Presentation
The front server is the server on which our infrastructure is based. You must have an account to access it. You can request it here. Find here the different ways to connect to migale (Windows, Linux, MacOS).
The domain name is front.migale.inrae.fr
This server provides access to computing resources and workspaces. Under no circumstances should it be used to run calculations.
Note
⚠️ We give ourselves the right to kill your processes if they do not respect this rule or if they degrade performance by impacting other users.
Access conditions
Our infrastructure is open to all public and private scientists working in the field of life sciences.
Unrestricted in time access for permanent people
Access limited to the duration of the contract for non-permanent people
You have to fill this form to request an account. A login and password will be sent to you as soon as possible after acceptance of your request.
Note
⚠️ You must enter a professional email address!
Working spaces
If the user stage01 belongs to the MaIAGE unit, the working spaces for stage01 are:
/home/stage01/
We provide you a work and save directory.
/home/stage01/save/
/home/stage01/work
Note
⚠️ Your home directory will be the stage01 directory.
Note
⚠️ Quotas are applied on each of these directory (home, save, work)
A complete description of the work spaces and advices on ho to use it are available in the Migale tutorial (in french)
You will find additional tips on our FAQ on how to to manage your work space.
Supplementary resources
If the default resources assigned to you are not sufficient, you can request for more disk space or for accessing a node with more memory than the others. The request must be made using this form. Depending on your needs, we will contact you to establish a quote if necessary.
Computer farm
The cluster farm is composed of about a thousand cores organized in different queues. We use the Sun Grid Engine queuing system for managing jobs.
Presentation
A computer cluster is a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software.
Access
An account allows you to have an access to the cluster farm via the front server. You need to log in and use dedicated commands to run your jobs to the cluster.
Sending jobs
You can send jobs to the cluster using the SGE job scheduler.
Learn here the basics of SGE with some typical examples.
Nodes
Users can access to tens of nodes, representing hundreds of cores.
Nodes
39
CPU
4 352
Memory
35.3 TB
Queues
The nodes are organized as queues. Each queue has particularities in terms of RAM memory, job duration listed in the table below.
Note
⚠️ Due to their specificity (high amount of RAM) queues bigmem.q and highmem.q are only available on demand after justification. You can ask for an access here.
Note
⚠️ maiage.q and web.q are queues restricted to authorized users
| Queue | Limit (hours) | Nodes |
|---|---|---|
| bigmem.q | Inf | bigmem |
| highmem.q | Inf | highmem1 highmem2 |
| infinit.q | Inf | n1 n10 n11 n12 n13 n14 n15 n16 n17 n18 n19 n2 n20 n21 n3 n4 n5 n6 n8 |
| long.q | 120 | n121 n122 n123 n124 n125 n126 n127 n128 n129 |
