12*
13* -- PBLAS testing driver (version 2.0.2) --

17* Purpose
18* =======
19*
20* PCBLA2TST is the main testing program for the PBLAS Level 2 routines.
21*
22* The program must be driven by a short data file. An annotated exam-
23* ple of a data file can be obtained by deleting the first 3 characters
24* from the following 61 lines:
25* 'Level 2 PBLAS, Testing input file'
26* 'Intel iPSC/860 hypercube, gamma model.'
27* 'PCBLAS2TST.SUMM' output file name (if any)
28* 6 device out
29* F logical flag, T to stop on failures
30* F logical flag, T to test error exits
31* 0 verbosity, 0 for pass/fail, 1-3 for matrix dump on errors
32* 10 the leading dimension gap

87* Internal Parameters
88* ===================
89*
90* TOTMEM INTEGER
91* TOTMEM is a machine-specific parameter indicating the maxi-
92* mum amount of available memory per process in bytes. The
93* user should customize TOTMEM to his platform. Remember to
94* leave room in memory for the operating system, the BLACS
95* buffer, etc. For example, on a system with 8 MB of memory
96* per process (e.g., one processor on an Intel iPSC/860), the
97* parameters we use are TOTMEM=6200000 (leaving 1.8 MB for OS,
98* code, BLACS buffer, etc). However, for PVM, we usually set
99* TOTMEM = 2000000. Some experimenting with the maximum value
100* of TOTMEM may be required. By default, TOTMEM is 2000000.
101*
102* REALSZ INTEGER
103* CPLXSZ INTEGER
104* REALSZ and CPLXSZ indicate the length in bytes on the given
105* platform for a single precision real and a single precision
106* complex. By default, REALSZ is set to four and CPLXSZ is set
107* to eight.
108*
109* MEM COMPLEX array
110* MEM is an array of dimension TOTMEM / CPLXSZ.
111* All arrays used by SCALAPACK routines are allocated from this
112* array MEM and referenced by pointers. The integer IPA, for
113* example, is a pointer to the starting element of MEM for the
114* matrix A.

2270* On entry, ICTXT specifies the BLACS context handle, indica-
2271* ting the global context of the operation. The context itself
2272* is global, but the value of ICTXT is local.

2275* On entry, NOUT specifies the unit number for the output file.
2276* When NOUT is 6, output to screen, when NOUT is 0, output to
2277* stderr. NOUT is only defined for process 0.

2296* On entry, M specifies the dimension of the submatrix ope-
2297* rands.
2298*
2299* N (global input) INTEGER
2300* On entry, N specifies the dimension of the submatrix ope-
2301* rands.
2302*
2303* ALPHA (global input) COMPLEX
2304* On entry, ALPHA specifies the scalar alpha.
2305*
2306* IA (global input) INTEGER

2308* the beginning of the submatrix sub( A ).
2309*
2310* JA (global input) INTEGER
2311* On entry, JA specifies A's global column index, which points
2312* to the beginning of the submatrix sub( A ).
2313*
2314* DESCA (global and local input) INTEGER array
2315* On entry, DESCA is an integer array of dimension DLEN_. This
2316* is the array descriptor for the matrix A.
2317*
2318* IX (global input) INTEGER
2319* On entry, IX specifies X's global row index, which points to
2320* the beginning of the submatrix sub( X ).
2321*
2322* JX (global input) INTEGER
2323* On entry, JX specifies X's global column index, which points
2324* to the beginning of the submatrix sub( X ).
2325*
2326* DESCX (global and local input) INTEGER array
2327* On entry, DESCX is an integer array of dimension DLEN_. This
2328* is the array descriptor for the matrix X.
2329*
2330* INCX (global input) INTEGER
2331* On entry, INCX specifies the global increment for the
2332* elements of X. Only two values of INCX are supported in
2333* this version, namely 1 and M_X. INCX must not be zero.
2334*

2349*
2350* INCY (global input) INTEGER
2351* On entry, INCY specifies the global increment for the
2352* elements of Y. Only two values of INCY are supported in
2353* this version, namely 1 and M_Y. INCY must not be zero.
2354*
2355* INFO (global input/global output) INTEGER
2356* When INFO = 0 on entry, the values of the arguments which are
2357* INPUT only arguments to a PBLAS routine are copied into sta-
2358* tic variables and INFO is unchanged on exit. Otherwise, the
2359* values of the arguments are compared against the saved co-
2360* pies. In case no error has been found INFO is zero on return,
2361* otherwise it is non zero.

2593* Notes
2594* =====
2595*
2596* A description vector is associated with each 2D block-cyclicly dis-
2597* tributed matrix. This vector stores the information required to
2598* establish the mapping between a matrix entry and its corresponding
2599* process and memory location.
2600*
2601* In the following comments, the character _ should be read as
2602* "of the distributed matrix". Let A be a generic term for any 2D
2603* block cyclicly distributed matrix. Its description vector is DESCA:
2604*
2605* NOTATION STORED IN EXPLANATION
2606* ---------------- --------------- ------------------------------------
2607* DTYPE_A (global) DESCA( DTYPE_ ) The descriptor type.
2608* CTXT_A (global) DESCA( CTXT_ ) The BLACS context handle, indicating
2609* the NPROW x NPCOL BLACS process grid
2610* A is distributed over. The context
2611* itself is global, but the handle
2612* (the integer value) may vary.
2613* M_A (global) DESCA( M_ ) The number of rows in the distribu-
2614* ted matrix A, M_A >= 0.
2615* N_A (global) DESCA( N_ ) The number of columns in the distri-
2616* buted matrix A, N_A >= 0.
2617* IMB_A (global) DESCA( IMB_ ) The number of rows of the upper left
2618* block of the matrix A, IMB_A > 0.
2619* INB_A (global) DESCA( INB_ ) The number of columns of the upper
2620* left block of the matrix A,
2621* INB_A > 0.
2622* MB_A (global) DESCA( MB_ ) The blocking factor used to distri-
2623* bute the last M_A-IMB_A rows of A,
2624* MB_A > 0.
2625* NB_A (global) DESCA( NB_ ) The blocking factor used to distri-
2626* bute the last N_A-INB_A columns of
2627* A, NB_A > 0.
2628* RSRC_A (global) DESCA( RSRC_ ) The process row over which the first
2629* row of the matrix A is distributed,
2630* NPROW > RSRC_A >= 0.
2631* CSRC_A (global) DESCA( CSRC_ ) The process column over which the
2632* first column of A is distributed.
2633* NPCOL > CSRC_A >= 0.
2634* LLD_A (local) DESCA( LLD_ ) The leading dimension of the local
2635* array storing the local blocks of
2636* the distributed matrix A,
2637* IF( Lc( 1, N_A ) > 0 )
2638* LLD_A >= MAX( 1, Lr( 1, M_A ) )
2639* ELSE
2640* LLD_A >= 1.
2641*
2642* Let K be the number of rows of a matrix A starting at the global in-
2643* dex IA,i.e, A( IA:IA+K-1, : ). Lr( IA, K ) denotes the number of rows
2644* that the process of row coordinate MYROW ( 0 <= MYROW < NPROW ) would
2645* receive if these K rows were distributed over NPROW processes. If K
2646* is the number of columns of a matrix A starting at the global index
2647* JA, i.e, A( :, JA:JA+K-1, : ), Lc( JA, K ) denotes the number of co-
2648* lumns that the process MYCOL ( 0 <= MYCOL < NPCOL ) would receive if
2649* these K columns were distributed over NPCOL processes.
2650*
2651* The values of Lr() and Lc() may be determined via a call to the func-
2652* tion PB_NUMROC:
2653* Lr( IA, K ) = PB_NUMROC( K, IA, IMB_A, MB_A, MYROW, RSRC_A, NPROW )
2654* Lc( JA, K ) = PB_NUMROC( K, JA, INB_A, NB_A, MYCOL, CSRC_A, NPCOL )
