This code is an ongoing work in progress.
There are several options to build. MODE is an important variable
governing the type of build. The default is MODE=perf, see the
Makefile for more options. DEBUG=1 triggers a debug build (off by
default). CHECK_INVARIANTS=1 enables invariant checking. There are
two targets: the default target which builds the test suite, and
dbtest which builds the benchmark suite. Examples:
MODE=perf DEBUG=1 CHECK_INVARIANTS=1 make -j
MODE=perf make -j dbtest
Each different combination of MODE, DEBUG, and CHECK_INVARIANTS triggers
a unique output directory; for example, the first command above builds to
out-perf.debug.check.masstree.
Silo now uses Masstree by default as
the default index tree. To use the old tree, set MASSTREE=0.
To run the tests, simply invoke <outdir>/test with no arguments. To run the
benchmark suite, invoke <outdir>/benchmarks/dbtest. For now, look in
benchmarks/dbtest.cc for documentation on the command line arguments. An
example invocation for TPC-C is:
<outdir>/benchmarks/dbtest \
--verbose \
--bench tpcc \
--num-threads 28 \
--scale-factor 28 \
--runtime 30 \
--numa-memory 112G
To reproduce the graphs from the paper:
$ cd benchmarks
$ python runner.py /unused-dir <results-file-prefix>
If you set DRYRUN=True in runner.py, then you get to see all the
commands that would be issued by the benchmark script.
