[Trilinos-Users] Slow AztecOO solve time

Hello,

I'm a student, and a beginner with Trilinos trying to use the AztecOO 
solver in a SPICE package.   I am getting relatively slow results, 
mostly due to memory allocation and de-allocation. I have tried using 
the AZ_reuse and AZ_keep_info options, but neither seemed to affect the 
solve time.

I am calling reset after each solve. Is this part of the problem? I 
appreciate any insight.

Thanks,
Neal Parsons
