Hello,
I have compiled vasp.6.4.1 on our HPC cluster.
When I run the NaCl example (from the /testsuite/tests) I get an error in the output :
[1688024082.874154] [n017:228578:0] ib_iface.c:947 UCX ERROR Invalid active_width on mlx5_0:1: 16
Abort(1614991) on node 0 (rank 0 in comm 0): Fatal error in PMPI_Init_thread: Other MPI error, error stack:
MPIR_Init_thread(143)........:
MPID_Init(1310)..............:
MPIDI_OFI_mpi_init_hook(1901):
create_endpoint(2593)........: OFI endpoint open failed (ofi_init.c:2593:create_endpoint:Input/output error)
I am not sure if the problem is in the cluster or else in my compilation.
I will be grateful for your help.
Attached is the makefile.include which was used for the compilation, and a tar of the running folder with the PBS submit script and the input and output files.
Thank a lot
Amihai

Re: UCX ERROR Invalid active_width on mlx5_0:1: 16
Hi,
Can you please provide information about the HPC cluster like the processor type and RAM?
Is the error occurring for all examples that you have tried or only NaCl?
A google search of " UCX ERROR Invalid active_width" provides only
https://github.com/openucx/ucx/issues/4556
https://forums.developer.nvidia.com/t/u ... 7-9/206236
Have you tried the possible solutions provided there?

Re: UCX ERROR Invalid active_width on mlx5_0:1: 16
Hi,
The same error occurs in every run. That is why I tried a simple test.
The cluster has Lenovo compute-nodes with processors : Intel(R) Xeon(R) Gold 6230 CPU @ 2.10GHz
384G RAM in each node, and InfiniBand network.
I compiled with the Intel compiler oneapi2022.
Regarding the links you provided, I observe that in my case, command
ucx_info -d
doesn't show any error. Its output is attached.
Thanks, Amihai

Re: UCX ERROR Invalid active_width on mlx5_0:1: 16
Is the error also occurring in non-parallel calculation with "mpirun -np 1"? Are you running with OpenMP, i.e., with OMP_NUM_THREADS>1?

Re: UCX ERROR Invalid active_width on mlx5_0:1: 16
Yes, the run failed also with "mpirun -np 1".
It also failed with the same error when I put
export OMP_NUM_THREADS=12
mpirun -np 12 ...
I thought that it is a problem of the Intel oneapi compiler, so I downloaded and installed the latest version, and recompiled VASP with it,
It didn't solve the problem, the run fails with the same error.

Please see the output of ucx_info -d. It looks like Device: mlx5_0:1 is OK :

Re: UCX ERROR Invalid active_width on mlx5_0:1: 16
Hi,
I will ask my colleagues if they have an idea of what could be the problem. Meanwhile you could try what is mentioned in the last post of
https://forums.developer.nvidia.com/t/u ... 9/206236/4
where it is suggested to add "soft memlock unlimited" and "hard memlock unlimited" in /etc/security/limits.d/rdma.conf. I guess it is not related and won't help, but try it just in case.

Re: UCX ERROR Invalid active_width on mlx5_0:1: 16
Hi,
For running a calculation, do you load the required Intel modules or set the environment variables correctly?
Does the problem also occur if OpenMP is switched off with "export OMP_NUM_THREADS=1"?

Hi,
Thank you for your replies, I think that the problem is with the compute-nodes. I have asked the cluster support to check that with the cluster integrator.
