systems and apparatus are described for all - to - all interconnect fabric generated monotonically increasing transaction identifiers . a method includes usage of an all - to - all interconnect fabric generated monotonically increasing transaction identifier to coordinate timing of events on an all - to - all interconnect fabric wherein a ) multiple computer elements share the interconnect fabric , b ) additional nodes add to total system bandwidth , c ) all nodes see all messages from all nodes and any one node can send a message to all nodes with a single command and d ) a single failing transmitter effects only the communication of that node .
