\u00c8 disponibile il rilascio del progetto PoCL 1.3 (Portable Computing Language OpenCL), che sviluppa un'implementazione dello standard OpenCL indipendente dai produttori di acceleratori grafici e consente l'uso di diversi backend per l'esecuzione di kernel OpenCL su vari tipi di processori grafici e centralizzati. Il codice del progetto \u00e8 distribuito con licenza MIT. \u00c8 supportato il funzionamento su piattaforme X86_64, MIPS32, ARM v7, AMD HSA APU e vari processori TTA specializzati (Transport Triggered Architecture) con architettura VLIW.<\/p>\n

L'implementazione del compilatore dei nuclei OpenCL \u00e8 basata su LLVM, mentre Clang \u00e8 utilizzato come frontend per OpenCL C. Per garantire la giusta portabilit\u00e0 e prestazioni, il compilatore dei nuclei OpenCL pu\u00f2 generare funzioni combinate che utilizzano diverse risorse hardware per parallelizzare l'esecuzione del codice, come VLIW, superscalare, SIMD, SIMT, multicore e multithreading. \u00c8 supportato il driver ICD
\n(Installable Client Driver). Sono presenti backend per garantire il funzionamento tramite CPU, ASIP (TCE\/TTA), GPU basate su architettura HSA e GPU NVIDIA (CUDA). <\/p>\n

Nella nuova versione \u00e8 stata aggiunta la supporto per LLVM\/Clang 8.0. \u00c8 garantito il supporto ICD (Installable Client Driver) sulla piattaforma macOS. \u00c8 stata realizzata la possibilit\u00e0 di compilare pocl senza driver backend per CPU. Per HSA (Heterogeneous System Architecture) \u00e8 stata introdotta la supporto iniziale per la compilazione ISA sopra HSA runtime. \u00c8 stata effettuata una pulizia del codice, inclusa la rimozione della libreria Vecmathlib e l'interruzione del supporto per le vecchie versioni di LLVM (inferiori a 6.0).
