problem MAGMA-1.2.0 ATLAS-3.10.0 Lapack-3.4.1..help !!!

[ronmarc97]

Hello people, i need your help ...please

I am trying compile testing_ssyevd.cpp from Magma and i get this error
I use the next command lines

gcc -O3 -DADD_ -DGPUSHMEM=200 -I/usr/local/cuda/src/ -I/usr/local/cuda/include -I../include -c testing_ssyevd.cpp -o testing_ssyevd.o
gcc -O3 -DADD_ -DGPUSHMEM=200 -fPIC -Xlinker -zmuldefs -DGPUSHMEM=200 testing_ssyevd.o -o testing_ssyevd -L../lib -lcuda -L/home/ronald/magma-1.2.0/lib/ -lmagma -lmagmablas -lmagma -L/usr/local/cuda/lib64 -L/usr/local/cuda/lib -L/usr/local/cuda/include -L/usr/local/atlas/include -L/home/ronald/lapack-3.4.1/BLAS -lf2c -lgfortran -lstdc++ -lpthread -lblas -lcublas -lcudart -latlas -lsatlas -lf77blas -ldl -lm

And i get the next error:

Anybody can help me? Maybe i've forgotten any library ..i dont know

Tanhks in advance

[Stan Tomov]

Hello,
These functions are from the LAPACK library. LAPACK is a MAGMA dependency and has to be installed or your system and linked.I see you have

Code: Select all

-L/home/ronald/lapack-3.4.1/


but don't have -llapack. Do you have a liblapack.a somewhere in /home/ronald/lapack-3.4.1/?

[ronmarc97]

Hello

Yes, I have the liblapack.a in /home/ronald/lapack-3.4.1/

Now i compiled with this commands lines, and the error is the same

PD:
When i installed the magma (with make)..only some testing functions were compiled like:
testing_zgebrd
testing_zgehrd
testing_zgelqf
testing_zgelqf_gpu
testing_zgemm
testing_zgemv
testing_zgeqlf
testing_zgeqrf
testing_zgeqrf_gpu
testing_zgeqrs3_gpu
and anothers 10 more

But the testing_ssyevd (that i want to use) and the rest were not compiled.

[Stan Tomov]

Hi,
These undefined routines are supposed to be in lapack. Maybe check to see if they are indeed there, e.g.,

Code: Select all

nm liblapack.a | grep ssyevd


If it is not there, probably you have some incomplete version of LAPACK, e.g., something that comes with ATLAS. If it is there, probably just adding -llapack once more at the end will fix the problem.

[ronmarc97]

Hi

I checked:
nm liblapack.a | grep ssyevd
nm: 'liblapack.a': No such file

There is not ssyevd routine in the liblapack.a

I tried adding -llapack once more, but continue with the same error

How i get the complete version of LAPACK, because i downloaded Lapack-3.4.1.tgz....is not it the complete version ??..and downloaded too atlas3.10.0.tar.bz2..
Maybe somentig in the make.inc or Makefile is wrong ???

[mgates3]

Check your nm command. It looks like you didn't give the full path to lapack, so nm is reporting an error. For instance, on my machine it looks like this:

nm /Users/mgates/src/lapack-3.4.2/liblapack.a | grep ssyevd
/Users/mgates/src/lapack-3.4.2/liblapack.a(ssyevd.o):
00000000 T _ssyevd_
U _ssyevd_

[mgates3]

There are some weird things in your make.inc file. First, LIB should just be the libraries themselves, not any directories. The directories go in LIBDIR.

LIBDIR doesn't generally need paths to include directories, only to lib directories.

Generally it's best to use the -lname syntax instead of explicitly listing the library file, libname.a. So delete the two liblapack.a from you LIB.

Your paths to LAPACK look weird. There should be only one path, to the top level lapack directory, not to every sub-directory. That is,

-L/home/ronald/lapack-3.4.1

instead of:

-L/home/ronald/lapack-3.4.1/INSTALL
-L/home/ronald/lapack-3.4.1/SRC
-L/home/ronald/lapack-3.4.1/BLAS
-L/home/ronald/lapack-3.4.1/TESTING

I would try setting:

LIB = -lf2c -lgfortran -lstdc++ -lpthread -lblas -lcublas -lcudart -latlas -lf77blas -lcblas -llapack -fopenmp -lm

LIBDIR = -L/usr/local/atlas/lib -L/usr/local/lib64 -L/opt/acml5.1.0/gfortran64/lib -L/home/ronald/lapack-3.4.1 -L/home/ronald/magma-1.2.0/lib
-L$(CUDADIR)/lib64

Also, if liblapack.a is in both /usr/local/atlas/lib and /home/ronald/lapack-3.4.1, you may have a problem of which one gets chosen. Try listing the lapack-3.4.1 directory first in LIBDIR.

You list paths to ACML and MKL. If you have MKL, you should probably get lapack from MKL rather than compiling it yourself from source. MKL will have better optimized versions of routines.

Finally, magma 1.3 has been out for several months. Generally, you should use the latest version.

Any helps please...i would apreciatte a lot

Try moving lapack directory to the beginning of LIBDIR. (And fix magma-1.2.0 to magma-1.3.0.)

LIBDIR = -L/home/ronald/lapack-3.4.1 -L/usr/local/atlas/lib -L/usr/local/lib64 -L/home/ronald/magma-1.3.0/lib \
-L$(CUDADIR)/lib64

The problem being that ATLAS has liblapack.a, but it is incomplete:
romulus ~> nm /mnt/scratch/sw/atlas-gcc/lib/liblapack.a | grep larnv
romulus ~>

Whereas the full lapack contains these functions:
romulus ~> nm ~/src/lapack-3.4.2/liblapack.a | grep larnv
U slarnv_
U dlarnv_
clarnv.o:
0000000000000000 T clarnv_

Hello again...and thanks a lot !!

I changed de LIBDIR in the magma make.inc

LIBDIR = -L/home/ronald/lapack-3.4.1 -L/usr/local/atlas/lib -L/usr/local/lib64 -L/home/ronald/magma-1.3.0/lib \
-L$(CUDADIR)/lib64

Now gives that error when i tried to install with make:

/home/ronald/lapack-3.4.2/liblapack.a(zgetrf.o): In function `zgetrf_':

Also i chcked the liblapack.a like that:

There is another thing, when i installed the ATLAS, gave the next error when i was running the sanity tests to ensure my libraries are producing correct answers (make check)

sqrtst.o: In function `qrtest':
qrtst.c:(.text+0x11b4): undefined reference to `ATL_C2Fsormqr'

collect2: ld returned 1 exit status
make[3]: *** [xsqrtst] Error 1

Is it possible that the problem is with ATLAS

Again, any help is welcome...thanks a lot partners
