- Overview of CHPC, Aug 25, 1-2 p.m.
INSCC Auditorium (room 110)
Posted July 11th, 2016
Tangent was restored to service on July 15th. Jobs that were idle in the batch queue before the hardware issue are now running and users can now submit new jobs.
CHPC will be a satellite site for a new HPC workshop on Workflows to be held on August 9 and 10, 9am-3pm MDT each day. The location of the workshop is still to be determined, based on enrollment.

Watching Nanomaterials Assemble at CHPC
By Prof. Michael Grünwald, Department of Chemistry
My son and I like to build remote control cars. The path that leads from a disordered pile of plastic parts and metal screws to a ne race car is straightforward and fun: step after step, we collect the pieces that need to be assembled and put them together according to the instructions. In fact, this assembly strategy is the blueprint for much human building activity and applies almost generally to the con- struction of houses, machines, furniture (in particular the Swedish kind), and many other objects of our daily lives.
Large objects, that is. Building small things, as it turns out, requires a strikingly different approach. Consider, for in- stance, the “objects” illustrated in Figure 1: A porous crys- tal structure made from intricately arranged metal ions and organic molecules (a “metal-organic framework”), and an ordered arrangement of nanoparticles (a “superstructure”), which themselves consist of many thousands of atoms. These structures are examples of “nanomaterials”, objects that derive their unusual properties from their fascinating microscopic structure. Because of their large pores, metal- organic frameworks like the one in Figure 1a can be used to store hydrogen gas, lter CO2, or separate molecules by shape. Depending on the kinds of nanoparticles used, superstructures such as the one in Figure 1b can be used to alter the direction of light, or act as new kinds of solar cells.
