3 | Use a remote-hosted workflow |
||
4 | |||
5 | * When retrieving a workflow record for arvados-cwl-runner, API server notices workflow UUID is remote, and fetches it with salted token (instead of looking in local DB) |
||
6 | |||
7 | 4 | Tom Clegg | Mount remote-hosted collection (read-only) in a container - [[Federated collections]] |
8 | 1 | Tom Clegg | |
9 | 4 | Tom Clegg | * (controller) fetch remote-hosted container by UUID (similar to workflow case) |
10 | * (controller) rewrite locators in manifest to indicate remote cluster |
||
11 | * (keepstore) if locator indicates remote cluster and data does not exist locally (or local signature is not supplied), fetch from remote using salted token |
||
12 | 3 | Peter Amstutz | * When creating a container to satisfy a CR, API searches for collection PDH in cr.mounts across federated nodes, and fetches it with salted token (instead of looking in local DB) |
13 | 1 | Tom Clegg | |
14 | Run some portions of a CWL workflow on a remote cluster |
||
15 | |||
16 | * When submitting container requests, a-c-r follows workflow/commandline/input UUID hints to choose a cluster |
||
17 | * Either a-c-r handles the multi-cluster stuff itself, or it submits CRs with "submit to cluster X" flag, and the API server acts as a proxy |
