Hi, I have a very large, very old FORTRAN code that I work with. The code is quite messy and I was wondering if I can speed up execution time by finding subroutines that code execution spends the most time in. Is there any kind of software I can use to see where the code spends most of the... (1 Reply)
Hi,
I am new to this forum and do not know whether this is the appropriate place to post this question. Anyway am trying my luck.
I have a fortran program swanhcat.ftn, which is part of a wave modelling system. There is also a file hcat.nml which is required to run this program. The program's... (9 Replies)
Hi there,
I had run into some fortran code to modify. Obviously, it was written without thinking of high performance computing and not parallelized... Now I would like to make the code "on track" and parallel. After a whole afternoon thinking, I still cannot find where to start. Can any one... (3 Replies)
I am using doxygen for documenting my fortran code.

Hi
I am reading a book about Fortran 90 and I write the following code, to test my understanding of the first chapter. I have a problem with the last section of the code with deals with an IF, ELSEIF, and GOTO statements. Here is my Code

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).
Machine: MBP OSX 10.14.3, default bash terminal, calling '#!/usr/local/bin/dash'...
This is purely a fun project to see if it is possible in PURE... (3 Replies)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
