[OMPI users] Strange errors when running mpirun

[Justin Chang]

Dear all,

So I upgraded/updated my Homebrew on my Macbook and installed Open MPI
2.0.1 using "brew install openmpi". However, when I open up a terminal
and type "mpirun -n 1" I get the following messages:

~ mpirun -n 1
[Justins-MacBook-Pro-2.local:20793] [[13318,0],0] bind() failed on
error Address already in use (48)
[Justins-MacBook-Pro-2.local:20793] [[13318,0],0] ORTE_ERROR_LOG:
Error in file oob_usock_component.c at line 228
--
No executable was specified on the mpirun command line.

Aborting.
--


I have never seen anything like the first two lines. I also installed
python and mpi4py via pip, and when I still get the same messages:

~ python -c "from mpi4py import MPI"
[Justins-MacBook-Pro-2.local:20871] [[13496,0],0] bind() failed on
error Address already in use (48)
[Justins-MacBook-Pro-2.local:20871] [[13496,0],0] ORTE_ERROR_LOG:
Error in file oob_usock_component.c at line 228

But now if I add "mpirun -n 1" I get the following:

~ mpirun -n 1 python -c "from mpi4py import MPI"
[Justins-MacBook-Pro-2.local:20935] [[13560,0],0] bind() failed on

Clearly something is wrong here. I already tried things like "rm -rf
$TMPDIR/openmpi-sessions-*" but said directory keeps reappearing and
the error persists. Why does this happen and how do I fix it? For what
it's worth, here's some other information that may help:

~ mpicc --version
Apple LLVM version 8.0.0 (clang-800.0.38)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: 
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I tested Hello World with both mpicc and mpif90, and they still work
despite showing those two error/warning messages.

Thanks,
Justin

Maybe I’m missing something, but “mpirun -n 1” doesn’t include the name of an 
application to execute.

The error message prior to that error indicates that you have some cruft 
sitting in your tmpdir. You just need to clean it out - look for something that 
starts with “openmpi”

Re: [OMPI users] Strange errors when running mpirun

[Justin Chang]

"mpirun -n 1" was just to demonstrate that I get those error messages.
I ran a simple helloworld.c and it still gives those two messages.

I did delete openmpi-sessions-* from my $TMPDIR but it doesn't solve
the problem. Here's my $TMPDIR:

there's a different directory I need to look for?

Try removing the “pmix” entries as well

I tried that and also deleted everything inside $TMPDIR. The error

 The error message prior to that error indicates that you have some cruft 
 sitting in your tmpdir. You just need to clean it out - look for something 
 that starts with “openmpi”

Justin,

i do not see this error on my laptop

which version of OS X are you running ?

can you try to

Re: [OMPI users] OMPI users] Still "illegal instruction"

[Mahmood Naderan]

Although this problem is not related to OMPI *at all*, I think it is good
to tell the others what was going on. Finally, I caught the illegal
instruction :)

Briefly, I built the serial version of Siesta on the frontend and ran it
directly on the compute node. Fortunately, "x/i $pc" from GDB showed that
the illegal instruction was a FMA3 instruction. More detail is available at
https://gcc.gnu.org/ml/gcc-help/2016-09/msg00084.html

According to the Wikipedia,


   - *FMA4* is supported in AMD
    processors
   starting with the Bulldozer
   
   architecture. FMA4 was realized in hardware before FMA3.
   - *FMA3* is supported in AMD processors starting with the Piledriver
   
   architecture and Intel 
   starting with Haswell processors
    and
Broadwell
   processors
    since
   2014.

Therefore, the frontend (piledriver) inserts a FMA3 instruction while the
compute node (Bulldozer) doesn't recognize it.

The solution was (as stated by guys) building Siesta on the compute node. I
have to say that I tested all related programs (OMPI
​,​
Scalapack, OpenBLAS
​) sequentially on the compute node in order to find who generate the
illegal instruction.

Anyway... thanks a lot for your comments. Hope this helps others in the
future.
​

Thx for sharing, quite interesting. But does this mean, that there is no 
working command line flag for gcc to switch this off (like -march=bdver1 what 
Gilles mentioned) or to tell me what he thinks it should compile for?

For pgcc there is -show and I can spot the target it discovered in the 
USETPVAL= line.

Well that didn't work. maybe I messed somethings since I did recompile the
programs multiple times with different configs and options. I will try one
more time.

Re: [OMPI users] Strange errors when running mpirun

[Gilles Gouaillardet]

Justin,


the root cause could be the length of $TMPDIR that might cause some path 
being truncated.


you can check that by simply using a custom $TMPDIR that has the same 
size than the original one



which version of OSX are you running ?

this might explain why Nathan nor i were able to reproduce the issue, 
and i'd like to understand why this


issue went undetected by Open MPI


Cheers,


Gilles

"mpirun -n 1" was just to demonstrate that I get those error messages.
I ran a simple helloworld.c and it still gives those two messages.

I did delete openmpi-sessions-* from my $TMPDIR but it doesn't solve

~ cd $TMPDIR
~ pwd

there's a different directory I need to look for?
