Abstract

Monitoring of CPU consumption is a very basic requirement in many areas of software. It is especially valuable in the frame of Internet applications, in support of specific aspects such as security, reliability and adaptability. This paper is set in the context of J-RAF2, a Java-based framework exploiting bytecode rewriting techniques in order to garantee the portability of CPU-managed applications. We briefly recall this implementation technique and present an example of CPU monitoring module to validate this new approach. Depending on the application, resource management may involve simple low-level accounting of CPU usage, or higher-level tools that collect accounting information from several sources in order to enforce sophisticated strategies. This paper shows that CPU monitoring modules may be easily built to work on top of classes rewritten with J-RAF2, and that they will be entirely portable across many kinds of Java deployment technologies (standalone applications, applets, servlets).

Central processing unit

A central processing unit (CPU)—also called a central processor or main processor—is the most important processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged.

CPU cache

A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1.

High-level synthesis

High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior. Synthesis begins with a high-level specification of the problem, where behavior is generally decoupled from low-level circuit mechanics such as clock-level timing.
