Pinger at SLAC
Added hosts over Xmas, now monitor 171 countries that contain 99.14% of the world's population. Monitor all countries with > 1M people except Central African Republic, Chad, Guinea-Bissau, North Korea.
Putting together annual report for PingER.
Looking at whether the incidence of Duplicate pings is reducing with time.
Bebo came up with a self funded researcher who is interested in communications. Les reviewed the information and sent information on a possible project to the researcher: I include the information below in case there is a self funded researcher/graduate student from Pakistan or Malaysia who is interested.
Dear Yu Su,
I would like to describe what we plan to do starting from Feb. 2015.
We have applied to the US Department of Energy (DoE) for a 9 month grant to further the design and implementation of a ultra-high performance parallel data transfer software for both LAN and WAN. Currently this effort will use the SLAC 10/100Gbit/sec network and the 100Gbps connections to our providers and the Internet. At present there are no plans to extend this to mobile networks. This will change in the future as mobile/wireless connection exceed Gbit/sec.
The software leverages high-performance backend storage (e.g. NVMe SSD devices aggregated using a parallel file system, e.g. IBM GPFS, Intel Lustre, Fraunhofer BeeGFS), cluster compute (provided by a cluster of commodity servers), and a multiple TCP stream approach to attain excellent out-of-box bandwidth utilization with minimum tuning over multiple network connections (e.g. four 10Gbps NICs per server). It's also aimed to achieve such good utilization regardless data set types: Large files, mixed-sized, or lots of small files (LOSF). Encryption for data in-transit is provided by SSL with optional perfect forward secrecy (PFS). The data transfers are managed using a US patent-pending protocol.
An earlier version of the software was demonstrated at Super Computing 2014 (SC14) in this past November.
We have 40Gbps and 10Gbps connected hosts at 2 data centers and 100Gbps between the sites.
We will start out with local transfers and later extend to long distance (trans-continental, inter-continental) links
Should the aforementioned grant be awarded, we will initially focus on the following four technical objectives:
1. Issue resolution, design refining and implementation tuning.
2. Implement missing features.
3. More extensive validation over 100Gbps networks.
4. More extensive storage scale-out validation
Once the above objectives are accomplished, we will enhance the software for long distance testing over transit links.
The work will involve writing scripts to automate measurements, statistical analysis of measured data, sophisticated configuration/tuning of TCP stacks, file systems, and network connections to achieve high performance. We are also looking at funding a graduate student (possibly from Pakistan). English is a probably a second language for this student so you will need a good command of the English language.
Completed putting together annual report for PingER.
Completed report on Duplicate pings
Please let us know if the above scope fits with your interest and goals.
