clone

git clone --recursive git@github.com:SonglinLife/SSD_BASED_PLAN.git 

compile

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --target SSD_Based_Plan -j8

use

./SSD_Based_Plan dim nd index data_type gp_file thread_num LDG_times 0 DEBUG blocksize 

dim vector dim, like 128

nd total vector number, like 1000000

index diskann index, like ./index/BIGANN_R48_disk.index

data_type vector type , float or uint8. int8 is equal to uint8, just use uint8

gp_file the partition file name

thread_num thread number

LDG_times the algorithm will execute , set 0 will output unpartitioned result

0 set it 0

DEBUG see DEBUG message, set it 0 for no debug

blocksize set 1, the parition block size would be 4KB, set 2 would be 8KB, and so on

use like

./SSD_Based_Plan 96 10000000 /data/wsl/diskann_re/build/tests/index/DEEP_10M_R48_L128_B0.225_disk.index_cp float ./gpfile/deep_10m_r48_rb1 64 16 0 1 1
