI HAY SEÑALES DE DISPONIBILIDAD PARA LA SINCRONIZACION PROCEDENTES DE TODOS LOS TRES ORDENADORES EN LAS UNIDADES DE SINCRONIZACION (BGA, BGB, BGC) ASIGNADAS A ESOS COMPUTADORES. SI UNA SEÑAL DE DISPONIBILIDAD PARA LA SINCRONIZACION (POR EJEMPLO, SYA) ES PERDIDA, ESTO ES RECONOCIDO POR UN MONITOR DE TIEMPO (ZUA3) DE LA UNIDAD DE SINCRONIZACION (MCA) ASIGNADA AL ORDENADOR FUERA DE SINCRONIZACION (MCA), EL CUAL, DESPUES DE UN TIEMPO PREFIJADO, INTERRUMPE EL ACCESO DEL ORDENADOR (MCA) A LA PERIFERIA PERTINENTE DE SEGURIDAD Y TRANSMITE SEÑALES DE DISPONIBILIDAD PARA LA SEUDO-SINCRONIZACION (SYA) A LOS OTROS ORDENADORES (MCB, MCC) QUE DE MODO PERMANENTE SIMULAN LA CAPACIDAD DE SINCRONIZACION DEL ORDENADOR FUERA DE ACCION (MCA). EL SISTEMA DE ORDENADORES CONTINUA ENTONCES TRABAJANDO EN EL MODO 2 DE 2. SI EL MONITOR DE TIEMPO (ZUA3) FALLA, ENTRAN EN ACCION EN TODAS LAS UNIDADES DE SINCRONIZACION OTROS MONITORES DE TIEMPO (ZUA1, ZUA2; ZUB1,ZUB2; ZUC1,ZUC2) AJUSTADOS A TIEMPOS DE RETARDO MAS LARGOS, QUE DESCONECTAN EL SISTEMA DE ORDENADORES.
