Re: [OMPI users] srun and openmpi

[Ralph Castain]

Run the program only once - it can be in the prolog of the job if you like. The 
output value needs to be in the env of every rank.

You can reuse the value as many times as you like - it doesn't have to be 
unique for each job. There is nothing magic about the value itself.

Re: [OMPI users] srun and openmpi

[Michael Di Domenico]

How early does this need to run? Can I run it as part of a task
prolog, or does it need to be the shell env for each rank?  And does
it need to run on one node or all the nodes in the job?

 It would really help if you included the error message. Otherwise, all 
 I can do is guess, which wastes both of our time :-(

 My best guess is that the port reservation didn't get passed down to 
 the MPI procs properly - but that's just a guess.

Re: [OMPI users] srun and openmpi

Should have also warned you: you'll need to configure OMPI --with-devel-headers 
to get this program to build/run.

Re: [OMPI users] srun and openmpi

[Ralph Castain]

Well, I couldn't do it as a patch - proved too complicated as the psm system 
looks for the value early in the boot procedure.

What I can do is give you the attached key generator program. It outputs the 
envar required to run your program. So if you run the attached program and then 
export the output into your environment, you should be okay. Looks like this:

$ ./psm_keygen
OMPI_MCA_orte_precondition_transports=0099b3eaa2c1547e-afb287789133a954
$ 

You compile the program with the usual mpicc.

Let me know if this solves the problem (or not).

 I followed what i found on the web with enabling the MpiPorts config
 in slurm and using the --resv-ports switch, but I'm getting an error

 I'm using Slurm 2.1.15 and Openmpi 1.5 w/PSM
 
 I'm sure I'm missing a step.

Re: [OMPI users] srun and openmpi

[Ralph Castain]

Ah, yes - that is going to be a problem. The PSM key gets generated by mpirun 
as it is shared info - i.e., every proc has to get the same value.

I can create a patch that will do this for the srun direct-launch scenario, if 
you want to try it. Would be later today, though.

Re: [OMPI users] srun and openmpi

[Michael Di Domenico]

Well maybe not horray, yet.  I might have jumped the gun a bit, it's
looking like srun works in general, but perhaps not with PSM

With PSM i get this error, (at least now i know what i changed)

Error obtaining unique transport key from ORTE
(orte_precondition_transports not present in the environment)
PML add procs failed
--> Returned "Error" (-1) instead of "Success" (0)

Turn off PSM and srun works fine

 It would really help if you included the error message. Otherwise, all I 
 can do is guess, which wastes both of our time :-(

 My best guess is that the port reservation didn't get passed down to the 
 MPI procs properly - but that's just a guess.

 I followed what i found on the web with enabling the MpiPorts config
 in slurm and using the --resv-ports switch, but I'm getting an error
 from openmpi during setup.
 
 I'm using Slurm 2.1.15 and Openmpi 1.5 w/PSM
 
 I'm sure I'm missing a step.

Re: [OMPI users] srun and openmpi

[Michael Di Domenico]

Yes that's true, error messages help.  I was hoping there was some
documentation to see what i've done wrong.  I can't easily cut and
paste errors from my cluster.

Here's a snippet (hand typed) of the error message, but it does look
like a rank communications error

ORTE_ERROR_LOG: A message is attempting to be sent to a process whose
contact information is unknown in file rml_oob_send.c at line 145.
*** MPI_INIT failure message (snipped) ***
orte_grpcomm_modex failed
--> Returned "A messages is attempting to be sent to a process whose
contact information us uknown" (-117) instead of "Success" (0)

This msg repeats for each rank, an ultimately hangs the srun which i
have to Ctrl-C and terminate

I have mpiports defined in my slurm config and running srun with
-resv-ports does show the SLURM_RESV_PORTS environment variable
getting parts to the shell
