ATLAS 3.8.2 (Default branch)
The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK. License: BSD License (original)Changes:
A performance bug where JITcp was always calledfrom ATL_gemmXX.c was fixed. A bug where complexGEMM sometimes read C when BETA=0 was fixed. TheFreeBSD architecture probe was improved. The LinuxCPU throttling probe was improved. Itanium 2detection was added as "McKinley" inarchinfo_linux. Cleanup was done for the 4x1 casefor 64-bit sgemm.Image

rdf::query::algebra

RDF::Query::Algebra(3pm)				User Contributed Perl Documentation				  RDF::Query::Algebra(3pm)

NAME

       RDF::Query::Algebra - Base class for Algebra expressions

VERSION

       This document describes RDF::Query::Algebra version 2.908.

METHODS

       "potentially_bound"
	   Returns a list of the variable names used in this algebra expression that will bind values during execution.

       "referenced_blanks"
	   Returns a list of the blank node names used in this algebra expression.

       "referenced_functions"
	   Returns a list of the Function URIs used in this algebra expression.

       "check_duplicate_blanks"
	   Returns true if blank nodes respect the SPARQL rule of no blank-label re-use across BGPs, otherwise throws a
	   RDF::Query::Error::QueryPatternError exception.

       "qualify_uris ( \%namespaces, $base_uri )"
	   Returns a new algebra pattern where all referenced Resource nodes representing QNames (ns:local) are qualified using the supplied
	   %namespaces.

       "bind_variables ( \%bound )"
	   Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.

       "is_solution_modifier"
	   Returns true if this node is a solution modifier.

       "subpatterns_of_type ( $type [, $block] )"
	   Returns a list of Algebra patterns matching $type (tested with "isa").  If $block is given, then matching stops descending a subtree if
	   the current node is of type $block, continuing matching on other subtrees.  This list includes the current algebra object if it matches
	   $type, and is generated in infix order.

       "from_sse ( $sse, \%context )"
	   Given an SSE serialization, returns the corresponding algebra expression.

FUNCTIONS

       "triple ( $subj, $pred, $obj )"
	   Returns a RDF::Query::Algebra::Triple object with the supplied node objects.

       "bgp ( @triples )"
	   Returns a RDF::Query::Algebra::BasicGraphPattern object with the supplied triples.

       "ggp ( @patterns )"
	   Returns a RDF::Query::Algebra::GroupGraphPattern object with the supplied algebra patterns.
