Diese wird als Alternative zu Niedrigsprachen wie CUDA und Metal positioniert, und bietet einen ausdrucksstarken Syntax sowie Entwicklungsvereinfachungen, wie sie in Sprachen wie Python und Haskell zu finden sind. Der Code des Projekts ist in Rust geschrieben und steht unter der Lizenz Apache 2.0.          <\/p>\n<p>Die Sprache Bend zeichnet sich durch eine schnelle Objektverteilung, die Verwendung von Higher-Order-Funktionen, Closures, Continuations, unbeschr\u00e4nkten Rekursionen, Pattern Matching, rekursivem Matching (fold) und Schleifen (bend) sowie durch Integer-, String- und Listentypen aus. Es werden zwei Syntaxvarianten unterst\u00fctzt \u2014 im Python-Stil und im Haskell-Stil. In Programmen sind keine Anweisungen zur Parallelisierungssteuerung, zur expliziten Erstellung von Threads oder zur Setzung von Sperren erforderlich. Die Parallelisierung erfolgt automatisch, zum Beispiel bei der Berechnung des Ausdrucks \u201e((1 + 2) + (3 + 4))\u201c werden die Operationen \u201e1 + 2\u201c und \u201e3 + 4\u201c parallel ausgef\u00fchrt.     <\/p>\n<p> Programme in der Sprache Bend k\u00f6nnen auf Hardware ausgef\u00fchrt werden, die Massenausf\u00fchrungen unterst\u00fctzt, wie z. B. auf GPUs, und zeigen einen praktisch linearen Anstieg der Leistung in Abh\u00e4ngigkeit von der Anzahl der Rechenkerne. Der Code in der Sprache Bend wird in eine niedrigstufige Zwischenrepr\u00e4sentation HVM2 (Higher-order Virtual Machine 2) kompiliert, die dann in C- und CUDA-Repr\u00e4sentationen kompiliert wird. Derzeit wird die Ausf\u00fchrung nur auf NVIDIA-GPUs unterst\u00fctzt.           <\/p>\n<p>Was die Leistung betrifft, so wurde eine Testanwendung mit der Implementierung des bitonalen Sortierverfahrens auf dem CPU Apple M3 Max in 12,15 Sekunden ausgef\u00fchrt, bei der Verwendung von 16 Threads in 0,96 Sekunden und mit der GPU NVIDIA RTX 4090 und 16k Threads in 0,21 Sekunden.  def
