Constructor & Destructor Documentation

◆ cpuGaugeField()

quda::cpuGaugeField::cpuGaugeField ( const GaugeFieldParam & param )

Constructor for cpuGaugeField from a GaugeFieldParam.

Parameters

[in,out] param Parameter struct - note that in the case that we are wrapping host-side extended fields, this param is modified for subsequent creation of fields that are not extended.
