Hello

I was able to correctly install and test OpenMPI 4.0.1 functionality on my Mac. 
However, I am running into another problem. I am running an astrophysical code 
named PLUTO which uses certain old routines which have been discontinued in the 
newer MPI versions. As a result, I face errors during the ‘make’ process. The 
error log is attached as a text file. Can someone guide me as to how I can fix 
that and make use of new routines?

Thanks
Riddhi

Leo,
  Thanks for the info. That is interesting.  And yes, Having a CUDA aware MPI 
API list would be very useful.

Hi Junchao,





First, for your second question, the answer is here: 
https://www.mail-archive.com/users@lists.open-mpi.org/msg33279.html. I know 
this because I also asked it earlier  It'd be nice to have this documented in 
the Q though.



As for your first question, I am also interested. It'd be nice for Open MPI 
core devs to keep the supported API list up-to-date. We recently added support 
of CUDA-aware MPI to mpi4py, and such a list is important for us to keep track 
upstream support so that we know whether a test fails due to lack of 
CUDA-awareness or because we messed up (much less likely).



Thanks.




Sincerely,
Leo

Another question: If MPI_Allgatherv(const void *sendbuf, int sendcount, 
MPI_Datatype sendtype, void *recvbuf, const int recvcounts[],const int 
displs[], MPI_Datatype recvtype, MPI_Comm comm) is cuda aware, are recvcounts,

Re: [OMPI users] **URGENT: Error during testing

[Riddhi A Mehta via users]

Hi

I followed the exact procedure stated in this link: 
http://www.science.smith.edu/dftwiki/index.php/Install_MPI_on_a_MacBook.


It runs correctly until this line : mpicc -o hello helloWorld.c
After which it gives me the error when I do mpirun.

Thank you

Riddhi

Is there any chance that the fact that Riddhi appears to be trying to execute 
an uncompiled hello.c could be the problem here?

It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_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):

  pmix server init failed
  --> Returned value Bad parameter (-5) instead of ORTE_SUCCESS

I tried to google this error and the only thing I found was to change the 
TMPDIR name to a shorter name. But I don’t think I understand what it’s asking 
me to do. Kindly help since I am not able to understand what went wrong in one 
month and mpirun stopped working.
