<dd><p>
Specify databse filename in filename: .
Specify backup of database file in backup: .
check span: specifies time span of calculating average and standard deviation.
</p></dd>
<dt><span class="term">errlog</span></dt>
<dd><p>
This commands prints error messsages in the file specified by errlog: .
All error messages are also written in the database.
If you don't need to error log file, this parameter can be omitted.
</p></dd>
<dt><span class="term">authentication</span></dt>
<dd><p>
Specify authentication types of performance measuring.
Authentication types are sharedsecret, gsi_auth and gsi.
Performance test is executed on all specified types.
</p></dd>
<dt><span class="term">gfarm2fs_mountpoint</span></dt>
<dd><p>
Specify gfarm2fs mount point.
When start testing, this command mounts all gfarm2fs mount point automatically. At the end of testing, unmounted automatically.
When changing authenticaion type, remounted automatically.

Specify parallel test patterns.
At first, specify group name that is a sinbol of parallel testing.
Group name must be uniq in all parallel testing (includes parallel-autoreplica).
Specify remote host in rhost: . This command uses ssh for executing command.
type: specifies one of read, write, replica. These types corresponds to gfperf-parallel-read, gfperf-parallel-write, gfperf-parallel-replica.
