This is the final technical/scientific report for a heavy ion research program on the PHOBOS experiment at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory.

Simple Linux Utility for Resource Management (SLURM) is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for Linux clusters of thousands of nodes. Components include machine status, partition management, job management, scheduling and stream copy modules. The design also includes a scalable, general-purpose communication infrastructure. This paper presents a overview of the SLURM architecture and functionality.

SensIDA and IDA are general-purpose codes for solving differential-algebraic equation (DAE) initial value problems. SensIDA is a variant of IDA that includes options for simultaneously computing the DAE solution together with its first-=order sensitivity coefficients with respect to model parameters. SensIDA is written in ANSI-standard C and it is mainly based on IDA, DASPK3.0, and SensPVODE. IDA is based on DASPK2.0. DASPK3.0 is a Fortran77 code for the sensitivity analysis of DAE initial value problems. SensPVODE is a sensitivity analysis variant of the parallel ordinary differential equation solver PVODE. SensIDA can be compiled to run on serial or parallel computers. This is accomplished by specifying that the serial or parallel version of the vector module NVECTOR is used when compiling SensIDA. The parallel version of SensIDA uses MPI (Message-Passing Interface) to achieve parallelism, and is intended for a distributed Single Program Multiple Data environment in which all vectors are identically partitioned across processors. The idea is for each processor to solve a certain fixed subset of the DAEs that describe the model problem and the first-order sensitivity coefficients of the solution.

This project developed a comprehensive mathematical and simulation model for calculating thermal hydraulic, electrochemical, and corrosion parameters, viz. temperature, fluid flow velocity, pH, corrosion potential, hydrogen injection, oxygen contamination, stress corrosion cracking, crack growth rate, and other important quantities in the coolant circuits of water-cooled nuclear power plants, including both Boiling Water Reactors (BWRs) and Pressurized Water Reactors (PWRs). The model is being used to assess the three major operational problems in Pressurized Water Reactors (PWR), which include mass transport, activity transport, and the axial offset anomaly, and provide a powerful tool for predicting the accumulation of SCC damage in BWR primary coolant circuits as a function of operating history. Another achievement of the project is the development of a simulation tool to serve both as a training tool for plant operators and as an engineering test-bed to evaluate new equipment and operating strategies (normal operation, cold shut down and others). The development and implementation of the model allows us to estimate the activity transport or "radiation fields" around the primary loop and the vessel, as a function of the operating parameters and the water chemistry.
