This paper describes a concurrent programming environment for the Intel's 486 processor family. The environment uses the processor's advanced features, like memory management, multitasking and protection, to supply the application level with a compact and secure execution environment. Regarding process management, the environment supports multitasking,(More)
As IC technology scales down, interconnect issues are becoming one of the major concerns of gigahertz System-on-Chip (SoC) design. Voltage distortion (power supply noise) and delay violations (signal and clock skews) dramatically contribute to signal integrity loss. As a consequence, performance degradation, reliability problems and ultimately, functional(More)
Large computing clusters used for scientific processing suffer from systemic failures when operated over long continuous periods for executing workflows. Diagnosing job problems and faults leading to eventual failures in this complex environment is difficult, specifically when the success of whole workflow might be affected by a single job failure. In this(More)
We present a configurable standard environment for electromagnetic (EM) immunity measurement of prototype system-on-chip (SoC). The environment is composed of two boards compliant with the 62.132-2 and 62.132-4 IEC Std Parts, being conceived for radiated and conducted measurements, respectively. The SoC under test can be prototyped on two types of ICs: two(More)
The CDF and D0 experiments probe the high-energy frontier and as they do so have accumulated hundreds of Terabytes of data on the way to petabytes of data over the next two years. The experiments have made a commitment to use the developing Grid based on the SAM system to handle these data. The D0 SAM has been extended for use in CDF as common patterns of(More)
