Il codice del progetto \u00e8 distribuito sotto licenza MIT. \u00c8 supportato il funzionamento su piattaforme X86_64, MIPS32, ARM v7, AMD HSA APU, GPU NVIDIA e vari ASIP (Application-Specific Instruction-set Processor) e processori TTA (Transport Triggered Architecture) con architettura VLIW.    <\/p>\n<p>L'implementazione del compilatore dei kernel OpenCL \u00e8 basata su LLVM, mentre Clang funge da frontend per OpenCL C. Per garantire la dovuta portabilit\u00e0 e prestazioni, il compilatore dei kernel OpenCL pu\u00f2 generare funzioni combinate che possono utilizzare diverse risorse hardware per parallelizzare l'esecuzione del codice, come VLIW, superscalare, SIMD, SIMT, multicompatibilit\u00e0 e multithreading. \u00c8 presente il supporto per i driver ICD (Installable Client Driver). Sono disponibili backend per garantire il funzionamento tramite 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 richieste per supportare la specifica OpenCL 3.0.

OpenCL 1.2).\n<li class=\"l\"> Aggiunta la supporto per Clang\/LLVM 14.\n<li class=\"l\"> Migliorata la tracciabilit\u00e0 e la visualizzazione.\n<li class=\"l\"> Aggiunta la supporto per la
