<div>You can delete the object files and libraries that are created during the compilation of cp2k with
<span>e.g. "make ARCH=Linux-x86-64-gfortran VERSION=psmp clean" (choose the correct ARCH=).</span>
</div><div><br></div><div>You can also remove most of the tools/toolchain/* directory. It depends a bit on how you built cp2k. You can check which directories you have to keep with "ldd cp2k.psmp". This lists all the libraries that cp2k depends on. Whatever directory is not listed there you can remove from toolchain/install. toolchain/build can be completely removed.<br></div><div><br></div><div>Cheers,</div><div>Fabian<br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Thursday, 11 March 2021 at 04:07:08 UTC+1 ic...@gmail.com wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div>I've really built everything except for GCC and cuda.

The only thing I can surmise is that you installed *absolutely everything* related to cp2k including intel and gnu packages and cuda and what not. Some of this stuff should definitely be stored in the common software by your HPC team and not be needed. If it really is impossible for you to access them, then you should contact the admins. </div><div><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Wednesday, March 10, 2021 at 10:36:26 AM UTC-8 <a rel="nofollow">ic...@gmail.com</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Dear cp2k community!<br><div><br></div><div>I've installed cp2k compiling all the libraries in my directory as I work on HPC cluster and don't have access to system directories.</div><div><br></div><div>Now it's taking lots of disk space (~30 Gb) and I want to get rid of all the unnecessary files.</div><div><br></div><div>Which folders can be safely deleted after the installation not to destroy my installation?<br></div><div><br><br></div></blockquote></div></blockquote></div></blockquote></div>
