Renan has contacted the admin (Vinicius) for the UFRJ PingER monitor, to see if it can be restored to a working state. Vinicius explained they went through infrastructure changes and there are some important hardware pieces missing, which is delaying the process. Vinicius explained that hopefully around mid-February they should have the necessary hardware so they can reinstall the systems and PingER program.
Renan has provided a 4 page Appendix on PingERLOD to the ICFA report. This is also available at PingER LOD OverviewRenan is testing Virtuoso which is free to see if it can overcome the slowness of the current PingERLOD. He plans to be done in the next 2 weeks. If this does not work we may need to look into a tool that costs moneystarted testing Virtuoso last weekend. He now has the data in an easily exchangeable format so he can transfer it from the earlier repository he was using (OWLIM) to the new one (Virtuoso). That is what he is trying to do this week: upload to the Virtuoso database. The main problem for me is that he can use only 2 hours a day to work, because of his job.
Renan is looking at submitting a paper or poster for a Big Data and Social Computing conference that will be held at Stanford: He is pretty sure he can argue that we have made nice contributions for social computing using (big) data handling technologies. He will discuss with his professor at Rio so she can help him with advice. Bebo will look has looked at the conference information and the deadline to verify its relevanceand believes a posters submission would be good. Renan will look into whether he can get financial assistance to attend.
It would be good if somebody else was able to work with Renan to move PingER LOD forward. However we think the performance issue has to be resolved first.

He has also made some modifications on the ontology of the project (under supervision of his professor in Rio) hence he will have to modify the code to load the data accordingly.

Raspberry Pi
A quick comparison of the performance of the two hosts (raspberry pi and regular UNIMAS host) without statistical quantification is available at https://confluence.slac.stanford.edu/display/IEPM/Comparison+of+PinGER+RTTs+from+UNIMAS+monitors+N4+and+RASPBERRY. A page has been created to compare the hardware spec between the pinger.unimas.my node (Intel architecture) and the pinger2.unimas.my node (Raspberry Pi ARM architecture), available from the unimas pinger website at http://pinger.unimas.my/pinger/hardware.php. There is a link to hardware.php in the Comparison+of+PinGER+RTTs+from+UNIMAS+monitors+N4+and+RASPBERRY web page.
