Abstract: A method is described for scheduling in an intelligent manner a plurality of threads on a processor having a plurality of cores and a shared last level cache (LLC). In the method, a first and second scenario having a corresponding first and second combination of threads are identified. The cache occupancies of each of the threads for each of the scenarios are predicted. The predicted cache occupancies being a representation of an amount of the LLC that each of the threads would occupy when running with the other threads on the processor according to the particular scenario. One of the scenarios is identified that results in the least objectionable impacts on all threads, the least objectionable impacts taking into account the impact resulting from the predicted cache occupancies. Finally, a scheduling decision is made according to the one of the scenarios that results in the least objectionable impacts.

Abstract: Methods for preparing for analysis of surface contamination of magnetic tape, in one embodiment, submerses and passes a continuing length of the magnetic tape through a covered water bath; and subsequent to the submersing step, wipes the continuing length of the magnetic tape while covered. The preparation is conducted, in one embodiment, with a covered enclosure configured to enclose a water bath to a level at least submersing guide(s) and a continuing length of the magnetic tape passed by the guide(s). A wiping arrangement is configured to wipe the continuing length of magnetic tape subsequent to the submersion in the water bath. Further, the covered enclosure comprises openings therein to pass the continuing length of magnetic tape.

Abstract: Methods and apparatus provide for non-destructive cleaning of magnetic tape. In one embodiment, a continuing length of the magnetic tape is submersed and passed through a covered solvent bath; and each side (front and back) of the continuing length of magnetic tape is swabbed with a cotton swab subsequent to the submerging step. The cotton swabs are arranged to swab each respective side of the magnetic tape.

Abstract: A thread (or other resource consumer) is compensated for contention for system resources in a computer system having at least one processor core, a last level cache (LLC), and a main memory. In one embodiment, at each descheduling event of the thread following an execution interval, an effective CPU time is determined. The execution interval is a period of time during which the thread is being executed on the central processing unit (CPU) between scheduling events. The effective CPU time is a portion of the execution interval that excludes delays caused by contention for microarchitectural resources, such as time spent repopulating lines from the LLC that were evicted by other threads. The thread may be compensated for microarchitectural contention by increasing its scheduling priority based on the effective CPU time.

A second burner (80) communicates with the second portion of the housing for preheating the first portion. The testing method of an associated construction material sample includes installing the sample in the housing, preheating the housing, introducing a flame toward the sample, monitoring the flame as combustion progresses longitudinally along the sample, and recording data regarding the flame progression.

Abstract: Methods, computer programs, and systems for managing thread performance in a computing environment based on cache occupancy are provided. In one embodiment, a computer implemented method assigns a thread performance counter to threads being created to measure the number of cache misses for the threads. The thread performance counter is deduced in one embodiment based on performance counters associated with each core in a processor. The method further calculates a self-thread value as the change in the thread performance counter of a given thread during a predetermined period, and an other-thread value as the sum of all the changes in the thread performance counters for all threads except for the given thread. Further, the method estimates a cache occupancy for the given thread based on a previous occupancy for the given thread, and the calculated shelf-thread and other-thread values. The estimated cache occupancy is used to assign computing environment resources to the given thread.

Abstract: A one-component, moisture-curing silicone rubber roof coating or sealant is manufactured using approximately 5-30% recycled EPDM rubber fill. The coating can be incorporated with a polyurethane foam insulation layer to form a roof assembly. Preferably, the EPDM roofing material is removed from an existing structure. It is processed forming powder on the order 50-200 mesh particle size and incorporated into a solvent-free silicone polymer to form a coating or sealant.
