Provided blacs does not work

[CrocoDuck o'Ducks]

Hi there!

I am trying to build the docker file 'acousto-2.0_dockerfile' by issuing
this command:

docker build - < acousto-2.0_dockerfile

However, the build fails at this stage:

checking for Cblacs_pinfo in -lblacsCinit... no
checking for Cblacs_pinfo in -lblacsC... no
checking for Cblacs_pinfo in -lmpiblacsCinit... no
checking for Cblacs_pinfo in -lblacsCinit_MPI... no
checking for Cblacs_pinfo in -lblacsCinit-openmpi... no
configure: error: Provided blacs does not work!

It is perhaps worth to mention that I had the same exact error while
trying to build from source a native installation, despite being sure I
sorted out all dependencies. See my docker info below:

Hi CrocoDuck,
I'll check the procedure this afternoon and let you know.
Best wishes

Hi CrocoDuck,

try the following

• in the dockerfile change "FROM debian" to "FROM debian:8.6"

• from the directory where the dockerfile is, issue the command
  docker build -t name-of-image . -f ./acousto-2.0_dockerfile

Let me know ...

Umb

Hi Umb,

I have same issue here. The difference is that i am using native build under centos 7.4, do you know how to solver this problem?

Thanks & Regards,
James

[Fred Voisin]

Yep, FROM debian:8.6 is working on ubuntu 18.04 :)
Thank's.
Fred

[Umberto Iemma]

Hi James,

if you are trying to compile outside a docker cintainer it's not the same issue. CrocoDuck problem was a purely dockerfile problem.

Could you please post the config.log ?

[James Marine]

Hi Umberto,

See attached. Is there any requirement on which version of lib and openmpi should be used?

By the way, is there any update on AcouSTO? I noted that there has been long time no update.

Thanks & Regards,
James

[Umberto Iemma]

My group is working on a major update that will take some time to be released.
Soon, we will publish minor updates to guarantee compatibility with the latest MPI release
and fix some installation problem.

It seems that there is something wrong in your installation.

• blas seems to be not present
• MPI seems to be compiled without fortyran support

Check carefully your setup and send a feedback

U

[Umberto Iemma]

please try with the mpi new and sclapack new oprtions

[Umberto Iemma]

mmmh, strange... Later this afternoon I'll try to reproduce your probloem here. Now I have to teach ...

[Umberto Iemma]

I've tried on a Centos 7.4 VM and works perfectly !

Just install openmpi3 suite and lapack devel package from standard centos repository.
Then follow these steps

1) Download latest epel-release rpm from

http://download-ib01.fedoraproject.org/pub/epel/7/x86_64/

2) Install epel-release rpm:

# rpm -Uvh epel-release*rpm

3) Install scalapack-openmpi3-static rpm package:

# yum install scalapack-openmpi3-static

Then, configure acousto with

./configure --enable-mppinew --enable-scalapack_new

Now you can compile and instal with

make && sudo make install

Best,
Umb

Hello,
I'm trying to install with ubuntu 20.04. I got the following error with configure :
configure: MPI version used: 1.6.x

configure: error: Provided blacs does not work!

Could you please help me solve this problem.

Hello, I have the same problem: blacs not working in current Ubuntu 20.04

However, I found that in Ubuntu 16.04 there was
libblacs-openmpi-dev
Now, in Ubuntu 20.04, there is only a "virtual" package, "provided" by
libscalapack-openmpi-dev

[...]

By the way, the other installation option in docker, with the modification FROM debian:8.6 as described above by Umberto lemma was also successful for me.

[fred voisin]

Hello,

I’m sorry I’m still using ubuntu 18.04.
As you said it should be easy to fix, probably just a link.
Thank’s for your positive experience with using docker option.

Now, in Ubuntu 20.04, there is only a "virtual" package:
libblacs-openmpi-dev
which is "provided" by
libscalapack-openmpi-dev
and the binary files are provided from
libscalapack-openmpi2.1

Perhaps one should modify the configure.ac file so that these libraries are properly linked; however I had no success with this up to now.

Maybe for some expert this would be trivial...

Hello, thanks for the reply :-)

I got it compiled in Ubuntu 20.04.

• Compile and install ScaLAPACK 2.1.0 from sources (with cmake and default configuration:

cp SLmake.inc.example SLmake.inc 

this gives libscalapack.a in /usr/local/lib

• For AcouSTO, run ./configure with following options (of course, all necessary libraries must be installed):

./configure --prefix=/usr/local \
   --enable-mpinew --enable-scalapack_new \
   --with-libconfig=/usr/lib/x86_64-linux-gnu \
   --with-blas=/usr/lib/x86_64-linux-gnu/blas \
   --with-lapack=/usr/lib/x86_64-linux-gnu/lapack \
   --with-scalapack=/usr/local/lib

• The newest MPI library has changed its syntax, and make gives an error in

src/mpi/mpiutils.c

I tried a preliminary fix and replaced all occurrences of MPI_UB with MPI_INT.

Hopefully, it will also calculate, let's see...

Best, Max

[Nazalli choucha]

Thanks for you help. I installed the docker image with changing FROM debian to FROM debian:8.6 as. It worked well !

[Max Funk]

Hallo, I wanted to finish this investigation about Ubuntu installation; meanwhile I did it better...

• The "BLACS" not found message in newer library versions can mean, that "libscalapack.a" is not found. Because "blacs" is now contained in "scalapack". However, it is not necessary to rebuild scalapack. Instead, the shared libraries in the package "libscalapack-openmpi-dev" are sufficient. However, a link is needed:

ln -s /usr/lib/x86_64-linux-gnu/libscalapack-openmpi.so /usr/lib/x86_64-linux-gnu/libscalapack.so

• The ./configure command can be simply:

 ./configure --prefix=/usr/local \
             --enable-mpinew --enable-scalapack_new \
             --with-libs=/usr/lib/x86_64-linux-gnu

• There is still the error due to the "old" code in mpiutils.c, However, as described in https://www.open-mpi.org/faq/?category=mpi-removed , this should be fixed by replacing

 #define OMPI_ENABLE_MPI1_COMPAT 0

with

#define OMPI_ENABLE_MPI1_COMPAT 1

in the file

 /usr/lib/x86_64-linux-gnu/openmpi/include/mpi.h

That's all.

I wrote a shell script from the template of the dockerfile, which makes everything (package download, mpi setting, compile, install) out of the box (attachment). On my Windows10 - Linux subsystem it works; however no whatever warranty...

Best regards

[Max Funk]

Here my install script again, tested with a complete vanilla Ubuntu 20.04 and two bugs fixed.

[Max Funk]

Tried out Ubuntu 18.04 and current Debian (10.6) shell and the install script (see previous post) worked fine :-)

[Umberto Iemma]

Dear Max
thank you for your contribution! We are about to release v2.5 and we will test your script also with it. This will be the last Acousto version, then something new will happen .... Thank you again

[Max Funk]

Happy, that I could contribute. And looking forward to your new version :-)

[Max Funk]

Finally, I did some code cleaning and better commenting in my script.
The function is not changed.

Best regards

[Kevin Michel]

Hey Max :)
I tried the installation procedure on my own and also used your .sh file. Unfortunately, I get the following error:

collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:755: acousto] Error 1
make[1]: Leaving directory '/home/railon/Shell-Installation/acousto-2.0/src'
make: *** [Makefile:352: all-recursive] Error 1

I took a look inside the makefile in the src directory, but I cannot figure out, what the problem is. The line of code I guess is causing the error is:

acousto$(EXEEXT): $(acousto_OBJECTS) $(acousto_DEPENDENCIES) $(EXTRA_acousto_DEPENDENCIES)
@rm -f acousto$(EXEEXT)
** $(AM_V_CCLD)$(acousto_LINK) $(acousto_OBJECTS) $(acousto_LDADD) $(LIBS)**

Could you help me with that?
Thank you really much!

[Kevin Michel]

Maybe the question is better adressed to its developer @Umberto_Iemma :D
