A method for installing tiles includes the steps of positioning a base in overlying relation to cementitious material. First and second spacer arms are formed on the base in normal relation to one another. Preselected corners of four tiles are positioned in overlying relation to the base and are spaced apart from one another by the spacer arms. A post having ratchet teeth is formed integrally with the base at the center of the base. A disc receives the post and a pawl formed in the disc prevents displacement of the disc away from the base. The disc is positioned in overlying relation to the four corners of the tiles so that it overlies and holds the tiles level between the base and the disc. After curing of the cementitious material, an installer twists the disc in a plane parallel to the tiles until the post breaks off.

A smooth layer of a metal is electroplated onto a microrough electrically conducting substrate by immersing the substrate and a counterelectrode in an electroplating bath of the metal to be electroplated and passing a modulated reversing electric current between the electrodes. The current contains pulses that are cathodic with respect to said substrate and pulses that are anodic with respect to said substrate. The cathodic pulses have a duty cycle less than about 50% and said anodic pulses have a duty cycle greater than about 50%, the charge transfer ratio of the cathodic pulses to the anodic pulses is greater than one, and the frequency of said pulses ranges from about 10 Hertz to about 12000 Hertz. The plating bath is substantially devoid of levelers and may be devoid of brighteners.

One embodiment of the present invention sets forth a technique for scheduling thread execution in a multi-threaded processing environment. A two-level scheduler maintains a small set of active threads called strands to hide function unit pipeline latency and local memory access latency. The strands are a sub-set of a larger set of pending threads that is also maintained by the two-leveler scheduler. Pending threads are promoted to strands and strands are demoted to pending threads based on latency characteristics. The two-level scheduler selects strands for execution based on strand state. The longer latency of the pending threads is hidden by selecting strands for execution. When the latency for a pending thread is expired, the pending thread may be promoted to a strand and begin (or resume) execution. When a strand encounters a latency event, the strand may be demoted to a pending thread while the latency is incurred.
