Dear Peter,
the scripts running on your remote system should generate LML files
for jobs and nodes. You can look into these files following the
instructions given at
https://wiki.eclipse.org/PTP/System_Monitoring_FAQ#Q:_How_do_I_debug_the_server_part_of_PTP.27s_system_monitoring_capability.3F
Jobs are mapped to the nodes through the following procedure:
A running job should have a nodelist or vnodelist attribute. Here is
an example for a job on a cluster:
<info oid="j000116" type="short">
<data key="name" value="my job"/>
<data key="owner" value="karbach"/>
<data key="totalcores" value="8"/>
<data key="nodelist"
value="(jj13c41,7)(jj13c41,6)(jj13c41,5)(jj13c41,4)(jj13c41,3)(jj13c41,2)(jj13c41,1)(jj13c41,0)"/>
<data key="group" value="unknown"/>
<data key="state" value="Running"/>
<data key="ppn" value="8"/>
<data key="queuedate" value="Sun Jun 2 16:03:21 2013"/>
<data key="queue" value="jsc"/>
<data key="spec" value="1:ppn=8"/>
<data key="dispatchdate" value="Tue Jun 4 05:47:43 2013"/>
<data key="status" value="RUNNING"/>
<data key="step" value="2696094.jj28b01"/>
<data key="totaltasks" value="8"/>
</info>
The nodelist attribute contains one entry for each used core. In the
above example the job uses the cores 0 to 7 on the node jj13c41. Thus,
the nodelist attribute has the form (<nodename>,core-id)*
The vnodelist is a shorter form, which only lists how many cores are
used by each node. For this example the equivalent vnodelist attribute
would be "(jj13c41,8)".
When you concatinate the mask attributes in your nodedisplay layout
(in your example "0xFF0100%01d%01x"), you have to be able to generate
all node names by using this format string in a "printf" command.
Unfortunately, the hexadecimal format is not supported. To use
hexadecimal numbers, replace mask="%01x" with
map="0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f".
These node names need to be identical to the node names listed in the
nodes LML file. E.g. for the cluster above the nodes LML file contains
the following information for node jj13c41:
<object id="nd002177" name="jj13c41" type="node"/>
...
<info oid="nd002177" type="short">
<data key="availmem" value="23498124kb"/>
<data key="id" value="jj13c41"/>
<data key="ncores" value="16"/>
<data key="physmem" value="24732484kb"/>
<data key="state" value="Idle"/>
</info>
The mask/map attributes in your nodedisplay layout are used to
generate regular expressions. LML_da can use them to extract the IDs
on each level from the actual node name in order to map a node to your
layout.
In addition to the replacement of the hexadecimal mask with the map
attribute, you also need to add a core-level element, defining how
many cores are configured in each node. LML_da currently always
requires the lowest level to look like the following:
<el3 tagname="core" min="0" max="15" mask="-c%02d"></el3>
Note that the mask attribute cannot be changed here. What you should
adjust are the min/max attributes depending on how many cores are
available in each node.
I hope that helps.
Best regards,
Carsten

Hi,
In order to add monitoring feature to Eclipse PTP on “K” computer I am
working on a customised LML-layout. For tests I use a smaller
sibling of
“K” named “FX10”.
I customised the perl scripts and layout description file
(samples/layout_default_PJM.xml), and now in the monitoring perspective
I can see a table with the jobs running on the computer. Nodes layout
that I created with nodedisplaylayout tag is displayed correctly.
What I can’t figure out is how I can map jobs to the nodes layout.
There
is information on the nodes used by every job in the jobs table,
but I’m
not sure if its format is correct.
Here is what I see:
Job 75612 is not displayed on the nodes layout.
In temporary files directory in datastep_LML2LML.xml file I have:
<nodedisplay id="nd_1" title="system: fx02p08">
<scheme>
<el1 tagname="chassis" min="0" max="6" mask="0xFF0100%01d">
<el2 tagname="node" min="0" max="16" mask="%01x">
</el2>
</el1>
</scheme>
<data>
<el1 oid="empty" min="0" max="6">
</el1>
</data>
</nodedisplay>
<data> is empty and so no job is displayed in nodes layout.
By the way, nodes are numerated with hexadecimal numbers. Is it OK to
use mask “%01x” ?
Kind regards,
Peter

Dear Peter,
thanks for the hint on the broken link. It was moved to
http://llview.fz-juelich.de/LML/OnlineDocumentation/lmldoc.html. I
have
updated the documentation page with the new link. On the LML
documentation page you can find a section about LML layout files,
which
is located at
http://llview.fz-juelich.de/LML/OnlineDocumentation/layouts.html.
There are also some layout examples integrated into PTP. You can find
them at
http://git.eclipse.org/c/ptp/org.eclipse.ptp.git/tree/rms/org.eclipse.ptp.rm.jaxb.contrib/data.
E.g. take a look at the configuration files
de.fz-juelich.judge.torque.batch.xml,
de.fz-juelich.juqueen.ll_bg.xml or
de.fz-juelich.juropa.torque.batch.xml. They all contain <monitor-data>
elements, which represent the layout definitions for each site.
See also
https://wiki.eclipse.org/images/7/7e/Carsten-Karbach-31july2013-Slides.pdf
for an introduction to creating your own monitoring layouts.
Regarding your first question: A summary on the monitoring
architecture
is given in the presentation here:
https://wiki.eclipse.org/images/d/d0/PTPUserDev2012_Monitoring_Karbach_Frings.pdf.
When you need to develop your own batch system adapter, you basically
have to write scripts for gathering three types of data: jobs,
nodes and
global system information. You have to write one script for each of
these types, where each script generates an LML file. All subsequent
steps of LML_da should be handled automatically. Find examples for
these
scripts for all supported batch systems at
http://git.eclipse.org/c/ptp/org.eclipse.ptp.git/tree/rms/org.eclipse.ptp.rm.lml.da/rms.
Best regards,
Carsten

Hi,
I work on adopting Eclipse PTP to “K” computer and its PJM batch
system
made by Fujitsu. I have a basic job running and profiling with TAU
features working. Now I'm working on monitoring.
I have very basic understanding of workflow and LML. Where can I find
specifications and examples of what output files should look like on
every step of the workflow? I also need instructions on creating a
layout definition file.
There is a link on wiki.eclipse.org/PTP/designs/scalability
<http://wiki.eclipse.org/PTP/designs/scalability> to LML
specification.
Unfortunately http://llview.zam.kfa-juelich.de site is not working.
