  1. *The generation of warmup points of E_Matrix and Ec_Matrix models did not converge after 20000s. The creation of warmup points can vary widely between runs as it involves the generation of a random c vector in the linear program. The runs were repeated three times and the average was reported.
  2. The run times of the generation of 30,0000 warmup points for sampling of six metabolic models using the standard serial implementation createWarmupMATLAB and the dynamic load balanced implementation createWarmupVF
