MPI having bad performance in user mode, runs perfectly in root

[Jeremie_Lagraviere]

Hi everyone,

This is very probably an installation issue of the Parallel Studio 2016 (update 1) on my system...So here are the details:

I have installed Intel Parallel Studio 2016 (update 1) on my server: two sockets with Intel Xeon processors (Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz), running Ubuntu 12.04 (I know that this is not supposed to be a supported OS...at least this is what the requirements checking thingy in the Parallel Studio install says...).

The problem is really simple:

If I am logged in as a regular user and if I use mpirun to run any program...The program execution takes forever. Looking at htop it seems that the used cores spend their time in "kernel" mode.

If I am logged in as root, using the same mpirun command, the programs runs perfectly.

I tried a "violent" solution by changing the permission of the directory /opt/intel to chmod ugo+rwx

But this did not anything.

Thanks in advance for your help!

TL;DR; Intel mpirun, runs normally in root, but when using a regular user it is extremely slow.

Hi Jeremie,

Could you please provide more details about your hung MPI run - try to run it with I_MPI_DEBUG=100 and I_MPI_HYDRA_DEBUG=1 variables and provide the output (with the command line and environment variables).

Also try the following scenarios:
mpirun ... hostname
mpirun ... IMB-MPI1 pingpong

It may be an environmental problem - check your SSH settings (SSH should be passwordless).

BTW you wrote:

If I am logged in as a regular user and if I use mpirun to run any program...The program execution takes forever.

So has the MPI scenario finally finished?

[Jeremie_Lagraviere]

EDIT: From the debug output it looks like it's a ssh problem (?)...the thing is that I am using MPI on only one node..I should not need SSH at all, right ?

__

Just to be clear, I am not using any SSH in my experience:

I run MPI on only one machine.

The program I am running is a kernel from the NAS Benchmarks.

__

So far I did not wait for the scenario to finish...because it is really slow. (Of course running as root the programs finishes without any problem. and with good performances).

I left a kernel of the NAS Benchmark to run over the night...it is still not done running...so I guess there is no point in waiting longer :)

__

Is it possible that the problem can come from the fact that I installed Intel Parallel Studio as root ? (Anyway, I had no choice to do otherwise, as I wanted to install Intel Parallel Studio in /opt/intel

__

With the two environment variables I_MPI_DEBUG=100 and I_MPI_HYDRA_DEBUG=1  and running the following command: 

/opt/intel/compilers_and_libraries_2016.1.150/linux/mpi/intel64/bin/mpirun -n 16 ./cg.C.16

Here is the output:

Hi Jeremie,

As far as I see your MPI application has been started successfully (SSH isn't used for such local runs) but it got stuck for some reasons (maybe due to memory exhaustion - for example, got stuck in swap area). You said that it worked fine under root so I'd suspect different system limits for the user and root accounts - could you please compare 'ulimit -a' for both users and align it if necessary.

[Jeremie_Lagraviere]

Thanks for your reply :)

Both ulimit -a seems to be the same:

Hi Jeremie,

As far as I see your scenario got stuck into the application so I'd recommend you to try to simplify the MPI run - try to run less number of processes (2, 4, 8) and/or check and vary the parameters of the MPI application (if any).

Also try the following test scenario under root/user accounts and provide the output for both cases:
I_MPI_DEBUG=100 I_MPI_HYDRA_DEBUG=1 mpirun -n 2 IMB-MPI1 pingpong

Another suggestion is to check SELinux status and try to disable it - potentially it may be a reason of the user/root difference.

[Jeremie_Lagraviere]

I don't think I need to try on less core number as I already tried the same program compiled for 2 cores with the same problems.

Here is the result of mpirun -n 2 IMB-MPI1 pingpong (with the correct environment variables, and running as root)

About SELinux I do not think that it is running on the system I am using (Ubuntu 12.04)

The directory /selinux exists, however it is completely empty.

Hi Jeremie,

Do I correctly understand that IMB pingpong hang for 2nd scenario (under the user)? If yes could you please try the same scenario with I_MPI_SHM_LMT=shm variable?

[Jeremie_Lagraviere]

Thanks again for your help:

Here is the result of mpirun -n 2 IMB-MPI1 pingpong

using these variables: I_MPI_SHM_LMT=shm I_MPI_DEBUG=100 I_MPI_HYDRA_DEBUG=1

run by regular user (not root)

Hi Jeremie,

It looks like I_MPI_SHM_LMT=shm has helped. Could you please try this W/A for the initial scenario?

I've reproduced the problem on our cluster - looks like Ubuntu* specificity. I'll submit an internal ticket for this problem. Thanks for the reporting.

[Frank_Illenseer]

Hi All,

since we are running into exactly same issue as discussed in this thread here, I'd like to ask, if there was any additional outcome from that internal ticket that was created in January by Artem in post #11? - Or should I also create a ticket in Intel Premier Support now about this?

We are currently experiencing this issue with latest Ubuntu version 16.10 (but also 16.04 shows it) and using IMPI 5.1.3.180

Should one then set this environment variable by default on any Ubuntu system? - Or what is Intel's advice?
Also asking, if one has jobs spanning multiple hosts - what is the situation there?

Thanks and best regards,
Frank

[Frank_Illenseer]

Hi Artem (Intel),

what was the outcome of the ticket that you created (mentioned in post #12 above)?
Couly ou please elaborate on this with respect to my questions in post #13 above?

Thanks and best regards,
Frank

[Artem_R_Intel1]

Hi Frank,

Sorry for the late answer.
You can find some recipes for the issue in the Intel® MPI Library Release Notes:

    - On some Linux* distributions, the Intel(R) MPI Library will fail for non-root
      users due to security limitations.
      This has been seen on Ubuntu* 12.04, and could impact other
      distributions and versions as well.  Two workarounds have been identified
      for this issue.
      o Enable ptrace for non-root users with:
        echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
      o Or, revert the Intel(R) MPI Library to an earlier shared memory
        mechanism which is not impacted by setting:
        I_MPI_SHM_LMT=shm

[Pieter_V_1]

We have encountered the same issue and can confirm that enabling ptrace for non-root users works around the problem.

Since we provide an application for users that do not necessarly have the permissions to enable ptrace, we have identified a third workaround. From within the application one can disable the ptrace restrictions by calling

prctl(PR_SET_PTRACER, PR_SET_PTRACER_ANY, 0, 0, 0);

[KRISTOPHER_K_]

I can add that this issue appears with Arch Linux as well. The workarounds mentioned here solve the issue.
