Dev Engineer Review

• Updated oci-jhb* UCX settings to match oci-aga*.
• The rule enables CUDA, shared memory, and TCP transports and prefers IPv4.
• Added aws-dfw and oci-jhb to the documented cluster names.
• Verify that OCI-JHB nodes support the selected transports.

QA Engineer Review

• Modified tests/unittest/scripts/test_cluster_env.py.
• Added coverage for oci-jhb-slurm-1 and its expected UCX environment export.
• The test does not explicitly verify every configured transport or IPv4 preference.
• No integration test-list changes apply.
• Coverage verdict: needs follow-up.

Per-File QA Perspective

• jenkins/scripts/perf/cluster_env.py: Verify the expected UCX settings and confirm that the wildcard matches only intended cluster names.
• tests/unittest/scripts/test_cluster_env.py: Validates the OCI-JHB UCX export. This unit test does not require an integration test-list entry.

Walkthrough

The cluster configuration adds aws-dfw and oci-jhb to the documented names. It adds an oci-jhb* UCX rule with CUDA, shared-memory, TCP, and IPv4 settings. A unit test verifies the configuration for oci-jhb-slurm-1.

Changes

OCI Johannesburg cluster support

Layer / File(s)	Summary
Cluster naming and UCX configuration jenkins/scripts/perf/cluster_env.py, tests/unittest/scripts/test_cluster_env.py	The documented cluster names include oci-jhb. The oci-aga* and oci-jhb* rules force cuda_ipc,cuda_copy,sm,self,tcp and set UCX_TCP_AF_PRIO=inet. Tests verify the oci-jhb-slurm-1 environment export.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to ba4a8

OCI Johannesburg clusters now receive the same CUDA, shared-memory, TCP, and IPv4 UCX settings as OCI AGA. The configuration behavior is covered by a targeted unit test, with no outstanding merge-readiness risk identified.
