Carma cluster

Carma cluster

Carma cluster

This cluster is composed of 4 Carma devkit. Each node is equipped with:
- a quad-core ARM Cortex-A9 CPU
- an NVIDIA Quadro 1000M GPU  (with 96 CUDA cores)
- a GigaEthernet network card
- a 4GB SD card that hosts the system filesystem

The nodes are connected to a Gigabit Ethernet switch.

Installing the system

As for the Odroid cluster, this cluster is connected to a server that serves as a frontend. This server (an old Xeon desktop machine) hosts:
- a NFS server that exports /home and /opt (where compiled software is installed)
- a LDAP server
- a DNS+DHCP server

Once the server is configured, the installation of the nodes is straightforward since most debian packages are available (nfs-common, libpam-ldapd, etc.)

Installing HPC software

Since we mainly work on MPI, we installed the latest versions of MPICH and Open-MPI from source without any problem. The installation is in /opt so that it is common for all the nodes of the cluster.
