# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

/// words, this memory is not available for use until it is freed up.
/// 3. Unexpected segmentation faults or erroneous behaviour can occur if

/// For example, if a variable passed in as Misc data or the buffer gets
/// destroyed before the Intel® Coprocessor Offload Infrastructure (Intel® COI) runtime receives the completion notification

Arena-based APIs

/*
* Arena is a set of memory pages with the same ownership type. The ownership
* type of all the memory pages inside the same arena can only be changed as
* a whole. For "OURS", it is also the minimal unit of sync operations to
* implement "release consistency".
*/
/** @fn extern MyoError myoArenaCreate(MyoOwnershipType in_Type,
* int in_Property, MyoArena *out_pArena)
* @brief Create an arena with specified ownership type and property.
*
* @param in_Type Specified ownership type (MYO_ARENA_OURS or
* MYO_ARENA_MINE).
* @param in_Property Specified properties of the arena. Set it
* to 0 to use default properties.
*
* MYO_RELEASE_CONSISTENCY or MYO_STRONG_RELEASE_CONSISTENCY
* or MYO_STRONG_CONSISTENCY:
*
* Consistency modes for "OURS" arenas. For MYO_RELEASE_CONSISTENCY,
* there are 2 functions, "Acquire" and "Release", which are
* used for memory ordering. "Release" makes all local stores
* prior to the release globally visible; "Acquire" syncs up the
* local memory with all stores that have been made globally
* visible. However, there is no definite answer as to whether
* local stores can be globally visible before reaching a release
* point, nor whether the newest globally visible stores can be
* updated to local before reaching an acquire point. By using
* MYO_STRONG_RELEASE_CONSISTENCY, the answer to these questions
* is "no". A sequential consistency model is maintained to the
* arena when using MYO_STRONG_CONSISTENCY.
* MYO_RELEASE_CONSISTENCY is the default property.
*
* MYO_UPDATE_ON_DEMAND or MYO_UPDATE_ON_ACQUIRE:
*
* Only apply to "OURS" arenas with "Release Consistency".
* MYO_UPDATE_ON_ACQUIRE means that the shared pages of this
* arena will be updated on acquire point; MYO_UPDATE_ON_DEMAND
* means that the shared pages will not be updated until they
* are accessed. MYO_UPDATE_ON_DEMAND is the default property.
*
* MYO_RECORD_DIRTY or MYO_NOT_RECORD_DIRTY:
*
* This property controls whether to record dirty pages.
* There will be runtime overhead when recording dirty pages,
* as it can reduce the communication data. It is a trade-off
* for performance. Also when MYO_NOT_RECORD_DIRTY is set for
* "OURS" arena, the runtime cannot guarantee the correctness
* when the host and card modify the same shared page between
* the same sync segment. MYO_RECORD_DIRTY is the default
* property.
*
* MYO_ONE_VERSION or MYO_MULTI_VERSION:
*
* Only apply to "OURS" arenas with "Release Consistency". When
* MYO_MULTI_VERSION is set, this arena can only be "release" on
* HOST side and "acquire" on CARD side. Releasing the arena on
* HOST will create a new versioned data and put it into a FIFO;
* acquiring the arena on CARD will get the versioned data
* from the FIFO one by one. MYO_ONE_VERSION is the default
* property.
*
* MYO_CONSISTENCY or MYO_NO_CONSISTENCY:
*
* Only apply to "OURS" arenas with "Release Consistency". When
* MYO_NO_CONSISTENCY is set, the consistency of the arena will
* not be maintained. That is, it is a no-op operation when
* calling acquire/release for such arenas. MYO_CONSISTENCY is
* the default property.
*
* MYO_HOST_TO_DEVICE and MYO_DEVICE_TO_HOST:
*
* When it is certain that there is only one communication
* direction for this arena, it can be created with only
* MYO_HOST_TO_DEVICE or MYO_DEVICE_TO_HOST so the runtime
* can perform optimizations. The default property is
* MYO_HOST_TO_DEVICE | MYO_DEVICE_TO_HOST.

* It is Compiler's responsibility to make sure all shared variables

* However, it is hard for Compiler to do this. So we propose a solution
* which is changing the definition of all shared variables and accessing
* them indirectly, and making sure all shared variables pointing
* to the same shared space on all sides. For example,
*
* "shared int a;" is changed to "shared int *a";
* Also all the accesses to "a" is change to "*a".
*
* We suppose the shared memory for each shared variable is allocated on
* host side by Compiler. For the upper example, Compiler can call:
*
* a = (shared int *) myoSharedMalloc(sizeof(shared int));
*
* Now the issue is how to make "a" on other sides also pointing to the
* same shared memory on other sides. We provide two methods to do this.
* They can be used in a hybrid way.
*/
/*
* The first method is calling myoiVarRegister for each shared variable
* on all sides in myoiUserInit. On host side, we will get a table containing
* a table containing the shared address and name of each shared variable.
* After calling myoiUserInit, we will propagate the table to other sides.
* On card side, after getting the table from host, myoiUserInit is called.
* When calling myoiVarRegister in myoiUserInit, we will make local pointer
* of each shared variable pointing to the same shared memory with the local
* pointer on host side of the same shared variable pointing to.

* On host side, the table contains the name and the shared address of each
* shared variable. On card side, the table contains the name of each shared
* variable and the address of the local pointer which will pointing to shared
* memory space.
*
* On host side, Compiler generates a call to myoiHostVarTablePropagate
* after initializing MYO runtime and making the host side table ready.
* On card side, Compiler uses myoiMicVarTableRegister to tell
* the runtime where the card side table is.
*
* Since there may be multiple libraries on card side for the same application,
