blacs scalapack


Hi everyone,

In order to run a program in paralell, I have to install blacs and scalapack. I have downloaded both on opensuse 11 with gfortran compiler. But it seems that I have to modify some files according to my system.

Could anyone let me know in detaiol what I should do, cause I could not do it alone reading the installation guide.

Regards,
Catrina

Your question is very vague. You're going to have to provide more information than "I have to modify some files according to my system".

You don't say what version/distro of Linux you have, or what you've tried so far, so how can anyone tell you what you need to do? If you have the installation guide, that's the best resource to go by. If you have specific questions or problems, post them along with complete information.

Welcome to Linux Questions.

1) There are some ( few ) packages for Suse 11 :
# 'zypper search lapack blas libblas blacs scalapack'
> > lapack, lapack-man, liblapack3,
libblas3, blas, blas-man .
( The selection is much better for other Linux's
e.g. Debian, Ubuntu, Fedora, PCLinuxOS )

2) gfortran : If you need g77, f77 then cd /usr/bin
# ln -s gfortran-4.3 g77, # ln -s gfortran-4.3 f77 .

3) And the "file editing instructions" :
Google .. blacs linux .. EDIT > >
EDIT http://www.nottingham.ac.uk/is/servi...calapack.phtml

http://www.netlib.org/blacs/
http://www.netlib.org/blacs/archives/
http://www.netlib.org/blacs/BLACS/Papers.html

Google .. LaPack linux ..
http://seehuhn.de/pages/linear

4) Another option for changing files : use the source and the patches
[blacs-mpi_1.1.orig.tar.gz], [blacs-mpi_1.1-28.diff.gz] from
http://packages.debian.org/lenny/blacs1gf-lam
and other black's just search 'blacs' on the site.

[lapack_3.1.1.orig.tar.gz], [lapack_3.1.1-1.diff.gz]
http://packages.debian.org/lenny/liblapack-dev
and 'scalapack' is searchable too.

The patches are supposed to make the editing :
'patch -p0 < "file.diff"

Good Luck !
....

blacs scalapack

Hello all,

Sorry, I have no systematic knowledge of linux and also I am very new to the forum.

I have already downloaded 'blacs' and 'scalapack' from the websites you have mentioned.

As I said I am using opensuse 11, gfortran compiler and openmpi. Now I want to install blacs and scalapack.

In the Installation guide of blcs it has said that we have to modify the suitable Bmakes. Therefore I have modified 'Bmake.MPI-LINUX' and I have put it at the end of this thread. Please kindly have a look at it.

After this modification, I have to write 'make', but still it asks me to modify bmake ?!?! Could you kindly let me know what I should do to have blcs installed?

Regards,

# If you know something about your system, you may make it easier for the

I intended to show an alternative instruction for scalapack,
this is the correct address ( instead of the misprint )

http://www.nottingham.ac.uk/is/servi...calapack.phtml

See 5 : "Edit Bmake.inc as follows"

Scalapack, blacs is software, I never have worked with, may
be I can have a look at it in a few days.

And an administrative note: please use size and colour tags
sparingly - that [ size=3 ] rendered the post almost unreadable.
