Hi all,

please wait a bit before checking out the svn.

I have overlooked that I have hidden svn files in the directories (because I copied whole directories before) so when committing the svn overwrote _other_ directories (!). Mohammad is trying to fix it right now.

apologies, Soeren

Dear all,

In the test job JDLs please make sure they save output (if the case) to a directory writable by the production user 'pbarprod',
even if you try the job as yourself or as 'pbartest'. We will use 'pbarprod' for the data challenge next week.

Of course, I will doublecheck the JDLs proposed for the DC. Smile

Hi,

I installed a 32 bit and a 64 bit version (binaries with libs only) of the UrQMDSmm eventgenerator on the Grid, compiled against root5.18 (which version is the most actual one for the external packages). It seems to work for the sites I could test it on. To test it on any site:

Installation (presently already instaled at KVI,GSI,Juelich,Dubna,Bucharest)
---------------------------------------------------------
packman install pbarprod@urqmd::r2008

test scripts
---------
/panda/user/p/pbarprod/bin/testurqmd.sh
/panda/user/p/pbarprod/jdl/testurqmd.jdl

i.e.

submit /panda/user/p/pbarprod/jdl/testurqmd.jdl <id> <momentum> <nrofevents>

will do the job with the output @

/panda/user/p/pbarprod/jgm/urqmd/run<id>/..

Dear colleagues,

I prepared a schedule for the days remaining until the start of the Data Challenge (summarizing what has been discussed so far). It is displayed on http://panda-wiki.gsi.de/cgi-bin/view/Computing/DataChallenge1#Schedule. Inputs, comments are highly appreciated. I will try to coordinate the final steps to be able to run the jobs on 17.-19. April.

The packages will have to be finalized very soon, installed and testd on the sites, and we have to decide on the macros to run. As a first step I would like to grasp the current status. Could you please help with this?

* Packages:
Can you Soeren, please summarize the status of the software. What is the current status, what is left to do?

* Macros:
The latest proposal by Soeren was (or did I miss something?)

--------------------------------------------
stt
===
root -b runsim.C"(nEvents,pT)"
root -b rundigi.C
root -b runreco.C

pT=30,40,50,...100 MeV/c
pT=100,200,300,...,1000 MeV/c
pT=1,2,3,...,7.5 GeV/c
10,000,000 events each

tpc
===
root -b run_sim_tpcmvd.C"(nEvents,pT)"
root -b run_rectrack_tpcmvd.C

pT=30,40,50,...100 MeV/c
pT=100,200,300,...,1000 MeV/c
pT=1,2,3,...,7.5 GeV/c
10,000,000 events each

dpm
===
Events and beam momenta for dpm will be proposed tomorrow
--------------------------------------------

Soeren, do you want to update?

What about the UrQMD and the fast sim macros Johan has already installed and tested on the grid?

Could you, Soeren and Johan, please try to make a concise list of possible simulations to run, based on the packages which will be available for the DC01?

Can you Johan please summarize the status of the macros and the jdls. Examples for UrQMD and the fast sim are obviously ready. What about the other simulations (stt, tps, dpm)? Will you be able to take care of this?

* Storage:
One event is 250 Bytes (the number was given by Soeren). Is this true for any of the prposed simulations (UrQMD?)? If yes then we most probably have far enough storage capacity (1TB ~ 4.E9 events).

* CPU time
Can somone give a (rough) estimate of the CPU time used per event? This number would help to decide on the number of events to submit (per job, total).

Cheers,

Paul

Hi all,

Once we have the most recent external packages installed, I will upload the most recent pandaroot revision including the macros which are proposed for the DC. This I can do during the weekend. I will also try to initiate a remote installation to all the other sites and report back where things went wrong (using the template on the wiki site).

Kind wishes,

Hi Paul and all,

Quote:

* Packages:

I can only comment on PandaRoot itself.

There were only 2 issues left.

1.) if riemannfit is on, then lhetrack cannot run.
This is more complicated and will need time to solve.
However, lhetrack is global (has tpc and mvd),
riemannfit is local (tpc only) in our understanding
So we decided to switch riemannfit off for the DC
(I am sorry to Sebastian and Tobias for this,
but we just have to make a decision just due to time pressure).

2.) include mvd into the tpc macros
(and so run the _global_ tracking for both mvd and tpc).
This was solved today by Stefano with help of Tobias and Ralf.
He checked it in.

-> this means:

rev---- is final for tpc, stt, dpm.

As the UrQMD code is not in the svn repository, this means:

rev2480 can be regarded as the PandaRoot version for the DC
(note:revised by Soeren on Friday Apr 11 15:37)

(only exception: if there is a last minute bug fix)

THIS MEANS:

(please read and enjoy)

we will run global(!) tracking for tpc digis(!) and mvd digis(!)

*

Quote:

[...]
Soeren, do you want to update?

Yes, I would like to propose the beam momenta for the dpm simulations.
(these are input parameters for the bash scripts prepared by Johan).

[p_beam / GeV/c][what for?]

0.739 (for PhiPhi at 2.000 GeV)
2.202 (for PhiPhi at 2.500 GeV)
4.064 (for J/Psi 3.096 GeV)
6.234 (for Psi' 3.686 GeV)
6.571 (for Psi 3.770 GeV)
6.991 (for X 3.872 GeV)
7.277 (for Y 3.940 GeV)
7.705 (for Psi 4.040 GeV)
8.685 (for Y 4.260 GeV)
11.917 (for D*_sJ D_s 4.9178 GeV)
15.000 (for Drell-Yan)

I propose 10,000,000 events for each.

Quote:

Paul, can you specify your question a bit?

Because all the mentioned above is the list.

1. tpc sim and reco (see macros, nEvents, pT above)
2. stt sim and reco (see macros, nEvents, pT above)
3. dpm event generation
(bash scripts by Johan, see p_beam, nEvents just a few lines above)
4. UrQMD event generation
(see separate posting by Johan)

This is it.

Paul, please be careful!!!

for stt and tpc sim and reco, it is much more!!!

It is the numbers in my last posting.

for tpc 56.5 kB=kiloBytes per event

for stt 17.3 kB=kiloBytes per event

plus an offset for each run (the "zero" events case).

Hi everyone,

just to let everyone know ...

I know we fixed the PandaRoot revision, but if there is a chance to wait for a few hours, please do so ...

Mohammad and Stefano are working on some more things.

The idea is to switch on a few more detectors (incl. EMC reco -> clusters for later track matching for both tpc and stt) and Mohammad is just writing a interface to call dpm from a root macro (so that the bash scripts are not needed). We also discussed to run dpm full sim (Geant3, Geant4) instead of only dpm event generation.

So, -> a few nice things!

Anyway, if there is any chance that you wait for a few hours, this would be great ...

cheers, Soeren

Hi everyone

I installed the latest version of the external packages which is called panda_extern::apr08. This is the version from march with some small changes for the grid. Installation at GSI works fine, so i didn't expect problems with the other sites.

I will prepare everything for the installation of pandaroot.

final PandaRoot for DC [message #6378 is a reply to message #6370]

Hi all,

we proudly present

PandaRoot rev2480
-> this will now be the version for the DC.

/macro/dc1/stt

new: contains emc digis (clusters), too
for track matching

note: there is no stt rundigi.C macro anymore
-> it is not integrated into the runreco.C macro
(as it is also for tpc)

/macro/dc1/tpc

new: contains emc digis (clusters), too
for track matching

track visualization is now switched off
-> saves disk space

/macro/dc1/full

THIS IS NOW THE DPM !

(it means, basically no basf script necessary anymore,
but if you want to run the DPMGen executable for some
reason, this also still works).

new: we do not only event generation but even Geant3.

all detectors.

pT and nEvents are now parameters of the macro.

disk space: 105 kB per 1 event

(so not anymore only 250 bytes/event!)

CPU time: ~1 sec per 1 event.

note: there is no option for the seed.
Mohammad says that it is taken from the date.

NOTE! pgenerators/DpmEvtGen needs to be compiled on each site!
(this is not part of the cbuild)
but Florian will prepare it for the packages.

all is tested and works.

additional note:

all macros contain new newest mvd and newest forward emc geometry!

(they were generated with different external packages,
but Stefano fixed it).

Thanks everyone for debugging etc. (Mohammad, Stefano, Ola, Tobias, Florian, ...)

I think the phone companies will be very happy about today's accounting bill.

Hallo Johan,

Quote:

gRandom->SetSeed(<my favorite seednumber>);

Not really, because dpm do not know anything about root and gRandom.

in the PndDpmDirect, the seed is set using:

 Long_t Time = time(NULL);
int a = Time/100000;
seed = Time - a*100000 + a/100000.;

which is the same as it was in the executable, except that it is changed for each event, so each call to the next event will set the seed again. It is simple but I think it is enough, with the executable you set the seed once for all events and here you change it for each event! Any way if you think this is not enough we can change it and take the seed for example from gRandom, this should be straight forward!

regards

Mohammad

Hi Mohammad and all others,

Thanks for your clear answer, Mohammad. I just wonder what the probability is that two (or more) jobs will start a DPM event with the same seed. Twisted Evil

Twisted Evil

The "time(NULL)" instruction gives an output in precision of seconds, right? Hmmm, in that case it could actually be very likely. It might, therefore, be more safe to set it up it via gRandom, which one can more easily control from the "outside". Actually, is this the same for the box generator (as used for the other DC macros)?

Best wishes,

Johan

Hi,

The box generator uses gRandom, the code in PndDpmDirect was taken from the original DPM files! Anyway I change it now (rev. 2487) to use gRandom for setting the seed.

Dear all,

I put a list of jobs to run during the DC on the wiki http://panda-wiki.gsi.de/cgi-bin/view/Computing/DataChallenge1 and would like to ask you for your comments and suggestions.

The list contains all the proposed scripts and momenta. However it foresees to produce only 100'000 events per momentum and not the 10'000'000 as originally proposed.

There are:

- 240 stt splits a 10'000 events, each running for ~2h, producing 200 GB in total
- 240 tpc splits, 10'000, ~2h, ~200 GB
- 110 full splits, 10'000, ~9h, ~200 GB
- 100 urqmd splits, 10'000, ~1h, ~1 GB
- 1000 generic splits, -, ~10 sec, 10 MB

In total: ~2000h, 1 TB

The critical point I think will be the available CPU time and data transfer time.
Alternatively we could run only a few momenta with higher statistics.

Hi Paul,

great !!!
Can we make a guess concerning the needed bandwidth for inter site transfers ?
I mean, we have a certain amount of promised CPUs at a site.
This results in a certain amount of jobs and finally in a certain amount of produced output per time unit which needs to be transferred to certain places within a given time which results in a need bandwidth of X Mbs between sites.

Dear all,

for the upcoming data challenge:

please use

panda::gsi::virtual

and not

panda::gsi::file

the new SE is an xrootd cluster with significant more storage space than the old NFS mounted disk.

But both SEs are still operational, in case you want to access old files.

Cheers,

Kilian

I did re-register the scripts. They are now at PANDA::Vienna::file.

Dear colleagues,

The first PANDA grid Data Challenge, which was running since last Thursday morning is now finished. A brief summary of what has been happening in the past few days can be found at http://panda-wiki.gsi.de/cgi-bin/view/Computing/DataChallenge1#Results.

This DC was very helpful. We will have to analyze and evaluate the result. But I am sure, that the experience we gained will help to further improve the procedures, the system, and its operation.

Many thanks to all of you who have helped in the last days to get and keep the system running.

Best regards,

Paul

Hi Paul,

thanks a lot for the great work you did.
Why did you put the RUNNING distribution in the Wiki ?
If you put the DONE distribution it looks quite different. According to the DONE of last week in ML GSI computed about 50% of the jobs, while the other sites shared the other 50%. Ateneo contributed with almost 6%, which is great with 10 machines.
What was the main reason why the STT jobs did not work ?
Also in the full_dc quite some jobs seem to have failed. What was the main reason here ?
All in all we seem to have close to 50% error rate, which needs to be improved, somehow.

Cheers,

Kilian
