Hi team
Below are the details :
Using 40 lustre docker clients running on 4 x Dell R750 with each lustre docker
client running the below mentioned command
${xfersize} = ${blksize}
${blksize} = 128M, 64M, 32M, 16M, 8M, 4M, 2M, 1M
mpirun -hostfile nodefile --map-by node -np 16 /usr/local/bin/ior -a POSIX
--posix.odirect -v -i 50 -g -F -e -k -o /mnt/beegfs/test.ior
I think the problem is pretty clear right here - you are using BeeGFS for your
testing, not Lustre... :-)
-r -t ${xfersize} -b ${blksize} -O
summaryFile=./${TESTDIR}/iorresult_SeqWrite_p${numthreads}_bs${blksize}_tf${xfersize}.json,summaryFormat=JSON

please let me know what is the bottleneck in the above setup ?
Also if you need more info , will be provide it right away .
Cheers, Andreas
