11 PROGRAM psbla2tst
12*
13* -- PBLAS testing driver (version 2.0.2) --
14* Univ. of Tennessee, Univ. of California Berkeley, Univ. of Colorado Denver

17* Purpose
18* =======
19*
20* PSBLA2TST 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 60 lines:
25* 'Level 2 PBLAS, Testing input file'
26* 'Intel iPSC/860 hypercube, gamma model.'
27* 'PSBLAS2TST.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
33* 16.0 threshold value of test ratio
34* 10 value of the logical computational blocksize NB

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

2218* only arguments to PBLAS routines). Otherwise, it verifies the values
2219* of these arguments against the saved copies.

2222* =========
2223*
2224* ICTXT (local input) INTEGER
2225* On entry, ICTXT specifies the BLACS context handle, indica-
2226* ting the global context of the operation. The context itself
2227* is global, but the value of ICTXT is local.

2265* JA (global input) INTEGER
2266* On entry, JA specifies A's global column index, which points
2267* to the beginning of the submatrix sub( A ).
2268*
2269* DESCA (global and local input) INTEGER array
2270* On entry, DESCA is an integer array of dimension DLEN_. This
2271* is the array descriptor for the matrix A.
2272*
2273* IX (global input) INTEGER
2274* On entry, IX specifies X's global row index, which points to
2275* the beginning of the submatrix sub( X ).
2276*
2277* JX (global input) INTEGER
2278* On entry, JX specifies X's global column index, which points
2279* to the beginning of the submatrix sub( X ).
2280*
2281* DESCX (global and local input) INTEGER array
2282* On entry, DESCX is an integer array of dimension DLEN_. This
2283* is the array descriptor for the matrix X.
2284*
2285* INCX (global input) INTEGER
2286* On entry, INCX specifies the global increment for the
2287* elements of X. Only two values of INCX are supported in
2288* this version, namely 1 and M_X. INCX must not be zero.

2303* is the array descriptor for the matrix Y.
2304*
2305* INCY (global input) INTEGER
2306* On entry, INCY specifies the global increment for the
2307* elements of Y. Only two values of INCY are supported in
2308* this version, namely 1 and M_Y. INCY must not be zero.
2309*
2310* INFO (global input/global output) INTEGER
2311* When INFO = 0 on entry, the values of the arguments which are
2312* INPUT only arguments to a PBLAS routine are copied into sta-
2313* tic variables and INFO is unchanged on exit. Otherwise, the
2314* values of the arguments are compared against the saved co-
2315* pies. In case no error has been found INFO is zero on return,
2316* otherwise it is non zero.

2546* Notes
2547* =====
2548*
2549* A description vector is associated with each 2D block-cyclicly dis-
2550* tributed matrix. This vector stores the information required to
2551* establish the mapping between a matrix entry and its corresponding
2552* process and memory location.
2553*
2554* In the following comments, the character _ should be read as
2555* "of the distributed matrix". Let A be a generic term for any 2D
2556* block cyclicly distributed matrix. Its description vector is DESCA:
2557*
2558* NOTATION STORED IN EXPLANATION
2559* ---------------- --------------- ------------------------------------
2560* DTYPE_A (global) DESCA( DTYPE_ ) The descriptor type.
2561* CTXT_A (global) DESCA( CTXT_ ) The BLACS context handle, indicating
2562* the NPROW x NPCOL BLACS process grid
2563* A is distributed over. The context
2564* itself is global, but the handle
2565* (the integer value) may vary.
2566* M_A (global) DESCA( M_ ) The number of rows in the distribu-
2567* ted matrix A, M_A >= 0.
2568* N_A (global) DESCA( N_ ) The number of columns in the distri-
2569* buted matrix A, N_A >= 0.
2570* IMB_A (global) DESCA( IMB_ ) The number of rows of the upper left
2571* block of the matrix A, IMB_A > 0.
2572* INB_A (global) DESCA( INB_ ) The number of columns of the upper
2573* left block of the matrix A,
2574* INB_A > 0.
2575* MB_A (global) DESCA( MB_ ) The blocking factor used to distri-
2576* bute the last M_A-IMB_A rows of A,
2577* MB_A > 0.
2578* NB_A (global) DESCA( NB_ ) The blocking factor used to distri-
2579* bute the last N_A-INB_A columns of
2580* A, NB_A > 0.
2581* RSRC_A (global) DESCA( RSRC_ ) The process row over which the first
2582* row of the matrix A is distributed,
2583* NPROW > RSRC_A >= 0.
2584* CSRC_A (global) DESCA( CSRC_ ) The process column over which the
2585* first column of A is distributed.
2586* NPCOL > CSRC_A >= 0.
2587* LLD_A (local) DESCA( LLD_ ) The leading dimension of the local
2588* array storing the local blocks of
2589* the distributed matrix A,
2590* IF( Lc( 1, N_A ) > 0 )
2591* LLD_A >= MAX( 1, Lr( 1, M_A ) )
2592* ELSE
2593* LLD_A >= 1.
2594*
2595* Let K be the number of rows of a matrix A starting at the global in-
2596* dex IA,i.e, A( IA:IA+K-1, : ). Lr( IA, K ) denotes the number of rows
2597* that the process of row coordinate MYROW ( 0 <= MYROW < NPROW ) would
2598* receive if these K rows were distributed over NPROW processes. If K
2599* is the number of columns of a matrix A starting at the global index
2600* JA, i.e, A( :, JA:JA+K-1, : ), Lc( JA, K ) denotes the number of co-
2601* lumns that the process MYCOL ( 0 <= MYCOL < NPCOL ) would receive if
2602* these K columns were distributed over NPCOL processes.
2603*
2604* The values of Lr() and Lc() may be determined via a call to the func-
2605* tion PB_NUMROC:
2606* Lr( IA, K ) = PB_NUMROC( K, IA, IMB_A, MB_A, MYROW, RSRC_A, NPROW )
2607* Lc( JA, K ) = PB_NUMROC( K, JA, INB_A, NB_A, MYCOL, CSRC_A, NPCOL )
