Abstract :
We are developing virtualization for an earth model, particularly cracks in the model. One part of the problem is the extensive computation due to the integral equation. Generally, these integral equations comes in the form of “very high oscillation” which make calculation time very long in order to obtain a precise solution. We develop the parallel this type of integral equations based on Message Passing Interface (MPI). The solver is based on the job scheduler model to balance loads for each node. The approach is compared to the static job distribution. It is found that the job scheduler approach is more appropriate to this type of integral solver. We obtain upto 34.46 for speedup rate while the static row distribution approach gives the speedup only 18.03 for a 32-node cluster.
