Thursday, September 17, 2009. Installation Process of Linux. Linux Installation, Step by Step. If you have come directly to this page hoping to install Linux without doing any more reading, I suggest that you reconsider. Without the proper knowledge and preparation, attempting to install any operating system (whether Linux or any other) can be a disaster. So before I launch into the resources for your step by step Linux installation, here are some things you should already have read:. This book contains ...

Thursday, August 20, 2009. Recovery or Deadlock Recovery. Abort all deadlock processes. And release resource - too drastic. Will lead to loss of work. Abort one process at a time. Releasing resources until no deadlock. How do we determine which process to abort first? Process which has done least work. Processes from a previous checkpoint. Ie before it claimed any resources. Difficult to achieve - sometimes impossible. Complex decisions due to the large number of processes present within a system. Resour...

Thursday, August 20, 2009. No Preemption –. If a process that is holding some resources requests another resource that cannot be immediately allocated to it, then all resources currently being held are released. Preempted resources are added to the list of resources for which the process is waiting. Process will be restarted only when it can regain its old resources, as well as the new ones that it is requesting. Deadlock prevention - low device utilization and reduced system throughput. Unsafe State in ...

If graph contains no cycles. If graph contains a cycle. If only one instance per resource type, then deadlock (meaning if the cycle goes on a single path, it will result to a DEALOCK).

Thursday, August 20, 2009. In Operating Systems a special resource-allocation graph algorithm can be used to detect whether there is any deadlock in the system. A resource-allocation graph is a directed graph consisting of two different types of nodes P. The set consisting of all active processes in the system, and R. The set consisting of all resource types in the system. A directed edge from process P. Is denoted by P. And means that process P. Requested an instance resource type R. Is denoted by R.
