Abstract

A distributed computing system includes at least first and second distinct computers each having a different operating system. First processes are compatible with the first operating system and second processes are compatible with the second operating system. A third scheduling computer, coupled to the first and second computer via a communication network, includes a scheduler for scheduling the first processes and the second processes to execute respectively on the first and second computers. The scheduler accesses a master schedule that defines an executing sequence of the first processes and the second processes. The master schedule can define conditional inter-relationships between the first processes and the second processes.

Claims

1. A computer-based method of scheduling executions of programs on a plurality of computers comprising, at a third computer:

receiving a first notification from a first computer upon the installation of a first program on the first computer;

receiving a second notification from a second computer upon the installation of a second program on the second computer, wherein the operating system of the second computer is different from the operating system of the first computer;

updating a master schedule in response to the first and the second notifications and based on the first and the second notifications, wherein the updated master schedule indicates when the first program is to be executed on the first computer, when the second program is to be executed on the second computer, and that an execution of the second program depends on an execution of the first program meeting a criterion; and

requesting the first computer to execute the first program;

receiving a result from the first computer, wherein the result is based on the execution of the first program; and

requesting the second computer to execute the second program according to the updated master schedule and if the result meets the criterion.

2. The method of claim 1, wherein the updating further comprises indicating in the master schedule that the execution of the first program depends on a condition;

and the requesting the first computer further comprises requesting the first computer to execute the first program upon the occurrence of the condition.

3. The method of claim 1, further comprising:

monitoring the load of the first computer;

monitoring the load of the second computer; and

adjusting the updated master schedule based on the load of the first computer and the load of the second computer.

4. The method of claim 1, wherein the updating further comprises assigning a first priority to the first program and a second priority to the second program;

and further comprising adjusting the updated master schedule based on the first priority and the second priority.

5. The method of claim 1, wherein the updating further comprises accepting at least one command from a user to define the updated master schedule.

6. A system for scheduling executions of programs on a plurality of computers comprising a third computer networked to a first computer and a second computer, wherein the third computer comprises:

means for receiving a first notification from a first computer upon the installation of a first program on the first computer;

means for receiving a second notification from a second computer upon the installation of a second program on the second computer, wherein the operating system of the second computer is different from the operating system of the first computer;

means for updating a master schedule in response to the first and the second notifications and based on the first and the second notifications, wherein the updated master schedule indicates when the first program is to be executed on the first computer, when the second program is to be executed on the second computer, and that an execution of the second program depends on an execution of the first program meeting a criterion;

means for requesting the first computer to execute the first program;

means for receiving a result from the first computer, wherein the result is based on the execution of the first program; and

means for requesting the second computer to execute the second program according to the updated master schedule and if the result meets the criterion.

7. The system of claim 6, wherein the means for updating further comprises means for indicating in the updated master schedule that the execution of the first program depends on a condition;

and the means for requesting the first computer further comprises means for requesting the first computer to execute the first program upon the occurrence of the condition.

8. The system of claim 6, further comprising:

means for monitoring the load of the first computer;

means for monitoring the load of the second computer; and

means for adjusting the updated master schedule based on the load of the first computer and the load of the second computer.

9. The system of claim 6, wherein the means for updating further comprises means for assigning a first priority to the first program and a second priority to the second program;

and the means for requesting the first computer further comprises means for adjusting the updated master schedule based on the first priority and the second priority.

10. The system of claim 6, wherein the means for updating further comprises means for accepting at least one command from a user to define the updated master schedule.

11. A computer program product comprising a tangible computer useable storage having computer readable program code embedded in the storage for causing an application program to execute on a third computer that schedules executions of programs on a plurality of computers comprising:

a first computer readable program code for receiving a first notification from a first computer upon the installation of a first program on the first computer;

a second computer readable program code for receiving a second notification from a second computer upon the installation of a second program on the second computer, wherein the operating system of the second computer is different from the operating system of the first computer;

a third computer readable program code for updating a master schedule in response to the first and the second notifications and based on the first and the second notifications, wherein the updated master schedule indicates when the first program is to be executed on the first computer, when the second program is to be executed on the second computer, and that an execution of the second program depends on an execution of the first program meeting a criterion;

a fourth computer readable program code for requesting the first computer to execute the first program;

a fifth computer readable program code for receiving a result from the first computer, wherein the result is based on the execution of the first program; and

a sixth computer readable program code for requesting the second computer to execute the second program according to the updated master schedule and if the result meets the criterion.

12. The computer program product of claim 11, wherein the third computer readable program code further comprises a seventh computer readable program code for indicating in the updated master schedule that the execution of the first program depends on a condition;

and the fourth computer readable program code further comprises an eighth computer readable program code for requesting the first computer to execute the first program upon the occurrence of the condition.
