Service-oriented systems' distributed ownership has led to an increasing focus on runtime management solutions. Service-oriented systems can change greatly after deployment, hampering their quality and reliability. Their service bindings can change, and providers can modify the internals of their services. Monitoring is critical for these systems to keep track of behavior and discover whether anomalies have occurred. The Service-Centric Monitoring Language (SECMOL), a general monitoring specification language, clearly separates concerns between data collection, data computation, and data analysis, allowing for high flexibility and scalability. SECMOL also presents a concrete projection of the model onto three monitoring frameworks.

Graphics Processing Units accelerate data-parallel graphic calculations using wide SIMD vector units. Compiling programs to use the GPU's SIMD architectures require converting multiple control flow paths into a single stream of instructions. IF-conversion is a compiler transformation, which converts control dependencies into data dependencies, and it is used by vectorizing compilers to eliminate control flow and enable efficient code generation. In this work we enhance the IF-conversion transformation by using a block unification method to improve the currently used block flattening method. Our experimental results demonstrate that our IF-conversion method is effective in reducing the number of predicated instructions and in boosting kernel execution speed.
