You will not be able to generate VT traces, and since you unlikely want to
do that, you will likely be just fine

 mpirun has detected an attempt to run as root.
 Running at root is *strongly* discouraged as any mistake (e.g., in

 You can override this protection by adding the --allow-run-as-root

Re: [OMPI users] openmpi-1.10.3 cross compile configure options for arm-openwrt-linux-muslgnueabi on x86_64-linux-gnu

[Mahesh Nanavalla]

Hi Gilles,

Thanks for reply,

If i do *--disable-vt *while configuring the openmpi-1.10.3 ,

the size of the installation directory reduced 70MB to 9MB.

will it effect anything?

 Hi,

 You did *not* specify the following options to configure, right?
 Specifying all these will cause a problem.

   --disable-mmap-shmem
   --disable-posix-shmem
   --disable-sysv-shmem

 Please send the output of the following command.

   mpirun --allow-run-as-root -np 1 --mca shmem_base_verbose 100
 helloworld

 And, give us the config.log file which is output in the
 top directory where configure is executed.
 Put it on the web or send the compressed (xz or bzip2 is better) file.

Re: [OMPI users] openmpi-1.10.3 cross compile configure options for arm-openwrt-linux-muslgnueabi on x86_64-linux-gnu

[Gilles Gouaillardet]

vt is a contrib that produces traces to be used by VaMPIr
IIRC, this has been removed from Open MPI starting v2.0.0

Worst case scenario is it will fail to build, and most likely case is you
do not need it, so you can save some build time with --disable-vet

Cheers,

Gilles

[Mahesh Nanavalla]

Hi all

it's working.

I forget to copy all openmpi libs and bin to target board

Now it's working fine...

Thank u all.

Thank u very much for your support

root@OpenWrt:/# cp /openmpi/lib/libopen-rte.so.12 /usr/lib/

mpirun has detected an attempt to run as root.
Running at root is *strongly* discouraged as any mistake (e.g., in
defining TMPDIR) or bug can result in catastrophic damage to the OS
file system, leaving your system in an unusable state.

You can override this protection by adding the --allow-run-as-root
option to your cmd line. However, we reiterate our strong advice
against doing so - please do so at your own risk.

Re: [OMPI users] openmpi-1.10.3 cross compile configure options for arm-openwrt-linux-muslgnueabi on x86_64-linux-gnu

[Kawashima, Takahiro]

Hi,

You did *not* specify the following options to configure, right?
Specifying all these will cause a problem.

  --disable-mmap-shmem
  --disable-posix-shmem
  --disable-sysv-shmem

Please send the output of the following command.

  mpirun --allow-run-as-root -np 1 --mca shmem_base_verbose 100 helloworld

And, give us the config.log file which is output in the
top directory where configure is executed.
Put it on the web or send the compressed (xz or bzip2 is better) file.

Regards,
Takahiro Kawashima

It looks like opal_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  opal_shmem_base_select failed
  --> Returned value -1 instead of OPAL_SUCCESS

Kindly help me.

Re: [OMPI users] openmpi-1.10.3 cross compile configure options for arm-openwrt-linux-muslgnueabi on x86_64-linux-gnu

[Kawashima, Takahiro]

Hi,

> How to cross compile *openmpi *for* arm *on* x86_64 pc.*
> 
> *Kindly provide configure options for above...*

You should pass your arm architecture name to the --host option.

Example of my configure options for Open MPI, run on sparc64,
built on x86_64:

  --prefix=...
  --host=sparc64-unknown-linux-gnu
  --build=x86_64-cross-linux-gnu
  --disable-mpi-fortran
  CC=your_c_cross_compiler_command
  CXX=your_cxx_cross_compiler_command

If you need Fortran support, it's a bit complex. You need to
prepare a special file and pass it to the --with-cross option.

A cross mpicc command is not built automatically with the
options above. There are (at least) three options to compile
your MPI programs.

(A) Manually add -L, -I, and -l options to the cross gcc command
(or another compiler) when you compile a MPI program.
The options you should pass is written in
$installdir/share/openmpi/mpicc-wrapper-data.txt.
In most cases, -I$installdir/include -L$installdir/lib -lmpi
will be sufficient.

(B) Use the --enable-script-wrapper-compilers option on configure
time, as you tried. This method may not be maintained well
in the Open MPI team so you may encounter problems.
But you can ask them on this mailing list.

(C) Build Open MPI for x86_64 natively, copy the opal_wrapper
command, and write wrapper-data.txt file.
This is a bit complex task. I'll write the procedure on
GitHub Wiki when I have a time.

Hi everyone,

I'm trying to cross compile openmpi-1.10.3

configure options...



./configure --enable-orterun-prefix-by-default

--disable-mpi-fortran
--enable-shared
--disable-mmap-shmem
--disable-posix-shmem
--disable-sysv-shmem
--disable-dlopen
configuring,make  install successfully.
I added
$export PATH="$PATH:/home/$USER/Workspace/ARM_MPI/openmpi/bin/"
$export 
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/Workspace/ARM_MPI/openmpi/lib/"


$export PATH="$PATH:/home/$USER/Workspace/ARM_MPI/openmpi/bin/" >> 
/home/$USER/.bashrc
$export 
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/$USER/Workspace/ARM_MPI/openmpi/lib/" >> 
/home/$USER/.bashrc


But while compiling as below i'am getting error
