I am compiling OpenMPI 1.7.3 and 1.7.2 with GCC 4.8.1 but I'm unable to activate
some binding policy at compile time.
ompi_info -a shows:
MCA hwloc: parameter "hwloc_base_binding_policy" (current value: "", data
source: default, level: 9 dev/all, type: string)
Policy for binding processes [none (default) |
hwthread | core | l1cache | l2cache | l3cache | socket | numa | board]
(supported qualifiers: overload-allowed,if-supported)
MCA hwloc: parameter "hwloc_base_bind_to_core" (current value: "false", data
source: default, level: 9 dev/all, type: bool)
Bind processes to cores
Valid values: 0: f|false|disabled, 1: t|true|enabled
MCA hwloc: parameter "hwloc_base_bind_to_socket" (current value: "false", data
source: default, level: 9 dev/all, type: bool)
Bind processes to sockets
Valid values: 0: f|false|disabled, 1: t|true|enabled
So clearly it is not activated.
I've tried to set these options to ./configure but it doesn't help:
--enable-mca-direct=hwloc_base_bind_to_core,hwloc_base_bind_to_socket
I know it should work because it is working out of the box with OpenMPI-1.6.3
that I have compiled several months ago.
I think I've messed something but where ?
Thanks for your advices
Patrick
