allGather
virtual Request	allGather (ConstArrayView< char > send_buf, ArrayView< char > recv_buf)=0
	Effectue un regroupement sur tous les processeurs. Il s'agit d'une opération collective. Le tableau send_buf doit avoir la même taille, notée n, pour tous les processeurs et le tableau recv_buf doit avoir une taille égale au nombre de processeurs multiplié par n.

opérations de broadcast
Envoie un tableau de valeurs sur tous les sous-domaines. Cette opération envoie le tableau de valeur send_buf sur tous les sous-domaines. Le tableau utilisé est celui dont le rang (commRank) est rank. Tous les sous-domaines participants doivent appelés cette méthode avec le même paramètre rank et avoir un tableau send_buf contenant le même nombre d'éléments.

Documentation des fonctions membres

allToAll()

virtual Request Arcane::IParallelNonBlockingCollective::allToAll ( ConstArrayView< char >  send_buf, ArrayView< char >  recv_buf, Integer  count  )

pure virtual

Effectue un broadcast d'une zone mémoire.

Le processeur qui effectue le broacast est donnée par \id. Le tableau envoyé est alors donnée par bytes. Les processeurs réceptionnent le tableau dans bytes. Ce tableau est alloué automatiquement, les processeurs réceptionnant n'ont pas besoin de connaitre le nombre d'octets devant être envoyés.

barrier()

virtual Request Arcane::IParallelNonBlockingCollective::barrier ( )

pure virtual

Effectue une barière.

Implémenté dans Arcane::MpiParallelNonBlockingCollective.

build()

virtual void Arcane::IParallelNonBlockingCollective::build ( )

pure virtual

Construit l'instance.

Implémenté dans Arcane::MpiParallelNonBlockingCollective.

Référencé par Arcane::MpiParallelMng::build().

hasValidReduceForDerivedType()

virtual bool Arcane::IParallelNonBlockingCollective::hasValidReduceForDerivedType ( ) const

pure virtual

Indique si l'implémentation autorise les réductions sur les types dérivés.

Les version de OpenMPI jusqu'à la version 1.8.4 incluses semblent avoir un bug (qui se traduit par un plantage) avec les réductions non bloquantes lorsque l'opérateur de réduction est redéfini. C'est le cas avec les types dérivés tels que Real3, Real2, ...

Implémenté dans Arcane::MpiParallelNonBlockingCollective.

parallelMng()

virtual IParallelMng * Arcane::IParallelNonBlockingCollective::parallelMng ( ) const

pure virtual

Gestionnaire de parallélisme associé.

Implémenté dans Arcane::ParallelNonBlockingCollectiveDispatcher.
