It provides distributed multi-dimensional NumPy +arrays, distributed ufuncs, and distributed IO capabilities. It can +efficiently interoperate with external distributed libraries like Trilinos. +DistArray works with NumPy and builds on top of it in a flexible and natural +way. + +0.6 Release +----------- + +Noteworthy improvements in this release include: + +* a new website, (http://docs.enthought.com/distarray/), with links to + DistArray talks and presentations, +* redistribution for block-distributed (and non-distributed) DistArrays, +* experimental "quickstart" installation scripts, +* an easier API for ``Context.apply`` +* expanded and improved example notebooks, including a new parallel Gaussian + Elimination example by Prashant Mital, +* compatibility with NumPy 1.9, +* expanded TravisCI testing (OS X and Python 3.5), +* logos by Erick Michaud, and +* several bug-fixes and code improvements. + +Existing features +----------------- + +DistArray + +* supports NumPy-like slicing, reductions, and ufuncs on distributed + multidimensional arrays; +* has a client-engine process design -- data resides on the worker processes, + commands are initiated from master; +* allows full control over what is executed on the worker processes and + integrates transparently with the master process; +* allows direct communication between workers, bypassing the master process + for scalability; +* integrates with IPython.parallel for interactive creation and exploration of + distributed data; +* supports distributed ufuncs (currently without broadcasting); +* builds on and leverages MPI via MPI4Py in a transparent and user-friendly + way; +* has basic support for unstructured arrays; +* supports user-controllable array distributions across workers (block, + cyclic, block-cyclic, and unstructured) on a per-axis basis; +* has a straightforward API to control how an array is distributed; +* has basic plotting support for visualization of array distributions; +* separates the array’s distribution from the array’s data -- useful for + slicing, reductions, redistribution, broadcasting, and other operations; +* implements distributed random arrays; +* supports ``.npy``-like flat-file IO and hdf5 parallel IO (via ``h5py``); + leverages MPI-based IO parallelism in an easy-to-use and transparent way; + and +* supports the distributed array protocol [protocol]_, which allows + independently developed parallel libraries to share distributed arrays + without copying, analogous to the PEP-3118 new buffer protocol. + +Planned features +---------------- + +Planned features include + +* array re-distribution capabilities for more distribution types; +* lazy evaluation and deferred computation for latency hiding; +* examples of interoperation with Trilinos [Trilinos]_; +* distributed broadcasting support. +* integration with other packages [petsc]_ that subscribe to the distributed + array protocol [protocol]_; +* distributed fancy indexing; +* out-of-core computations; +* support for distributed sorting and other non-trivial distributed + algorithms; and +* end-user control over communication and temporary array creation, and other + performance aspects of distributed computations. + +History and funding +------------------- + +Brian Granger started DistArray as a NASA-funded SBIR project in 2008. +Enthought picked it up as part of a DOE Phase II SBIR [SBIR]_ to provide a +generally useful distributed array package. It builds on NumPy, MPI, MPI4Py, +IPython, IPython.parallel, and interfaces with the Trilinos suite of +distributed HPC solvers (via PyTrilinos [Trilinos]_). + +This material is based upon work supported by the Department of Energy under +Award Number DE-SC0007699. + +This report was prepared as an account of work sponsored by an agency of the +United States Government.

+ test ipython notebook nb format 3

+
+ +
+

Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod +tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At +vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, +no sea takimata sanctus est Lorem ipsum dolor sit amet.

+

Loading a notebook nbformat = 3.0

+

+

+
+
+
+
+

Il s’agit de repérer les données nécessaires voire indispensables à la +résolution. Ces données peuvent être:

+
    +
  • numériques,
    • +
  • ou sous forme de textes (on dit souvent chaînes de caractères),
    • +
  • ou de type logique (à deux valeurs possibles, vrai ou faux).
    • +
+

Pour affecter une valeur à une variable en python, la syntaxe est de la forme:

+
nom = valeur
+
+
Affectation
+
Dans un programme, une affectation donne une valeur à une variable, elle est de la forme v = e avec v une variable et e une expression. +
+
+ +

Valeurs numériques

+

Python distingue les entiers(integers), des nombres à +virgule(floating-point) par l'ajout d'une virgule:

+
+
+
+
+
+
In [2]:
+
+
+
a = 1
+b = 1.0
+
+print(a, type(a), b, type(b))
+
+ +
+
+
+ +
+
+ + +
+
+
+1 <class 'int'> 1.0 <class 'float'>
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Mais il implémente aussi des nombres plus exotiques tels que les +décimaux, les fractions ou encore les nombres complexes

+

Chaînes de caractères

+

En python3, il existe deux grands types de chaînes de caractères, les +strings, et les bytes. Les strings sont simplement entourées par des +guillemets simples ou doubles.

+
+
+
+
+
+
In [3]:
+
+
+
a = 'Mon texte'
+b = "Mon deuxième texte"
+
+print(a, type(a), b, type(b))
+
+ +
+
+
+ +
+
+ + +
+
+
+Mon texte <class 'str'> Mon deuxième texte <class 'str'>
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Les bytes sont précédées de la lettre b, il s'agit de texte brut utilisé +par la machine mais pas toujours lisible par un humain.

+
+
+
+
+
+
In [4]:
+
+
+
a = b'Mon texte'
+print(a, type(a))
+
+ +
+
+
+ +
+
+ + +
+
+
+b'Mon texte' <class 'bytes'>
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

On ne peut représenter simplement que certains caractères(les caractères +ASCII), les caractères accentués ne peuvent être écrits directement.

+
+
+
+
+
+
In [5]:
+
+
+
b = b'Mon deuxième texte'
+
+ +
+
+
+ +
+
+ + +
+
+
+  File "<ipython-input-5-b0bf0ef2715d>", line 1
+    b = b'Mon deuxième texte'
+       ^
+SyntaxError: bytes can only contain ASCII literal characters.
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Un encodage autre que le ASCII doit être utilisé pour ces caractères, +comme par exemple le UTF-8 qui est un codage sur huit bits très répandu.

+
+
+
+
+
+
In [6]:
+
+
+
b = b'Mon deuxi\xc3\xa8me texte'
+print(b)
+print(b.decode('utf-8'))
+
+ +
+
+
+ +
+
+ + +
+
+
+b'Mon deuxi\xc3\xa8me texte'
+Mon deuxième texte
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Valeurs logiques

+

On les appelle les booléens, il ne peuvent avoir que deux valeurs:

+
    +
  • VRAI ou FAUX: True ou False en anglais;
    • +
  • 1 ou 0.
    • +
+

On les utilise pour réaliser des tests.

+
+
+
+
+
+
In [7]:
+
+
+
1 < 2, 1 > 2, 2 == 10, 2 >= 1.9, 2 == 2, 2 != 2
+
+ +
+
+
+ +
+
+ + +
Out[7]:
+ + +
+
+(True, False, False, True, True, False)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut aussi les utiliser pour savoir si une variable existe.

+
+
+
+
+
+
In [8]:
+
+
+
bool(a)
+
+ +
+
+
+ +
+
+ + +
Out[8]:
+ + +
+
+True
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut aussi combiner plusieurs tests avec les opérateurs booléens and, or et not.

+
+
+
+
+
+
In [9]:
+
+
+
1 < 2 or 2 < 1
+
+ +
+
+
+ +
+
+ + +
Out[9]:
+ + +
+
+True
+
+
+ +
+ +
+
+ +
+
+
+
In [10]:
+
+
+
1 < 2 and 2 < 1
+
+ +
+
+
+ +
+
+ + +
Out[10]:
+ + +
+
+False
+
+
+ +
+ +
+
+ +
+
+
+
In [11]:
+
+
+
not(1 < 2 and 2 < 1)
+
+ +
+
+
+ +
+
+ + +
Out[11]:
+ + +
+
+True
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Listes et dictionnaires

+

Souvent les données pertinentes doivent être agencées sous une forme +plus vaste, comme par exemple des listes où on peut ranger de façon ordonnée plusieurs valeurs.

+

Listes

+

Les listes sont des collections ordonnées de valeurs, elles sont +entourées par des crochets [], leurs éléments sont séparés par des +virgules.

+
+
+
+
+
+
In [12]:
+
+
+
a = [ 1, 'deux' , 3]
+type(a)
+
+ +
+
+
+ +
+
+ + +
Out[12]:
+ + +
+
+list
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut facilement accéder à la longueur de la liste grace à la fonction +len et à chacun de ces éléments grâce à leur index (Attention le +premier élement à l'index 0)

+
+
+
+
+
+
In [13]:
+
+
+
len(a)
+
+ +
+
+
+ +
+
+ + +
Out[13]:
+ + +
+
+3
+
+
+ +
+ +
+
+ +
+
+
+
In [14]:
+
+
+
a[0], a[2]
+
+ +
+
+
+ +
+
+ + +
Out[14]:
+ + +
+
+(1, 3)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut inversement connaître l'indice correspondant à une valeur grâce à l'attribut index.

+
+
+
+
+
+
In [15]:
+
+
+
a.index(1), a.index('deux'), a.index(3)
+
+ +
+
+
+ +
+
+ + +
Out[15]:
+ + +
+
+(0, 1, 2)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Dictionnaires

+

Dans un dictionnaire les valeurs de la collection ne sont pas repéré par +un index, mais par une clé. Les dictionnaires sont entourés d'accolades {}.

+
+
+
+
+
+
In [16]:
+
+
+
a = { 'nom': 'Doe' , 'prenom': 'John', 'age': 77 }
+type(a)
+
+ +
+
+
+ +
+
+ + +
Out[16]:
+ + +
+
+dict
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Pour accéder aux éléments du dictionnaire, il suffit d'appeler la clé +correspondante, d'autres part la fonction len est égalemnt disponible.

+
+
+
+
+
+
In [17]:
+
+
+
len(a)
+
+ +
+
+
+ +
+
+ + +
Out[17]:
+ + +
+
+3
+
+
+ +
+ +
+
+ +
+
+
+
In [18]:
+
+
+
a['nom'], a['age']
+
+ +
+
+
+ +
+
+ + +
Out[18]:
+ + +
+
+('Doe', 77)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Modification des listes et dictionnaires

+

Les listes et dictionnaires sont des objets mutables, c'est à dire que l'on peut modifier leur contenu sans créer un nouvel objet. On dit qu'il s'agit de données non-persistantes.

+
+
+
+
+
+
In [19]:
+
+
+
# Valeurs initiales
+liste = [ 1, 'deux' , 3]
+dict = { 'nom': 'Doe' , 'prenom': 'John', 'age': 77 }
+print("Valeurs initiales:\n", liste, dict)
+
+# Modification des valeurs par assignation
+liste[1] = 2
+dict['age'] = 17
+
+print("Modification des valeurs par assignation:\n", liste, dict)
+
+# Ajout d'éléments
+liste.append(4)
+dict['nationalité'] = 'française'
+
+print("Ajout d'éléments:\n", liste, dict)
+
+# Suppression d'éléments
+liste.pop(0)
+dict.pop('age')
+
+print("Suppression d'éléments:\n", liste, dict)
+
+ +
+
+
+ +
+
+ + +
+
+
+Valeurs initiales:
+ [1, 'deux', 3] {'age': 77, 'nom': 'Doe', 'prenom': 'John'}
+Modification des valeurs par assignation:
+ [1, 2, 3] {'age': 17, 'nom': 'Doe', 'prenom': 'John'}
+Ajout d'éléments:
+ [1, 2, 3, 4] {'age': 17, 'nom': 'Doe', 'nationalité': 'française', 'prenom': 'John'}
+Suppression d'éléments:
+ [2, 3, 4] {'nom': 'Doe', 'nationalité': 'française', 'prenom': 'John'}
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Si on a besoin de modifier une liste ou un dictionnaire, mais que l'on veut garder une trace des objets initiaux, il faut commencer par en créer une copie, il ne suffit pas de créer une variable suplémentaire sans quoi cette variable serait elle aussi modifiée si l'objet initial changeait: l'assignation est dite par référence dans ce cas.

+
+
+
+
+
+
In [20]:
+
+
+
# Valeurs initiales
+L = [ 1, 'deux' , 3]
+print("Valeurs initiales:\n", L)
+
+# Création d'une référencxe à la liste par simple assignation
+L_ref = L
+
+# Création d'une copie de la liste
+L_copie = list(L)
+
+# Modification de la liste initiale
+L[1] = 2

Entrée des données

+

Dans cette phase peut aussi figurer ce qu’on appelle l’entrée des +données, qui peut se manifester par la saisie de caractères ou de +nombres sur le clavier, ou la lecture de la position du pointeur de la +souris, ou encore par la lecture d’un fichier contenant ces nombres ou +caractères.

+

Il s’agit aussi de repérer les résultats intermédiaires qu’il est bon de +mémoriser pour la suite car indispensables au traitement.

+

Il est parfois utile d’utiliser des variables auxiliaires pour ne pas +perturber les données initiales.

+

Loading a notebook nbformat = 4.0

+

+

+
+
+
+
+

Il s’agit de repérer les données nécessaires voire indispensables à la +résolution. Ces données peuvent être:

+
    +
  • numériques,
    • +
  • ou sous forme de textes (on dit souvent chaînes de caractères),
    • +
  • ou de type logique (à deux valeurs possibles, vrai ou faux).
    • +
+

Pour affecter une valeur à une variable en python, la syntaxe est de la forme:

+
nom = valeur
+
+
Affectation
+
Dans un programme, une affectation donne une valeur à une variable, elle est de la forme v = e avec v une variable et e une expression. +
+
+ +

Valeurs numériques

+

Python distingue les entiers(integers), des nombres à +virgule(floating-point) par l'ajout d'une virgule:

+
+
+
+
+
+
In [2]:
+
+
+
a = 1
+b = 1.0
+
+print(a, type(a), b, type(b))
+
+ +
+
+
+ +
+
+ + +
+
+
+1 <class 'int'> 1.0 <class 'float'>
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Mais il implémente aussi des nombres plus exotiques tels que les +décimaux, les fractions ou encore les nombres complexes

+

Chaînes de caractères

+

En python3, il existe deux grands types de chaînes de caractères, les +strings, et les bytes. Les strings sont simplement entourées par des +guillemets simples ou doubles.

+
+
+
+
+
+
In [3]:
+
+
+
a = 'Mon texte'
+b = "Mon deuxième texte"
+
+print(a, type(a), b, type(b))
+
+ +
+
+
+ +
+
+ + +
+
+
+Mon texte <class 'str'> Mon deuxième texte <class 'str'>
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Les bytes sont précédées de la lettre b, il s'agit de texte brut utilisé +par la machine mais pas toujours lisible par un humain.

+
+
+
+
+
+
In [4]:
+
+
+
a = b'Mon texte'
+print(a, type(a))
+
+ +
+
+
+ +
+
+ + +
+
+
+b'Mon texte' <class 'bytes'>
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

On ne peut représenter simplement que certains caractères(les caractères +ASCII), les caractères accentués ne peuvent être écrits directement.

+
+
+
+
+
+
In [5]:
+
+
+
b = b'Mon deuxième texte'
+
+ +
+
+
+ +
+
+ + +
+
+
+  File "<ipython-input-5-b0bf0ef2715d>", line 1
+    b = b'Mon deuxième texte'
+       ^
+SyntaxError: bytes can only contain ASCII literal characters.
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Un encodage autre que le ASCII doit être utilisé pour ces caractères, +comme par exemple le UTF-8 qui est un codage sur huit bits très répandu.

+
+
+
+
+
+
In [6]:
+
+
+
b = b'Mon deuxi\xc3\xa8me texte'
+print(b)
+print(b.decode('utf-8'))
+
+ +
+
+
+ +
+
+ + +
+
+
+b'Mon deuxi\xc3\xa8me texte'
+Mon deuxième texte
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Valeurs logiques

+

On les appelle les booléens, il ne peuvent avoir que deux valeurs:

+
    +
  • VRAI ou FAUX: True ou False en anglais;
    • +
  • 1 ou 0.
    • +
+

On les utilise pour réaliser des tests.

+
+
+
+
+
+
In [7]:
+
+
+
1 < 2, 1 > 2, 2 == 10, 2 >= 1.9, 2 == 2, 2 != 2
+
+ +
+
+
+ +
+
+ + +
Out[7]:
+ + +
+
+(True, False, False, True, True, False)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut aussi les utiliser pour savoir si une variable existe.

+
+
+
+
+
+
In [8]:
+
+
+
bool(a)
+
+ +
+
+
+ +
+
+ + +
Out[8]:
+ + +
+
+True
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut aussi combiner plusieurs tests avec les opérateurs booléens and, or et not.

+
+
+
+
+
+
In [9]:
+
+
+
1 < 2 or 2 < 1
+
+ +
+
+
+ +
+
+ + +
Out[9]:
+ + +
+
+True
+
+
+ +
+ +
+
+ +
+
+
+
In [10]:
+
+
+
1 < 2 and 2 < 1
+
+ +
+
+
+ +
+
+ + +
Out[10]:
+ + +
+
+False
+
+
+ +
+ +
+
+ +
+
+
+
In [11]:
+
+
+
not(1 < 2 and 2 < 1)
+
+ +
+
+
+ +
+
+ + +
Out[11]:
+ + +
+
+True
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Listes et dictionnaires

+

Souvent les données pertinentes doivent être agencées sous une forme +plus vaste, comme par exemple des listes où on peut ranger de façon ordonnée plusieurs valeurs.

+

Listes

+

Les listes sont des collections ordonnées de valeurs, elles sont +entourées par des crochets [], leurs éléments sont séparés par des +virgules.

+
+
+
+
+
+
In [12]:
+
+
+
a = [ 1, 'deux' , 3]
+type(a)
+
+ +
+
+
+ +
+
+ + +
Out[12]:
+ + +
+
+list
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut facilement accéder à la longueur de la liste grace à la fonction +len et à chacun de ces éléments grâce à leur index (Attention le +premier élement à l'index 0)

+
+
+
+
+
+
In [13]:
+
+
+
len(a)
+
+ +
+
+
+ +
+
+ + +
Out[13]:
+ + +
+
+3
+
+
+ +
+ +
+
+ +
+
+
+
In [14]:
+
+
+
a[0], a[2]
+
+ +
+
+
+ +
+
+ + +
Out[14]:
+ + +
+
+(1, 3)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

On peut inversement connaître l'indice correspondant à une valeur grâce à l'attribut index.

+
+
+
+
+
+
In [15]:
+
+
+
a.index(1), a.index('deux'), a.index(3)
+
+ +
+
+
+ +
+
+ + +
Out[15]:
+ + +
+
+(0, 1, 2)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Dictionnaires

+

Dans un dictionnaire les valeurs de la collection ne sont pas repéré par +un index, mais par une clé. Les dictionnaires sont entourés d'accolades {}.

+
+
+
+
+
+
In [16]:
+
+
+
a = { 'nom': 'Doe' , 'prenom': 'John', 'age': 77 }
+type(a)
+
+ +
+
+
+ +
+
+ + +
Out[16]:
+ + +
+
+dict
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Pour accéder aux éléments du dictionnaire, il suffit d'appeler la clé +correspondante, d'autres part la fonction len est égalemnt disponible.

+
+
+
+
+
+
In [17]:
+
+
+
len(a)
+
+ +
+
+
+ +
+
+ + +
Out[17]:
+ + +
+
+3
+
+
+ +
+ +
+
+ +
+
+
+
In [18]:
+
+
+
a['nom'], a['age']
+
+ +
+
+
+ +
+
+ + +
Out[18]:
+ + +
+
+('Doe', 77)
+
+
+ +
+ +
+
+ +
+
+
+
+
+
+

Modification des listes et dictionnaires

+

Les listes et dictionnaires sont des objets mutables, c'est à dire que l'on peut modifier leur contenu sans créer un nouvel objet. On dit qu'il s'agit de données non-persistantes.

+
+
+
+
+
+
In [19]:
+
+
+
# Valeurs initiales
+liste = [ 1, 'deux' , 3]
+dict = { 'nom': 'Doe' , 'prenom': 'John', 'age': 77 }
+print("Valeurs initiales:\n", liste, dict)
+
+# Modification des valeurs par assignation
+liste[1] = 2
+dict['age'] = 17
+
+print("Modification des valeurs par assignation:\n", liste, dict)
+
+# Ajout d'éléments
+liste.append(4)
+dict['nationalité'] = 'française'
+
+print("Ajout d'éléments:\n", liste, dict)
+
+# Suppression d'éléments
+liste.pop(0)
+dict.pop('age')
+
+print("Suppression d'éléments:\n", liste, dict)
+
+ +
+
+
+ +
+
+ + +
+
+
+Valeurs initiales:
+ [1, 'deux', 3] {'age': 77, 'nom': 'Doe', 'prenom': 'John'}
+Modification des valeurs par assignation:
+ [1, 2, 3] {'age': 17, 'nom': 'Doe', 'prenom': 'John'}
+Ajout d'éléments:
+ [1, 2, 3, 4] {'age': 17, 'nom': 'Doe', 'nationalité': 'française', 'prenom': 'John'}
+Suppression d'éléments:
+ [2, 3, 4] {'nom': 'Doe', 'nationalité': 'française', 'prenom': 'John'}
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+

Si on a besoin de modifier une liste ou un dictionnaire, mais que l'on veut garder une trace des objets initiaux, il faut commencer par en créer une copie, il ne suffit pas de créer une variable suplémentaire sans quoi cette variable serait elle aussi modifiée si l'objet initial changeait: l'assignation est dite par référence dans ce cas.

+
+
+
+
+
+
In [20]:
+
+
+
# Valeurs initiales
+L = [ 1, 'deux' , 3]
+print("Valeurs initiales:\n", L)
+
+# Création d'une référencxe à la liste par simple assignation
+L_ref = L
+
+# Création d'une copie de la liste
+L_copie = list(L)
+
+# Modification de la liste initiale
+L[1] = 2
+
+print("Modification de la liste L:")
+print("La liste L a bien, été modifiée:", L)
+print("La liste L_ref a aussi été modifiée car il s'agit juste d'une référence vers la liste L:", L_ref)
+print("La copie L_copie n'a pas été modifiée:", L_copie)
+
+ +
+
+
+ +
+
+ + +
+
+
+Valeurs initiales:
+ [1, 'deux', 3]
+Modification de la liste L:
+La liste L a bien, été modifiée: [1, 2, 3]
+La liste L_ref a aussi été modifiée car il s'agit juste d'une référence vers la liste L: [1, 2, 3]
+La copie L_copie n'a pas été modifiée: [1, 'deux', 3]
+
+
+
+
+ +
+
+ +
+
+
+
+
+
+
