TAU2VTF(1) Tools TAU2VTF(1)NAME
tau2vtf - convert TAU tracefiles to vampir tracefiles
SYNOPSIS
tau2vtf [-nomessage] [-v] [[-a] [-fa]] {tau_tracefile} {tau_eventfile} {vtf_tracefile}
DESCRIPTION
This program is generated when TAU is configured with the -vtf=<vtf_dir> option.
The tau2vtf trace converter takes a single tau_tracefile (*.trc) and tau_eventfile (*.edf) and produces a corresponding vtf_tracefile
(*.vtf). The input files and output file must be specified in that order. Multi-file TAU traces must be merged before conversion.
The default output file format is VTF3 binary. If the output filename is given as the .vpt.gz type, rather than .vpt, the output file will
be gzipped. There are two additional output format options. The command line argument '-a' produces the vtf file output in ASCII VTF3
format. The command line argument '-fa' produces the vtf file output in the FAST ASCII VTF3 format. Note that these arguments are mutually
exclusive.
OPTIONS -nomessage Suppresses printing of message information in the trace.
-v Verbose mode sends trace event descriptions to the standard output as they are converted.
-a Print the vtf file output in the human-readable VTF3 ASCII format
-fa Print the vtf file in the simplified human-readable FAST ASCII VTF3 format
EXAMPLES
The program must be run with the tau trace, tau event and vtf output files specified in the command line in that order. Any additional
arguments follow. The following will produce a VTF, app.vpt, from the TAU trace and event files merged.trc and tau.edf trace file:
tau2vtf merged.trc tau.edf app.vpt
The following will convert merged.trc and tau.edf to a gzipped FAST ASCII vampir tracefile app.vpt.gz, with message events omitted:
tau2vtf merged.trc tau.edf app.vpt.gz -nomessage -fa

NAME
ZLARZ - applie a complex elementary reflector H to a complex M-by-N matrix C, from either the left or the right
SYNOPSIS
SUBROUTINE ZLARZ( SIDE, M, N, L, V, INCV, TAU, C, LDC, WORK )
CHARACTER SIDE
INTEGER INCV, L, LDC, M, N
COMPLEX*16 TAU
COMPLEX*16 C( LDC, * ), V( * ), WORK( * )
PURPOSE
ZLARZ applies a complex elementary reflector H to a complex M-by-N matrix C, from either the left or the right. H is represented in the
form
H = I - tau * v * v'
where tau is a complex scalar and v is a complex vector.
If tau = 0, then H is taken to be the unit matrix.
To apply H' (the conjugate transpose of H), supply conjg(tau) instead tau.
H is a product of k elementary reflectors as returned by ZTZRZF.
ARGUMENTS
SIDE (input) CHARACTER*1
= 'L': form H * C
= 'R': form C * H
M (input) INTEGER
The number of rows of the matrix C.
N (input) INTEGER
The number of columns of the matrix C.
L (input) INTEGER
The number of entries of the vector V containing the meaningful part of the Householder vectors. If SIDE = 'L', M >= L >= 0, if
SIDE = 'R', N >= L >= 0.
V (input) COMPLEX*16 array, dimension (1+(L-1)*abs(INCV))
The vector v in the representation of H as returned by ZTZRZF. V is not used if TAU = 0.
INCV (input) INTEGER
The increment between elements of v. INCV <> 0.
TAU (input) COMPLEX*16
The value tau in the representation of H.
C (input/output) COMPLEX*16 array, dimension (LDC,N)
On entry, the M-by-N matrix C. On exit, C is overwritten by the matrix H * C if SIDE = 'L', or C * H if SIDE = 'R'.
LDC (input) INTEGER
The leading dimension of the array C. LDC >= max(1,M).
WORK (workspace) COMPLEX*16 array, dimension
(N) if SIDE = 'L' or (M) if SIDE = 'R'
