Fixed the issue in which GPUDirect-TCPX for a3-highgpu-8g machine types was incompatible with the Linux kernel version that was used by Container-Optimized OS in GKE version 1.34 and later. To prevent errors, GKE blocked creating or upgrading node pools that used the a3-highgpu-8g machine type to version 1.34 or later. For more information about this issue, see GKE known issues.

You can now create or upgrade node pools that use the a3-highgpu-8g machine type to any of the following GKE versions. Automatic upgrades of these node pools from version 1.33 to version 1.34 or later are no longer blocked.

• For minor version 1.34, use patch version 1.34.5-gke.1153000 or later.
• For minor version 1.35, use patch version 1.35.2-gke.1485000 or later.
• For minor version 1.36 and later, use any available patch version.

In GKE version 1.34 and later, you must use version 3.1.9 or later of the GPUDirect-TCPX installer and version 2.0.12 or later of the GPUDirect-TCPX sidecar. If you previously installed these components, verify that the container images use these versions or later. To avoid degraded performance or workload failures, update your installer and sidecar image versions before the a3-highgpu-8g node pools are manually or automatically upgraded to version 1.34 or later. These container image versions correspond to the upstream definitions maintained in the gpudirect-tcpx GitHub repository.
