These platform files were created from platform files shipped with the release
tarball. Each file has been modified. Here are the details on how they were
created.
- common
Copy of contrib/platform/lanl/toss/toss-common. Removed entries in bottom
half of file that were specific to TOSS so that it could be used for Cray
platforms as well.
- common-optimized
Copy of contrib/platform/lanl/toss/optimized-common. Used the file as-is.
- toss2-qib-optimized
Copy of contrib/platform/lanl/toss/optimized with the following changes:
- source common and common-optimzed instead of toss-common and
optimized-common
- added entries that were removed from common:
- enable_mca_no_build
- with_slurm
- with_tm
- with_pmi
- with_verbs
- NOTE: common had "with_devel_headers=yes" in it that was not propagated.
This option should not be used in production as per Open MPI developer
mailing list guidance.
- Changed comment "Disable components not needed on any TOSS platform" to
"Disable components not needed on TOSS platforms with high-speed networks"
- Changed "enable panasas" to "enable lustre"
- toss2-qib-optimized.conf
- copy of contrib/platform/lanl/toss/optimized.conf with the following
changes:
- changed: orte_no_session_dirs = /lustre,/net,/users,/usr/projects
- changed: btl = ^openib
- removed: hwloc_base_binding_policy = core (outdated setting)
- added: rmaps_base_ranking_policy = core (rank by core)
- added: ras_base_launch_orted_on_hn = true (run orted on parent node of
allocation)
- toss2-mlx-optimized
- copy of toss2-qib-optimized
- toss2-mlx-optimized.conf
- copy of toss2-qib-optimized.conf with the following changes:
- remove: oob_tcp_if_include = ib0,eth0 (identification of general network
device names is problematic in RHEL7. Just let Open MPI figure it out)
- change: btl = vader,openib,self
- change: btl_openib_receive_queues = X,4096,1024:X,12288,512:X,65536,512
(change S to X; make sure numbers match those for the same entry in
contrib/platform/lanl/toss/optimized-mlx.conf)
- addition: pml = ob1 (disable MXM)
- addition: coll = ^hcoll (disable MXM)
- toss3-hfi-optimized
- copy of toss2-qib-optimized
- toss3-hfi-optimized.conf
- copy of toss2-qib-optimized.conf with the following changes:
- remove: oob_tcp_if_include = ib0,eth0
- add: oob_tcp_if_exclude = ib0 (Omnipath is flaky; don't use it for oob)
- toss3-wc-optimized (platform file for woodchuck which is an ethernet-only
connected cluster)
- copy of toss3-hfi-optimized with the following changes:
- change: remove "btl-tcp" from the enable_mca_no_build list
- change: comment "Disable components not needed on TOSS platforms with
high-speed networks" to "Disable components not needed on TOSS Ethernet-
connected clusters"
- change: with_verbs=no
- change: comment "Always build ibverbs support" to "Do not build ibverbs
support"
- toss3-wc-optimized.conf
- copy of toss3-hfi-optimized.conf with the following changes:
- change: comment "Add the interface for out-of-band communication and set
it up" to "Set up the interface for out-of-band communication"
- remove: oob_tcp_if_exclude = ib0
- remove: btl (let Open MPI figure out what best to use for ethernet-
connected hardware)
- remove: btl_openib_want_fork_support (no infiniband)
- remove: btl_openib_receive_queues (no infiniband)
- cray-lustre-optimized
- copy of contrib/platform/lanl/cray_xc_cle5.2/optimized-lustre with the
following changes:
- remove: whole if/else clause of 'test "$enable_debug" = "yes"'
- addition: source ./common
- addition: source ./common-optimized
- change: with_io_romio_flags="--with-file-system=ufs+nfs+lustre"
- remove: with_lustre=/opt/cray/lustre-cray_ari_s/default
- additions from platform/lanl/cray_xc_cle5.2/optimized-common that don't
go in common-optimzed:
- enable_mca_no_build=crs,filem,routed-linear,snapc,pml-dr,pml-crcp2,pml-crcpw,pml-v,pml-example,crcp,pml-cm,ess-cnos,grpcomm-cnos,plm-rsh,btl-tcp,oob-ud,ras-simulator,mpool-fake
- enable_mca_static=btl:ugni,btl:self,btl:vader,pml:ob1
- enable_mca_directpml-ob1
- with_verbs=no
- with_tm=no
- enable_orte_static_ports=no
- enable_pty_support=no
- addition: enable_dlopen=yes (change from original platform file as per
Nathan Hjelm)
- cray-lustre-optimized.conf
- copy of contrib/platform/lanl/cray_xc_cle5.2/optimized-lustre.conf with
the following changes:
- change: orte_no_session_dirs = /lustre,/users,/usr/projects
- remove: hwloc_base_binding_policy = core (outdated setting)
- addition: rmaps_base_ranking_policy = core (rank by core)
