Abstract

Disclosed are a method of and system for profiling a computer program. The method comprises the steps of using a utility application to execute the computer program; and on the basis of said execution of the computer program, identifying specific performance requirements of the computer program. A profile of the computer program is determined from said identified performance requirements; and based on said determined profile, resources for the computer program are selected from a grid of computer services.

Claims

1. A method of profiling and selecting grid resources for a computer program to adapt the program to use a specified grid based system of computer services via a grid adapter, the method comprising the steps of:

using a utility application to execute the computer program on a virtual machine running on a computer system;

inserting a wrapper between the utility application and the virtual machine;

said wrapper providing pass-through access to the virtual machine, monitoring operation of the computer program for a period of time, and recording resource use characteristics and patterns of the operation of the computer program to understand the use of grid capable resources that the computer program could utilize and to be cognizant of the way the computer program makes use of resources, including

on the basis of said execution of the computer program, identifying specific performance requirements of the computer program, and

determining a profile of the computer program from the recorded use characteristics and patterns and said identified performance requirements to adapt the computer program to the specified grid based system of computer services via the grid adapter, including using a profiling tool to build an application configuration file for the computer program, and said profile describing a relative priority of the computer program to the grid adapter; and

using said determined profile for selecting resources for the computer program from the grid based system of computer services.

2. A method according to claim 1, wherein said specific performance requirements are selected from the group including:

memory allocation requirements, I/O intensiveness, network usage, CPU, and math operation.

3. A method according to claim 1, wherein the step of selecting resources includes the steps of:

presenting the selection of resources to an administrator; and

said administrator having an option to override any particular selection of resources.

4. A method according to claim 3, wherein the step of selecting resources includes the further step of said administrator defining a relative priority for the distribution of resources from the grid.

5. A method according to claim 1 wherein:

the determining the profile includes the wrapper enabling hooks in a plurality of services to profile the computer program;

the profile describes a plurality of functions of the computer program; and

said relative priority is based on a timeliness of completion of the computer program, a criticalness of the computer program for a business, a frequency of execution of the computer program, and a relative importance to other specified applications.

6. The method according to claim 1, wherein said relative priority is based on a timeliness of completion of the computer program, a criticalness of the computer program for a business, a frequency of execution of the computer program, and a relative importance of the computer program to other specified applications.

7. The method according to claim 1, wherein said profile providing specific data needed to execute the computer program, in an environment of said grid based system, in a best possible way.

8. The method according to claim 1, further comprising virtualizing the entire computer program to run complete copies of the computer program across the grid based system of computer services.

9. The method according to claim 1, wherein:

the determining a profile of the computer program to adapt the computer program to the specified grid based system via the grid adapter includes adapting the computer program to make use of the grid based system without re-coding the computer program; and

the using said determined profile for selecting resources includes using the application configuration file to select the resources from the grid based system of computer services.

10. A system for profiling and selecting grid resources for a computer program to adapt the program to use a specified grid based system of computer services via a grid adapter, the system comprising:

a computer device comprising a memory and at least one processor coupled to the memory and operative for;

using a utility application to execute the computer program on a virtual machine running on a computer system;

inserting a wrapper between the utility application and the virtual machine;

said wrapper providing pass-through access to the virtual machine, monitoring operation of the computer program for a period of time, and recording resource use characteristics and patterns of the operation of the computer program to understand the use of the grid capable resources that the computer program could utilize and to be cognizant of the way the computer program makes use of resources, including

on the basis of said execution of the computer program, identifying specific performance requirements of the computer program, and

determining a profile of the computer program from the recorded use characteristics and patterns and said identified performance requirements to adapt the computer program to the specified grid based system of computer services via the grid adapter, including using a profiling tool to build an application configuration file for the computer program, and said profile describing a relative priority of the computer program to the grid adapter; and

using said determined profile for selecting resources for the computer program from the grid based system of computer services.

11. A system according to claim 10, wherein said specific performance requirements are selected from the group including:

memory allocation requirements, I/O intensiveness, network usage, CPU, and math operation.

12. A system according to claim 10, wherein the selecting resources includes:

presenting the selection of resources to an administrator; and

providing said administrator with an option to override any particular selection of resources.

13. A system according to claim 12, wherein the selecting resources further includes enabling said administrator to define a relative priority for the distribution of resources from the grid.

14. A system according to claim 10, wherein:

the computer program has an associated configuration file that provides application specific data needed to execute the computer program using services from the grid.

15. A program storage hardware device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for profiling a computer program to adapt the program to use a specified grid based system of computer services via a grid adapter, said method steps comprising:

using a utility application to execute the computer program on a virtual machine running on a computer system;

inserting a wrapper between the utility application and the virtual machine;

said wrapper providing pass-through access to the virtual machine, monitoring operation of the computer program for a period of time, and recording resource use characteristics and patterns of the operation of the computer program to understand the use of grid capable resources that the computer program could utilize and to be cognizant of the way the computer program makes use of resources, including on the basis of said execution of the computer program, identifying specific performance requirements of the computer program, and

determining a profile of the computer program from the recorded use characteristics and patterns and said identified performance requirements to adapt the computer program to the specified grid based system of computer services via the grid adapter, including using a profiling tool to build an application configuration file in the computer program, and said profile describing a relative priority of the computer program to the grid adapter; and

using said determined profile for selecting resources for the computer program from the grid based system of computer services.

16. A program storage device according to claim 15, wherein said specific performance requirements are selected from the group including:
