Hi, forgive me if this is a totally noob question, but I have a 64 bit install of ubuntu - does that mean all of the packages available through synaptic will be the 64 bit versions of the software? In particular I've installed the LAPACK and BLAS linear algebra packages - I've been told the 64 bit versions of these are considerably faster than the 32 bit versions, but it doesn't say in synaptic if they're 64 or 32 bit. Is there a way to check, or will they definitely be 64 bit? Thanks!
