PCIe Project

• 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.

HPC Storage

• 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).
