Cupy

CuPy ist eine CUDA-Array-Computing-Bibliothek, die eine NumPy-kompatible Schnittstelle für die Ausführung von Array-Operationen und numerischen Berechnungen auf NVIDIA GPUs implementiert. Sie dient als GPU-beschleunigte numerische Bibliothek und CUDA-basierte SciPy-Implementierung, die rechenintensive Aufgaben auf Grafikhardware auslagert, um die Verarbeitungsgeschwindigkeit für wissenschaftliche und technische Workloads zu erhöhen.

Die Bibliothek ermöglicht den Austausch von Tensoren zwischen verschiedenen Frameworks, wodurch Datenpuffer zwischen verschiedenen Deep-Learning-Frameworks unter Verwendung standardisierter Speicherlayouts geteilt werden können, um Speicherkopien zu vermeiden. Sie unterstützt zudem die Integration benutzerdefinierter GPU-Kernel, wodurch Array-Daten mit Low-Level-APIs verbunden werden können, um eine präzise Kontrolle über die Hardwareausführung zu ermöglichen.

Das Projekt deckt im Wesentlichen Workflows für Array-Verarbeitung und wissenschaftliches Rechnen mit hoher Leistung ab. Zu den Fähigkeiten gehören die Beschleunigung von Array-Berechnungen und die Bereitstellung von Werkzeugen für numerische Berechnungen im großen Maßstab.
