- Hafizi Jalil of MYREN joined the meeting. He introduced himself. He has been at MYREN for 1.5 yearsyears. He maintains He maintains development for the MYREN network. He has PingER installations at Cyberjaya and UNIMAS. He has more machines, currently running perfSONAR at UMP,UTM,UM and another site. This week he will install PingER and the traceroute servers on these machines. A goal would be to compare and contrast the benefits of perfSONAR and PingER.
- Anjum and Raja have been working on a paper on Geolocation as developed for TULIP. Using an exponential relation between the Directivity (Alpha) and RTT for Pakistan the accuracy is ~ 18Km. Now Raja needs to run for Europe and the US. Meanwhile Raja has got a job and has less time to work on this so it was stalled. Les contacted Raja and Raja agrees it is important to finish the measurements and the paper, and will endeavor to do so. Anjum is currently working on another paper. Once he finished finishes that, If Raja didn’t find time to complete the results, he will try to see if he can take over and run the code hishim-self.
- Anjum's contract has been extended for 1 year
- Saqib's contract expired last month, he is back in Pakistan
- The 2015 ICFA/SCIC report is completed. It is available at http://www.slac.stanford.edu/xorg/icfa/icfa-net-paper-jan15/report-jan15.docx
- Hafizi Jalil will send Les his email address. Les will ask Badrul to add it to the pinger-my email list.
- Johari will add Ibrahim to the PingER contacts list. Done 2/5/2015
Johari has got the OK from the conference organizing committee to hold a colocated PingER/BigData workshop on August 3rd the day before the CITA 2015 (see http://www.cita.my/ an International Conference 4th - 6th August 2015, on transforming Big Data into Knowledge. Johari will provide relevant information to Bebo. Bebo will be able to make a presentation. Also Ridzuan or Ibrahim or Renan have interest in submitting a full paper by March 2nd 2015.

They are now preparing a test plan (like a small benchmark) to be used on all alternatives so that we can compare the results accordingly.
Les will contact Maria Luiza Campos of UFRJ (now on a one year leave of absence in Italy) to see if we can repeat the visit of Renan with a new student.
Les has requested (in January) Renan to provide an estimate of how DF bloats the data. Renan/Christiane are looking at this. Renan's pointed out "Finding RDF data size in bytes is not simple because it depends on which Triple Store will be used and how each triple is physically stored. One may store triples as plain texts, other may do as compressed data in specific formats, which would be much smaller."Once we have the number of PingER triples and how much the used Triple Store needs (in bytes) to store a known number of general triples, we may estimate PingER RDF data size.". Requested an update by email to Cristiane & Renan 2/4/2015.
