Abstract
The invention concerns a High-Performance Computer that includes a plurality of nodes. Each node waits for a first time period after sending a packet, and retransmits the packet if an acknowledgement for the packet has not been received in the first time period. Each node also periodically sends a heartbeat message to each other node having a pending transaction with the node, waits for a second time period after sending a heartbeat message, and aborts the pending transaction if an acknowledgement for the heartbeat message has not been received in the second period. When receiving a negative acknowledgement after sending a packet, the each node retransmits the packet after a third time period starting from the reception of the negative acknowledgement, waits for a fourth time period and drop a packet if the node is congested during the fourth period, and sends a negative acknowledgement message.
