[Trilinos-Users] Question about Make -j

[Bartlett, Roscoe A]

Matt,

I use 'make -jN' (where N=4, 8, etc.) all of the time and it seems to work perfectly.  All of the Trilinos test scripts using parallel builds.  If this does not work let me know.

Subject: [Trilinos-Users] Question about Make -j

I am going through a number of possible Trilinos configurations using different blas/lapack/mpi to probe performance.  Ideally I want to automate the compilation and profiling, and the slowest part is the compilation. I know Trilinos 9 has some issues that made parallel make (make -j) behave unpredictably.  Does anyone have some experiences trying this under the cmake based 10 branch?

Thanks.
