Hi,
I try to bind both the memory and processes on our compute cluster nodes
but only the processes binding works. How can I also specify to allocate
the memory on the same numa node than where the process is bind? I tried
with the option "--mca hwloc_base_mem_alloc_policy local_only" without
any luck.
I tested the memory biding with a small c++ program that allocates an
array of 1.8GB of memory and then touches that memory. When I run it
with this command line
mpirun -np 8 --mca mpi_paffinity_alone 1 --mca
hwloc_base_mem_alloc_policy local_only ./numa_test
and look at the binding with hwloc-ps or lstopo I get the right
processes binding. However, the /proc/process_id/num_maps doesn't
indicate any memory binding other than the default one and some memory
pages are allocated on both numa node memory.
------cat /proc/process_id/numa_maps ------
...
7fe12d778000 default anon=267996 dirty=267996 active=254510 N0=74502
N1=193494
...
-----
If I run the program again with an explicit hwloc-bind command like this
mpirun -np 4 hwloc-bind --cpubind node:0 --membind node:0 --strict
./numa_test : -np 4 hwloc-bind --cpubind node:1 --membind node:1
--strict ./numa_test
now I get the expected results (with the bind:0 or bind:1),
------cat /proc/process_id/numa_maps ------
...
7fb54cbe4000 bind:0 anon=95747 dirty=95747 active=70221 N0=95747
...
or
...
7fe6e19e3000 bind:1 anon=468751 dirty=468751 N1=468751
...
-----
The comment for the hwloc_base_mem_alloc_policy parameter says:
-------
> MCA hwloc: parameter "hwloc_base_mem_alloc_policy" (current value:
> <none>, data source: default value)
> Policy that determines how general memory
> allocations are bound after MPI_INIT. A value of "none" means that no
> memory policy is applied. A value of "local_only" means that all
> memory allocations will be restricted to the local NUMA node where
> each process is placed. Note that operating system paging policies
> are unaffected by this setting. For example, if "local_only" is used
> and local NUMA node memory is exhausted, a new memory allocation may
> cause paging.
------
I though that it's what I want but it doesn't have any effect.
I compiled Open MPI with these options. I disabled the "first_use"
memory affinity to be sure that openmpi uses the "hwloc" policy (Open
MPI shows the same behavior with or without the "first_use" policy anyway).

Specifies where the default error output
stream goes (this is separate from distinct help messages). Accepts a
comma-delimited
list of: stderr, stdout, syslog,
syslogpri:<notice|info|debug>, syslogid:<str> (where str is the prefix
string for all syslog
notices), file[:filename] (if filename is not
specified, a default filename is used), fileappend (if not specified,
the file is
opened for truncation), level[:N] (if
specified, integer verbose level; otherwise, 0 is implied)
MCA mpi: parameter "mpi_paffinity_alone" (current
value: <0>, data source: default value, synonym of: opal_paffinity_alone)
If nonzero, assume that this job is the only
(set of) process(es) running on each node and bind processes to
processors, starting
with processor ID 0
MCA mpi: parameter "mpi_param_check" (current value:
<1>, data source: default value)
Whether you want MPI API parameters checked at
run-time or not. Possible values are 0 (no checking) and 1 (perform
checking at
run-time)
MCA mpi: parameter "mpi_yield_when_idle" (current
value: <-1>, data source: default value)
Yield the processor when waiting for MPI
communication (for MPI processes, will default to 1 when oversubscribing
nodes)
MCA mpi: parameter "mpi_event_tick_rate" (current
value: <-1>, data source: default value)
How often to progress TCP communications (0 =
never, otherwise specified in microseconds)

Whether MPI_FINALIZE shows all MPI handles
that were not freed or not
MCA mpi: parameter "mpi_no_free_handles" (current
value: <0>, data source: default value)
Whether to actually free MPI objects when
their handles are freed
MCA mpi: parameter "mpi_show_mpi_alloc_mem_leaks"
(current value: <0>, data source: default value)
If >0, MPI_FINALIZE will show up to this many
instances of memory allocated by MPI_ALLOC_MEM that was not freed by
MPI_FREE_MEM
MCA mpi: parameter "mpi_show_mca_params" (current
value: <none>, data source: default value)
Whether to show all MCA parameter values
during MPI_INIT or not (good for reproducability of MPI jobs for debug
purposes).
Accepted values are all, default, file, api,
and enviro - or a comma delimited combination of them
MCA mpi: parameter "mpi_show_mca_params_file" (current
value: <none>, data source: default value)
If mpi_show_mca_params is true, setting this
string to a valid filename tells Open MPI to dump all the MCA parameter
values into
a file suitable for reading via the
mca_param_files parameter (good for reproducability of MPI jobs)
MCA mpi: parameter "mpi_keep_peer_hostnames" (current
value: <1>, data source: default value)
If nonzero, save the string hostnames of all
MPI peer processes (mostly for error / debugging output messages). This
can add
quite a bit of memory usage to each MPI process.
MCA mpi: parameter "mpi_abort_delay" (current value:
<0>, data source: default value)
If nonzero, print out an identifying message
when MPI_ABORT is invoked (hostname, PID of the process that called
MPI_ABORT) and
delay for that many seconds before exiting (a
negative delay value means to never abort). This allows attaching of a
debugger
before quitting the job.
MCA mpi: parameter "mpi_abort_print_stack" (current
value: <0>, data source: default value)
If nonzero, print out a stack trace when
MPI_ABORT is invoked
MCA mpi: parameter "mpi_preconnect_mpi" (current value:
<0>, data source: default value, synonyms: mpi_preconnect_all)
Whether to force MPI processes to fully
wire-up the MPI connections between MPI processes during MPI_INIT (vs.
making connections
lazily -- upon the first MPI traffic between
each process peer pair)
MCA mpi: parameter "mpi_preconnect_all" (current value:
<0>, data source: default value, deprecated, synonym of: mpi_preconnect_mpi)
Whether to force MPI processes to fully
wire-up the MPI connections between MPI processes during MPI_INIT (vs.
making connections
lazily -- upon the first MPI traffic between
each process peer pair)
MCA mpi: parameter "mpi_leave_pinned" (current value:
<-1>, data source: default value)
Whether to use the "leave pinned" protocol or
not. Enabling this setting can help bandwidth performance when
repeatedly sending
and receiving large messages with the same
buffers over RDMA-based networks (0 = do not use "leave pinned"
protocol, 1 = use
"leave pinned" protocol, -1 = allow network to
choose at runtime).
MCA mpi: parameter "mpi_leave_pinned_pipeline" (current
value: <0>, data source: default value)
Whether to use the "leave pinned pipeline"
protocol or not.
MCA mpi: parameter "mpi_warn_on_fork" (current value:
<1>, data source: default value)
If nonzero, issue a warning if program forks
under conditions that could cause system errors
MCA mpi: information "mpi_have_sparse_group_storage"
(value: <0>, data source: default value)
Whether this Open MPI installation supports
storing of data in MPI groups in "sparse" formats (good for extremely
large process
count MPI jobs that create many
communicators/groups)
MCA mpi: parameter "mpi_use_sparse_group_storage"
(current value: <0>, data source: default value)
Whether to use "sparse" storage formats for
MPI groups (only relevant if mpi_have_sparse_group_storage is 1)
MCA mpi: parameter "mpi_notify_init_finalize" (current
value: <1>, data source: default value)
If nonzero, send two notifications during
MPI_INIT: one near when MPI_INIT starts, and another right before
MPI_INIT finishes,
and send 2 notifications during MPI_FINALIZE:
one right when MPI_FINALIZE starts, and another near when MPI_FINALIZE
finishes.
MCA orte: parameter "orte_base_help_aggregate" (current
value: <1>, data source: default value)
If orte_base_help_aggregate is true, duplicate
help messages will be aggregated rather than displayed individually.
This can be
helpful for parallel jobs that experience
multiple identical failures; rather than print out the same help/failure
message N
times, display it once with a count of how
many processes sent the same message.
MCA orte: parameter "orte_tmpdir_base" (current value:
<none>, data source: default value)
Base of the session directory tree
MCA orte: parameter "orte_no_session_dirs" (current
value: <none>, data source: default value)
Prohibited locations for session directories
(multiple locations separated by ',', default=NULL)
MCA orte: parameter "orte_send_profile" (current value:
<0>, data source: default value)
Send profile info in launch message
MCA orte: parameter "orte_debug" (current value: <0>,
data source: default value)
Top-level ORTE debug switch (default verbosity: 1)
MCA orte: parameter "orte_debug_verbose" (current value:
<-1>, data source: default value)
Verbosity level for ORTE debug messages
(default: 1)
MCA orte: parameter "orte_debug_daemons" (current value:
<0>, data source: default value)
Whether to debug the ORTE daemons or not
MCA orte: parameter "orte_debug_daemons_file" (current
value: <0>, data source: default value)
Whether want stdout/stderr of daemons to go to
a file or not
MCA orte: parameter "orte_daemon_bootstrap" (current
value: <0>, data source: default value)
Bootstrap the connection to the HNP
MCA orte: parameter "orte_leave_session_attached"
(current value: <0>, data source: default value)
Whether applications and/or daemons should
leave their sessions attached so that any output can be received - this
allows X
forwarding without all the attendant debugging
output
MCA orte: parameter "orte_output_debugger_proctable"
(current value: <0>, data source: default value)
Whether or not to output the debugger
proctable after launch (default: false)
MCA orte: parameter "orte_debugger_test_daemon" (current
value: <none>, data source: default value)
Name of the executable to be used to simulate
a debugger colaunch (relative or absolute path)
MCA orte: parameter "orte_debugger_test_attach" (current
value: <0>, data source: default value)
Test debugger colaunch after debugger attachment
MCA orte: parameter "orte_debugger_check_rate" (current
value: <0>, data source: default value)
Set rate (in secs) for auto-detect of debugger
attachment (0 => do not check)
MCA orte: parameter "orte_do_not_launch" (current value:
<0>, data source: default value)

value: <0>, data source: default value)
Seconds between checks for daemon
state-of-health (default: 0 => do not check)
