Towards Deployment-Time Dynamic Analysis of Server Applications. In Proceedings of the 13th International Workshop on Dynamic Analysis (WODA). Bug-finding tools based on dynamic analysis (DA), such as Valgrind or the compiler sanitizers provided by Clang and GCC, have become ubiquitous during software development. These analyses are precise but incur a large performance overhead (often several times slower than native execution), which makes them prohibitively expensive to use in production. In t...

Varan - Multi-version execution. With the widespread availability of multi-core processors, running multiple diversified variants or several different versions of an application in parallel is becoming a viable approach for increasing the reliability and security of software systems. The key component of such N-version execution (NVX) systems is a runtime monitor that enables the execution of multiple versions in parallel. SRG homepage for Varan. October, 2015. Extended abstract.

Usages of sun.misc.Unsafe within Rubah. Is a Dynamic Software Updating system for Java that works on the stock Oracle HotSpot JVM, does not add any measurable overhead when running a program, and performs dynamic software updates efficiently. In this post, I explain how Rubah uses the low-level unsafe operations available in class. What is sun.misc.Unsafe? For instance, the following code sets an entire integer array to 1 using the unsafe API to avoid any bounds check:. Most of the low-level memory opera...

John Regehr, Professor of Computer Science, University of Utah, USA. The Strict Aliasing Situation is Pretty Bad. I’ll start with a quick review of the strict aliasing rules in C and C and then present some less well-known material. Compiler optimizations are often shot down by the potential for pointers to be aliases. For example, although we might naively expect a compiler to optimize this function to return zero, that cannot happen because x and y might refer to the same location:. Gcc-5 strict.c ...

Luis H. Pine, Composer
Whether it is in a dreamer’s head. Preparations are in progress for the recording of Presidential Debates and Speeches, a two-movement piece for Wind quintet. Gabriel, a piece for organ and solo trumpets, was recorded in San Francisco's Saint Mary's Cathedral. Musicians John Freeman and Paul Rosas, together with engineer/musician Nahuel Bronzini, made it a perfect session. Seraphim, a piece for string quartet, is in its final stages of composition. A CD/DVD project is in planning for release in 2015/2016.
