Patrick,
the test points to a leak in the way the interconnect component (pml/ucx
? pml/cm? mtl/psm2? btl/openib?) handles the datatype rather than the
datatype engine itself.
What interconnect is available on your cluster and which component(s)
are used?
mpirun --mca pml_base_verbose 1
Hi Gilles,
The interconnect is Qlogic infiniband QDR. I was unable to compile
latest UCX release on this CentOS6 based Rocks Cluster distribution when
deploying OpenMPI 4.0.5 but I do not search a lot: I'm currently
deploying a new cluster on CentOS8 and this old cluster will move to
CentOS8 too a
