  3. Introduction(1/2) • Nowadays, local area or campus-type networks consist of PCs using different operating systems, including Windows and Linux. • To build a largescale grid environment, PCs in offices and laboratories are expected to be used as computational resources in addition to dedicated conventional PC clusters.

  4. Introduction(2/2) • This paper has designed and implemented an agent called BEE, which enables direct execution of Linux binary programs on Windows for a Grid RPC worker. • This paper has integrated the BEE agent into an OmniRPC system in order to make use of Windows PCs as computing resources in a hybrid grid environment combining Windows PCs into grid computing resources.

  5. Hybrid Grid Environment: Executing Linux Programs On Windows(1/3)

  6. Hybrid Grid Environment: Executing Linux Programs On Windows(2/3) • Flexibility: Windows users (PC owners) can work as usual while the worker program runs. If possible, the program should run with low priority, or only when the PC is idle. • Efficiency and Performance: When running the worker program, the execution should be nearly as fast as native ported binary.

  7. Hybrid Grid Environment: Executing Linux Programs On Windows(3/3) • Manageability: The user can setup the environment and prepare the program running in Windows with minimal cost. • Using cross-platform compilers such as Cygwin • Using virtual machine software such as VMware

  8. Design And Implementation Of The BEE Agent(1/5) The BEE has two functions: • The binary program loader • It is a function by which to load a Linux binary program into the Windows memory address space. • The system call emulator. • The system call emulator is a function by which to emulate Linux system calls.

  9. Design And Implementation Of The BEE Agent(2/5)

  10. Design And Implementation Of The BEE Agent(3/5) BEE executes the Linux binary program in following steps: • 1) Before executing the Linux binary program, the interrupt handler for the software interrupt 0x80 of the Linux system is called by using the device driver in the IDT. • 2) The binary program loader loads the specified binary into its own address space and runs as a Windows process. • 3) When a system call occurs during execution, the registered interrupt handler is invoked.

  11. Design And Implementation Of The BEE Agent(4/5) • 4) The interrupt handler returns the control to the system call emulator in BEE. • 5) BEE emulates the system call and returns control to the caller of the system call to continue the execution. • 6) When the exit() system call is called, BEE terminates.

  12. Design And Implementation Of The BEE Agent(5/5)

  13. Integration Of BEE Into The OmniRPC System(1/5)

  14. Performance Of Hybrid Grid Environment Using BEE(2/5)

  15. Performance Of Hybrid Grid Environment Using BEE(3/5)

  16. Performance Of Hybrid Grid Environment Using BEE(4/5)

  17. Performance Of Hybrid Grid Environment Using BEE(5/5)

  18. Conclusion • The paper proposed a mechanism that utilizes Windows PCs as workers of a Grid RPC system in a hybrid grid environment that contains Windows and Linux PCs. • It has designed and implemented an agent called BEE that consists of a binary program loader and a system call emulator to enable a worker program imported from Linux to run under Windows.
