[Trilinos-Users] [EXTERNAL] Re: Multigrid preconditioning with 64 bit support

[Heroux, Michael A]

ML does not support the "long long" map features in Epetra.  We do not plan to extent ML to support this feature, since Muelu is coming along and natively supports 64-bit types.

Subject: [EXTERNAL] Re: [Trilinos-Users] Multigrid preconditioning with 64 bit support

Hi Eric,
         I don't have a problem building ML on a 64 bit platform. I am trying to solve a large problem (strongly anisotropic poisson) and was wondering if ML has 64-bit support. Just to clarify, have you used ML in conjunction with long long Epetra_Map's?
I have no problem with ML up to Trilinos 10.10 but I just upgraded to 11.03 to solve bigger problems and have started getting errors when building the preconditioner.

Thanks for the help.

Hi,
I'm not sure exactly what kind of 64bit support you're looking
for, but I've built and used the ML package on 64-bit linux
without any issues.
