Node including a CPU which is connected to other nodes constituting a computer system

A node that is connected to other nodes to constitute a computer system, the node comprising:

• a CPU configured to execute one or more processes including predetermined functions;
• a shared memory configured to store system information including process information related to each process executed by each node included in the computer system, wherein the system information is stored in the shared memory in a state accessible from each process executed by the CPU;
• and
• a system information transmitter configured to multicast system information including process information related to each process executed by the CPU to the other nodes;
• wherein the CPU is configured to cause the system information multicast received from the other nodes to be stored in the shared memory, and
• wherein the system information stored in the shared memory is shared between the node and the other nodes causing the system information in the shared memory to be identical between the node and the other nodes.

A computer system, comprising:

• a plurality of nodes connected with each other over a network,
• wherein each node of the plurality of nodes comprises:
• a CPU configured to execute one or more processes including predetermined functions;
• a shared memory configured to store system information including process information related to each process executed by each node among the plurality of nodes included in the computer system, wherein the system information is stored in the shared memory in a state accessible from each process executed by the CPU;
• and
• a system information transmitter configured to multicast system information including process information related to each process executed by the CPU to other nodes among the plurality of nodes in the computer system;
• wherein the CPU is configured to cause the system information multicast received from the other nodes to be stored in the shared memory, and
• wherein the system information stored in the shared memory is also stored in the shared memories of the other nodes, and includes the process information related to each process executed by each node among the plurality of nodes in the computer system.
