Island Facilitation

Island Facilitation

Foster’s rule (also known as the island rule or the island effect) is an ecogeographical rule in evolutionary biology stating that members of a species get smaller or bigger depending on the resources available in the environment. Source: https://en.wikipedia.org/wiki/Foster’s_rule Cyberinfrastructure at the University of Hawaii is relatively new and small compared to the other organizations […]

New Annual Conference – PEARC

New Annual Conference – PEARC

The annual XSEDE conference will be changing into a new conference called “Practice and Experience in Advanced Research Computing” or PEARC.  The Advancing Research Computing on Campuses (ARCC) best practices workshop, a conference with close ties to ACI-REF, will be co-located with this inaugural PEARC conference, bringing together members of each group in the same time […]

On Equity and the Long Tail

On Equity and the Long Tail

One of our most common roles as a facilitator is as “teacher” to the researchers whose work we facilitate. It’s a role that not only requires a good set of communication skills, but also a knowledge of what our learners (researchers) already know, what they need to know, and what learning steps are necessary along […]

On Building a fast R environment

On Building a fast R environment

In this article we will describe how to build an R distribution from source using the Intel Compiler Suite. Why? The execution of R code can be significantly sped up when it is built with a decent compiler and relies on fast mathematical libraries (mainly linear algebra). Requirements The installation (vide infra) was performed on […]

Software Installation for Researchers...

I recently attended the ACI-REF Virtual Residency 2016 workshop where we discussed, among other things, how and when different computing centers should install software for their researchers. The conversation was surprisingly lively because installing software is a topic that touches on many regimes of facilitation. Since every institution has its own perspective, I thought it […]

When a lot of little things add up to...

HTC in GIS

A student sits at his desk, fretting. The clock is ticking, the deadline is looming, and the giant mound of data he desperately needs processed remains, stubbornly and unabashedly, unaltered. He’s tried many things, but it’s only him and his workstation against the monstrosity of information he’s attempting to subdue. His PC, by itself, is […]

A short note on the Python Virtual En...

In this post we will discuss the concept of a Virtual Environment in Python. We will discuss the following topics: What is a Virtual Environment (VE) Setting up a VE Activation of a VE Installation of packages within the VE Deactivation of a VE Removal of a VE What is a virtual environment? A Python […]

The Agave Platform

agave.prod

A common task for ACI facilitators is assisting researchers with deploying or getting their software packages to run on the local or national resources and working with the job scheduler.  For the most part the reality of using HPC and HTC resources requires getting into the command line, which many new graduate students and post-docs […]

On Explaining Facilitation

hqdefault

There are times in life that it’s OK when you’re not sure what to say. To feel clueless (somewhat), and feel comfort in the newness of realized ignorance. To savor the moment. To look at your prior frame of reference, challenge your own assumptions, and then build a response from knowledge and experience that you […]

Learning the Facilitation Ropes

Learning the Facilitation Ropes

My name is Cesar Sul and I’m a relatively new ACI-REF at USC’s Center for High-Performance Computing. My introduction to facilitation began when one of our researchers started using our login nodes to run their research software. This was an excellent first case because it helped me learn about the rules and layout of our […]
