Lapack install

[moulaye]

Hy,

I try to install Lapack on my computer ( hp pavillon zv5000, OS : Linux fedora core (2.6.9.- 1.667) ). After typing "make all" all source are compiled but the execution of testing executables is not done (ex : xlintsts)
Is there somebody who can help me ?
Excuse for my english
Thanks.

Hello,
[ Thanks for the effort to speak English !]

that's weird.
What message do you have?
Are you speaking of the testing or the timing?

If you want to force the testing, you can go in the TESTING directory and type 'make' (that should have been done automatically however).

Hello,
I speak about testing .
In the directory TESTING there is only two executables: xlintsts and xeigtsts. After type make the execution of one executable (xlintsts or xeigtsts) begin, but after several minutes not of result. What appears abnormal to me I force the program to stop.

Thanks for your answer.

[Julien Langou]

so there should have eight executables not two

xlintsts (single - linear system)
xlintstd (double - linear system)
xlintstc (single complex - linear system)
xlintstz (double complex - linear system)
xeigtsts (single - eigen system)
xeigtstd (double - eigen system)
xeigtstc (single complex - eigen system)
xeigtstz (double complex - eigen system)

so first you are missing some buddies....


then try
cd TESTING
./xlintsts < stest.in

this works?

if yes try:
./xeigtsts < nep.in
./xeigtsts < sep.in
./xeigtsts < svd.in
./xeigtsts < sec.in
./xeigtsts < sed.in
./xeigtsts < sgg.in
./xeigtsts < sgd.in
./xeigtsts < ssb.in
./xeigtsts < ssg.in
./xeigtsts < sbal.in
./xeigtsts < sbak.in
./xeigtsts < sgbal.in
./xeigtsts < sgbak.in
./xeigtsts < sbb.in
./xeigtsts < glm.in
./xeigtsts < gqr.in
./xeigtsts < gsv.in
./xeigtsts < lse.in

if this works, I think I have a guess...
what's your shell?

echo $SHELL

??

Anyway just try:

setenv SHELL bash; make

we are using redirection in the command line that are not standard for some SHELL (csh for example)

Hello Julien,

I followed your indiactions but i have the same problem.
After typing the command setenv SHELL bash;make
First i have this message: "bash: setenv: command not found",
The compilation process continue, the execution begin by :
./xeigtsts < sdv.in > ssvd.out 2>&1
and no result appears.

[Julien Langou]

no need to set your SHELL to bash, you are already using bash, so forget about the setenv.

ok so you should have a bunch of *.out files that have been created no?

If the makefile is at the step you describe:
./xeigtsts < sdv.in > ssvd.out 2>&1
this means that you should have
stest.out
snep.out
ssep.out
for sure in the TESTING directory.

Open those files, everything looks ok?

then if the make does not work... what does all this give (see below)?
I hope this should be ok.
If something hangs let me know which one and please try the others.

./xeigtsts < nep.in
./xeigtsts < sep.in
./xeigtsts < svd.in
./xeigtsts < sec.in
./xeigtsts < sed.in
./xeigtsts < sgg.in
./xeigtsts < sgd.in
./xeigtsts < ssb.in
./xeigtsts < ssg.in
./xeigtsts < sbal.in
./xeigtsts < sbak.in
./xeigtsts < sgbal.in
./xeigtsts < sgbak.in
./xeigtsts < sbb.in
./xeigtsts < glm.in
./xeigtsts < gqr.in
./xeigtsts < gsv.in
./xeigtsts < lse.in

[moulaye]

Hello,
There are many error messages in those 3 files (i don't understand those message).
For example in stest.out all test value are INF for SGE routine,is it normal?
At beigin of the file (snep.out,ssep.out,stest.out) there are (i thing ) machine' s parameters:
Relative machine underflow is taken to be 0.000000E+00
Relative machine overflow is taken to be -0.368935E+20
Relative machine precision is taken to be 0.000000E+00
Those parameters are normal?
Because i don't know how to attach a file to this message ,i can't send you those files(snep.out,ssep.out,stest.out).
Thanks again for help

[Julien Langou]

hello,
so yes you can stop everything. this is not good at all.
Can you just copy-paste your make.inc please?

[Julien Langou]

I really do not know what's the problem.
The installation is pretty standard on all the Linux boxes and your make.inc is ok.

(1) so you can do a make clean of everything, nothing's good here.
(2) can you give me the output of

make install

(3) what is your machine
(4) what is your compiler version

My machine is hp pavillon zv5000 ,the procesor is AMD 64 Athlon
The OS is Linux fedora core (2.6.9 -1.667) ,i don't know what version of compilator is associated to this lLinux version.
Thank you very much.

[Julien Langou]

pefect... so you definetely have a problem,
it's important for us to know the version of the compiler, just type
g77 --version
It's nice if you can answer. It will help us.

So if you are running out of time with this installation, what you can do
id just install the RPM. I am sure Fedora provides good RPM for lapack and
reference blas. (It's a bit the solution of the poor though, sorry about that.)

Typing command g77 --version gave this result
GNU Fortran (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)

What is RPM ?

[moulaye]

Hello,
Is in lapack a routine which solve a linear system with iterative method (ex: bicgstab or gmres)? :?:

[Julien Langou]

No there is not. LAPACK is focused on dense linear algebra problems (i.e. problems where all the elements of the matrix are stored in some predefined storage format GE, BD, SY, SP,....).
Iterative methods (GMRES, BiCGStab) are less attractive for this class of problems. You will find a software review on the web page:
http://www.netlib.org/utk/people/JackDongarra/la-sw.html
if you go in the item 'sparse iterative solvers' and just make your pick.
