NUMA and hugepages

Use NUMA markers when a job needs a host with a specific topology.

numa-tests:
  tags:
    - saas-linux-large-amd64
    - numa:nodes:2
  variables:
    HW_NUMA_POLICY: "single-node"
  script:
    - ./run-numa-tests.sh

Use hugepage variables when the job must reserve hugepages:

hugepage-tests:
  tags:
    - saas-linux-large-amd64
  variables:
    HW_HUGEPAGE_BYTES: "1073741824"
    HW_NUMA_POLICY: "single-node"
  script:
    - ./run-hugepage-tests.sh
