# Frequently Asked Questions
|
|
|
|
## How do I register for Merlin?
|
|
|
|
See [Requesting Merlin Access](../merlin7/01-Quick-Start-Guide/requesting-accounts.md).
|
|
|
|
## How do I get information about downtimes and updates?
|
|
|
|
See [Get updated through the Merlin User list!](index.md#merlin-user-mailing-list)
|
|
|
|
## How can I request access to a Merlin project directory?
|
|
|
|
Merlin projects are placed in the `/data/project` directory. Access to each
|
|
project is controlled by Unix group membership. If you require access to an
|
|
existing project, please request group membership as described in
|
|
[Requesting Unix Group Membership](../merlin7/01-Quick-Start-Guide/requesting-projects.md#requesting-unix-group-membership).
|
|
|
|
Your project leader or project colleagues will know what Unix group you should
|
|
belong to. Otherwise, you can check what Unix group is allowed to access that
|
|
project directory (simply run `ls -ltrhd` for the project directory).
|
|
|
|
## Can I install software myself?
|
|
|
|
Most software can be installed in user directories without any special
|
|
permissions. We recommend using `/data/user/$USER/bin` for software since home
|
|
directories are fairly small. For software that will be used by multiple
|
|
groups/users you can also [request the admins](index.md) install it as a
|
|
[module](../merlin7/05-Software-Support/pmodules.md).
|
|
|
|
How to install depends a bit on the software itself. There are three common
|
|
installation procedures:
|
|
|
|
* *binary distributions*. These are easy; just put them in a directory (eg
|
|
`/data/user/$USER/bin`) and add that to your PATH.
|
|
* *source compilation* using make/cmake/autoconfig/etc. Usually the
|
|
compilation scripts accept a `--prefix=/data/user/$USER` directory for where
|
|
to install it. Then they place files under `<prefix>/bin`, `<prefix>/lib`,
|
|
etc. The exact syntax should be documented in the installation instructions.
|
|
!!! note inline end
|
|
The following is based on `merlin6`, but should still be valid for `merlin7`.
|
|
* *conda environment*. This is now becoming standard for python-based
|
|
software, including lots of the AI tools. First follow the [initial setup
|
|
instructions](../merlin6/software-support/python.md#anaconda) to configure conda to
|
|
use /data/user instead of your home directory. Then you can create
|
|
environments like:
|
|
|
|
```bash
|
|
module load anaconda/2019.07
|
|
# if they provide environment.yml
|
|
conda env create -f environment.yml
|
|
|
|
# or to create manually
|
|
conda create --name myenv python==3.9 ...
|
|
|
|
conda activate myenv
|
|
```
|
|
|
