Member Function Documentation

void Host::setState ( e_surf_resource_state_t state )

virtual

Set the state of the current Resource.

Parameters

state The new state of the current Resource

Reimplemented from Resource.

Reimplemented in VM.

xbt_dict_t Host::getProperties ( )

virtual

Get the properties of the current Host.

Returns: The properties of the current Host

Reimplemented from Resource.

virtual Action* Host::execute ( double flops_amount )

pure virtual

Execute some quantity of computation.

Parameters

flops_amount The value of the processing amount (in flop) needed to process

Returns: The CpuAction corresponding to the processing

See also: Cpu

virtual Action* Host::sleep ( double duration )

pure virtual

Make a process sleep for duration seconds.

Parameters

duration The number of seconds to sleep

Returns: The CpuAction corresponding to the sleeping

See also: Cpu

virtual

Open a file.

Parameters

fullpath The full path to the file

Returns: The StorageAction corresponding to the opening

[long description]

Parameters

fd	[description]

Returns: [description]

sg_size_t Host::getSize ( surf_file_t fd )

virtual

Get the size in bytes of the file.

Parameters

fd	The file descriptor to read

Returns: The size in bytes of the file

xbt_dynar_t Host::getInfo ( surf_file_t fd )

virtual

Get the informations of a file descriptor.

The returned xbt_dynar_t contains:

the size of the file,
the mount point,
the storage name,
the storage typeId,
the storage content type

Parameters

fd	The file descriptor

Returns: An xbt_dynar_t with the file informations

sg_size_t Host::fileTell ( surf_file_t fd )

virtual

Get the current position of the file descriptor.

Parameters

int Host::fileSeek	(	surf_file_t	fd,
		sg_offset_t	offset,
		int	origin
	)

virtual

Set the position indicator associated with the file descriptor to a new position.

[long description]

Parameters

fd	The file descriptor
offset	The offset from the origin
origin	Position used as a reference for the offset SEEK_SET: beginning of the file SEEK_CUR: current position indicator SEEK_END: end of the file

Returns: MSG_OK if successful, otherwise MSG_TASK_CANCELED

int Host::fileMove	(	surf_file_t	fd,
		const char *	fullpath
	)

virtual

Move a file to another location on the same mount point.

[long description]

Parameters

fd	The file descriptor
fullpath	The new full path

Returns: MSG_OK if successful, MSG_TASK_CANCELED and a warning if the new full path is not on the same mount point

void Host::getParams ( vm_params_t params )

Retrieve a copy of the parameters of that VM/PM.

The ramsize and overcommit fields are used on the PM too
