LNEC users The information contained on this chapter is complementary information specific for LNEC users that is not covered on the general guidelines Login Machine INCD-Lisbon ui6-lnec.a.acnca.pt Directories and filesystem CNCA-Lisbon The medusa cluster at CNCA-Lisbon (Cirrus-A) has the following Lustre filesystems. Lustre is a shared filesystem available both in the computing nodes and in the login nodes. Lustre is best suited for the storage of large/huge files. Summary Name Purpose Availability Quota TimeLimit Backup /home/lnec/user User default home always 2.7TB total for all users permanent no /data/lnec Group data large data files [4]. always 5.0 TB for all users temporary (can be deleted after 6 months) no /exper-sw/lnec Install software for groups on request 20GB/group permanent no MATLAB The MATLAB runtime compiler is available to the LNEC Medusa users. This software allows to use the Matlab compiled code in other machines without having Matlab installed. To use MATLAB in the Medusa cluster: load matlab/R2012a matlab/R2012a.i686 matlab/R2012b References[link] Agradecimentos / Créditos: Carlos M.
