Fsdp Qlora

Dieses Framework bietet ein Toolkit für das Fine-Tuning großer Sprachmodelle durch die Kombination von verteilter Datenparallelität mit Parameter-Sharding und Quantisierungstechniken. Es wurde entwickelt, um das Training massiver neuronaler Netze über mehrere Grafikprozessoren hinweg zu skalieren und so die Ausführung von Modellen zu ermöglichen, die die Speicherkapazität einzelner Hardwareeinheiten übersteigen.

Die Bibliothek zeichnet sich durch die Integration von Low-Rank-Adaption mit speichereffizientem Laden von Gewichten und quantisierungsbewusstem Parameter-Sharding aus. Durch die Initialisierung von Modellgewichten direkt auf dem Grafikprozessor und die Anwendung einer granularen, schichtweisen Umhüllung minimiert das Framework Speicherspitzen und reduziert den Kommunikationsaufwand während der verteilten Setup- und Trainingsphasen.

Das System unterstützt das Training benutzerdefinierter Transformer-Architekturen durch flexible Wrapping-Richtlinien für Attention- und Multilayer-Perceptron-Schichten. Es optimiert die Ressourcennutzung weiter, indem es die numerische Präzision während der Berechnung dynamisch anpasst und so Trainingsstabilität gegen verfügbaren Hardwarespeicher abwägt. Das Projekt wird als Sammlung von Dienstprogrammen und Skripten vertrieben, die für den Einsatz in verteilten Rechenumgebungen vorgesehen sind.
