Re: [scipion-users] CPU acceleration in Relion installed via Scipion

[Jose M. de la R. T. <del...@gm...>]

Hi Derek,

If you want to have more control about Relion installation (and compilation
flags)
probably is a better idea to do it outside Scipion and then create the
proper link
in scipion/software/em/relion-3.0 -> /path/to/relion-3.0

Regarding CPU optimization, remember that this is exclusive with GPU
acceleration,
which I assume you want. Moreover, I'm not completely sure if for the
complete CPU
optimization, you need the Intel compiler (not GCC) which is not free.

Kind regards,
Jose Miguel
