Thanks Ralph,
There’s no MCA parameters in my environment at all. Here’s the contents of openmpi-mca-params.conf: mpi_leave_pinned = 0 hwloc_base_binding_policy = core rmaps_base_mapping_policy = core hwloc_base_mem_alloc_policy = local_only shmem_mmap_enable_nfs_warning = 0 pml = ^yalla mtl = ^mxm mtl_mxm_np = 0 coll = ^fca coll_fca_enable = 1 coll_fca_np = 0 There are the same as for 1.10.0 (it’s a symlink to the same file). There’s nothing there that I can see that would cause it to think that I was asking for multiple CPUs per proc. Getting rid of all of the ‘policy’ options doesn’t change the behaviour, except it then says [r51:18193] mca:rmaps:rr: mapping no-span by Socket for job [25745,1] slots 32 num_procs 32 [r51:18193] mca:rmaps:rr: found 2 Socket objects on node r51 [r51:18193] mca:rmaps:rr: assigning proc to object 0 -------------------------------------------------------------------------- A request for multiple cpus-per-proc was given, but a directive was also give to map to an object level that has less cpus than requested ones: #cpus-per-proc: 1 number of cpus: 0 map-by: BYSOCKET:NOOVERSUBSCRIBE Please specify a mapping level that has more cpus, or else let us define a default mapping that will allow multiple cpus-per-proc. -------------------------------------------------------------------------- Forcing it to use ppr instead of rr with ppr:1:core:PE=1 using the MCA parameters above gives this: [r51:18320] AVAILABLE NODES FOR MAPPING: [r51:18320] node: r51 daemon: 0 [r51:18320] node: r58 daemon: 1 [r51:18320] mca:rmaps:base: computing vpids by slot for job [25616,1] [r51:18320] mca:rmaps:base: assigning rank 0 to node r51 [r51:18320] mca:rmaps:base: assigning rank 1 to node r51 [r51:18320] mca:rmaps:base: assigning rank 2 to node r58 [r51:18320] mca:rmaps:base: assigning rank 3 to node r58 [r51:18320] mca:rmaps: compute bindings for job [25616,1] with policy CORE[4008] [r51:18320] [[25616,0],0] reset_usage: node r51 has 2 procs on it [r51:18320] [[25616,0],0] reset_usage: ignoring proc [[25616,1],0] [r51:18320] [[25616,0],0] reset_usage: ignoring proc [[25616,1],1] [r51:18320] [[25616,0],0] bind_depth: 6 map_depth 2 [r51:18320] mca:rmaps: bind downward for job [25616,1] with bindings CORE -------------------------------------------------------------------------- While computing bindings, we found no available cpus on the following node: Node: r51 Please check your allocation. -------------------------------------------------------------------------- (actually, it’s the regardless of if it’s socket, core, or node). If I get rid of the policy options as above, I get the original error. However, if I do it outside of a PBS job (so no cgroup), it works as I would expect. So have there been any changes in the handling of cpusets?

I'm unaware of any change that would impact you here. For some reason, mpirun believes you are requesting multiple cpus-per-proc, and that seems to be the heart of the problem. Is there an MCA parameter in your environment or default param file, perhaps?
