FOLASAGA

O le Intel® oneAPI DPC++/C++ Compiler e tu'uina atu fa'ata'ita'iga e fesoasoani i au talosaga e fa'agasolo vave i Intel® 64 fa'ata'ita'iga i Windows* ma Linux*, fa'atasi ai ma le lagolago mo le gagana C, C++, ma le SYCL aupito lata mai. O lenei tu'ufa'atasiga e maua ai le code sili ona lelei e mafai ona fa'avavevave e ala i le ave o le advantage o le fa'atuputeleina o le numera autu ma le lautele o le tusi resitala i totonu o Intel® Xeon® processors ma mea fa'aoga talafeagai. Ole Intel® Compiler o le a fesoasoani ia te oe e faʻaleleia le faʻatinoga o talosaga e ala i faʻataʻitaʻiga sili atu ma le faʻaogaina o le Single Instruction Multiple Data (SIMD), faʻatasi ma Intel® Performance Libraries, ma e ala i le faʻaogaina o le OpenMP* 5.0/5.1 faʻataʻitaʻiga polokalame tutusa.

O le Intel® oneAPI DPC++/C++ Compiler e tu'ufa'atasia C++-fa'avae SYCL* puna files mo le tele o fa'aputuga fa'avavevave.
