....load among it s processors (e.g. in clusters with a distributed operating system like MOSIX [MCC00] The second layer is the Low Level Resource Management layer. It encompasses software packages that provide message passing mechanisms (e.g. MPI libraries) and scheduling systems (e.g. PBS [PBS99], LSF [LSF92] LoadLeveler [LL93] that are not a part of an operating system. This layer is especially important if the physical resource itself consists of several other individual resource units as it is the case when a cluster of networked machines is represented as a single resource.

....issued by the user. On many high performance resources such as large super computers or workstation clusters batch queuing systems or batch schedulers are in place to provide for the efficient use of the resource. Commonly deployed examples for such services are the Portable Batch Scheduler (PBS) [PBS99], LoadLeveler [LL92] and the Load Sharing Facility (LSF) LSF92] In a batch queuing system a user submits jobs to the batch scheduler, the batch scheduler adds the user s jobs to a queue (there might be multiple queues with different priorities) and issues job handles to the user. A user can use ....

High performance data transfers: Fast and simple access to images and user data is critical. Current grid solutions, such as Globus [4, 1] and PBS [3] typically employ file staging techniques to transfer files between user accounts in the absence of a common file system. File staging approaches require the user to specify the files to be transferred, transfer whole files when they are opened, and pose application programming challenges. Data ....

....clusters usable lies in the system software. In this paper, we presented our solution, STORM, which currently focuses on increasing the scalability and performance of job launching and process scheduling. 5. 1 Job launching Many run time environments, such as the Portable Batch System (PBS) [4], distribute executable files to all nodes via a globally mounted filesystem, typically NFS [35] The advantages of this approach are its simplicity and portability. However, because many clients are simultaneously accessing a single file on a single server, the shared filesystem approach is ....

This class of software environment is characterised by the user submitting inherently serial code with no intercommunication between di#erent pieces of code. Examples of this class are PBS [4], NQS [22] DQS [15] and LoadLeveler [10] These systems are compared and contrasted in detail in [3] Portable Batch System (PBS) was a project initiated by NASA to create an extensible batch processing system for heterogeneous networks. PBS allows users to initiate and execute the scheduling of ....

....[14] The system works by way of software proxies that broker transactions between standard NFS clients and servers; the proxies are dynamically configured and controlled by computational grid middleware. This mechanism differs from related work in filestaging techniques (e.g. Globus [4] and PBS [6, 3]) in that it supports user transparent, on demand transfer of data. It differs from related on demand data access solutions for grid computing (e.g. Condor [11] and Legion [5, 19] in that it does not require modifications to applications and it does not rely on non native file system servers. ....

....a user load that is more demanding than the load imposed by actual PUNCH users. 7. Related Work Current grid computing solutions typically employ file staging techniques to transfer files between user accounts in the absence of a common file system. Examples of these include Globus [4] and PBS [6, 3]. As indicated earlier, file staging approaches require the user to explicitly specify the files that need to be transferred, and are often not suitable for session based or database type applications. Some systems (e.g. Condor [11] utilize remote I O mechanisms to allow applications to access ....

Cluster management systems, e.g. Condor [17] and PBS [2], typically provide a command and or library interface to interact with the system. PUNCH accesses clusters resources via this interface [1] The interface varies from one cluster software to another, and can be divided into the following categories: 1) run specific information (e.g. tool input, ....
