The most noteworthy changes since the previous release are described here.
New features
The following features are new in this release:
- Scaling improvements for larger systems to the following services:
- New hardware supported in this release:
- Compute nodes
- Milan-Based Grizzly Peak with A100 40 GB GPU
- Milan-Based Windom Liquid Cooled System
- Rome-Based HPE Apollo 6500 XL675d Gen10+ with A100 40 GB GPU
- Rome-Based HPE Apollo 6500 XL645d Gen10+ with A100 40 GB GPU
- User Access Nodes (UANs)
- Milan-Based HPE DL 385(v2) Gen10+
- Rome-Based HPE DL 385(v1) Gen10
- Node consoles are now managed by
cray-console-node which is based on ConMan
- HSM now has a v2 REST API
- NCN user password and SSH key management is available for both root and
non-root users via NCN personalization. See Configure Non-Compute Nodes with CFS.
Deprecated features
The following features are no longer supported and are planned to be removed in a future release:
- HSM v1 REST API has been deprecated as of CSM version 0.9.3. The v1 HSM APIs will be removed in the CSM version 1.3 release.
- Many CAPMC v1 REST API and CLI features were deprecated as part of CSM version 1.0; Full removal of the deprecated CAPMC features will happen in CSM version 1.3. Further
development of CAPMC service or CLI has stopped. CAPMC has entered end-of-life but will still be generally available. CAPMC is going to be replaced with the Power Control
Service (PCS) in a future release. The current API/CLI portfolio for CAPMC is being pruned to better align with the future direction of PCS. More information about PCS and
the CAPMC transition will be released as part of subsequent CSM releases.
- HMNFD v1 REST API has been deprecated as of CSM version 1.2. The v1 HMNFD APIs will be removed in the CSM version 1.5 release.
- The Boot Orchestration Service (BOS) API is changing in the CSM V1.2.0 release:
- The
--template-body option for the Cray CLI bos command is deprecated.
- Prior to CSM V1.2.0, performing a successful
GET on the session status for a boot set (i.e. /v1/session/{session_id}/status/{boot_set_name}) incorrectly returned
a status code of 201. It now correctly returns a status code of 200.
- The Compute Rolling Upgrade Service (CRUS) is deprecated in CSM 1.2.0 and will be removed in CSM 1.5.0. Enhanced BOS functionality will replace CRUS. This includes the ability
to stage changes to nodes that can be acted upon later when the node reboots. It also includes the ability to reboot nodes without specifying any boot artifacts. This latter
ability relies on the artifacts already having been staged.
- SLS support for downloading and uploading credentials in the
dumpstate and loadstate REST APIs.
Removed features
The following features have been completely removed:
cray-conman pod. This has been replaced by cray-console-node.- CFS v1 API and CLI. The v2 API and CLI have been the default since CSM 0.9 (Shasta 1.4).
