I just use the official version of PETSC. Yes, see MatTransposeMatMult_MPIAIJ_MPIDense() in file petsc/src/mat/impls/aij/mpi/mpimattransposematmult.c Hong ----- Original Message ----- From: "Joon Hee Choi" < [email protected] > To: [email protected] Sent: Saturday, September 14, 2013 1:47:50 AM Subject: [petsc-users] The product of two MPIDENSE matrices Hello, I want to calculate M = C x C^T. C is a MPIDENSE matrix. I tried the calculation with MatTransposeMatMult (C, C, MAT_INITIAL_MATRIX, PETSC_DEFAULT, &M), but it did not support MPIDENSE. Is there any method to calculate the product of two MPIDENSE matrices? Thanks, Joon
