With the SciMark collection of C-based computational tests, LLVM's Clang 3.4 compiler was running measurably ahead of GCC 4.8.2 on the NVIDIA Jetson TK1 board with Tegra K1 quad-core ARM Cortex-A15 SoC.

The fast performance out of Clang for the Monte Carlo and Fast Fourier Transform sub-tests is what led to SciMark 2's high composite score for the LLVM-based compiler.

With the Sparse Matrix Multiply and Dense LU Matrix Factorization, the performance between Clang 3.4 and GCC 4.8.2 was very close.

Clang finished out the SciMark 2 tests with another win, this time for the Jacobi Successive Over-Relaxation sub-test.
