Re: [OMPI users] UFLM only works on a single node???

[Dean Anderson via users]

Also using IB. I tried with options —with-ft ulfm —mca pml ob1 —mca btl_tcp_if_include ib0 —mca btl tcp,sm,self And still hangs. Build was just 5.0.2 (ulfm already on by default): —prefix=xx —with-ucx=pathtoucx1.15 —with-slurm Sent from my iPhone On Mar 24, 2024, at 2:00 PM, George Bosilca <bosi...@icl.utk.edu> wrote:  All the examples work for me on using ULFM ge87f595 compiled with minimalistic options: '--prefix=XXX --enable-picky --enable-debug --disable-heterogeneous --enable-contrib-no-build=vt --enable-mpirun-prefix-by-default --enable-mpi-ext=ftmpi --with-ft=mpi --with-pmi'. I run using ipoib, so I select the sm,self, tcp BTL and the OB1 PML.   George.

The SC-22 Tutorials work just fine, but only on a single node.  If you arrange multiple nodes, it hangs in MPI_Finalize. I attended the SC22 Tutorial and it was not my impression that UFLM only worked if your tasks were all on a single node. Thanks!! Sent from my iPhone
