2 years agoCode-format: separated user/ghost global obj init. master
Min Si [Tue, 16 Aug 2016 23:25:57 +0000]
Code-format: separated user/ghost global obj init.

Separate global objects (members in CSP_PROC) into three parts:
- common information (e.g., wrank, node_id)
- user-specific information (e.g., ghost ranks, user communicators)
- ghost-specific information (i.e., ghost local communicator)

Because communicators have to be collectively created, all communicators
are initialized in common routine CSP_initialize_proc.

To determine whether I am user or ghost, always call CSP_IS_USER or

2 years agoAlways set false noncontig in internal win_allocate_shared.
Min Si [Mon, 15 Aug 2016 16:09:03 +0000]
Always set false noncontig in internal win_allocate_shared.

To support noncontig hint, we need to modify the internal shared window
creation in win_allocate: (1) allowing arbitrary order of segments in
offset calculation; (2) using win_create_dynamic instead of win_create,
to attach multiple segments on ghosts. Moreover, we need to optimize
win_create_dynamic in MPI implementation similar as that for win_create.

The above work is planed as a future work. For now, the Casper library

2 years agoBug-fix: use addr of first non-zero segment in win_alloc.
Min Si [Thu, 11 Aug 2016 22:07:31 +0000]
Bug-fix: use addr of first non-zero segment in win_alloc.

In win_allocate, we internally use win_allocate_shared + win_create,
where ghost processes pass zero-size in win_allocate_shared and user
processes just pass what user specified. To enable access to local user
processes' window segments, we need to pass the start address of entire
shared memory buffer per node at ghosts' win_create call.

The previous code used first local process (a ghost)'s base address as
the base in win_create. This can be wrong if MPI implementation returns
NULL pointer for process with zero-size segment (e.g., we get this error
with MPICH-CH4). This patch fixes the issue by using the address of the
first non-zero segment on that node.

deal with MPIR_Win_flavor_t the right way

MPIR_Win_flavor_t is MPICH-specific and should instead
be an int, which is the type of window flavors in the
MPI standard.  as MPIR_Win_flavor_t is an enum, the

Perf-test-fix: use appropriate epoch to reset window.

Some performance tests specify particular epoch_type info (e.g.,
lockall, fence) to avoid unnecessary overhead. However, these tests used

3 years agoImplemented exclusive lock routine for ghost commands.
Min Si [Tue, 18 Aug 2015 22:56:40 +0000]
Implemented exclusive lock routine for ghost commands.

Two user groups may concurrently require the same ghost process to
handle its function command. For example, group(0, 2) and group(1, 3)
may allocate window concurrently, while user 0, 1 are sharing G0, and
user 2, 3 are sharing G1. The previous code does not handle this case,
resulting in dead lock.

In this patch, we implemented a lock mechanism to provide exclusive
accessing to multiple ghost processes for user function commands (i.e.,
win_allocate, win_free).
- The first user process on every node (user root) collectively locks
  its first local ghost process;
- When two groups concurrently acquire lock on the same ghost, we decide
  ordering of lock by priority (every group has unique group_id, the
smaller group_id the higher priority);
- Low priority group always give up its lock if any high priority group
  is waiting.
- Function command will be issued to ghosts only when every user root
  has acquired the lock.
- Lock is released by ghost after function finished on ghost side.

Bug-fix: get ghost ranks in user-ghost communicator.

Previous code incorrectly used ranks in comm world as the unique ghost

Min Si [Sun, 16 Aug 2015 21:05:53 +0000]
Renamed active_win to global_win.

Previous code used "active_win" as the variable name of the global
window. However, this window is used by all active epochs and also
lockall epoch in no-lock mode. This patch renamed it to "global_win",
since it is not only for active epochs.

In previous code, generic processing (i.e., flush on global window used
by fence, complete, and flush_all in no-lock mode) was duplicately

The previous code still created a separate window for no-lock mode
(i.e., in fence|lock_all mode, two windows are created), which is not
necessary. This patch changed it, now if no-lock mode is specified, only
one global active_win will be created, and lock_all/unlock_all on this
window will only be executed once in win_allocate/win_free respectively.

- The user side issues a command by sending its corresponding packet to
  the local ghost root;
- On ghost side, every received command is handled by its corresponding
  handler function;
- Define fixed length parameters in each packet structure,
  variable-length parameters or data that cannot be got at command

Ghost processes must wait till all local processes arrived finalize
before they start finalize. However, in the previous code, only the
local user root issues finalize command to ghosts, and ghosts start
finalize just when received that command. This is wrong, because other
local processes may issue other command (i.e., win_allocate) later than
the finalize command issued by local user root, thus those commands can
not be handled by ghosts, consequently user processes hang. This patch
fixed it.

In current version, ghost process starts finalize just when received
finalize command from the first local process. This is not correct
because the other processes may hang if they issue command like
win_allocate later than finalize command issued by the first local

Min Si [Fri, 10 Jul 2015 04:07:35 +0000]
Disabled hidden byte for local lock and removed ghost segment.

This patch includes two changes:
1. disable hidden byte for force local lock.
2. removed additional segment on every ghost since 0-size win_shared has
been fixed in MPI (need to revert it if work with an MPI implementation
still having the bug).

4 years agoSet name for comm_user_world.
Min Si [Thu, 2 Jul 2015 16:30:55 +0000]
Set name for comm_user_world.

Since its name must be MPI_COMM_WORLD for user program, we set its name
at init time.

4 years agoImplemented Win_get_attr to override win_create flavor.
Min Si [Mon, 29 Jun 2015 19:24:53 +0000]
Implemented Win_get_attr to override win_create flavor.

MPI defines several window attributes (i.e., MPI_WIN_BASE,
MPI_WIN_CREATE_FLAVOR). User can call win_get_attr to query their
value. Only the win_create flavor is changed within Casper, since user
window is internally created by WIN_CREATE but not WIN_ALLOCATE. Thus we
override the win_get_attr function and return a "fake" win_create
flavor to user. For all other attributes, we just call the original

4 years agoAdded eager pscw sync option.
Min Si [Mon, 29 Jun 2015 18:16:33 +0000]
Added eager pscw sync option.

If eager-pscw-sync is enabled, the receive calls for cw-sync will be
issued in post right after ps-sync.

4 years agoImplemented Win_test.
Min Si [Mon, 29 Jun 2015 18:16:06 +0000]
Implemented Win_test.

This patch implemented Win_test with following changes:
(1) The first test/wait call issues receive and stores requests for
later waitall/testall. The first complete test/wait frees such requests
(2) Added exposure epoch status check to avoid the following case:
- first test(issue receive, then all requests are complete and freed)
- second test (assume it is the first test since requests is NULL, thus
issue receive again)

4 years agoFixed minor compiling error in runtime-load-enabled mode.

Min Si [Fri, 26 Jun 2015 18:45:39 +0000]
Added verbose env flag and runtime-load, epoch check config.

This patch adds several user-friendly options:
(1) Added a environment variable CSP_VERBOSE to enable configuration
(2) Added following config options to enable runtime load balancing
optimization, and disable epoch status check respectively.
--enable-runtime-load (disabled by default)
--disable-epochstat-check (enabled by default)

4 years agoImplemented remaining RMA operations.
Min Si [Mon, 22 Jun 2015 21:42:21 +0000]

4 years agoRewrote access epoch status routine.
Min Si [Mon, 22 Jun 2015 22:20:32 +0000]
Rewrote access epoch status routine.

This patch includes three parts related to access epoch status:
(1) Manage pscw and lock epoch per target, lockall and fence
(2) Get window for every operation according to both per-target
status and global status.
(3) Added epoch status check in sync calls of access epochs. This
check can be enabled/disabled by CSP_ENABLE_EPOCH_STAT_CHECK.

4 years agoAdded MPI_PROC_NULL for operations/per-target sync calls.
Min Si [Sun, 21 Jun 2015 19:10:16 +0000]
Added MPI_PROC_NULL for operations/per-target sync calls.

4 years agoChanged to support user specified mpi path.
Min Si [Wed, 17 Jun 2015 16:27:44 +0000]
Changed to support user specified mpi path. checks mpi.h in three steps:
(1) Get a default path by checking `which mpicc` (may be undefined)
(2) If user specifies <path>, check <path>/include/mpi.h. If found, use
it to generate wrapper functions, otherwise exit error.
(3) If user does not specify, check default path. If found, use it
otherwise exit error.
