This calculates the genomic relationship matrix using the formula in VanRaden (2008)

1 | ```
Amat.pieces(M, pieces=10, mc.cores=1)
``` |

`M` |
The matrix of markers rows rorresponding to individuals and columns for markers, the markers scores are coded as -1,0,1 (corresponding to allele counts 0,1,2). |

`pieces` |
number of chunks to split the markers |

`mc.cores` |
number of cores to use |

a genomic relationship matrix.
