BWA Benchmark (SBC)

Using BWA from https://github.com/smikkelsendk/bwa-for-arm/tree/master/bin (with NEON)

Dataset:

• Retrieve https://files.subsecret.dk/benchmark/GCF_000005845.2_ASM584v2_genomic.fna.gz
• Retrieve (normal size benchmark) https://files.subsecret.dk/benchmark/ecolireads.fastq.gz

• Run ./bwa index GCF_000005845.2_ASM584v2_genomic.fna.gz
• 1 thread benchmark
  • ./bwa aln GCF_000005845.2_ASM584v2_genomic.fna.gz ecolireads.fastq.gz > /dev/null
• 4 threads benchmark
  • ./bwa aln -t4 GCF_000005845.2_ASM584v2_genomic.fna.gz ecolireads.fastq.gz > /dev/null

Run on Android:

• Enable USB Debugging on device (https://www.embarcadero.com/starthere/xe5/mobdevsetup/android/en/enabling_usb_debugging_on_an_android_device.html)
• Download Android Platform tools: https://developer.android.com/studio/releases/platform-tools
• run

adb push BWA-EXECUTABLE /data/local/tmp
adb push GCF_000005845.2_ASM584v2_genomic.fna.gz /data/local/tmp
adb push ecolireads.fastq.gz /data/local/tmp

• then run

adb shell

You can now generate index and run bwa from directory /data/local/tmp
