hi,
I hope that this is not too late yet, but I attend to the university of Minnessota and there is a computer lab I pass by every day, and they run Ubuntu 12.04, in fact they have several labs...

the way I deal whit that kind of things is completely different. Any time I install emacs, I install auctex and reftex at the same time. reftex handles all the labels and cross-references and it does...

did you guys try starting matlab from the command line? usually the matlab installer aks during the installation if you want to add a symbolic link to /usr/bin which is all what you need in order to...

from what I have read in the previous posts, I think that the best option is Inkscape. Don't forget that in case that you have to include some math in your poster, you can typeset everything directly...

I agree with you, but I think that the analogy is accurate. without the chassis, the thing wouldn't run, but If it not were for the far better user experience and attention to details, Ubuntu...

sure, canonical takes something like this, and gives to the users something like this, which they would even ship for free to people all over the world. I wonder why Ubuntu is so popular. I only hope...

I decided to learn a bit of C++ and now, I definitely and absolutely prefer fortran 90. check the following fortran 90 code for matrix times vector multiplication and compare it to the equivalent C++...

you can actually embed a movie in a beamer presentation. the code for doing that is below

\usepackage{multimedia}
\begin{document}
\movie[width=6cm, height=6cm, poster]{}{animation.avi}

now,...

did you try using the menu file>save path?
I'm not sure that I really understand what is your problem.

yes indeed. as I stated in a previous post I learned about the "parallel universe" of programming with MPI. however MPI is much harder to use than openMP. and from what I've been reading you only...

that sounds interesting. meanwhile I'm investing some time in learning openMP. I'm really surprised about how easily you can paralellize a code for using it with a multicore machine. considering how...

I thought that you and I agreed with respect to the parallelization capabilities of both languages:

ssam was arguing about C being better than fortran in this respect (parallelization), basing his...

I don't see why that wouldn't be possible with fortran. also, using gotos etc seems a bit like using outdated bad programming practices to me.
gotos were common with the fortran 77 standard, but...

here is the change you did, but in fortran version:

program test
integer :: i,j,k,n
real*8 :: x
n=10000
!$OMP PARALLEL do
do i=1,n
do j =1,n
do k=1,n

I think that this comment summarizes what I have learned in this thread and answers my original question. thanks

the execution times below


fortran
7:54:38.40 (7 hours 54 minutes 38.4 seconds)
C
7:54:06.71 (7 hours 54 minutes 6.7 seconds)

were obtained when compiled as shown here

definitely!. no doubt about that

now, that is a very interesting question. I have little knowledge about parallelization. I have used the MPI library before, and as far as I know, its use is...

this is chinese to me :D, I'm not really a programmer. If matlab were as fast as fortran or C, I wouldn't bother using anything else.

I regularly used that flag, until a couple of years ago, when...

using those flags (-msse2 -mfpmath=sse) increased the execution time for both C and Fortran executables, and also made them run in similar times. I'll look into that and post the best results with a...

ftfy ;)

great!! that's really good stuff. I'm running two executables compiled with those tags right now, and I'll post the results tomorrow. Also, given that computing the square root has been source of...

below is a summary of the execution times for all the test I have run until now:


fortran (no optimization)
4:46:48.45 (4 hours, 46 min, 48 seconds)
fortran (full optimization)
4:18:08.29 ...

yes! I agree. a comparison like that is what I would really like to see.

this is a very sophisticated question actually. I use vectorial operations in fortran all the time but as I stated...

my apologies for my C-C++ ignorance, and thanks for the info. If you read the original post carefully, you will notice that times for 2 fortran executables were reported, one compiled with full...

I completely agree with you. I would only recommend fortran to anybody interested in scientific computing, who wants to do some heavy computations. In my case, I use matlab for manipulating and...
