Great, apologies for not going through the SLEPc manual first, I thought I was fine with PETSc's. Anyway, I just run the same test and I got a neat, out-of-the-box 3x speedup compared to the single processor version [NVIDIA Tesla C2070 vs Intel Xeon X5650]. I will go through more extensive testing if we decide to continue using PETSc-SLEPc. Best, Massimiliano The data contained in, or attached to, this e-mail, may contain confidential information.
