#                       Block Decomposition Specifier File
# This resource file specifies the block or block-cyclic memory distribution of memory in 
# terms of either fixed values or as a function of the total number of PETs. This functionality
# allows automatic scaling of the distribution space as a function of the machine resources.
#
# For all tests, both a source and destination decomposition is required. The specification 
# syntax consists of a collection of entries which specify a pair of distributions in terms 
# of either absolute distribution sizes, or relative sizes in terms of the total number of PETs.
# Entries:
# 1. descriptive string (enclosed by quote marks ')
# 2. tag indicating source specifiers  (enclosed by quote marks ')
# 3. rank of the source distribution (integer)
# 4. source specifiers for each dimension of the distribution  (operators enclosed by quote 
#    marks ', and values are real numbers)
# 5. tag indicating destination specifiers  (enclosed by quote marks ')
# 6. rank of the destination distribution (integer)
# 7. destination specifiers for each dimension of the distribution  (operators enclosed by 
#    quote marks ', and values are real numbers)
# 8. end tag  (enclosed by quote marks ')
#
# Specifier Syntax:
# - to set the distribution dimension to a set value: ==
# - to set the distribution dimension to a scalar multiple of the base dimension size: =*
# - to set the distribution dimension to a value plus a constant: =+
# Note: The product of all the base dimension sizes is equal to NPETS.
#
# Examples:
# A. 2x3 distribution redistributed to a 3x2 distribution
#    '(2,3)-->(3,2)'  'SRC' 2  'D1==' 2  'D2==' 3  'DST' 2  'D1==' 3  'D2==' 2  'END'  
# B. 1xNPETS distribution redistributed to a 2*sqrt(NPETS) X (1/2)*sqrt(NPETS) distribution 
#    '(1,n)-->(2*m,m/2)'  'SRC' 2  'D1==' 1  'D2=*' 1  'DST' 2  'D1=*' 2  'D2=*' 0.5  'END'  
# C. 1x2*NPETS distribution redistributed to a 2*sqrt(NPETS)-1 X (1/2)*sqrt(NPETS) distribution 
#    '(1,2*n)-->((2*m)-1,m/2)' 'SRC' 2 'D1==' 1 'D2=*' 2 'DST' 2 'D1=*' 2 'D1=+' -1 'D2=*' 0.5 'END'  
# D. 1xNPETS distribution redistributed to a 2*sqrt(NPETS) X (1/2)*sqrt(NPETS) distribution 
#    '(1,n)-->(2*(m-1),m/2)' 'SRC' 2 'D1==' 1 'D2=*' 1 'DST' 2 'D1=+'-1 'D1=*' 2 'D2=*' 0.5 'END'  
#  NOTE: the order of the operators is important
