I have my two initial benchmark applications coded up. They still need some testing, and I still need to finalize the workload generation, but having the apps down on the machine is nice.

I haven't touched the multi-machine code in a week. It just got to me after a while. The serialization aspect was killing me. I've decided to use the boost serialization library. At first I didn't think there was that much that I needed serialization for, but I eventually figured out that was not definitely not the case. Using the boost library will allow me to keep drastic changes between the trunk development of Lagniappe and the multi-machine branch, which will hopefully mean that the multi-machine support will be easier to merge back in when it's all said and done.

While the OSDI deadline has come and gone, I am now making the final push towards defending and turning in my dissertation by the middle of August. Needless to say, this is the most important deadline I've ever run up against and it's not okay to pull the paper for this one.

I am working on two major tasks regarding the main system. The first is making Lagniappe function on multiple machines at the same time. If Lagniappe runs on multiple machines, the true heterogeneity of multi-* becomes an issue (as now we have a drastically different communication channel in the mix). The second task is combining operators based on their state preferences. I feel that we can truly answer the pipelined vs. parallel question based on the state access semantics of the operators in an application.

The third major issue is creating a suite of benchmark applications. The benchmarks has been a thorn in my side for a while, but I am confident we can make it all come together.
