 BLUP90IOD2 is a BLUP program for solving a large number of mixed model equations, using preconditioned conjugate gradient (PCG). Another version for heterogeneous residual variances is also available.
+\\
+BLUP90IOD2 has 2 additional versions: BLUP90IOD2OMP1 with OpenMP and BLUP90IOD2MPI with MPI. The OpenMP version is faster running with multiple cores. The MPI version has the same computing speed as the OpenMP version with less memory when we use SSD.

 See PREGSF90 with genotypes (SNP) for options.
