Directed route load/store packets for distributed switch initialization

A computer-readable storage medium containing computer-readable program code that, when executed, performs an operation for transmitting a packet from a source switch module to a destination switch module, comprising:

• determining, at the destination switch module, a path from the source switch module to the destination switch module;
• transmitting, from the destination switch module to the source switch module, path information specifying the determined path from the source switch module to the destination switch module;
• receiving, at the destination switch module, from the source switch module, a packet that includes (i) at least a portion of the path information and (ii) payload data to be processed at the destination switch module, wherein the packet was routed using the at least a portion of the path information;
• and
• processing, by the destination switch module, the payload data within the received packet.

A system, comprising:

• a processor;
• and
• a memory containing a program that, when executed by the processor, performs an operation for transmitting a packet from a source switch module to a destination switch module, comprising:
• determining, at the destination switch module, a path from the source switch module to the destination switch module;
• transmitting, from the destination switch module to the source switch module, path information specifying the determined path from the source switch module to the destination switch module;
• receiving, at the destination switch module, from the source switch module, a packet that includes (i) at least a portion of the path information and (ii) payload data to be processed at the destination switch module, wherein the packet was routed using the at least a portion of the path information;
• and
• processing, by the destination switch module, the payload data within the received packet.
