 How big is the measured performance difference?

Each chart bar shows how many times more Time or how many times more Memory one unidentified ↓ regex-dna program used, compared to the program that used least Time or the program that used least Memory.

 regex-dna benchmark ~50MB N=5,000,000

This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ~ CPU Load.

Compare how much Memory the regex-dna programs used - sort Memory KB. Compare how much Code the programs used - sort Code B

Column × shows how many times more each program used compared to the program that used least.

 regex-dna benchmark : Match DNA 8-mers and substitute nucleotides for IUB codes

diff program output for this 100KB input file (generated with the fasta program N = 10000) with this output file to check your program is correct before contributing.

We use FASTA files generated by the fasta benchmark as input for this benchmark. Note: the file may include both lowercase and uppercase codes.

Each program should

• read all of a redirected FASTA format file from stdin, and record the sequence length
• use the same simple regex pattern match-replace to remove FASTA sequence descriptions and all linefeed characters, and record the sequence length
• use the same simple regex patterns, representing DNA 8-mers and their reverse complement (with a wildcard in one position), and (one pattern at a time) count matches in the redirected file
• write the regex pattern and count
• use the same simple regex patterns to make IUB code alternatives explicit, and (one pattern at a time) match-replace the pattern in the redirect file, and record the sequence length
• write the 3 recorded sequence lengths
