Dostupan je projekt PoCL 1.3 (Portable Computing Language OpenCL), koji razvija implementaciju standarda OpenCL neovisno o proizvo\u0111a\u010dima grafi\u010dkih akceleratora i omogu\u0107uje kori\u0161tenje razli\u010ditih backendova za izvr\u0161avanje OpenCL jezgri na razli\u010ditim vrstama grafi\u010dkih i centralnih procesora. Izvorni kod projekta distribuira se pod MIT licencom. Podr\u017eava rad na platformama X86_64, MIPS32, ARM v7, AMD HSA APU i raznim specijaliziranim TTA procesorima (Transport Triggered Architecture) s VLIW arhitekturom.<\/p>\n

Implementacija OpenCL jezgri kompajlera temelji se na LLVM-u, dok se za frontend za OpenCL C koristi Clang. Kako bi se osigurala odgovaraju\u0107a prenosivost i performanse, kompajler OpenCL jezgri mo\u017ee generirati kombinirane funkcije koje mogu koristiti razli\u010dite hardverske resurse za paralelno izvr\u0161avanje koda, kao \u0161to su VLIW, superskalarnost, SIMD, SIMT, vi\u0161ejezgreni i vi\u0161edretveni. Podr\u0161ka za ICD drajvere je prisutna.
\n(Installable Client Driver). Postoje backendovi koji omogu\u0107uju rad putem CPU-a, ASIP-a (TCE\/TTA), GPU-a temeljenog na arhitekturi HSA i NVIDIA GPU-a (CUDA). <\/p>\n

Nova verzija dodaje podr\u0161ku za LLVM\/Clang 8.0. Osigurana je podr\u0161ka za ICD (Installable Client Driver) na macOS platformi. Implementirana je mogu\u0107nost izgradnje pocl bez backend drajvera za CPU. Za HSA (Heterogeneous System Architecture) predstavljena je osnovna podr\u0161ka za kompilaciju ISA preko HSA runtime-a. O\u010di\u0161\u0107en je kod, uklju\u010duju\u0107i uklanjanje biblioteke Vecmathlib i obustavu podr\u0161ke za starije verzije LLVM (manje od 6.0).
