#DESCRIPTION:ltp A-sync IO Stress IO tests # # aio-stress [-s size] [-r size] [-a size] [-d num] [-b num] # [-i num] [-t num] [-c num] [-C size] [-nxhlvOS ] # file1 [file2 ...] # -a size in KB at which to align buffers # -b max number of iocbs to give io_submit at once # -c number of io contexts per file # -C offset between contexts, default 2MB # -s size in MB of the test file(s), default 1024MB # -r record size in KB used for each io, default 64KB # -d number of pending aio requests for each file, default 64 # -i number of ios per file sent before switching # to the next file, default 8 # -O Use O_DIRECT (not available in 2.4 kernels), # -S Use O_SYNC for writes # -o add an operation to the list: write=0, read=1, # random write=2, random read=3. # repeat -o to specify multiple ops: -o 0 -o 1 etc. # -m shm use ipc shared memory for io buffers instead of malloc # -m shmfs mmap a file in /dev/shm for io buffers # -n no fsyncs between write stage and read stage # -l print io_submit latencies after each stage # -t number of threads to run # -v verification of bytes written # -x turn off thread stonewalling # -h this message # ADS1000 aio-stress -I500 -o2 -S -r4 $TMPDIR/file1 ADS1001 aio-stress -I500 -o2 -S -r8 $TMPDIR/file1 ADS1002 aio-stress -I500 -o2 -S -r16 $TMPDIR/file1 ADS1003 aio-stress -I500 -o2 -S -r32 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1004 aio-stress -I500 -o2 -S -r64 $TMPDIR/junkfile $TMPDIR/file2 ADS1005 aio-stress -I500 -o3 -S -r4 $TMPDIR/junkfile $TMPDIR/file2 ADS1006 aio-stress -I500 -o3 -S -r8 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1007 aio-stress -I500 -o3 -S -r16 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1008 aio-stress -I500 -o3 -S -r32 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file3 $TMPDIR/file4 ADS1009 aio-stress -I500 -o3 -S -r64 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file3 $TMPDIR/file4 ADS1010 aio-stress -I500 -o3 -S -r128 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file3 $TMPDIR/file4 ADS1011 aio-stress -I500 -o3 -S -r256 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 $TMPDIR/file7 $TMPDIR/file8 ADS1012 aio-stress -I500 -o3 -S -r512 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 $TMPDIR/file7 $TMPDIR/file8 ADS1013 aio-stress -I500 -o2 -O -r4 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 $TMPDIR/file7 $TMPDIR/file8 ADS1014 aio-stress -I500 -o2 -O -r8 $TMPDIR/file1 $TMPDIR/file2 ADS1015 aio-stress -I500 -o2 -O -r16 $TMPDIR/file1 $TMPDIR/file2 ADS1016 aio-stress -I500 -o2 -O -r32 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1017 aio-stress -I500 -o2 -O -r64 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1018 aio-stress -I500 -o3 -O -r4 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1019 aio-stress -I500 -o3 -O -r8 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1020 aio-stress -I500 -o3 -O -r16 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1021 aio-stress -I500 -o3 -O -r32 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1022 aio-stress -I500 -o3 -O -r64 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1023 aio-stress -I500 -o3 -O -r128 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1024 aio-stress -I500 -o3 -O -r256 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file4 $TMPDIR/file3 $TMPDIR/file5 $TMPDIR/file6 ADS1025 aio-stress -I500 -o3 -O -r512 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 ADS1026 aio-stress -I500 -o0 -S -r4 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 ADS1027 aio-stress -I500 -o0 -S -r8 $TMPDIR/file2 ADS1028 aio-stress -I500 -o0 -S -r16 $TMPDIR/file2 ADS1029 aio-stress -I500 -o0 -S -r32 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1030 aio-stress -I500 -o0 -S -r64 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1031 aio-stress -I500 -o1 -S -r4 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1032 aio-stress -I500 -o1 -S -r8 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1033 aio-stress -I500 -o1 -S -r16 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1034 aio-stress -I500 -o1 -S -r32 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1035 aio-stress -I500 -o1 -S -r64 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1036 aio-stress -I500 -o1 -S -r128 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1037 aio-stress -I500 -o1 -S -r256 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file4 $TMPDIR/file3 $TMPDIR/file5 $TMPDIR/file6 ADS1038 aio-stress -I500 -o1 -S -r512 -t8 -x $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 ADS1039 aio-stress -I500 -o1 -O -r4 -t8 -x $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 ADS1040 aio-stress -I500 -o1 -O -r8 -t2 -x $TMPDIR/junkfile $TMPDIR/file2 ADS1041 aio-stress -I500 -o1 -O -r16 -t2 -x $TMPDIR/junkfile $TMPDIR/file2 ADS1042 aio-stress -I500 -o1 -O -r32 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1043 aio-stress -I500 -o1 -O -r64 -t2 $TMPDIR/junkfile $TMPDIR/file2 ADS1044 aio-stress -I500 -o1 -O -r4 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1045 aio-stress -I500 -o1 -O -r8 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1046 aio-stress -I500 -o1 -O -r16 -t4 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 ADS1047 aio-stress -I500 -o1 -O -r32 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file4 $TMPDIR/file3 $TMPDIR/file5 $TMPDIR/file6 ADS1048 aio-stress -I500 -o1 -O -r64 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 ADS1049 aio-stress -I500 -o1 -O -r128 -t8 $TMPDIR/junkfile $TMPDIR/file2 $TMPDIR/file7 $TMPDIR/file8 $TMPDIR/file3 $TMPDIR/file4 $TMPDIR/file5 $TMPDIR/file6 ADS1050 aio-stress -I500 -o1 -O -r256 -t2 $TMPDIR/junkfile $TMPDIR/file2
