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

[Michael Bieri]

Hi,

I just tried the hands on tutorial from here:
https://github.com/trilinos/Trilinos_tutorial/wiki/TrilinosHandsOnTutorial
. The first examples work fine, but when I compile Lesson 4 ("Learn how to
construct Tpetra matrices and vectors from existing Kokkos arrays.") I will
get extremely large executable and .o files, in the range of 10 - 40 GB (on
a Mac and a Linux computer). It seems to have something to do with Tpetra,
as the examples before Tpetra generate normal-sized executables.

I do not exactly know what information to provide, but at least the compile
command:

icpc-2013.sp1.1.106 -c -I/usr/local/mpich2-3.1.2/intel/include -std=c++11
-g -I/trilinos-12.6.3-Install/include -I/usr/include -DMYAPP_EPETRA main.cpp

Is it normal to have such big executables? What could be wrong?

Furthermore, with some uncertainity, as I just "remember":
I also observed that compilation took extremely long on the Linux machine
and I think it also generated very large files, because once I ran out of
disk memory (at least it said so). How large should Tpetra package be?

Best regards
Michael
