CytnxBenchmarks

Benchmarks for the Cytnx library.

Adding and running benchmark test case

Make sure you have your Cytnx, Itensor and Google Benchmark installed and include them in the Makefile properly, then just add your own benchmark .cpp files in this directory (also add them to the target in Makefile) and run make to generate the benchmark executable. Note that before running the executable you may want to specify the MKL and OMP # of thread, see run.sh for exmaple.

Note

If you want to include both of the header file <cytnx.hpp> and <itensor/all.h>, and the itensor library is compiled in mkl platform, you may encounter some redefinition errors, please command out the lines 114~118 in the file : <itensor path you installed>/itensor/tensor/lapack_wrap.h like:

//
//
// Intel MKL
//
//
#elif defined PLATFORM_mkl

#define ITENSOR_USE_CBLAS
#define ITENSOR_USE_ZGEMM

#include "mkl_cblas.h"
#include "mkl_lapack.h"
    namespace itensor {
    using LAPACK_INT = MKL_INT;
    using LAPACK_REAL = double;
    using LAPACK_COMPLEX = MKL_Complex16;

    //inline LAPACK_REAL& 
    //realRef(LAPACK_COMPLEX & z) { return z.real; }

    //inline LAPACK_REAL& 
    //imagRef(LAPACK_COMPLEX & z) { return z.imag; }
    }
