SC14 Intel Parallel Universe Computing Challenge: The Squad fails in the semi-final

All good things must end. In a heroic battle the Gaussian Elimination Squad was beaten by the “Brilliant Dummies” from Seoul University. We were quite a bit ahead after the trivia round, but the coding challenge was a real neck-breaker. We couldn’t even find the spot where one should start leveraging parallelism, and we ended up with a disappointing speedup of just above 1.

The Squad congratulates the Korean team, it was a great fight! We hope to return next year to SC15 in Austin, Texas.
