----

S3aSim is a sequence similarity search algorithm framework for testing and evaluating various I/O strategies using MPI-IO.

===== Usage =====
Let Makefile point to your MPI installation and make. There are some parameters to control the benchmark. Get a list by runing <code>mpirun -np 1 s3asim-test -h</code>

===== Example Output =====
For example runnning with default parameters ''mpirun -np 4 s3asim-test -q 10 -Q 1000 -d 10 -D 1000 -m 10 -M 1000 -p 1'' results in the following output
