Request dispatching mechanism is at the heart of any cluster-computing environment. The goal is to support a single service provider address image for a given cluster of workstations. That is to say a given cluster publicise a single IP address and client requests are addressed to that IP address. This means, from the client's viewpoint, there are no nodes in the cluster, only services non the network names through which they are accessible. As a result, the cluster becomes a single virtual none. In this paper we propose a simple and elegant scheme for making the cluster transparent to clients outside the cluster such that the clients can interact with the cluster as if it were a single high-performance anti highly available resource.

An automatic system for measuring micro flow rate of liquid is presented. A computer mouse device was modified as an optical encoder for this purpose. All the sensing and electrical signal are processed by the mouse device. A very simple structure has been realized using the PS/2 mouse interface to get electric power and transfer the data to computer directly. The data treatment was programmed using Microsoft Visual Basic. This system shows a useful solution for micropump evaluation. Because this device works in digital On/Off principle, there is no lower limit for measurable range of flow rate and bidirectional measurement is also possible. The full measurable range is up to 115 /spl mu/l/min, at which the measurement precision is assured within /spl plusmn/2%. The resolution is dependent on the sampling speed of the computer (0.05 second). The device is not affected by the change of temperature or thermal capacity of fluids. It is an alternate as a tool to calibrate mass flow meter. Automatic parallel measurements in multi-channel are also possible.

Human aortic endothelial cells (HAEC) were cultured on a pre-stretched elastic substrate which, when released, shortened the attached cells to characterize resting tension in the actin cytoskeleton (CSK). The presence of buckled and unbuckled parallel actin stress fibers suggests CSK prestretch may be non-uniformly distributed.
