August 12th: Testing Voltage on Modules and Instaling pXar

Module Testing

Many of the ROCs on the modules are not programmable. We measured the voltage in certain capacitors in each ROC to find more information about why they are not working, and also to determine if the damage is the same in all of them. We found that while all the ROCs yielded the correct voltage on VD (direct voltage(?)), most of them didn't show any voltage at CAD- or VDIGI. However, a few showed almost the same voltage for VD and CAD- and zero for VDIGI which could indicate that the two first are shorted.

pXar

The pXar source code is available in github at https://github.com/psi46/pxar.

The guide for it's installation, the dependencies and other shenanigans are detailed in the manaual located here: https://twiki.cern.ch/twiki/pub/CMS/Pxar/pxar-manual.pdf . I had to re-install ROOT since this software is necessary for pXar, so I will finish the installation some other time.

Stealth Susy

All the info on this project will be archived in this website: https://twiki.cern.ch/twiki/bin/view/Sandbox/StealthSUSYAnalysisLog

Getting started

I've used Daniel Guerrero's Sandbox ( https://twiki.cern.ch/twiki/bin/view/Sandbox/DanielGuerreroSandbox) as a guide to get started.

Kerberizing and signing in to FNAL account

After obtaining a FNAL account:

The easiest way I found was to install kerberos through Synaptic Package Manager. The necessary packages

• krb5-user
• krb5-config(*)

The package manager will show a prompt suggesting all the other necessary packages.

After this it is necessary to download the appropriate krb5.conf and sshd_config(*) files from

http://www.fnal.gov/docs/strongauth/krb5conf.html

and later saving them in the right directories by typing on the terminal:

• $ cp krb5.conf /etc/krb5.conf
• $ cp sshd_config /etc/ssh/sshd_config (*)

Finally to connect to the FNAL machine type:

• $ kinit user_name@FNALNOSPAMPLEASE.GOV
  • .- this will require the kerberos password to be entered
  • To make sure a ticket was crated do: $ klist
• $ ssh -XY user_name@cmslpc-sl5NOSPAMPLEASE.fnal.gov

(*) These steps might not be absolutely necessary

Re-Installing ROOT

I was having issues with some tasks on root, so I re-installed it following Daniel's guide found at:

CMSDAS

I'm following the exercises found here

https://twiki.cern.ch/twiki/bin/viewauth/CMS/WorkBookExercisesCMSDataAnalysisSchool

To follow this exercises I had to copy some scripts from lxplus5 to run them on my laptop, as the bandwidth was too slow. The first exercises I did in lplus5 and locally on my pc.

July 10th: Certificates

To view and manage my certificates I went here.

July 9th: Pre-Workshop Exercises

To find data in DAS either

• go to the website https://cmsweb.cern.ch/das/
• or install the command line tool as shown in https://cmsweb.cern.ch/das/faq and perform the search:
  • ./das_client.py --query="dataset= /SingleMu/Run2012A-recover-06Aug2012-v1/AOD | grep dataset.name" --format=plain

Also reviewed in this set

• Exercise 5 - EDM ( Event Data Model framework) standalone utilities - edmFileUtil, edmDumpEventContent, edmProvDump, edmEventSize
• Make a Physics Analysis ToolKit (PAT)Tuple (MC and Data sample)

July 8th: Intro & Pre-Workshop Exercises

Four fairly simple exercises were done on copying, editing, setup and finding data were performed. These are detailed here

Git

July 13th: Tutorial on Git

I found this tutorial to use Git. It is written in a "for dummies" manner but it seems pretty thorough and like a good place to start.

Unix

Run commands as terminal opens

Sometimes it's convenient to have the system run some commands automatically when the terminal is open. I used this to change the directory where the terminal opens at. To do this I modified the ~/.bashrc file

• $ gedit ~/.bashrc

Now I added the commands I wanted to run, e.g.

• $ cd Desktop

Copy files from remote computer

To copy a file a remote desktop I used

• scp user@remote_host:remote_file local_file

Modify Touchpad Beheaviour in Ubuntu

Modify what each tap, scroll or click does, use synclient.

Print output AND pipe to a file

time nice ./HT_data_full_V1 all_HT_data.list | tee runAug19.log
