- * 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

- * 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.

- * follows:
- * @code
- * MyoiUserParams UserParas[64];
- * UserParas[0].type = MYOI_USERPARAMS_DEVID;

- *

- * library is completely initialized on all peers. An example follows,
- * showing how to cause MYO to execute the registered function named
- * "PostMyoLibInitFunction" on the first card only:
- * @code
- * MyoiUserParams UserParas[64];
- * UserParas[0].type = MYOI_USERPARAMS_POST_MYO_LIB_INIT_FUNC;

- * Note, to cause PostMyoLibInitFunction to be executed on ALL cards,
