Re: [eigen] Updating the Benchmarks

[Gael Guennebaud <gael.guennebaud@xxxxxxxxx>]

btw, if you plane to bench matrix size up to 9000x9000, make sure you
disable the non optimized libraries like GMM, ublas, blitz, etc.
because they will take forever. Also make sure you disable the result
verifications when running the tests (BTL_CONFIG="--nocheck).


BLAS and lapack libs are very very painful regarding
configuration/linking Depending on how the libs have been generated
you might need very different settings. That's why you have these
trouble. That's also a non negligible advantage of Eigen.
