Fig. 1

Schematics of the PARAEXP algorithm [10]. Solid red lines represent the solutions of inhomogeneous problems with zero initial value on each time slice \([T_{j-1},T_j]\), computed in parallel. Blue dashed lines represent the solutions of homogeneous problems on time intervals \([T_j,T]\), also computed in parallel
