Abstract: Use of heterogeneous nucleation allows the localized reduction of metal salt and also cross-link the carbon precursor in the same region. This cross-linked matrix act as the secondary heterogeneous sites for spontaneous Nano particle synthesis and growth during the process of pyrolysis. Selectively creating heterogeneous sites and reducing the metal precursor using highly focused energy beams create various metal-carbon composites with controlled metal positioning. This is such a unique process where a pretreatment process will control the fabrication of complex metal-carbon composite nano and microstructures. This greatly simplifies the fabrication process, facilitating nanostructures like Nano metal bulbs, nanometal pointed nanogaps and metal sandwich structures with such process. With several advantages ranging from electronics, catalysis, optics and several other bio-functionalization technologies, this enables materials with unique and hybrid advantages.

Abstract: This disclosure describes techniques for modifying application program interface (API) calls in a manner that can cause a device to render native three dimensional (3D) graphics content in stereoscopic 3D. The techniques of this disclosure can be implemented in a manner where API calls themselves are modified, but the API itself and the GPU hardware are not modified. The techniques of the present disclosure include using the same viewing frustum defined by the original content to generate a left-eye image and a right-eye image and shifting the viewport offset of the left-eye image and the right-eye image.

Abstract: A method is used in measuring data access activity. I/O data is analyzed that describes I/O activity for a slice of a logical volume. Based on the I/O data, a first value of data access activity is determined for the slice corresponding to a first time period, and a second value of data access activity is determined corresponding to a second time period. From the first and second values, an exponential moving average of data access activity is derived for the slice.

Abstract: Methods and systems are disclosed for relocating data in a physical storage pool comprising a plurality of storage tiers having differing performance characteristics, the physical storage pool being mapped into one or more logical units, each logical unit comprising a plurality of logical slices of data storage. The methods and systems can involve receiving a relocation list, the relocation list including, for each of a plurality of logical slices, a slice identifier, a temperature value, and a current physical location, determining a destination tier for each logical slice on the relocation list, evaluating for each logical slice on the relocation list a performance gain expected to be achieved by moving the logical slice from its current physical location to a new location in the destination tier, and relocating data in a logical slice from its current physical location to the new location based on the evaluation.

Abstract: A method is used in applying data access activity measurements. A slice relocation candidate list is generated which identifies slices to be relocated along with respective destination tier information. Slices in a pool are matched to respective matching tiers based on the slices' respective temperatures and tier preferences. Based on whether a current tier for a slice differs from the matching tier for the slice, the slice is listed in the relocation candidate list.

Abstract: Described are techniques for controlling performance of a data storage system. As a first part of an interactive dialogue, a policy is selected including one or more I/O classes each representing a logical grouping of I/O requests received at the data storage system. As a second part of the interactive dialogue, performance of said data storage system is monitored for each I/O class included in said policy without enforcing said policy. As a third part of the interactive dialogue, at least one performance goal associated with one of said I/O classes is set. The policy is run as a fourth part of the interactive dialogue causing enforcement of the policy on the data storage system in accordance with the at least one performance goal.

Abstract: A method for optimizing the operation of a data storage system utilizes a genetic algorithm to adjust internal parameters of the system. The method involves determining a set of optimum values of each of two or more different data array parameters, such as data request types that will be processed concurrently, to achieve performance goals that are set by the user for the system. The optimum values are determined by iteratively evaluating the performance of the system while it processes the different combinations of values of the two or more data requests, saving the combinations of numbers that yield performance parameters that approach the goal and eliminating combinations of number of data request types that do not.
