Abstract

In one embodiment, a method for sharing bandwidth in a data processing system having a plurality of locations includes splitting data into a plurality of data elements, sending each one of the plurality of data elements to a different location selected from the plurality of locations, wherein each data element is different, and sending a message to each of the locations. In another embodiment, a method for sharing bandwidth in a data processing system having a plurality of locations, wherein the plurality of locations comprises a first location and plurality of further locations, includes receiving a first data element, receiving a message, wherein the message comprises an address of each of the further locations, and sending the first data element to each of the further locations of the plurality of further locations, responsive to determining the address of each of the further locations.

Claims

1. A method for sharing bandwidth in a data processing system having a plurality of locations, the method comprising:

splitting data into a plurality of data elements;

sending each one of the plurality of data elements to a different location selected from the plurality of locations, wherein each data element is different; and

sending a message to each of the locations.

2. The method of claim 1, wherein the data is split into equal size data elements.

3. The method of claim 1, wherein the data elements are sent to each location alternately.

4. The method of claim 1, wherein the message comprises an address of each of the locations of the plurality of locations.

9. A computer program product for performing the method of claim 1, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to split the data into the plurality of data elements;

computer readable program code configured to send each one of the plurality of data elements to a different location selected from the plurality of locations; and

computer readable program code configured to send the message to each of the locations.

5. A method for sharing bandwidth in a data processing system having a plurality of locations, wherein the plurality of locations comprises a first location and plurality of further locations, the method comprising:

receiving a first data element;

receiving a message, wherein the message comprises an address of each of the further locations; and

sending the first data element to each of the further locations of the plurality of further locations, responsive to determining the address of each of the further locations.

6. The method of claim 5, wherein the method further comprises the step of receiving a second data element.

7. The method of claim 6, wherein the method further comprises the step of combining the first data element with the second data element.

8. The method of claim 7, wherein the second data element is received from a different one of the locations than the first data element.

10. A computer program product for performing the method of claim 5, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to receive the first data element;

computer readable program code configured to receive the message; and

computer readable program code configured to send the first data element to each of the further locations of the plurality of further locations.
