Hi,
I need to simulate a workload of generating sequence
of files - some thing like creating photos.
where is my config:
[global]
create_on_open=1
unlink=1
filesize=70m
size=7000m
[pilatus-sec-write]
rw=write
openfiles=1
nrfiles=100
stonewall
I will expect that a combination of create_on_open and openfiles
will create one file at the time, nevertheless all files get
created at the same time.
Thanks in advance,
Tigran.

Try adding file_service_type=sequential to your job file.
Cheers,
Jeff

if you can't find a soln, try a for loop and create sections like these??:
[pilatus-sec-write_1]
rw=write
openfiles=1
nrfiles=1
stonewall
[pilatus-sec-write_2]
rw=write
openfiles=1
nrfiles=1
stonewall
[pilatus-sec-write_3]
rw=write
openfiles=1
nrfiles=1
stonewall
