AFS is a worldwide distributed file system that supports several advantages over NFS, like better administration and availability. Arla is a free AFS-client, today available for a number of systems for which there are not any Transarc clients. Porting it to new systems is not hard. Arla also has some disconnected functionality and supports encryp-tion of(More)
As a practical means of achieving better security and single sign-on, the Kerberos network authentication system has been in wide use in the Unix world for many years. Microsoft has included its own implementation in Windows 2000, replacing the NTLM authentication system from older Windows NT versions. This facilitates sharing account information between(More)
We present PerfMiner, a system for the transparent collection , storage and presentation of thread-level hardware performance data across an entire cluster. Every sub-process/thread spawned by the user through the batch system is measured with near zero overhead and no di-lation of run-time. Performance metrics are collected at the thread level using tool(More)
This master thesis will investigate one solution to the problem issues with nested stochastic simulation arising when the future value of a portfolio need to be calculated. The solution investigated is the Least-squares Monte-Carlo method, where regression is used to obtain a proxy function for the given portfolio value. We will further investigate how to(More)
