Introducing the Intel® Many Integrated Core (Intel® MIC) Class Libraries

This topic only applies to Intel® MIC Architecture.

The C++ Class Libraries for Intel® MIC enable Single Instruction, Multiple Data (SIMD) operations.

These libraries provide very similar functionality as the Intel® C++ Class Library does but for wider vectors. This functionality can be used in a code compiled for Intel® MIC Architecture.

For example, the Intel® C++ Class Library for SIMD Extensions 2 provides the following classes:

Instruction Set	Class	Signedness	Data Type	Size	Elements	Header File
SIMD Extensions 2	`F64vec2`	signed	`double`	64	2	`dvec.h`
	`I128vec1`	unspecified	`__m128i`	128	1	`dvec.h`
	`I64vec2`	unspecified	`long int`	64	4	`dvec.h`
	`Is64vec2`	signed	`long int`	64	4	`dvec.h`
	`Iu64vec2`	unsigned	`long int`	32	4	`dvec.h`
	`I32vec4`	unspecified	`int`	32	4	`dvec.h`
	`Is32vec4`	signed	`int`	32	4	`dvec.h`
	`Iu32vec4`	unsigned	`int`	32	4	`dvec.h`
	`I16vec8`	unspecified	`int`	16	8	`dvec.h`
	`Is16vec8`	signed	`int`	16	8	`dvec.h`
	`Iu16vec8`	unsigned	`int`	16	8	`dvec.h`
	`I8vec16`	unspecified	`char`	8	16	`dvec.h`
	`Is8vec16`	signed	`char`	8	16	`dvec.h`
	`Iu8vec16`	unsigned	`char`	8	16	`dvec.h`

Similarly, the Intel® MIC C++ Class Library provides the following classes (with similar functionality, but for wider vectors - 512bit instead of 128bit):

Instruction Set	Class	Signedness	Data Type	Size	Elements	Header File
Intel® MIC	`F64vec8`	signed	`double`	64	8	`micvec.h`
	`I64vec8`	unspecified	`long int`	64	8	`micvec.h`
	`F32vec16`	unspecified	`float`	32	16	`micvec.h`
	`I32vec16`	unspecified	`int`	32	16	`micvec.h`
	`Is32vec16`	signed	`int`	32	16	`micvec.h`
	`Iu32vec16`	unsigned	`int`	32	16	`micvec.h`
