Abstract

Claims (40)

1. A method for execution by a computing core, the method comprises:

detecting selection of an application;

determining whether at least a portion of the application and configuration information regarding the application are currently stored in main memory of the computing core;

when the at least a portion of the application and configuration information regarding the application are not currently stored in main memory, addressing a distributed application memory to retrieve a plurality of error coded program data slices and a plurality of error coded configuration data slices, wherein the addressing includes:

addressing a first memory of the distributed application memory to retrieve a threshold number of error coded program data slices of the plurality of error coded program data slices; and

when less than the threshold number of the error coded program data slices are received from the first memory, addressing a second memory of the distributed application memory to retrieve at least one more error coded program data slices of the plurality of error coded configuration data slices;

reconstructing a data segment of the at least a portion of the application from the plurality of error coded program data slices using an error coding dispersal function;

reconstructing a data segment of the configuration information from the plurality of error coded configuration data slices using a second error coding dispersal function, wherein the configuration information includes at least one of application configuration parameters regarding the application and user preferences regarding the application; and

storing the data segment of the at least a portion of the application and the data segment of the configuration information in the main memory.

2. The method of claim 1 , wherein the second error coding dispersal function is substantially the same as the error coding dispersal function.

3. In the method of claim 1 further comprises:

detecting a change in the configuration information;

when a change is detected in the configuration information, updating the configuration information to produce updated configuration information; and

facilitating storage of the updated configuration information in the distributed application memory.

4. In the method of claim 1 , the addressing of the distributed application memory comprises one or more of:

addressing at least one of a plurality of non-local memory devices;

addressing at least one of a plurality of local area network (LAN) memory devices; and

addressing at least one of a plurality of wide area network (WAN) memory devices.

5. A computing core comprises:

a processing module;

main memory; and

a memory controller, wherein:

the processing module detects selection of an application;

at least one of the memory controller and the processing module:

determines whether at least a portion of the application and configuration information regarding the application are currently stored in main memory of the computing core;

when the at least a portion of the application and configuration information regarding the application are not currently stored in main memory, addresses a distributed application memory to retrieve a plurality of error coded program data slices and a plurality of error coded configuration data slices, wherein the addressing includes:

addressing a first memory of the distributed application memory to retrieve a threshold number of error coded program data slices of the plurality of error coded program data slices; and

when less than the threshold number of the error coded program data slices are received from the first memory, addressing a second memory of the distributed application memory to retrieve at least one more error coded program data slices of the plurality of error coded configuration data slices;

reconstructs a data segment of the at least a portion of the application from the plurality of error coded program data slices using an error coding dispersal function; and

reconstructs a data segment of the configuration information from the plurality of error coded configuration data slices using a second error coding dispersal function, wherein the configuration information includes at least one of application configuration parameters regarding the application and user preferences regarding the application; and

the main memory stores the data segment of the at least a portion of the application and the data segment of the configuration information.

6. In the computing core of claim 5 , wherein the second error coding dispersal function is substantially the same as the error coding dispersal function.

7. In the computing core of claim 5 further comprises:

detecting, by the at least one of the memory controller and the processing module, a change in configuration information;

when a change is detected in configuration information, by the at least one of the memory controller and the processing module, updating, by the at least one of the memory controller and the processing module, the configuration information to produce updated configuration information; and

facilitating, by the at least one of the memory controller and the processing module, storage of the updated configuration information.

8. In the computing core of claim 5 , wherein the at least one of the memory controller and the processing module address the distributed application memory by one or more of:

addressing at least one of a plurality of non-local memory devices;

addressing at least one of a plurality of LAN memory devices; and

addressing at least one of a plurality of WAN memory devices.
