I guess Evren assumed that GROMACS has an explicit dependency on an external linear algebra library. To be concrete, you can simply use the GROMACS internal linear algebra code by setting -DGMX_EXTERNAL_BLAS=OFF -DGMX_EXTERNAL_LAPACK=OFF. -- Szilárd PS: This issue sounds like a valid reason to consider switching external BLAS/LAPACK off by default. > Cheers, > > Berk > > ---------------------------------------- > > Date: Thu, 7 Mar 2013 14:54:39 +0200 > > From: eyurt...@abo.fi > > To: gmx-users@gromacs.org > > Subject: RE: [gmx-users] Re: [gmx-developers] Gromacs 4.6.1 ATLAS/CUDA > detection problems... > > > > > > > > On Thu, 7 Mar 2013, Berk Hess wrote: > > > > > > > > Hi, > > > > > > Note that the linear algebra in Gromacs is limited to eigenvalue > solving in two analysis tools, > > > the MD engine does not use any (large) linear algebra. > > > So linear algebra library performance is irrelevant, except for the > cases where users > > > would want to repeated uses one of the two tools with large systems. > > > Even then, our built-in code is not bad. > > > > > > Cheers, > > > > > > Berk > > > > Hello, > > > > I am not sure what you are suggesting as a fix to the problem?
