Re: [OMPI users] MPI_Init_thread hangs in OpenMPI 1.7.1 when using --enable-mpi-thread-multiple

[Ralph Castain]

Yes, I expect it will continue to hang until 1.7.4 is released. Should be
fixed there, though we'll check.

Hi,

I now tried using --enable-opal-multi-threads (I added an "s" in the end, since 
"--enable-opal-multi-thread" was not recognized by the configure script).

However, my test code still hangs in the same way as before.

To be clear, I now configure like this:

Any other ideas?
Are there other configure options that must be used together with

Hello!

I would like to report what seems to be a bug in MPI_Init_thread in OpenMPI 
1.7.1.

The bug can be reproduced with the following test program 
(test_mpi_thread_support.c):
===
#include 
#include 
int main(int argc, const char* argv[]) {
int provided = -1;
printf("Calling MPI_Init_thread...\n");
MPI_Init_thread(NULL, NULL, MPI_THREAD_MULTIPLE, );
printf("MPI_Init_thread returned, provided = %d\n", provided);
MPI_Finalize();
return 0;
}
===

When trying to run this when OpenMPI was configured with 
--enable-mpi-thread-multiple, the program hangs when trying to run using 
anything more than one process.

Steps I use to reproduce this in Ubuntu:

(1) Download openmpi-1.7.1.tar.gz

(2) Configure like this:
./configure --enable-mpi-thread-multiple

(3) make

(4) Compile test program like this:
mpicc test_mpi_thread_support.c

(5) Run like this:
mpirun -np 2 ./a.out
Then you see the following two lines of output:
Calling MPI_Init_thread...
Calling MPI_Init_thread...
And then it hangs.

MPI_Init_thread did not hang in earlier OpenMPI versions (for example it worked 
in 1.5.* and 1.6.*), so it seems like a bug introduced in 1.7.

The description above shows how I reproduce this in Ubuntu on my local desktop 
computer, but the same problem exists for the OpenMPI 1.7.1 installation at the 
UPPMAX computer center where I wan to run my code in the end. I don't know all 
details about how they installed it there, but I know they set 
--enable-mpi-thread-multiple. So maybe it hangs in 1.7.1 on any computer

Not in the immediate future, but hopefully not too far into infinity - however,

 The solution (as suggested by Ralph) is to use the following four 
 configure options together:
 ./configure --enable_event_thread_support --enable_opal_multi_threads 
 --enable_orte_progress_threads --enable_mpi_thread_multiple
 
 So, apparently the --enable_mpi_thread_multiple option cannot be used by 
 itself, it must be combined with the other three options, otherwise 
 MPI_Init_thread will hang.

I can confirm that mpi program still hangs if one uses these options

Re: [OMPI users] MPI_Init_thread hangs in OpenMPI 1.7.1 when using --enable-mpi-thread-multiple

[Ralph Castain]

While I'm glad it worked, having it depend on orte progress thread wasn't done 
by intent, hence the comment in the configure help output. I'm not seeing any 
problems with using that option, but please let us know if you run into 
something. It hasn't been as fully tested as we'd like.

 Hello!
 
 I would like to report what seems to be a bug in MPI_Init_thread in 
 OpenMPI 1.7.1.
 
 The bug can be reproduced with the following test program 
 (test_mpi_thread_support.c):
 ===
 #include 
 #include 
 int main(int argc, const char* argv[]) {
 int provided = -1;
 printf("Calling MPI_Init_thread...\n");
 MPI_Init_thread(NULL, NULL, MPI_THREAD_MULTIPLE, );
 printf("MPI_Init_thread returned, provided = %d\n", provided);
 MPI_Finalize();
 return 0;
 }
 ===
 
 When trying to run this when OpenMPI was configured with 
 --enable-mpi-thread-multiple, the program hangs when trying to run using 
 anything more than one process.
 
 Steps I use to reproduce this in Ubuntu:
 
 (1) Download openmpi-1.7.1.tar.gz
 
 (2) Configure like this:
 ./configure --enable-mpi-thread-multiple
 
 (3) make
 
 (4) Compile test program like this:
 mpicc test_mpi_thread_support.c
 
 (5) Run like this:
 mpirun -np 2 ./a.out
 Then you see the following two lines of output:
 Calling MPI_Init_thread...
 Calling MPI_Init_thread...
 And then it hangs.
 
 MPI_Init_thread did not hang in earlier OpenMPI versions (for example it 
 worked in 1.5.* and 1.6.*), so it seems like a bug introduced in 1.7.
 
 The description above shows how I reproduce this in Ubuntu on my local 
 desktop computer, but the same problem exists for the OpenMPI 1.7.1 
 installation at the UPPMAX computer center where I wan to run my code in 
 the end. I don't know all details about how they installed it there, but I 
 know they set --enable-mpi-thread-multiple. So maybe it hangs in 1.7.1 on 
 any computer as long as you use MPI_THREAD_MULTIPLE. At least I have not 
 seen it work anywhere.
 
 Do you agree that this is a bug, or am I doing something wrong?
 
 Best regards,
 Elias

Re: [OMPI users] MPI_Init_thread hangs in OpenMPI 1.7.1 when using --enable-mpi-thread-multiple

[Elias Rudberg]

This has now been solved.

The solution (as suggested by Ralph) is to use the following four  
configure options together:
./configure --enable_event_thread_support --enable_opal_multi_threads  
--enable_orte_progress_threads --enable_mpi_thread_multiple


So, apparently the --enable_mpi_thread_multiple option cannot be used  
by itself, it must be combined with the other three options, otherwise  
MPI_Init_thread will hang.

Hi,

I now tried using --enable-opal-multi-threads (I added an "s" in the  
end, since "--enable-opal-multi-thread" was not recognized by the  
configure script).


However, my test code still hangs in the same way as before.

To be clear, I now configure like this:
./configure --enable-mpi-thread-multiple --enable-opal-multi-threads

but the problem remains: MPI_Init_thread still hangs when trying to  
run the test case with -np 2.


Any other ideas?
Are there other configure options that must be used together with  
--enable-mpi-thread-multiple to make it work?

Hmmm...well, your code runs fine for me:

Ralphs-iMac:mpi rhc$ mpirun -n 2 ./thread_init
Calling MPI_Init_thread...
Calling MPI_Init_thread...
MPI_Init_thread returned, provided = 3
MPI_Init_thread returned, provided = 3
Ralphs-iMac:mpi rhc$

I think the key, however, is that you also have to configure with  
--enable-opal-multi-thread.

Re: [OMPI users] MPI_Init_thread hangs in OpenMPI 1.7.1 when using --enable-mpi-thread-multiple

[Elias Rudberg]

Hi,

I now tried using --enable-opal-multi-threads (I added an "s" in the  
end, since "--enable-opal-multi-thread" was not recognized by the  
configure script).


However, my test code still hangs in the same way as before.

To be clear, I now configure like this:
./configure --enable-mpi-thread-multiple --enable-opal-multi-threads

but the problem remains: MPI_Init_thread still hangs when trying to  
run the test case with -np 2.


Any other ideas?
Are there other configure options that must be used together with  
--enable-mpi-thread-multiple to make it work?


Best regards,
Elias

Hmmm...well, your code runs fine for me:

Ralphs-iMac:mpi rhc$ mpirun -n 2 ./thread_init
Calling MPI_Init_thread...
Calling MPI_Init_thread...
MPI_Init_thread returned, provided = 3
MPI_Init_thread returned, provided = 3
Ralphs-iMac:mpi rhc$

I think the key, however, is that you also have to configure with  
--enable-opal-multi-thread.
