		row_indices &	rows_in,
		col_indices &	cols_in
	)

Constructor of the class.

Parameters

A_in	The object representing matrix A.

Member Function Documentation

print()

void logging::print ( const std::stringstream &  sstream, int  verbose_level = 1  ) const

inherited

Call to print output messages in the function of the verbosity level.

Parameters

sstream	The stringstream input to store the output messages.
verbose_level	Integer input. High level means write more to the standart output, 0 means write nothing. The default value is set to 1.

Definition at line 55 of file logging.cpp.

set_debugfile()

void logging::set_debugfile ( std::string  debugfile )

inherited

Call to set the debugfile name.

Parameters

debugfile

String variable. Set the debugfile name.

Definition at line 95 of file logging.cpp.

Here is the caller graph for this function:

set_verbose()

void logging::set_verbose ( int  verbose_in )

inherited

Call to set the verbose attribute.

Parameters

verbose_in

Integer variable. Set the number to specify the verbosity level for output messages.

Definition at line 85 of file logging.cpp.

Here is the caller graph for this function:

zgemm_chunk()

void zgemm_Task_serial::zgemm_chunk

(

)

Call to calculate the product of matrix chunks defined by attributes rows, cols.

The result is stored in the corresponding chunk of matrix C.
