29* Purpose
30* =======
31*
32* PZDOTU forms the dot product of two distributed vectors,
33*
34* dotu := sub( X )**T * sub( Y )
35*
36* where sub( X ) denotes X(IX,JX:JX+N-1) if INCX = M_X,
37* X(IX:IX+N-1,JX) if INCX = 1 and INCX <> M_X,
38*
39* sub( Y ) denotes Y(IY,JY:JY+N-1) if INCY = M_Y,
40* Y(IY:IY+N-1,JY) if INCY = 1 and INCY <> M_Y.
41*
42* Notes
43* =====
44*
45* Each global data object is described by an associated description
46* vector. This vector stores the information required to establish
47* the mapping between an object element and its corresponding process
48* and memory location.
49*
50* Let A be a generic term for any 2D block cyclicly distributed array.
51* Such a global array has an associated description vector descA.
52* In the following comments, the character _ should be read as
53* "of the global array".
54*
55* NOTATION STORED IN EXPLANATION
56* --------------- -------------- --------------------------------------
57* DT_A (global) descA[ DT_ ] The descriptor type. In this case,
58* DT_A = 1.
59* CTXT_A (global) descA[ CTXT_ ] The BLACS context handle, indicating
60* the BLACS process grid A is distribu-
61* ted over. The context itself is glo-
62* bal, but the handle (the integer
63* value) may vary.
64* M_A (global) descA[ M_ ] The number of rows in the global
65* array A.
66* N_A (global) descA[ N_ ] The number of columns in the global
67* array A.
68* MB_A (global) descA[ MB_ ] The blocking factor used to distribu-
69* te the rows of the array.
70* NB_A (global) descA[ NB_ ] The blocking factor used to distribu-
71* te the columns of the array.
72* RSRC_A (global) descA[ RSRC_ ] The process row over which the first
73* row of the array A is distributed.
74* CSRC_A (global) descA[ CSRC_ ] The process column over which the
75* first column of the array A is
76* distributed.
77* LLD_A (local) descA[ LLD_ ] The leading dimension of the local
78* array. LLD_A >= MAX(1,LOCr(M_A)).
79*
80* Let K be the number of rows or columns of a distributed matrix,
81* and assume that its process grid has dimension p x q.
82* LOCr( K ) denotes the number of elements of K that a process
83* would receive if K were distributed over the p processes of its
84* process column.
85* Similarly, LOCc( K ) denotes the number of elements of K that a
86* process would receive if K were distributed over the q processes of
87* its process row.
88* The values of LOCr() and LOCc() may be determined via a call to the
89* ScaLAPACK tool function, NUMROC:
90* LOCr( M ) = NUMROC( M, MB_A, MYROW, RSRC_A, NPROW ),
91* LOCc( N ) = NUMROC( N, NB_A, MYCOL, CSRC_A, NPCOL ).
92* An upper bound for these quantities may be computed by:
93* LOCr( M ) <= ceil( ceil(M/MB_A)/NPROW )*MB_A
94* LOCc( N ) <= ceil( ceil(N/NB_A)/NPCOL )*NB_A
95*
96* Because vectors may be seen as particular matrices, a distributed
97* vector is considered to be a distributed matrix.
98*
99* If INCX = M_X and INCY = M_Y, NB_X must be equal to NB_Y, and the
100* process column having the first entries of sub( Y ) must also contain
101* the first entries of sub( X ). Moreover, the quantity
102* MOD( JX-1, NB_X ) must be equal to MOD( JY-1, NB_Y ).
103*
104* If INCX = M_X, INCY = 1 and INCY <> M_Y, NB_X must be equal to MB_Y.
105* Moreover, the quantity MOD( JX-1, NB_X ) must be equal to
106* MOD( IY-1, MB_Y ).
107*
108* If INCX = 1, INCX <> M_X and INCY = M_Y, MB_X must be equal to NB_Y.
109* Moreover, the quantity MOD( IX-1, MB_X ) must be equal to
110* MOD( JY-1, NB_Y ).
111*
112* If INCX = 1, INCX <> M_X, INCY = 1 and INCY <> M_Y, MB_X must be
113* equal to MB_Y, and the process row having the first entries of
114* sub( Y ) must also contain the first entries of sub( X ). Moreover,
115* the quantity MOD( IX-1, MB_X ) must be equal to MOD( IY-1, MB_Y ).
