# A Heat environment that can be used to deploy a real-time compute node

# Deploying a real-time compute node requires enabling hugepages for the
|
|
# overcloud nodes, which is done by default for the ComputeRealTime role.
|
|
# However, the CPU pinnings (IsolCpusList and NovaVcpuPinSet) need to be set in
|
|
# an environment file like this, according to the hardware used for the
|
|
# real-time compute nodes.
|
|
# Also the hugepages parameters in KernelArgs should be set accordingly
|
|
# the memory of the real-time compute nodes.
|
|
# It's also possible to overwrite the default values for other parameters like
|
|
# TunedProfileName and ComputeRealTimeImage here.
