Two matrix types may be used for timing. The number of types is set in the parameter NMODE and the matrix types are set in the vector MODES, using the following key: 2. BREAK1 D(1:N-1)=1 and D(N)=1.0/COND in SLATMS 3. GEOM D(I)=COND**(-(I-1)/(N-1)) in SLATMS These numbers are chosen to correspond with the matrix types in the test code. 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 and N contained in the vectors MVAL and NVAL. The matrix sizes are used in pairs (M,N). MVAL (input) INTEGER array, dimension (NM) The values of the matrix row dimension M. NVAL (input) INTEGER array, dimension (NM) The values of the matrix column dimension N. 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 of LDA and N. COPYA (workspace) REAL array, dimension (LDAMAX*NMAX) TAU (workspace) REAL array, dimension (min(M,N)) WORK (workspace) REAL array, dimension (3*NMAX) IWORK (workspace) INTEGER array, dimension (2*NMAX) RESLTS (workspace) REAL array, dimension (LDR1,LDR2,NLDA) The timing results for each subroutine over the relevant values of MODE, (M,N), and LDA. LDR1 (input) INTEGER The first dimension of RESLTS. LDR1 >= max(1,NM). LDR2 (input) INTEGER The second dimension of RESLTS. LDR2 >= max(1,NM). NOUT (input) INTEGER The unit number for output. ===================================================================== Parameter adjustments */ --mval; --nval; --ldaval; --a; --copya; --tau; --work; --iwork; reslts_dim1 = *ldr1; reslts_dim2 = *ldr2; reslts_offset = 1 + reslts_dim1 * (1 + reslts_dim2 * 1); reslts -= reslts_offset; /* Function Body Extract the timing request from the input line. */ s_copy(path, "Single precision", (ftnlen)1, (ftnlen)16); s_copy(path + 1, "QP", (ftnlen)2, (ftnlen)2); atimin_(path, line, &c__1, subnam, timsub, nout, &info, (ftnlen)3, ( ftnlen)80, (ftnlen)6); if (! timsub[0] || info != 0) { goto L80; } /* Check that M <= LDA for the input values. */ s_copy(cname, line, (ftnlen)6, (ftnlen)6); atimck_(&c__1, cname, nm, &mval[1], nlda, &ldaval[1], nout, &info, ( ftnlen)6); if (info > 0) { io___8.ciunit = *nout; s_wsfe(&io___8); do_fio(&c__1, cname, (ftnlen)6); e_wsfe(); goto L80; } /* Set the condition number and scaling factor for the matrices to be generated. */ dmax__ = 1.f; cond = 1.f / slamch_("Precision"); /* Do for each pair of values (M,N): */ i__1 = *nm; for (im = 1; im <= i__1; ++im) { m = mval[im]; n = nval[im]; minmn = min(m,n); /* Do for each value of LDA: */ i__2 = *nlda; for (ilda = 1; ilda <= i__2; ++ilda) { lda = ldaval[ilda]; for (imode = 1; imode <= 2; ++imode) { mode = modes[imode - 1]; /* Generate a test matrix of size m by n using the singular value distribution indicated by MODE. */ i__3 = n; for (i__ = 1; i__ <= i__3; ++i__) { iwork[n + i__] = 0; /* L10: */ } slatms_(&m, &n, "Uniform", iseed, "Nonsymm", &tau[1], &mode, & cond, &dmax__, &m, &n, "No packing", ©a[1], &lda, &work[1], &info); /* SGEQPF: QR factorization with column pivoting */ slacpy_("All", &m, &n, ©a[1], &lda, &a[1], &lda); icopy_(&n, &iwork[n + 1], &c__1, &iwork[1], &c__1); ic = 0; s1 = second_(); L20: sgeqpf_(&m, &n, &a[1], &lda, &iwork[1], &tau[1], &work[1], & info); s2 = second_(); time = s2 - s1; ++ic; if (time < *timmin) { slacpy_("All", &m, &n, ©a[1], &lda, &a[1], &lda); icopy_(&n, &iwork[n + 1], &c__1, &iwork[1], &c__1); goto L20; } /* Subtract the time used in SLACPY and ICOPY. */ icl = 1; s1 = second_(); L30: s2 = second_(); untime = s2 - s1; ++icl; if (icl <= ic) { slacpy_("All", &m, &n, ©a[1], &lda, &a[1], &lda); icopy_(&n, &iwork[n + 1], &c__1, &iwork[1], &c__1); goto L30; } time = (time - untime) / (real) ic; ops = sopla_("SGEQPF", &m, &n, &c__0, &c__0, &c__1) ; reslts_ref(imode, im, ilda) = smflop_(&ops, &time, &info); /* L40: */ } /* L50: */ } /* L60: */ } /* Print tables of results */ io___27.ciunit = *nout; s_wsfe(&io___27); do_fio(&c__1, subnam_ref(0, 1), (ftnlen)6); e_wsfe(); if (*nlda > 1) { i__1 = *nlda; for (i__ = 1; i__ <= i__1; ++i__) { io___28.ciunit = *nout; s_wsfe(&io___28); do_fio(&c__1, (char *)&i__, (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ldaval[i__], (ftnlen)sizeof(integer)); e_wsfe(); /* L70: */ } } io___29.ciunit = *nout; s_wsle(&io___29); e_wsle(); sprtb5_("Type", "M", "N", &c__2, modes, nm, &mval[1], &nval[1], nlda, & reslts[reslts_offset], ldr1, ldr2, nout, (ftnlen)4, (ftnlen)1, ( ftnlen)1); L80: return 0; /* End of STIMQP */ } /* stimqp_ */ #undef reslts_ref #undef subnam_ref
