Use of graphics cards and coprocessors for solving filtration problems

The implementation of the BiCGStab algorithm with the ILU(0) preconditioner on AMD and Nvidia graphics cards and on Intel Xeon Phi is considered. The test results obtained for different unsymmetric ill-conditioned matrices are discussed in the case of simulation of real oil fields with a large number of wells. The comparison of computing time of this algorithm on the four newest equal value AMD, Nvidia and Intel computational systems is analyzed.
