Drug solutions are prepared by removing drug from one or more masses of a solid form of the drug. These mechanisms and methods for applying a public tag to information may enable embodiments to allow a user to apply a public tag to the information once. Such a method includes generating a dependent texture read request at logic configured to perform shader computations corresponding to a first thread, and sending shader-calculated, texture-sampling related parameters corresponding to the first thread to a texture pipeline while retaining at the logic all other shader processing related information corresponding to the first thread.
