Zeus is a cluster for public usage of researchers and advanced students at the Technion. The computers in the cluster are inter-connected with a fast infiniband network. They are intended to run parallel software using MPI.
The cluster is using Linux CentOS7 and is managed by a queuing system called PBS which stands for Portable Batch System.
Load and s/w management in the cluster is done by the queuing system Altair PBS
A brief description , usage instructions and example of running using the PBS queue management system can be found here
To run a job on the cluster, you will need to write a script in the PBS format and send it to a queue using the command qsub. The job script contain information on the resources requested for the calculation, as well as the commands for executing the calculation.
Running an interactive job on the cluster is not allowed
Once a job is finished, you can analise the data received on a dedicated server named zeus-post or transfer the data to your personal computer
There are 24 compute nodes by Lenovo on the cluster
Each node has 2 Intel processors of 20 cores each, all working in Hyper Threading mode. Altogether there are 960 cores and 1920 threads in the cluster.
InfiniBand switches by Mellanox are connecting the nodes, the speed is 100Gb.
The communication is managed by 1 GB switches
Central storage on NetApp
In addition, the cluster holds more compute nodes which belong to several research groups.
Researchers and research groups can buy compute nodes by the cluster standard and expansion policy and they will be connected to the Zeus cluster. These nodes will get fast communication services and storage services from the cluster and will be supported by the support team of the cluster.

It is recommended to install home edition of X-windows emulator MobaXterm (https://mobaxterm.mobatek.net/) on Windows machines to establish SSH connection.
ZEUS can be accessed via ssh from any computer within the Technion Network, using command
and applying Technion password.
