This section explains how to setup and configure the FLARECAST development infrastructure on your personal computer.
Getting ready
Install software
| Software | OS X | Linux |
|---|---|---|
| Python | Install https://www.python.org/downloads/release/python-2711/ | Should be preinstalled. Test with python --version Otherwise check here. |
| PIP (Python installer) | PIP is shipped with Python 2.7.9+ and Python 3.4+. pip --version If you don't have it follow https://pip.pypa.io/en/stable/installing/ | |
| Python IDE | We suggest PyCharm, but any text editor or Spyder will work as well. | |
| IDL | You can use your normal IDL setup to access data and prototype your algorithms. Note: We do not support execution of IDL code on our cluster due to licensing issues. Let us know if this is a problem. Please avoid SolarSoft/SSW-specific functionality in your algorithms. They tend to be hard to be ported to a cluster. | |
Git (source code repository) |
|
|
Docker and docker-compose | Requires Kernel 3.10+ sudo curl -L https://get.docker.com/ | sh sudo pip install docker-compose | Install https://www.docker.com/docker-toolbox |
Access to Infrastructure
This step is required to get access either to the HMI files stored in France or the properties extracted by our algorithms.
If you want to do all processing on your local machine, you can skip this step.
In order to access the FLARECAST development infrastructure in France you need a dedicated account.
To get an account send a message to Eric Buchlin <eric.buchlin@ias.u-psud.fr>.
With this account you can connect to the computing infrastructure. The following figure outlines how this connection is being established.
Within this process you will be asked twice to enter your credentials. If you want to avoid this you can generate and install an SSH certificate as follows:
local> ssh-keygen -t rsa -C "your-mail-address" # -C is just a comment Enter file in which to save the key (/Users/mercuron/.ssh/id_rsa): # use default Enter passphrase (empty for no passphrase): # protect your private key Enter same passphrase again: # protect your private key ... Your public key has been saved in ~/.ssh/id_rsa.pub. ... local> scp ~/.ssh/id_rsa.pub username@ias-ssh.ias.u-psud.fr:~/.ssh/authorized_keys
local> ssh username@ias-ssh.ias.u-psud.fr inf-ssh2> ssh-keygen -t rsa -C "your-mail-address" # -C is just a comment # use default settings and no password inf-ssh2> scp ~/.ssh/id_rsa.pub username@cluster-head:~/.ssh/authorized_keys inf-ssh2> ssh username@cluster-head # to test the connection cluster-head> exit inf-ssh2> exit local>
# create file .ssh/config to auto-forward yourself to cluster-head local> nano .ssh/config # content of .ssh/config Host flarecast-infra ProxyCommand ssh username@ias-ssh.ias.u-psud.fr nc cluster-head.ias.u-psud.fr 22 User username ForwardX11Trusted yes ServerAliveInterval 60 # Ctrl-x y <return> to save and close local> ssh flarecast-infra # accept fingerprint # enter FLARECAST cluster password # you can ignore message: /usr/bin/xauth: file ~/.Xauthority does not exist cluster-head> exit local>
From now on you can login to the cluster as follows
local> ssh flarecast-infra # enter FLARECAST cluster password cluster-head> exit local>
Test installation
Note: Windows has not been tested yet
* OS X or Linux (we have not tested Windows installations yet)
* Python 2.7
* Text Editor or your preferred Python Interactive Development Environment (IDE).
* Account to connect to the FLARECAST infrastructure at OBSPM.
