Dear Amber User,
Recently we have installed Amber 20 in
Fujitsu HPC machine. While running amber jobs using pmemd.cuda_DPFP.MPI
routine with 4 nodes (each node has 24 processors), it gives the following
error. Please give your valuable suggestions to rectify that error.
*--------------------------------------------------------------------------By
default, for Open MPI 4.0 and later, infiniband ports on a deviceare not
used by default. The intent is to use UCX for these devices.You can
override this policy by setting the btl_openib_allow_ib MCA parameterto
true. Local host: comp-gpu0 Local adapter: mlx5_0

invoking MPI_ABORT causes Open MPI to kill all MPI processes.You may or may
not see output from other processes, depending onexactly when Open MPI

them.--------------------------------------------------------------------------[comp-gpu0.local:226093]
