Il codice del progetto \u00e8 distribuito con licenza MIT. \u00c8 supportato su piattaforme X86_64, MIPS32, ARM v7, AMD HSA APU, GPU NVIDIA e vari processori ASIP (Application-Specific Instruction-set Processor) e TTA (Transport Triggered Architecture) con architettura VLIW.    <\/p>\n<p>L'implementazione del compilatore per i nuclei OpenCL \u00e8 basata su LLVM, e come frontend per OpenCL C viene utilizzato Clang. Per garantire la necessaria portabilit\u00e0 e prestazioni, il compilatore dei nuclei OpenCL pu\u00f2 generare funzioni combinate, che possono utilizzare diverse risorse hardware per parallelizzare l'esecuzione del codice, come VLIW, superscalabilit\u00e0, SIMD, SIMT, multi-core e multithreading. \u00c8 presente il supporto per i driver ICD (Installable Client Driver). Sono disponibili backend per garantire il funzionamento attraverso CPU, ASIP (TCE\/TTA), GPU basate su architettura HSA e GPU NVIDIA (tramite libcuda).     <\/p>\n<p>Nella nuova versione:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stato implementato un insieme minimo di funzionalit\u00e0 richiesto per supportare la specifica OpenCL 3.0.

1.2).\n<li class=\"l\"> Aggiunto supporto per Clang\/LLVM 14.\n<li class=\"l\"> Migliorata la tracciatura e la visualizzazione.\n<li class=\"l\"> Aggiunto supporto per la generazione di gruppi di
