SUBROUTINE STIMB3( LINE, NM, MVAL, NN, NVAL, NK, KVAL, NLDA,
$ LDAVAL, TIMMIN, A, B, C, RESLTS, LDR1, LDR2,
$ NOUT )
*
* -- LAPACK timing routine (version 3.0) --
* Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
* Courant Institute, Argonne National Lab, and Rice University
* March 31, 1993
*
* .. Scalar Arguments ..
CHARACTER*( * ) LINE
INTEGER LDR1, LDR2, NK, NLDA, NM, NN, NOUT
REAL TIMMIN
* ..
* .. Array Arguments ..
INTEGER KVAL( * ), LDAVAL( * ), MVAL( * ), NVAL( * )
REAL A( * ), B( * ), C( * ), RESLTS( LDR1, LDR2, * )
* ..
*
* Purpose
* =======
*
* STIMB3 times the Level 3 BLAS routines.
*
* Arguments
* =========
*
* LINE (input) CHARACTER*80
* The input line that requested this routine. The first six
* characters contain either the name of a subroutine or a
* generic path name. The remaining characters may be used to
* specify the individual routines to be timed. See ATIMIN for
* a full description of the format of the input line.
*
* NM (input) INTEGER
* The number of values of M contained in the vector MVAL.
*
* MVAL (input) INTEGER array, dimension (NM)
* The values of the matrix row dimension M.
*
* NN (input) INTEGER
* The number of values of N contained in the vector NVAL.
*
* NVAL (input) INTEGER array, dimension (NN)
* The values of the matrix column dimension N.
*
* NK (input) INTEGER
* The number of values of K contained in the vector KVAL.
*
* KVAL (input) INTEGER array, dimension (NK)
* The values of K. K is used as the intermediate matrix
* dimension for SGEMM (the product of an M x K matrix and a
* K x N matrix) and as the dimension of the rank-K update in
* SSYRK and SSYR2K.
*
* NLDA (input) INTEGER
* The number of values of LDA contained in the vector LDAVAL.
*
* LDAVAL (input) INTEGER array, dimension (NLDA)
* The values of the leading dimension of the array A.
*
* TIMMIN (input) REAL
* The minimum time a subroutine will be timed.
*
* A (workspace) REAL array, dimension (LDAMAX*NMAX)
* where LDAMAX and NMAX are the maximum values permitted
* for LDA and N.
*
* B (workspace) REAL array, dimension (LDAMAX*NMAX)
*
* C (workspace) REAL array, dimension (LDAMAX*NMAX)
*
* RESLTS (output) REAL array, dimension (LDR1,LDR2,NLDA)
* The timing results for each subroutine over the relevant
* values of M, N, K, and LDA.
*
* LDR1 (input) INTEGER
* The first dimension of RESLTS. LDR1 >= max(1,NM,NK).
*
* LDR2 (input) INTEGER
* The second dimension of RESLTS. LDR2 >= max(1,NN).
*
* NOUT (input) INTEGER
* The unit number for output.
*
