\frametitle{Les Types de données abstraits}
|
||||
|
||||
Pour communiquer entre eux, les processus doivent utiliser des objets partagés. \\
|
||||
|
||||
Pour spécifier la notion d'objets partagés nous allons d'abord cerner la notion de type de donnée abstrait :
|
||||
\begin{block}{Définition}
|
||||
Un type de donnée abstrait peut être défini par un automate tel que : $T = (A, B, Z, \zeta_0, \tau, \delta)$ \\
|
||||
Tel que :
|
||||
\begin{itemize}
|
||||
\item A est un ensemble dénombrable (alphabet d'entrée)
|
||||
\item B est un ensemble dénombrable (alphabet de sortie)
|
||||
\item Z est un ensemble dénombrable d'états abstraits
|
||||
\item $\zeta_0 \in Z$ est l'état initial
|
||||
\item $\tau$ est la fonction de transition ($Z \times A \rightarrow Z$)
|
||||
\item $\delta$ est la fonction de sortie ($Z \times A \rightarrow B$)
|
||||
\end{itemize}
|
||||

# Script présentation Cohérence Faible
|
||||
|
||||
## Plan
|
||||
|
||||
1. Présenter un processus séquentiel classique
|
||||
- exemple : processeur monocœur
|
||||
2. Introduire le concept de cohérence via la cohérence forte (le plus intuitif)
|
||||
- exemple : processeur multicœur, application distribuée centralisée.
|
||||
- notions : respect de l'ordre, atomicité, isolation
|
||||
3. Introduire le concept de cohérence faible
|
||||
- exemple : application distribuée décentralisée
|
||||
4. Définir les propriétés d'un système réparti
|
||||
5. Définir les différents modèles de cohérence faible (des plus trivial aux moins)
|
||||
1. Cohérence Séquentielle (SC)
|
||||
2. Linéarisabilité -> Serialisabilité
|
||||
3. Convergence/Convergence Forte
|
||||
1. Définit le concept de convergence
|
||||
2. Pourquoi ? + les apports de la convergence forte
|
||||
3. Types de données basés sur la convergence (pourquoi ?)
|
||||
4. Cohérence Pipeline
|
||||
1. On présente la notion d'Intention
|
||||
2. On l'oppose à la cohérence Pipeline
|
||||
|
||||
6. Cohérence d'écriture
|
||||
1. Ce que ne couvre pas les modèles précédents
|
||||
2. Cohérence d'écriture et cohérence d'écriture forte.

Un ensemble d'événement est dit linéarisable s'il existe une séquence d'événement qui respecte les 3 propriétés suivantes :

Une approche pour définir la cohérence d'un algorithme est de placer l'histoire concurrente qu'il produit dans une classe de cohérence. \\

|

\item \textbf{Omitting Dependencies} : Création d'une opération suivant un sous ensemble des dépendances réelles.
|
||||
\item \textbf{Unseen Dependencies} : Anticipation d'une opération non reçue par le système, mais probable d'arrivée.
|
||||
\item \textbf{Sibling Generation} : Création de deux opérations différentes possédant le même identifiant. Réalisant ainsi une divergence entre les nœuds.

\begin{itemize}

\item \textbf{Immutable History} : Chaque opération est envoyée avec son passé causal. (Parade le \textbf{Tempering})
|
||||
\item \textbf{No Future Dependencies} : Chaque opération est envoyée avec l'état qu'il connait des nœuds. (Parade l'\textbf{Unseen Dependencies}, il devient impossible de créer une opération à l'avance).
|
||||
\item \textbf{Causal Execution} : Toute opération $o_i$ appartenant au passé causal d'une opération $o$ doit être sérialisable t.q. : $o_i < o$. (Fait office de synchronisation entre les nœuds)
|
||||
\item \textbf{Eventual Sibling Detection} : Les opérations sont considérées comme des "jumeaux" éventuels et sont donc "révocables" via une nouvelle opération dédiée. (Parade (relativement) le \textbf{Sibling Generation})

\item \textbf{Limited Omission} : à travailler

# "Event Horizon": Lot 2 21/06/2023
|
||||
### JOLY Amaury (Laboratoire d'Informatique et Système, Parsec)
|
||||
### __Encadrants:__ Emmanuel GODARD, Corentin TRAVERS (Equipe Algorithmique Distribuée)

# Rappel des objectifs
|
||||
|
||||
--
|
||||
|
||||
## Pour Parsec
|
||||
|
||||
__Lot 2 :__ Ajout à Parsec d'un outil d'édition collaborative.
|
||||
|
||||
Dans approche visant à maximiser les performances (latence et interactivité) et la résilience.
|
||||
|
||||
--
|
||||
|
||||
## Pour le LIS
|
||||
|
||||
Produire de la recherche sur la cohérence faible en milieu byzantin.
|
||||
|
||||
--
|
||||
|
||||
## La synthèse des deux
|
||||
|
||||
1. Faire un état de l'art des solutions existantes.
|
||||
- Prendre des décisions sur les choix techniques à adopter.
|
||||
2. Recherche d'un compromis algorithmique __résilience__/__intéractivité__.
|
||||
3. Réaliser un produit innovant dans sa gestion de la cohérence.
|
||||
- Chercher une valeur ajoutée pour l'utilisateur.

## Quelques définitions

__Systèmes répartis :__
|

## Quelques définitions
|
||||
|
||||
__Cohérence dans un système reparti:__
|
||||
Étude du comportement des données dans un système reparti d'un point de vue observateur.
|
||||
|
||||
__Cohérence forte :__
|
||||
Comportement attendu dans le cas d'une exécution à un seul acteur.

## État de l'art
|
||||
|
||||
- Cohérence dans les systèmes répartis.
|

- Lamports (1970)
|

- Perrin : Concurrence et Cohérence des Systèmes répartis (2017)

## État de l'art

|
||||
### Un (très) rapide résumé
|
||||
|
||||
<img src="./img/cartographie_simplifie.png" alt="cartographie des critères de cohérences" height="250"/>
|
||||
|
||||
- Les critères de cohérences s'articulent autour de 3 propriétés élémentaires.
|
||||
- La conjonction des 3 représente le comportement d'un programme séquentiel.
|
||||
- Nous cherchons un compromis pour maximiser l'interactivité du produit
|
||||
|
||||
|
||||
--
|
||||
|
||||
## État de l'art
|
||||
|
||||
### Un (très) rapide résumé
|
||||
|
||||
- Inventaire des différentes solutions existantes.
|
||||
- Peu de littérature.
|
||||
- Pas de taxonomie consensuelle, travail de classification
|
||||
|
||||
- Peu de réflexions sur les potentiels fautes byzantines induites par la (les ?) cohérences faibles.

# La suite
|
||||
|
||||
--
|
||||
|
||||
## La liste des tâches
|
||||
|
||||
- [ ] Réaliser l'état de l'art
|
||||
- [x] Gestion de la cohérence dans les systèmes répartis.
|
||||
- [ ] Faire l'inventaire des solutions existantes. (BFT weak consistency).
|
||||
- [x] Lister les solutions algorithmiques dans la littérature.
|
||||
- [ ] S'intéresser aux solutions open-source (e.g.: etherpad)
|
||||
- [ ] Classer les solutions.
|
||||
- [ ] Produire/adapter un algorithme dans une situation de référence (à déterminer).
|
||||
- [ ] Formaliser les besoins du produit.
|
||||
- [ ] Essayer de les satisfaire.
|
||||
- [ ] Réaliser un PoC.
|
||||
|
||||
|
||||
--
|
||||
|
||||
## Pour les mois à venir
|
||||
|
||||
Je vous propose une réunion en distanciel (~2h) pour :
|
||||
1. Vous présenter l'état de l'art.
|
||||
2. Placer le produit suivant ces contraintes.

/**

[ sunblind ]
|
||||
|
||||
A blindingly sunny theme for Reveal.js with Lora + Leto fonts and a colorful border.
|
||||
By Josh Dzielak, https://dzello.com/, License MIT
|
||||
|
||||
The bold border is optional and requires some HTML. To use it:
|
||||
|
||||
1. Add 4 divs to your HTML page:
|
||||
<div class="line top"></div>
|
||||
<div class="line bottom"></div>
|
||||
<div class="line left"></div>
|
||||
<div class="line right"></div>
|
||||
|
||||
2. Set { margin: 0.2 } in the Reveal.js initializer to make sure
|
||||
your presentation content doesn't collide with the frame.
|
||||
|
||||
Like the theme but don't like the colors? Don't fret. Just change
|
||||
$borderColor and/or $linkColor below to something else and rebuild.
|
||||
|
||||
Or if you don't want to rebuild the theme just override the .line background
|
||||
property with some CSS:
|
||||
|
||||
.line {
|
||||
background: <new-color>;
|
||||
}
|
||||

||||
