<p>OK, to answer my own question.</p>
<p><br>
</p>
<p>First of all, inspect.lua from here is helpful:</p>
<p><br>
</p>
<p><a href="https://raw.githubusercontent.com/kikito/inspect.lua/master/inspect.lua" class="OWAAutoLink" id="LPlnk405418" previewremoved="true">https://raw.githubusercontent.com/kikito/inspect.lua/master/inspect.lua</a><br>
</p>
<p><br>
</p>
<p>You can then do the following in your job_submit.lua</p>
<p><br>
</p>
<p></p>
<div>package.path = package.path .. ';/etc/slurm/?.lua'</div>
<div><span style="font-size: 12pt;">local inspect = require("inspect")</span><br>
</div>
<br>
<p></p>
<p></p>
<div>function slurm_job_submit(job_desc, part_list, submit_uid)</div>
<div><span style="font-size: 12pt;"> slurm.log_user(inspect(slurm))</span><br>
</div>
<div> return slurm.SUCCESS</div>
<div>end</div>
<div><br>
</div>
<div>which might tell you the following on an srun:</div>
<div><br>
</div>
<div>
<div>srun: reservations = {</div>
<div>srun: root_1 = {</div>
<div>srun: <metatable> = {</div>
<div>srun: __index = <function 18>,</div>
<div>srun: _resv_ptr = <userdata 8></div>
<div>srun: }</div>
<div>srun: }</div>
<div>srun: },</div>
<br>
</div>
<div>From there on you can do</div>
<div><br>
</div>
<div>
<div> for a, b in pairs(slurm.reservations) do</div>
<div> slurm.log_user("a = %s", inspect(a))</div>
<div> slurm.log_user("b = %s", inspect(b))</div>
<div> slurm.log_user("--")</div>
<div> end</div>
<br>
</div>
<div>and get</div>
<div><br>
</div>
<div>
<div>srun: a = "root_1"</div>
<div>srun: b = {</div>
<div>srun: <metatable> = {</div>
<div>srun: __index = <function 1>,</div>
<div>srun: _resv_ptr = <userdata 1></div>
<div>srun: }</div>
<div>srun: }</div>
<div>srun: --</div>
<br>
</div>
<div>Aaaand now, you can -- obviously, more or less -- look here for the field names:</div>
<div><br>
</div>
<div><a href="https://github.com/SchedMD/slurm/blob/master/src/plugins/job_submit/lua/job_submit_lua.c#L236" class="OWAAutoLink" id="LPlnk591191" previewremoved="true">https://github.com/SchedMD/slurm/blob/master/src/plugins/job_submit/lua/job_submit_lua.c#L236</a><br>
</div>
<div><br>
</div>
<div>E.g,</div>
<div><br>
</div>
<div>
<div> for a, b in pairs(slurm.reservations) do</div>
<div> slurm.log_user("i = %s", inspect(a))</div>
<div> slurm.log_user(inspect(b.start_time))</div>
<div> slurm.log_user("--")</div>
<div> end</div>
<br>
</div>
<div>might print</div>
<div><br>
</div>
<div>
<div>srun: i = "root_1"</div>
<div>srun: 1630598400</div>
<div>srun: --</div>
<br>
</div>
<div>Maybe that's useful for someone.</div>
<div><br>

<div>Hi,<br>
<br>
I have trouble finding examples for job_submit.lua code that uses the global Slurm reservations. I want to adjust the maximal running time of jobs with respect to the closest reservation flagged as "maintenance". However, I cannot find any job_submit.lua coda
that accesses the Slurm reservations code.<br>
<br>
Is it possible to access this information from Lua?<br>
<br>
Best wishes,<br>
Manuel<br>
