Functions with information about library.
Function Documentation
◆ SimdVersion()
const char * SimdVersion | ( | ) |
Gets version of Simd Library.
- Returns
- string with version of Simd Library (major version number, minor version number, release number, number of SVN's commits).
◆ SimdCpuInfo()
size_t SimdCpuInfo | ( | SimdCpuInfoType | type | ) |
Gets info about CPU and Simd Library.
- Note
- See enumeration SimdCpuInfoType.
Using example:
#include "Simd/SimdLib.h" #include <iostream> int main() { std::cout << "Sockets : " << SimdCpuInfo(SimdCpuInfoSockets) << std::endl; std::cout << "Cores : " << SimdCpuInfo(SimdCpuInfoCores) << std::endl; std::cout << "Threads : " << SimdCpuInfo(SimdCpuInfoThreads) << std::endl; std::cout << "L1D Cache : " << SimdCpuInfo(SimdCpuInfoCacheL1) / 1024 << " KB" << std::endl; std::cout << "L2 Cache : " << SimdCpuInfo(SimdCpuInfoCacheL2) / 1024 << " KB" << std::endl; std::cout << "L3 Cache : " << SimdCpuInfo(SimdCpuInfoCacheL3) / 1024 << " KB" << std::endl; std::cout << "SSE: " << (SimdCpuInfo(SimdCpuInfoSse) ? "Yes" : "No") << std::endl; std::cout << "SSE2: " << (SimdCpuInfo(SimdCpuInfoSse2) ? "Yes" : "No") << std::endl; std::cout << "SSE3: " << (SimdCpuInfo(SimdCpuInfoSse3) ? "Yes" : "No") << std::endl; std::cout << "SSSE3: " << (SimdCpuInfo(SimdCpuInfoSsse3) ? "Yes" : "No") << std::endl; std::cout << "SSE4.1: " << (SimdCpuInfo(SimdCpuInfoSse41) ?

"Yes" : "No") << std::endl; std::cout << "AVX2: " << (SimdCpuInfo(SimdCpuInfoAvx2) ? "Yes" : "No") << std::endl; std::cout << "AVX-512F: " << (SimdCpuInfo(SimdCpuInfoAvx512f) ? "Yes" : "No") << std::endl; std::cout << "AVX-512BW: " << (SimdCpuInfo(SimdCpuInfoAvx512bw) ? "Yes" : "No") << std::endl; std::cout << "PowerPC-Altivec: " << (SimdCpuInfo(SimdCpuInfoVmx) ? "Yes" : "No") << std::endl; std::cout << "PowerPC-VSX: " << (SimdCpuInfo(SimdCpuInfoVsx) ? "Yes" : "No") << std::endl; std::cout << "ARM-NEON: " << (SimdCpuInfo(SimdCpuInfoNeon) ? "Yes" : "No") << std::endl; std::cout << "MIPS-MSA: " << (SimdCpuInfo(SimdCpuInfoMsa) ? "Yes" : "No") << std::endl; return 0; }
- Parameters
-

- Returns
- a value which contains information about CPU and Simd Library.
◆ SimdPerformanceStatistic()
const char * SimdPerformanceStatistic | ( | ) |
Gets internal performance statistics of Simd Library.
- Note
- Simd Library have to be build with defined SIMD_PERFORMANCE_STATISTIC macro.
- Returns
- string with internal performance statistics of Simd Library.
◆ PrintInfo()
void PrintInfo | ( | std::ostream & | os | ) |
Prints information about Simd Library and CPU properties.
- Parameters
-
[in,out] os - output stream.
