Abstract: A request to send a message from a first component, located on a first processor, to a second component, located on a second processor, is received. It is determined that the second processor can be communicated with via a first bidirectional communication path. It is determined that bandwidth is available on the first bidirectional communication path. It is determined that bandwidth is available on a second bidirectional communication path. In response to a determination that bandwidth is available on the second bidirectional communication path, a data path is created between the first component and the second bidirectional communication path and the request to send the message to the second component is granted. In response to a determination that bandwidth is not available on the first bidirectional communication path or on the second bidirectional communication path, the grant of the request to send the message to the second component is delayed.

Abstract: A request to send a first message from a first component to a second component is received at an arbiter. The first component is located in a first time zone and the second component is located in a second time zone. The arbiter determines that the second component is located in the second time zone. It is determined that the second time zone can be communicated with via one or more communications channels in a first direction. It is determined whether bandwidth is available on the one or more communications channels in the first direction. If bandwidth is available on the one or more communications channels in the first direction, a data path between the first component and the one or more communications channels in the first direction is created and the request is granted. Otherwise, the grant of the request is delayed.

Abstract: A computer-implemented method includes storing commands and maintaining an order of receipt of the commands in a command processing unit. The commands include address translation cache miss commands that are organized as one or more linked lists and stored in a content-addressable memory (CAM). All nodes within a single linked list include commands having addresses that map to the same hash value. Based on receiving a memory fetch completion indicator for a cache entry for a command in a head node in a linked list, all of the commands in the linked list are returned. The returning includes sending the commands in the linked list to an address translation unit in an order specified by the linked list.
