11 ## Host configuration Parameters
12 #TunedProfileName: "cpu-partitioning"
13 #IsolCpusList: "" # Logical CPUs list to be isolated from the host process (applied via cpu-partitioning tuned).
14 # It is mandatory to provide isolated cpus for tuned to achive optimal performance.
15 # Example: "3-8,12-15,18"
16 #KernelArgs: "" # Space separated kernel args to configure hugepage and IOMMU.
17 # Deploying DPDK requires enabling hugepages for the overcloud compute nodes.
18 # It also requires enabling IOMMU when using the VFIO (vfio-pci) OvsDpdkDriverType.
19 # This should be done by configuring parameters via host-config-and-reboot.yaml environment file.
21 ## Attempting to deploy DPDK without appropriate values for the below parameters may lead to unstable deployments
22 ## due to CPU contention of DPDK PMD threads.
23 ## It is highly recommended to to enable isolcpus (via KernelArgs) on compute overcloud nodes and set the following parameters:
24 #OvsDpdkSocketMemory: "" # Sets the amount of hugepage memory to assign per NUMA node.
25 # It is recommended to use the socket closest to the PCIe slot used for the
26 # desired DPDK NIC. Format should be comma separated per socket string such as:
27 # "<socket 0 mem MB>,<socket 1 mem MB>", for example: "1024,0".
28 #OvsDpdkDriverType: "vfio-pci" # Ensure the Overcloud NIC to be used for DPDK supports this UIO/PMD driver.
29 #OvsPmdCoreList: "" # List or range of CPU cores for PMD threads to be pinned to. Note, NIC
30 # location to cores on socket, number of hyper-threaded logical cores, and
31 # desired number of PMD threads can all play a role in configuring this setting.
32 # These cores should be on the same socket where OvsDpdkSocketMemory is assigned.
33 # If using hyperthreading then specify both logical cores that would equal the
34 # physical core. Also, specifying more than one core will trigger multiple PMD
35 # threads to be spawned, which may improve dataplane performance.
36 #NovaVcpuPinSet: "" # Cores to pin Nova instances to. For maximum performance, select cores
37 # on the same NUMA node(s) selected for previous settings.
