Method for supervising parallel processes

摘要

The present invention relates to a method of supervising parallel processors in a data system that comprises a first system CP-A and a second system CP-B. The method comprises the steps of:generating a first status word STWA in the first system CP-A and a parallel second status word STWB in the second system CP-B;generating in the first system CP-A a first check code CCA from the first status word STWA;generating in the second system CP-B a second check code CCB from the second status word STWB;sending the first check code CCA from the first system CP-A to the second system CP-B; andrecreating the first data word STWA in the second system CP-B by evaluating the first check code CCA, the second check code CCB and the second data word STWB.
