BWA Benchmark (ODROID C2,RPI3)

BWA Benchmark

BWA is a tool for mapping reads against a genome. This is nice for doing a non-synthetic benchmark, as meaningful work is done, and IO, Memory and CPU is all used.

BWA Setup instructions

• Retrieve https://sourceforge.net/projects/bio-bwa/files/bwa-0.6.2.tar.bz2/download
  • Patch the Makefile:
    • Add to DFLAGS: -std=gnu90 -D_NO_SSE2
