Publication number: 20180203611Abstract: A method for optimizing data storage for write-in-free-space workloads is disclosed. In one embodiment, such a method includes receiving a write request to write an updated version of data to a new block address in free space. The new block address maps to a destination extent. The method further determines an old block address, mapping to a source extent, storing a previous version of the data. The method determines whether the source extent is the same as the destination extent. If the source extent is not the same as the destination extent (i.e., the old block address and new block address point to blocks in different extents), the method transfers temperature statistics associated with the old block address from the source extent to the destination extent. The method writes the updated version of the data to the new block address. A corresponding system and computer program product are also disclosed.Type: ApplicationFiled: January 19, 2017Publication date: July 19, 2018Applicant: International Business Machines CorporationInventor: Xue Qiang Zhou

Publication number: 20180183461Abstract: An electronic device has a transmit circuit and a processing circuit. The processing circuit outputs a first portion of compressive sensing (CS) samples corresponding to a signal segment to another electronic device via the transmit circuit, and selectively outputs a second portion of the CS samples corresponding to the signal segment to another electronic device via the transmit circuit according to a response of another electronic device. In this way, a balance between the compression ratio and the reconstruction quality/speed can be achieved. Moreover, the signal reconstruction performed at the processing circuit may employ a multi-resolution/multi-scale reconstruction scheme to achieve a balance between the dictionary size and the reconstruction quality/speed, and/or may employ a multi-stage reconstruction scheme to achieve a balance between the reconstruction algorithm control setting and the reconstruction quality/speed.Type: ApplicationFiled: December 4, 2017Publication date: June 28, 2018Inventors: Qiang Zhou, Hua Wang, Yun-Shiang Shu, Bao-Chi Peng
