The Hopper Cluster offers a free file transfer service through Globus. It is appropriate for transferring very large files between Hopper and other systems. Designed for researchers, Globus is fast, reliable, and secure. You can use it to transfer files between your local machine and a remote machine, like Hopper, or between any two remote machines on which you have...
Hopper provides a GPFS shared file system for users’ home directories and scratch space. While this file system provides outstanding performance and lots of space, there are limitations in regards to disk space and the number of files. Some Background Each unix file consists of two parts: 1) the data blocks that contain the contents of the file and 2)...
As the cluster tends to be busier during the weekdays, it may be advantageous to delay the execution of your job until evening or weekends. To set the date/time on which a job becomes eligible to run, use the -a option of the qsub command. It allows you to submit now, run later. Here’s an example that schedules a job...

As a “condo-model” cluster, Hopper is funded by a group of financial stakeholders known as Principle Investigators. Each PI maintains ownership of a subset of nodes within the cluster, and is guaranteed purchased processing power on demand. In mild contrast to this, a secondary goal of the machine is to promote efficiency through allowing all cluster researchers to leverage any...
Quite often, a very specific set of adjustments must be made to your shell environment in order to use a scientific software package. This requires knowledge of file tedious system specifics, and involves issuing a number of lengthy commands, such as: $ export PATH=$PATH:/a/binary $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/a/library. Environment modules make it easier to modify your environment, switch between different environments, and...

On Tuesday, January 19th, 2016 work started on the networking phase of the Auburn University “Hopper” High Performance Compute Cluster. This phase involved the routing of hundreds of InfiniBand, Ethernet and Fiber Optic cables, enabling high speed communication between the previously installed servers. The InfiniBand network architecture provides the cluster with high speed, low latency shared disk access and the...

On Monday, January 5, the build began on the new HPC cluster in the AU Data Center. Resembling an old fashioned ‘barn raising’, OIT and Lenovo personnel unboxed and racked equipment in step one of constructing Auburn’s newest and most powerful research computer. Work continues with the goal to be operational by mid-February.
