Member Function Documentation

isRootInstance()

bool HiCR::backend::hwloc::Instance::isRootInstance ( ) const

inlineoverridevirtual

This function reports whether the caller is the root instance

The root instance represents a single instance in the entire deployment with the following characteristics:

• It is unique. Only a single instance shall be root in the entire deployment, even if new ones are created.
• It belongs among the first set of instances created during launch time
• It has no parent instance

The purpose of the root instance is to provide the minimal tiebreak mechanism that helps in role/task distribution.

Note

Each backend decides how to designate the root instance. Hence, this is a pure virtual function.

Returns

True, if the current instance is root; false, otherwise.

Implements HiCR::Instance.
