[Trilinos-Users] Trilinos (Tpetra) creates ridiculously large executable and .o files

[Alicia Klinvex]

Hello Michael,

I suggest enabling explicit template instantiation in your configuration
script (-D Trilinos_ENABLE_EXPLICIT_INSTANTIATION:BOOL=ON) if you haven't
already.  If your compilation is taking too long, you can always try
parallel make (make -j[number]).

Best wishes,
Alicia
