Methods and systems for in-memory metadata reduction in cloud storage system are provided. According to an aspect, a method comprises receiving a first command to write a data stream to a storage device; writing the data stream into a plurality of fragments having logical addresses corresponding to physical addresses on the storage device; and generating an index for individual fragment of the plurality of fragments, the index indicating information to locate the physical addresses of the individual fragment. Individual records in the individual fragment have a same pre-set logical size and all individual records in the individual fragment are continuous, and the index indicates the information including at least: an offset value of the individual record in the individual fragment; the pre-set logical size of the individual record; and a pre-set physical size of the individual record.
A storage record engine implemented on a storage system is provided. The storage record engine further organizes hosted storage of the storage system into superblocks and chunks organized by respective metadata, the chunks being further organized into chunk segments amongst superblocks. Persistent storage operations may cause modifications to the metadata, which may be recorded in a transaction log, records of which may be replayed to commit the modifications to hosted storage. The replay functionality may establish recovery of data following a system failure, wherein replay of records of transaction logs in a fashion interleaved with checkpoint metadata avoids preemption of normal storage device activity during a recovery process, and improves responsiveness of the storage system from the perspective of end devices.
The present disclosure provides a computer-implemented method for encoding video. The method includes: determining whether a coded video sequence (CVS) contains equal number of profile, tier and level (PTL) syntax structures and output layer sets (OLSs); and in response to the CVS containing equal number of PTL syntax structures and OLSs, coding the bitstream without signaling a first PTL syntax element specifying an index, to a list of PTL syntax structures in the VPS, of a PTL syntax structure that applies to a corresponding OLS in the VPS.

Method and system for training machine learning system
The present disclosure provides a method and a system for training a machine learning system. Multiple pieces of sample data are used for training the machine learning system. The method includes acquiring multiple sample sets, each sample set including sample data in a corresponding sampling time period; setting a sampling rate for each sample set according to the corresponding sampling time period; acquiring multiple sample sets sampled according to set sampling rates; determining importance values of the multiple sampled sample sets; correcting each piece of sample data in the multiple sampled sample sets by using a corresponding importance value to obtain corrected sample data; and inputting the corrected sample data into the machine learning system to train the machine learning system.
A system includes a central processing unit (CPU) and a programmable device. The programmable device is communicatively coupled to the CPU. The programmable device is configured to provide a message header of an acquired to-be-processed message to the CPU. The CPU is configured to: process the message header to obtain a target message header; and provide the target message header to the programmable device. The programmable device is further configured to splice the target message header with a payload portion of the to-be-processed message to obtain a target message; and forward the target message to a target node referred to in the target message header.
Aspects of the present technology are directed toward three-dimensional (3D) stacked processing systems characterized by high memory capacity, high memory bandwidth, low power consumption and small form factor. The 3D stacked processing systems include a plurality of processor chiplets and input/output circuits directly coupled to each of the plurality of processor chiplets.
