Information is more efficiently distributed between master and slave information handling systems interfaced through a blocking network of switches by storing the information on switches within the blocking network and distributing the information from the switches. As an example, an application distribution module located on a leaf switch distributes an application, such as an operating system, to connected slave nodes so that the slave nodes do not have to retrieve the operating system from the master node through the blocking network. For instance, a PXE boot request from a slave node to the master node is intercepted at the leaf switch to allow the slave node to boot from an image of the operating system stored in local memory of the leaf switch.

An exemplary fast start-up crystal oscillator with reduced start-up time. The exemplary oscillator reduces the start-up time (i.e., the time taken to attain sustained stable oscillations after the power is turned on) by increasing the negative resistance of a circuit. Increasing the negative resistance increases the rate of growth of the oscillations, thereby reducing start-up time. The exemplary crystal oscillator includes a gain stage with negative resistance. A crystal with shunt capacitance is placed in the feedback loop of the gain stage. A buffer is coupled to the gain stage such that it blocks the crystal shunt capacitance from loading the gain stage, effectively increasing the negative resistance of the gain stage. Further, an oscillation detection and control circuit is coupled between the crystal and the gain stage. The oscillation detection and control circuit connects the buffer during start-up, and disconnects the buffer once an oscillation signal attains sustained stable oscillations.
