Abstract:
1. A method for a local node and a remote node of an interconnect system to communicate via communication links, the method comprising: the local node transmitting a first command packet to the remote node over one of the communication links, the first command packet identifying a direct memory access (DMA) write command for performing an inter-node DMA transfer of a block of data directly from the local node to the remote node via one of the communication links; the local node transmitting a second command packet to the remote node over one of the communication links, the second command packet identifying an administrative write command for writing data from the local node to registers in the remote node via one of the communication links for administrative purposes; the local node transmitting a third command packet to the remote node over one of the communication links, the third command packet identifying a memory copy write command for copying an entire line of memory from the local node to a corresponding line of memory at the remote node via one of the communication links when a new data is written into the line of memory at the local node even when the new data is smaller than the line of memory at the local node; and the local node transmitting a fourth command packet to the remote node over one of the communication links, the fourth command packet identifying a built in self test (BIST) command for testing the functionality of one of the communication links.
