Log Summary on Various Processors

Note: Double/Single precision just refers to the way preconditioner matrix is stored; the computation is always carried out in double precision (except when streaming SIMD enabled computations in MatSolve phase are done on Pentium 4). Wherever not stated, double precision storage should be assumed.
