Detailed Description

Fortran interface functions.

The following are Fortran interface functions to QUDA that mirror the C-equivalents. This essentially just means making all calls by refere, using all the lower-case characters and adding a trailing underscore.

Definition in file quda_fortran.h.

Function Documentation

void clover_quda_	(	void *	h_out,
		void *	h_in,
		QudaInvertParam *	inv_param,
		QudaParity *	parity,
		int *	inverse
	)

Apply the clover operator or its inverse.

Parameters

h_out	Result spinor field
h_in	Input spinor field
param	Contains all metadata regarding host and device storage
parity	The source and destination parity of the field
inverse	Whether to apply the inverse of the clover term

Definition at line 1976 of file interface_quda.cpp.

void comm_set_gridsize_ ( int * grid )

Setter method for the comm grid size to all us to reuse BQCD's MPI topology. This is considered a temporary hack that will be fixed when an interface for setting the logical topology is created (issue 31 on github).

Definition at line 2006 of file interface_quda.cpp.

void dslash_quda_	(	void *	h_out,
		void *	h_in,
		QudaInvertParam *	inv_param,
		QudaParity *	parity
	)

Apply the Dslash operator (D_{eo} or D_{oe}).

Parameters

h_out	Result spinor field
h_in	Input spinor field
param	Contains all metadata regarding host and device storage
parity	The destination parity of the field

Definition at line 1974 of file interface_quda.cpp.

void end_quda_ ( void )

Finalize the library.

Definition at line 1968 of file interface_quda.cpp.

void free_clover_quda_ ( void )

Free QUDA's internal copy of the clover term and/or clover inverse.

Definition at line 1973 of file interface_quda.cpp.

void free_gauge_quda_ ( void )

Free QUDA's internal copy of the gauge field.

Definition at line 1970 of file interface_quda.cpp.

void init_quda_ ( int * device )

Initialize the library.

Parameters

device CUDA device number to use. In a multi-GPU build, this parameter may be either set explicitly on a per-process basis or set to -1 to enable a default allocation of devices to processes.

Definition at line 1967 of file interface_quda.cpp.

void invert_quda_	(	void *	h_x,
		void *	h_b,
		QudaInvertParam *	param
	)

Perform the solve, according to the parameters set in param. It is assumed that the gauge field has already been loaded via loadGaugeQuda().

Parameters

h_x	Solution spinor field
h_b	Source spinor field
param	Contains all metadata regarding host and device storage and solver parameters

Definition at line 1982 of file interface_quda.cpp.

void load_clover_quda_	(	void *	h_clover,
		void *	h_clovinv,
		QudaInvertParam *	inv_param
	)

Load the clover term and/or the clover inverse from the host. Either h_clover or h_clovinv may be set to NULL.

Parameters

h_clover	Base pointer to host clover field
h_cloverinv	Base pointer to host clover inverse field
inv_param	Contains all metadata regarding host and device storage

Definition at line 1971 of file interface_quda.cpp.

void load_gauge_quda_	(	void *	h_gauge,
		QudaGaugeParam *	param
	)

Load the gauge field from the host.

Parameters

h_gauge	Base pointer to host gauge field (regardless of dimensionality)
param	Contains all metadata regarding host and device storage

Definition at line 1969 of file interface_quda.cpp.

void mat_dag_mat_quda_	(	void *	h_out,
		void *	h_in,
		QudaInvertParam *	inv_param
	)

Apply M^{}M, possibly even/odd preconditioned.

Parameters

h_out	Result spinor field
h_in	Input spinor field
param	Contains all metadata regarding host and device storage

Definition at line 1980 of file interface_quda.cpp.

void mat_quda_	(	void *	h_out,
		void *	h_in,
		QudaInvertParam *	inv_param
	)

Apply the full Dslash matrix, possibly even/odd preconditioned.

Parameters

h_out	Result spinor field
h_in	Input spinor field
param	Contains all metadata regarding host and device storage

Definition at line 1978 of file interface_quda.cpp.

void new_quda_gauge_param_ ( QudaGaugeParam * param )

Initializes the QudaGaugeParam with default entries.

Parameters

The	QudaGaugeParam to be initialized

Definition at line 1984 of file interface_quda.cpp.

void new_quda_invert_param_ ( QudaInvertParam * param )

Initializes the QudaInvertParam with default entries.

Parameters

The	QudaInvertParam to be initialized

Definition at line 1987 of file interface_quda.cpp.
