Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that facilitate efficient allocation of computing resources of a cloud computing environment to job requests. Methods include receiving multiple job requests and sorting these job requests into one or more categories that include job requests with a same or similar set of job attributes. Methods include allocating a first number of computing resources of the compute farm to one or more job requests in each category. Methods include determining an allocation rate at which the first number of computing resources are allocated to the one or more job requests in each category. Methods include determining a remaining number of job requests in each category and allocating a second number of computing resources of the compute farm to the remaining number of job requests in each category based on the allocation rate.

Efficient allocation of cloud computing resources to job requests

A method and apparatus for performing fair-share preemption in a distributed computing environment is disclosed. The invention allows the suspension of jobs in a preempt-able set and the transfer of their respective resources, e.g. either hardware or software resources, to jobs in a preempting set. These activities are performed, all while assuring fairness among jobs scheduled to be executed and optimizing the use of available resources. In a preferred embodiment, the preempt-able and the preempting sets may include jobs characterized by, for example, job priorities, job ownership, or combinations thereof.

A method and apparatus for controlling the propagation of changes made to a data file in a system of interrelated data files is described. In one embodiment of the method of the invention, a run-time dependency management facility is provided on the computer system which is effective to generate under computer control a graph indicating relationships among the data files and software tools present on the system. A change is made to at least one of the data files and a determination is made as to whether that change is significant. If a significant change is made, then at least one propagation barrier is provided which is effective to prevent computer-implemented propagation of the change in said data file through at least one data file which is interdependent with the changed data file. In another embodiment, a computer readable medium containing program instructions for providing a run-time dependency management facility on a computer in which the run-time dependency facility is effective to generate under computer control a graph indicating relationships among the data files and the software tools residing on the system. The computer readable medium further includes program instructions for determining under computer control that the change to data in at least one of the data files is not a significant change. Finally the computer readable medium includes program instructions for generating at least one propagation barrier in response to the determination which is effective to prevent propagation of the changes in the data file through at least one data file which is interrelated with the changed data file. The above-described computer readable medium may also include program instructions for a clever tool which can determine whether changes made to the changed data file are significant.
