适用于 ARM 的英特尔 ISPC 1.26 还引入了新的 neon-i16x16 和 neon-i8x32 双泵目标,现在使用本机 ARM 指令支持点积作,据说 ARMv8 性能比以前的 ISPC 版本快了 13% 左右。 Intel ISPC 1.26 还为不同的 CPU 架构引入了新的通用目标,这使得添加 RISC-V 和其他 LLVM 支持的 CPU 目标变得更加容易。ISPC...
ISPC是Intel SPMD Program Compiler的缩写,是一种高性能的编译器,用于将SPMD(Single Program Multiple Data)并行模式的代码转换为CPU指令集,以在CPU上高效地执行并行计算任务。ISPC编译器支持C语言类似的语法,但还包括一些特殊的语言扩展,以支持向量化指令和并行计算。ISPC编译器会将这些扩展转化为SIMD指令,从而使得在...

其实UE在引擎中就集成了ISPC编译器,在引擎逻辑中,就大量使用了ISPC逻辑来加速动画/物理的运算。 #34;IntelISPC",就启用了ISPC编译器。 之后你可以在任何地方编写创建后缀名为 .ispc 的文件,编写ISPC逻辑(语法请查看前面给出的ISPC用户指南);UBT会为 .ispc 文件生成 .ispc.generated.h 文件,供C++逻辑调用。
因此我们使用ISPC也相当的方便,只需要在你的Module.Build.cs中,添加Denpendency:"IntelISPC",就启用了ISPC编译器。 之后你可以在任何地方编写创建后缀名为 .ispc 的文件,编写ISPC逻辑(语法请查看前面给出的ISPC用户指南);UBT会为 .ispc 文件生成 .ispc.generated.h 文件,供C++逻辑调用。

Essentially, Intel ISPC will explicitly vectorize your code to optimize it for various SIMD instruction sets on x86 (32 bit and 64 bit) and 64 bit ARM CPUs. It uses an SPMD (single program, multiple data) execution model that runs a number of program instances in parallel. ...
Is Intel Considering PC-133 Memory After All?
本次gdc中,intel和epic在chaos和animation模块做了ispc化的工作,也取得了不错的进展。 这里是chaos ispc on和off的对比,ispc都有一定的性能提升; 动画模块也是。 reference Intel ISPC in Unreal Engine 4: A Peek Behind the Curtain (Presented by Intel Corporation) ...
