Abstract

A cluster system based on a parallel computing framework is provided, and the cluster system includes a host node configured to execute a host program for a parallel computing framework and a computing node configured to be connected to the host node and execute a kernel program for the parallel computing frame work.

First claim

What is claimed is:

1. A cluster system based on a parallel computing framework, the cluster system comprising:
a host node configured to execute a host program for a parallel computing framework; and
a computing node configured to be connected to the host node via a network and execute a kernel program for the parallel computing framework,
wherein the host node comprising a processor configured to execute a host thread,
wherein the host thread is configured to execute a host program for a parallel computing framework and to insert a command related to a kernel program in a command-queue which corresponds to a remote computing module capable of executing the kernel program or the parallel computing framework and a command scheduler configured to select a command to be executed by scheduling the command-queue, generate a request message to request execution of the selected command and transmit the request message to a computing node via a network,
wherein the command scheduler, in response to receiving the request message, stores the selected command in an issue-queue, and, in response to receiving from the computing mode a completion message to notify that execution of the command has been completed, deletes the command stored in the issue-queue, and
wherein the computing node comprises one or more computing modules to execute the kernel program.

2. The cluster system of claim 1 , wherein the host node generates a request message to request execution of a command related to the kernel program, and transmits the generated request message to the computing node via the network.

3. The cluster system of claim 2 , wherein the computing node execute the command in response to the request message, generates a completion message to notify execution of the command is completed, and transmit the generated completion message to the host node via the network.

4. The cluster system of claim 1 , wherein the host node comprises one or more command-queues respectively corresponding to the one or more computing modules.

5. The host node of claim 1 , wherein, in the case of where a number of computing modules are provided, one or more command-queues are formed corresponding to the number of computing modules.

6. The computing node of claim 1 , the computing node further comprising:
a command handler processor configured to receive a request message indicating a request for execution of a command related to a kernel program for a parallel computing framework from a remote host node which executes a host program, in response to the request message, generate a command object, and insert the generated command object in a ready-queue corresponding to the computing modules; and
a module thread processor configured to execute the command using the command object inserted in the ready-queue and the computing modules.

7. The computing node of claim 6 , wherein, when execution of the command has been completed, the command handler generates a completion message to notify that execution of the command has been completed, and transmits the generated completion message to the remote host node via the network.
