Distributed scheduling in a virtual machine environment
First Claim
1. A method comprising:
- storing by a first scheduler into a memory of a first virtual machine running on a server computer system, a first block of jobs to be executed by the first virtual machine, the first block of jobs being included in a job table stored in a database and having a first block size, the database associated with the server computer system;
storing by a second scheduler into a memory of a second virtual machine running on the server computer system, a second block of jobs to be executed by the by the second virtual machine, the second block of jobs being included in the job table and having a second block size, the second block size being equal to the first block size and including jobs that are not in included in the first block of jobs;
scheduling by the first scheduler from the memory of the first virtual machine, one or more jobs in the first block of jobs for execution by the first virtual machine; and
scheduling by the second scheduler from the memory of the second virtual machine, one or more jobs in the second block of jobs for execution by the second virtual machine.

Abstract
A first scheduler stores into a memory of a first virtual machine, a first block of jobs to be executed by the first virtual machine, the first block of jobs included in a table stored in a database associated with a server computer system. A second scheduler stores into a memory of a second virtual machine, a second block of jobs to be executed by the second virtual machine. The second block of jobs being included in the table and having a second block size equal to the first block size and including jobs not in the first block. From the first virtual machine memory, the first scheduler schedules one or more jobs in the first block for execution by the first virtual machine. From the second virtual machine memory, the second scheduler schedules one or more jobs in the second block for execution by the second virtual machine.

10. An apparatus comprising:
-
one or more processors; and a non-transitory computer readable medium storing a plurality of instructions, which when executed, cause the one or more processors to; store by a first scheduler into a memory of a first virtual machine running on a server computer system, a first block of jobs to be executed by the first virtual machine, the first block of jobs being included in a job table stored in a database and having a first block size, the database associated with the server computer system; store by a second scheduler into a memory of a second virtual machine running on the server computer system, a second block of jobs to be executed by the second virtual machine, the second block of jobs being included in the job table and having a second block size, the second block size being equal to the first block size and including jobs that are not in included in the first block of jobs; schedule by the first scheduler from the memory of the first virtual machine, one or more jobs in the first block of jobs for execution by the first virtual machine; and schedule by the second scheduler from the memory of the second virtual machine, one or more jobs in the second block of jobs for execution by the second virtual machine. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions to:
-
store by a first scheduler into a memory of a first virtual machine running on a server computer system, a first block of jobs to be executed by the first virtual machine, the first block of jobs being included in a job table stored in a database and having a first block size, the database associated with the server computer system; store by a second scheduler into a memory of a second virtual machine running on the server computer system, a second block of jobs to be executed by the second virtual machine, the second block of jobs being included in the job table and having a second block size, the second block size being equal to the first block size and including jobs that are not in included in the first block of jobs; schedule by the first scheduler from the memory of the first virtual machine, one or more jobs in the first block of jobs for execution by the first virtual machine; and schedule by the second scheduler from the memory of the second virtual machine, one or more jobs in the second block of jobs for execution by the second virtual machine. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
