Test utility for benchmarking compression of test collections. Input format as: Document identifier data set Packaged by D. Lemire on April 3rd 2014 Based on data sets prepared by L. Boytsov The main data files are in a binary flat file format described simply as follows. They contain a sequence of 32-bit unsigned integers (written in little endian mode). These integers make up lists of integers. Each list starts with an integer indicating its length followed by the corresponding number of integers in sorted order. HOW TO BUILD (in-place make): 1. Export root path for the build (BitMagic root dir) run: > . ./bmenv.sh ( from the root directory dot is important!) OR just >PROJECT_DIR=`pwd`; export PROJECT_DIR 2. build using: make BMOPTFLAGS=-DBMAVX2OPT OR make BMOPTFLAGS=-DBMSSE42OPT OR make 2. HOW TO RUN To run this test you need to download or prepare benchmark files (integer sets) 2.1 Read the input set, create the output (bit-vector compressed format): ./bminv -c -u32in /gov2.sorted -bvout /gov2.sorted.bv 2.2 Run validation comparison to make sure there are no errors ./bminv -verify -u32in /gov2.sorted -bvin /gov2.sorted.bv Help: ./bminv -h
