Interprocessor communication measurement system
An interprocessor communication measurement system for an information processing apparatus having a plurality of processors which may send data to the other processors through a plurality of communication channels, includes a socket which is connected with communication channels and electrically connects a processor attached thereto with the communication channels, a measurement node which is attached to the socket in place of the processor and electrically connected with the communication channels, wherein the measurement node includes a routing unit configured to send data destined for any one of the other processors to the one of the other processors through the communication channels and an intercepting unit configured to intercept data sent through the routing unit, and a storing unit configured to store data intercepted by the intercepting unit of the measurement node.
1. An interprocessor communication measurement system for an information processing apparatus having a plurality of processors each of which may send data to other processors through a plurality of communication channels, the interprocessor communication measurement system comprising:
a socket which is connected with the plurality of communication channels and electrically connects a processor of the plurality of processors attached thereto with the plurality of communication channels;
a measurement node which is attached to the socket in place of the processor and electrically connected with the plurality of communication channels, wherein the measurement node includes a routing unit configured to send data destined for any one of the other processors to the one of the other processors through the plurality of communication channels and an intercepting unit configured to intercept data sent through the routing unit; and
a storing unit configured to store data intercepted by the intercepting unit of the measurement node,
wherein the plurality of communication channels individually connect the plurality of processors to each other, and
each processor includes:
a plurality of ports individually connected with the plurality of communication channels;
a routing table configured to define a relation between a destination processor of data and a port from which the data is sent;
a routing unit configured to refer to the routing table to determine a port to send data destined for any one of the other processors and send the data destined for any one of the other processors from the determined port; and
a routing table changing unit configured to rewrite the routing table of each processor as another routing table in which a port connected with one of the plurality of communication channels connecting with the measurement node is defined as a port to send data destined for any one of the other processors.
2. The interprocessor communication measurement system according to claim 1 , wherein:
the measurement node further comprises a measuring unit configured to measure a state of each communication channel connected with the socket; and
the storing unit also stores information about the state of each communication channel measured by the measuring unit.
