New MPI error with Intel 2019.1, unable to run MPI hello world

Paul_K_2 — Tue, 13 Nov 2018 16:51:58 GMT

After upgrading to update 1 of Intel 2019 we are not able to run even an MPI hello world example. This is new behavior and e.g. a spack installed gcc 8.20 and OpenMPI have no trouble on this system. This is a single workstation and only shm needs to work. For non-mpi use the compilers work correctly. Presumably dependencies have changed slightly in this new update?

I have encountered the same problem. Have you got any solutions yet?

Hi Paul,

Hi Paul,

Could you send us an output from an "ifconfig" command, please?

Thank you!

I have encountered the same problem / same error message running an application between nodes.

Configuration: Scientific Linux 7.5, Intel latest version

Installing Intel Parallel

Paul_K_2 — Mon, 19 Nov 2018 16:23:57 GMT

Installing Intel Parallel Studio XE Cluster Edition from scratch (clean install) did not change this problem or error. i.e. It is unrelated to the update procedure 2019.0 -> 2019.1

Hi Paul,

Dmitry_G_Intel — Mon, 19 Nov 2018 17:49:50 GMT

Hi Paul,

Did you see the same error with IMPI 2019 Gold?

I have two possible methods that could help you:

- set FI_SOCKETS_IFACE=eth0 (or any IP interfaces that works correctly) environment variable.

- set FI_PROVIDER=tcp environment variable (only applicable for IMPI 2019 U1). This will switch to another OFI provider (i.e. IMPI access to the network), but this provider is available as a Technical Preview and will replace OFI/sockets provider in the future releases.

If you still have the same problems, please, collect logs with FI_LOG_LEVEL=debug set. The logs will be printed to standard error (stderr) output.

Thank you!

Dmitry

Thanks Dmitry. Seeting FI_LOG

Paul_K_2 — Mon, 19 Nov 2018 18:12:12 GMT

Thanks Dmitry. Setting FI_LOG_LEVEL=debug was very helpful:

Using export FI_PROVIDER=tcp solves the crash for us. Hopefully this has no performance impact for on-node messages. I also hope update 2 can avoid this environment/configuration variable requirement.

Hi Paul,

Dmitry_G_Intel — Mon, 19 Nov 2018 20:12:35 GMT

Hi Paul,

Sorry for inconvenience. Yes, we are going to identify the root cause of the problem.

FI_PROVIDER=tcp has better performance number in compare to FI_PROVIDER=sockets (current default OFI provider for Intel MPI 2019 Gold and U1), but FI_PROVIDER=tcp is a technical preview due to some stability issues.

You are right. TCP provider doesn't impact performance for intra-node communication, because SHM transport is used by default. You can ensure that shm is used for intra- and OFI for inter-node communications by setting I_MPI_FABRICS=shm:ofi.

By the way, I have one more question to you that can help our team to indentify the root cause -- Did you try to set FI_SOCKETS_IFACE to any interface? If not, could you try it, please (please, unset FI_PROVIDER or set to FI_PROVIDER=sockets, we should ensure that OFI/sockets provider is used in your test)?

It would be great to check it for all values: docker0; eth0; eth1.

Thank you in advance!

Dmitry

Looks like it "lost" the default sockets provider in the update.

Hi Paul,

Dmitry_G_Intel — Tue, 20 Nov 2018 04:29:51 GMT

Hi Paul,

Thank you! We appreciate your help.

It looks like that setting either FI_PROVIDER=sockets or FI_PROVIDER=tcp solves your problem, doesn't it?

IMPI 2019 should use sockets OFI provider (i.e. FI_PROVIDER=sockets) by default, but this is not case due to some reason.

I seem to have the same (or similar) problem (2019 Update 5), except that it only occurs for when run on a E5410. It runs fine with E5-2660, Gold 6130 or Gold 6138, and also runs fine with comp2015/impi/5.0.2.044. The various environmental options suggested don't work (for me).

Similar thing happens to me.

Similar thing happens to me. Just installed the 2019.5.281 version of MPI Library. I use the Intel Parallel Studio XE 2019, the latest version on the Visual Studio. Running the MPI code results in the following message:

[mpiexec@Sebastian-PC] bstrap\service\service_launch.c (305): server rejected credentials
[mpiexec@Sebastian-PC] bstrap\src\hydra_bstrap.c (371): error launching bstrap proxy
[mpiexec@Sebastian-PC] mpiexec.c (1898): error setting up the boostrap proxies

With -localonly I can run the code but all cores are executing the same thing as the master code (everybody runs the same) and have the same id. Any ideas how to fix this?
