Introduction

The XSEDE12 Student Programming Contest is a competitive programming event which will take place as part of the XSEDE12 Conference in Chicago, IL. Teams consisting of up to five students (high school, undergraduate, and/or graduate students) will be given eight to twelve problems from various scientific problem domain areas. To accommodate travel impediments, at least one team member is required to be physically present at XSEDE12, since all program development, testing, and deployment are restricted to the on-site computational resources. The contest will be based on the LittleFe cluster platform (http://LittleFe.net) and the Bootable Cluster CD software stack (http://BCCD.net). Contestants are encouraged to familiarize themselves with them before the contest.

Problem descriptions will be released one week prior to the on-site competition. Full problem descriptions and data sets will only be accessible to the teams on the day of the actual event. Students will have the bulk of the day, from 8:00 am until 5:00 pm, to submit code and solutions to as many problems as they choose. Part of the judging criteria will involve documentation of the team's activities. Each team will keep an engineering journal using electronic lab notebooks provided by the contest organizers.

Team Composition

A team consists of up to five students from recognized high school, undergraduate, and/or graduate degree programs. Faculty, and other coaches not part of the student team, are encouraged to mentor students up to, and including, release of the problem descriptions; but should have no involvement with the students on any aspect of the actual competition once the full problem details are released on the day of the event.

Hardware/Software Environments

Every team will be provided access to identical computational resources, a LittleFe v4 unit running the BCCD. Teams may not share resources. Team members may use their own laptops and the contest organizers remote computational resources if they request access to them. Team members will be able to install software on the LittleFe/BCCD unit during the contest.

High Level Description of Problems

Folding, but not your laundry

This problem is based on the processes and chemistry used by chains of amino acids to "fold" into proteins. Students will design a parallel algorithm considering chains of hydrophobic and polar protein elements.

Secret message

Encrypting and decrypting messages has been a long-standing use of a supercomputer of the day. While not a state secret cipher, this problem provides a message in a message in a message to uncover. The moral of the story is while there is a well-established place for high-level, highly-abstracted languages, algorithmic and performance issues may sometimes dictate other solutions.

This problem challenges you to discover algorithm(s) to simplify and solve a well defined logic puzzle, given that for a contest lasting only a few hours, a brute force algorithm could take days of run-time to complete.

Measure twice, cut once

In our constantly-evolving, many-core world, the task of load balancing is taking on more and more importance, as is the algorithmic load balancing of computational resources done within the parallel codes that computational scientists have written to implement their mathematical models. This problem offers students the opportunity to develop their algorithm for making load balancing decisions in the universe of hybrid computing, by deciding which tasks will be run together in shared memory mode, communicating between groups using message passing.

Repulsive gravity

Problems involving a large number of objects where everything interacts with everything else is found throughout science, from the very small to the very large and a lot in between. This class of problems is called an n-body problem.

Neurotoxin lab

There is a neurotoxin outbreak in an underground laboratory. The scientists inside are completely unprepared for this type of epidemic so their best bet is to get out as fast as possible. The only way out of the lab is through the escape elevators (they’re too high-tech for stairs). This will involve random walking (or running in this case), probability, and spread of poisonous gas.

Quasicrystals

Quasicrystals can be modeled as tilings of two dimensional space. The cardinality of the set of possible tilings, ie the size of state-space, is directly related to the entropy of the crystal. Consequently, the problem of counting the number of tilings of 2-D space with a fixed number of shapes of tiles is as important as it is difficult. Solving the problem requires the application of numerical techniques of discrete math in a physics/materials science context.

Has it cooled down yet?

Simulated Annealing is used in function minimization as a method of finding the global minimum for problems with many free parameters and many local minima.

How fast can you run?

Often the best way to compare two or more computational resources is to analyze how quickly and efficiently they can each solve a given problem. Some of these applications give better light into the resource's performance than others. Be prepared to use some common benchmarking tools.

Safe flying

If you did the air traffic analysis problem, you would see that the data leave a lot to be desired. One way to “fix” the data is to create your own by simulation. This problem is the basis for the real air traffic management systems used in Europe. The USA is still mired in old manual technology. The object here will be to simulate the air traffic in a 2-D square sector.

GFCUDA

General Purpose Graphical Processing Units (GPGPUs) are developing into a powerful and efficient computing platform. They are especially suited for data-processing applications, many of which can be modeled as matrix operations. In some cases, it can be advantageous to perform operations using groups, rings, or fields other than the integers or reals. Solving this problem requires implementing matrix operations over a Galois field on CUDA-enabled GPGPUs.

Evaluation Criteria

The following factors will be taken into consideration in ranking and awarding team honors:
