Este disponibil\u0103 versiunea proiectului PoCL 1.3 (Portable Computing Language OpenCL), care dezvolt\u0103 implementarea standardului OpenCL, independent de produc\u0103torii de acceleratoare grafice \u0219i permite utilizarea diferitelor backenduri pentru executarea nucleelor OpenCL pe diferite tipuri de procesoare grafice \u0219i centrale. Codul proiectului este distribuit sub licen\u021ba MIT. Func\u021bioneaz\u0103 pe platformele X86_64, MIPS32, ARM v7, AMD HSA APU \u0219i diferite procesoare TTA specializate (Transport Triggered Architecture) cu arhitectur\u0103 VLIW.<\/p>\n

Implementarea compilatorului de nucleu OpenCL se bazeaz\u0103 pe LLVM, iar Clang este utilizat ca frontend pentru OpenCL C. Pentru a asigura portabilitate \u0219i performan\u021b\u0103 adecvat\u0103, compilatorul nucleelor OpenCL poate genera func\u021bii combinate care pot utiliza diverse resurse hardware pentru a paraleliza executarea codului, precum VLIW, supercalaritate, SIMD, SIMT, multicore \u0219i multithreading. Exist\u0103 suport pentru drivere ICD
\n(Installable Client Driver). Exist\u0103 backenduri pentru asigurarea func\u021bion\u0103rii prin CPU, ASIP (TCE\/TTA), GPU bazate pe arhitectura HSA \u0219i GPU NVIDIA (CUDA). <\/p>\n

Noua versiune adaug\u0103 suport pentru LLVM\/Clang 8.0. Suportul ICD (Installable Client Driver) este asigurat pe platforma macOS. A fost implementat\u0103 posibilitatea de a monta pocl f\u0103r\u0103 driverele backend pentru CPU. Pentru HSA (Heterogeneous System Architecture) este prezentat un suport ini\u021bial pentru compilarea ISA deasupra runtime-ului HSA. A fost realizat\u0103 cur\u0103\u021barea bazei de cod, inclusiv eliminarea bibliotecii Vecmathlib \u0219i oprirea suportului pentru versiunile vechi de LLVM (mai mici de 6.0).
