A computer system with a coupling facility is provided with a plurality of processors and a plurality of intersystem channels coupled to the processors via a memory bus. The coupling facility includes a memory bus interface for the memory bus and a plurality of channels for coupling said channels to said processors. The memory bus interface includes an adapter with at least two hardware vectors provided for command detection, command isolation, and parallel testing of the error states of the intersystem channels, one which detects a command vector arrival, and a second which contains error state vector indicators. A LOCATE CHANNEL BUFFER (LCB) instruction is employed which performs a sense and reset operation on the command vector to identify and isolate a new command, and subsequently reads a vector of said error states vector indicator to determine the presence or absence of link errors.

A system for cooling processor assembly is disclosed which comprises printed circuit boards (PCB) with a plurality of heat emitting electronic components, and a housing for each PCB with a heat sink covering at least partly the heat emitting electronic components. The housing comprises a base portion to which are transferred heat emitted by the electronic components. Furthermore, the system for cooling processor comprises a cooling plate on which are fixed in series the different PCBs by directly positioning the base portion of the housings onto the cooling plate. The housings for each PCB system include at their base portions clamps to be inserted into corresponding guiding holes of the cooling plate when a PCB together with its housing is positioned onto the cooling plate at a specific therefor dedicated place defined by the guiding holes. Advantageously, the PCB together with its housing is pressed against the cooling plate alongside the base portion when fixed onto the cooling plate allowing thermal coupling between the housing and the cooling plate and a hot plugging of the PCB onto the cooling plate without requiring interrupting the cooling process applied to the cooling plate.

The present invention relates to switching technology in computer networks and in particular to a method and system for switching information packets through a m input, n output device. According to the invention it is proposed to temporarily buffer said packets according to a new, self-explanatory, preferred a linear addressing scheme in which a respective buffer location of consecutive stream packets results from a respective self-explanatory, or linear, respectively, incrementation of a buffer pointer. Preferably, a matrix of FIFO storage elements (10,11,12,13) having an input and an output crossbar can be used for implementing input/output paralleling modes (ILP,OLP) and multiple lanes and achieving address input/output scaling up to a single cycle.

For record carriers with a greatly varying thickness of the metal layer, the burn out process is effected dynamically with respect to the current strength. During the starting phase up to the beginning of the actual arcing phase a relatively high current is applied which is sufficient to burn out even thick metal layers. As burning out proceeds, the print current, after a particular arc voltage has been reached, is reduced in a short time, maintaining the arc and avoiding an undesirable burning out which would increase the print spot. For thinner metal layers the burn out current is correspondingly lower. The maximum burn out current is automatically adjusted to the thickness of the metal layer by measuring the arc voltage between electrode and metal surface of the record carrier. Suitable arrangements for controlling the burn out current are characterized by an (arc) voltage-controlled current control circuit.
