Directories and filesystem
INCD-Lisbon
The medusa cluster at INCD-Lisbon 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.
- For more specific information regarding the Lustre deployment at INCD see the Lustre section
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 <name_of_the_module>
matlab/R2012a
matlab/R2012a.i686
matlab/R2012b

Job Queues
INCD-Lisbon
Job queues available for LNEC users.
List of Queues
| Name | Jobs max elapsed time | access | Memory | Max #cores[1] | Comments |
|---|---|---|---|---|---|
| medusa | 18 days | everyone | 6 GB/Core | 64 | default queue for LNEC users |
| fast_medusa | 24 hours | restricted[2] | 3 GB/Core | 32 | specific queue for short priority jobs |
| hpc | 72h | everyone | 6 GB/Core | 64 | default queue for all users no special priviligies |
[1] Maximum number of cores a user can request
[2] access based on evaluation and upon request
Special resources
Some LNEC users(*) have dedicated servers (gorgon201 and gorgon301) both accessible from medusa and fast_medusa queues. To use these nodes add one of the following lines to the submitted script.
- Access to gorgon201.ncg.ingrid.pt
#$ -l lnecit=y
- Access to gorgon301.ncg.ingrid.pt
#$ -l lnecintel=y
(*) on request
