experimentalChangeAllocator() [1/3]

void Arcane::VariableUtils::experimentalChangeAllocator	(	::Arcane::Materials::IMeshMaterialVariable *	var,
		eMemoryRessource	mem )

Definition at line 113 of file VariableUtils.cc.

experimentalChangeAllocator() [2/3]

void Arcane::VariableUtils::experimentalChangeAllocator	(	IVariable *	var,
		eMemoryRessource	mem )

Definition at line 127 of file VariableUtils.cc.

experimentalChangeAllocator() [3/3]

void Arcane::VariableUtils::experimentalChangeAllocator	(	VariableRef &	var,
		eMemoryRessource	mem )

Definition at line 137 of file VariableUtils.cc.

markVariableAsMostlyReadOnly() [1/3]

void Arcane::VariableUtils::markVariableAsMostlyReadOnly

(

::Arcane::Materials::MeshMaterialVariableRef &

var

)

Indicates that the variable is mostly read-only. void markVariableAsMostlyReadOnly(IVariableRef* var);.

Definition at line 102 of file VariableUtils.cc.

Here is the call graph for this function:

markVariableAsMostlyReadOnly() [2/3]

void Arcane::VariableUtils::markVariableAsMostlyReadOnly

(

IVariable *

var

)

Indicates that the variable is mostly read-only.

This is used only with accelerators and prevents memory transfers between the accelerator and the CPU.

Here is the call graph for this function:

markVariableAsMostlyReadOnly() [3/3]

void Arcane::VariableUtils::markVariableAsMostlyReadOnly

(

VariableRef &

var

)

Indicates that the variable is mostly read-only. void markVariableAsMostlyReadOnly(IVariableRef* var);.

Definition at line 93 of file VariableUtils.cc.

References Arcane::VariableRef::variable().

Here is the call graph for this function:

prefetchVariableAsync() [1/2]

void Arcane::VariableUtils::prefetchVariableAsync	(	IVariable *	var,
		const RunQueue *	queue_or_null )

Prefetches the memory associated with the variable var.

Prefetches the memory associated with the variable onto the accelerator specified by queue_or_null if it is not already there.

var must be a numerical type variable. If queue_or_null is null, no operation is performed. The operation is asynchronous.

Here is the call graph for this function:

prefetchVariableAsync() [2/2]

void Arcane::VariableUtils::prefetchVariableAsync	(	VariableRef &	var,
		const RunQueue *	queue_or_null )

Prefetches the memory associated with the variable var.
