Abstract

A system for managing Java threads to decrease the time expended by a central processing unit executing any instructions that will manage threads. I/O operations are offloaded to a serial processor. General computing streams are primarily processed in parallel operations.

Claims

1. A thread controller in a processor comprising:

a processor separating general computing operations and I/O processing threads, a separate processor to process I/O threads, said separate processor being connected to said I/O processor, and said I/O processor interconnecting with an input/output unit.

2. The thread controller according to claim 1 wherein said input/output unit comprises networking interface cards and disk controllers.

3. The thread controller according to claim 1 wherein said I/O processor comprises a Java co-processor.

4. The thread controller according to claim 1 wherein said I/O processor comprises a dedicated processor within said first processor.

5. The thread controller according to claim 1 wherein said first processor measures I/O activity in comparison to a pre-selected threshold and interconnects first processor and said I/O processor to release the I/O processor from dedicated I/O processing and said I/O activity is below a pre-selected threshold.

6. A method comprising:

receiving a plurality of computer instructions to be performed;

separating general computing instructions from I/O functions;

providing said I/O instructions to a separate processor to be processed; and

operating input/output devices in communication with said I/O processor.

7. The method according to claim 6 wherein said computing instructions are processed in parallel form and said I/O instructions are processed in serial fashion.

8. The method of claim 7 wherein providing said I/O instructions to a processor comprises providing said instructions to a Java co-processor.

9. The method according to claim 7 wherein providing said instructions to an I/O processor comprises providing said instructions to a dedicated processor in a main CPU.

10. The method according to claim 7 further comprising partitioning a software stack to process the instructions into general computing and I/O sections.

11. The method according to claim 10 further comprising monitoring I/O activity and releasing the I/O processor from dedicated I/O service when I/O activity is below a pre-selected threshold.

12. A machine-readable medium that provides instructions which, when executed by a processor, cause said processor to perform operations comprising:

receiving a plurality of computer instructions to be performed;

separating general computing instructions from I/O functions;

providing said I/O instructions to a separate processor to be processed; and

operating input/output devices in communication with said I/O processor.

13. A machine-readable medium according to claim 12 that provides instructions which when operated by a processor said computing instructions are processed in parallel form and said I/O instructions are processed in serial fashion.

14. A machine-readable medium according to claim 13 that provides instructions which, when executed by a processor, cause said processor to perform operations wherein providing said I/O instructions to a processor comprises providing said instructions to a Java co-processor.

15. A machine-readable medium according to claim 13 that provides instructions which, when executed by a processor, cause said processor to perform operations wherein providing said instructions to an I/O processor comprises providing said instructions to a dedicated processor in a main CPU.

16. A machine-readable medium according to claim 13 that provides instructions which, when executed by a processor, cause said processor to perform operations comprising partitioning a software stack to process the instructions into general computing and I/O sections.

17. A machine-readable medium according to claim 13 that provides instructions which, when executed by a processor, cause said processor to perform operations further comprising monitoring I/O activity and releasing the I/O processor from dedicated I/O service when I/O activity is below a pre-selected threshold.
