Abstract

The technology disclosed herein enables migrating a software build job from a first computing node to a second computing node. An example method may comprise detecting, by a processor, a first software build job executing on a first computing node; detecting a second software build job in a waiting state; determining that the first computing node is capable of executing the second software build job; responsive to determining that a second computing node is capable of executing the first software build job, migrating the first software build job to the second node; and executing the second software build job on the first node.

First claim

What is claimed is:

1. A method comprising:
detecting, by a processor, a first software build job executing on a first computing node;
detecting a second software build job in a waiting state;
determining that the first computing node is capable of executing the second software build job;
responsive to determining that a second computing node is capable of executing the first software build job and that the second computing node is incapable of executing the second software build job due to at least one computing resource of the second computing node having a first value of a chosen performance characteristic less than a second value of the chosen performance characteristic of a corresponding computing resource of the first computing node, migrating the first software build job to the second computing node by:
suspending execution of the first software build job; and
transferring, to the second computing node, compiled code and data logs associated with an executed portion of the first software build job and an indication of where to resume execution of the first software build job on the second computing node;

initiating execution of the first software build job on the second computing node; and
initiating execution of the second software build job on the first computing node.

2. The method of claim 1 , further comprising:
detecting a third computing node that is capable of executing at least a part of the second software build job;
executing a first stage of the second software build job on the first computing node; and
executing a second stage of the second software build job on the third computing node.

3. The method of claim 2 , further comprising:
generating a first data log associated with the first stage of the second software build job executed by the first computing node;
generating a second data log associated with the second stage of the second software build job from the second computing node; and
aggregating the first data log and the second data log into a third data log.

4. The method of claim 1 , wherein a first set of resources associated with the second computing node comprises at least one resource that has a performance characteristic less than a comparable resource of a second set of resources associated with the first computing node.

5. The method of claim 1 , further comprising:
responsive to migrating the first software build job to the second computing node, sending an indication to a client device that the first computing node is free.

6. The method of claim 1 , further comprising:
performing periodic scans to determine whether an executing software build job executing on an initial computing node may be migrated to another computing node that has a performance characteristic less than a comparable resource of the initial computing node.

7. A system comprising:
a memory;
a processing device operatively coupled to the memory, the processing device configured to:
detect a first software build job executing on a first computing node;
detect a second software build job in a waiting state;
determine that the first computing node is capable of executing the second software build job;
responsive to determining that a second node is capable of executing the first software build job and that the second node is incapable of executing the second software build job due to at least one computing resource of the second computing node having a first value of a chosen performance characteristic less than a second value of the chosen performance characteristic of a corresponding computing resource of the first computing node, migrate the first software build job to the second computing node by:
suspending execution of the first software build job; and
transferring, to the second computing node, compiled code and data logs associated with an executed portion of the first software build job and an indication of where to resume execution of the first software build job on the second computing node;

initiating execution of the first software build job on the second computing node; and
initiating execution of the second software build job on the first computing node.

8. The system of claim 7 , wherein the processing device is further configured to:
detect a third computing node that is capable of executing at least a part of the second software build job;
execute a first stage of the second software build job on the first computing node; and
execute a second stage of the second software build job on the third computing node.

9. The system of claim 8 , wherein the processing device is further configured to:
generate a first data log associated with the first stage of the second software build job executed by the first computing node;
generate a second data log associated with the second stage of the second software build job from the second computing node; and
aggregate the first data log and the second data log into a third data log.

10. The system of claim 7 , wherein a first set of resources associated with the second computing node comprises at least one resource that has a performance characteristic less than a comparable resource of a second set of resources associated with the first computing node.

11. The system of claim 7 , wherein the processing device is further configured to:
responsive to migrating the first software build job to the second computing node, send an indication to a client device that the first computing node is free.

12. The system of claim 7 , wherein the processing device is further configured to:
perform periodic scans to determine whether an executing software build job executing on an initial computing node may be migrated to another computing node that has a performance characteristic less than a comparable resource of the initial computing node.

13. A non-transitory machine-readable storage medium storing executable instructions that, when executed by a processing device, cause the processing device to:
detect a first software build job executing on a first computing node;
detect a second software build job in a waiting state;
determine that the first computing node is capable of executing the second software build job;
responsive to determining that a second computing node is capable of executing the first software build job and that the second computing node is incapable of executing the second software build job due to at least one computing resource of the second computing node having a first value of a chosen performance characteristic less than a second value of the chosen performance characteristic of a corresponding computing resource of the first computing node, migrate the first software build job to the second computing node by:
suspending execution of the first software build job; and
transferring, to the second computing node, compiled code and data logs associated with an executed portion of the first software build job and an indication of where to resume execution of the first software build job on the second computing node;

initiating execution of the first software build job on the second computing node; and
initiating execution of the second software build job on the first computing node.

14. The non-transitory machine-readable storage medium of claim 13 , further comprising executable instructions that, when executed by the processing device, cause the processing device to:
detect a third computing node that is capable of executing at least a part of the second software build job;
execute a first stage of the second software build job on the first computing node; and
execute a second stage of the second softwa
