'Accomplished'
- Ahmed bought and successfully installed the Infiniband cards.
- Benchmark experiments were run for Infiniband.
Issues
- Ahmed's implementation of SDP doesn't support asynchronous calls.
- Ahmed couldn't run PCIe and Infiniband experiments from the same machine (library conflict between his SDP and Infiniband SDP)
- Time is tight for the IPDPS submission.
Next Steps
Ahmed will implement asynchronous call support in order to run his application-based evaluation and compare it to Infiniband.
I will register the paper's abstract to IPDPS over the weekend (deadline is Monday, Sept 24th).
Although the time is tight, Ahmed will try to finish his asynchronous calls support and the application-based evaluation by the end of next week. This gives us a couple of days to polish up the paper.

Abdullah tried to obtain HPC I/O logs off of the internet. When that was not possible, he tried a couple of benchmarks to to generate some I/O logs as a placeholder until we obtain logs from real HPC applications.
During a first meeting, we tried to analyze the data, e.g., to verify the Markov chain order using partial autocorrelation functions. I noticed the data was so fine-grained (time in nanoseconds and block size in KB). I asked Abdullah to work on the coarser representation of the log (e.g., 1 second and MBs).
