Computer description

Description of supercomputers

The Institute of Integrative and Systems Biology has 2 computer servers: katak & manitou

These computers are primarily dedicated to high memory and time intensive computing jobs.
For mpi or serie calculations that do not require more than 24 GB of memory per node
(8 cores) and 48 hours of computing time, it is suggested to use the resources of Compute Canada.

katak

It’s a computer in the UV100 SGI series and was commissioned in June 2011.
It has an architecture SMP (symmetric multiprocessing) of ccNUMA class (cache coherent
non-uniform memory access). It has 64 processing cores and 1 terabyte of RAM.
katak’s addresse is:

katak.ibis.ulaval.ca

To connect to katak, open a terminal window and enter the command:

ssh -Y your_login@katak.ibis.ulaval.ca

Here is how the cores are used on katak:

  • 2 cores are dedicated for the OS
  • 2 cores are dedicated for ssh and the batch system SLURM
  • 60 cores are dedicated to the computing

manitou

It’s a computer in the series UV300 SGI and was commissioned in March
2016. He also has SMP architecture ccNUMA class with 128 processing cores and 2 terabytes
of RAM. The computer manitou is used primarily by two research teams. Users of other teams
also have access to this server with a lower priority.
manitou’s addresses is:
manitou.ibis.ulaval.ca

To connect to manitou, open a terminal window and enter the command:
ssh -Y your_login@manitou.ibis.ulaval.ca

Here is how the cores are used on manitou:

  • 128 processing cores dedicated to computation
  • 2 graphical processing units (GPU) NVIDIA 16G Tesla-P100
