Autonomous management of system throughput

1. A computer program product comprising computer executable instructions stored on computer storage media, the instructions for managing a workload comprising work units in a computing system, the product comprising instructions for:

collecting resource and state data for a plurality of service class periods;

calculating a long term execution velocity;

if sufficient data exists, then determining a goal velocity using the data, otherwise, selecting a default value for the goal velocity;

associating the goal velocity with the respective service class period;

repeating the calculating, determining, selecting and associating for each service class period in the plurality service class periods; and

adjusting resource access to each of the service class periods according to the associated goal velocities;

wherein determining the goal velocity comprises solving a relationship comprising:

GoalVelocity= MIN(MaxPosVelocity; Adjusted(TargetPI*LTVelocity))

where:

MIN is a function that returns a minimum value for an argument list wherein the performance index comprises an index that is at least one of; very fast, fast, moderate, slow and very slow;

TargetPI represents a performance index;

LTVelocity represents the long term execution velocity for the service class;

MaxPosVelocity represents a maximum possible execution velocity for all work at the importance level; and

Adjusted( ) is a function that rounds the target goal velocity.

2. The computer program product as in claim 1 , further comprising instructions for receiving an externally set velocity objective for the long term execution velocity.

3. The computer program product as in claim 1 , further comprising instructions for determining a performance index.

4. The computer program product as in claim 3 , further comprising instructions for determining the goal velocity according to the performance index.
