Various embodiments of the present invention provide a method, system, and program product that perform the following operations: organizing a project having source code into a stacked-layer framework, the stacked-layer framework having: (i) a code layer including the source code of the project, (ii) a label layer including one or more label pages labelling the source code according to respective features of the source code, and (iii) a mask layer including one or more mask pages concealing portions of the source code according to labels of the label layer; receiving a request from a user to utilize a portion of the project, wherein the request includes a user requirement identifying one or more desired features; identifying a mask page of the one or more mask pages corresponding to the one or more desired features identified by the user requirement; and communicating the identified mask page to the user.

Delivering portions of source code based on a stacked-layer framework

Methods, systems, and computer program products for container image management are disclosed. In a method, a first group of operations that are performed in respective layers in a base image are obtained. A second group of operations that are performed in respective layers not comprised in the base image are obtained. The second group of operations are optimized based on a comparison between the first and second groups of operations. A destination container image is generated based on the optimized second group of operations and the base image.

Container image management

Intelligent layer control for building image files into new container images while avoiding redundant files stored between read-write and read-only image layers. Pre-commit processing module (PPM) filters updated files. Hash values of updated files are compared with hash values of original files. Where hash values are the same, PPM generates an OMD file that updates the inode metadata of original files with metadata of the updated file and removes the updated file. Hash values that are not the same, with differ values less than a threshold value, PPM generates an OMD file with updates to the inode metadata, content change flag and/or delta content info reflecting the updated file and removes updated file from container file system. OMD files are passed to storage driver whereby metadata and/or changes to content are overridden and merged with original file content generating a single unified user view of the container file system.

Intelligent layer control of redundant content in container images

Embodiments provide enhanced performance diagnosis in a network computing environment. In response to an occurrence of a performance issue for a node while under operating conditions, common logs for applications on the node are analyzed. The applications are respectively registered in advance for diagnosis services. The applications each register rules in advance for the diagnosis services. At a time of the performance issue, debug programs are automatically issued to generate debug level logs respectively for the applications. Debug level logs are analyzed according to the rules to determine a root cause of the performance issue. A potential solution to the root cause of the performance issue is determined using the rules, without having to recreate the operating conditions occurring during the performance issue. The potential solution to rectify the root cause of the performance issue is executed without having to recreate the operating conditions occurring during the performance issue.

Methods, computer program products, and/or systems are provided that can perform the following operations: receiving a connection request from a first user device; creating an authentication container for the first user device; authenticating the first user device using the authentication container; in response to authentication for the first user device being successful, creating a first user request processing container for the first user device; and processing user requests received from the first user device using the first user request processing container.

Providing isolated containers for user request processing

A method of translating a first command to a target command includes receiving the first command in a first command format, acquiring a first utility intermediate representation framework (UIRF) including a plurality of a first set of node instances. The method also includes acquiring a first user utility intermediate representation framework (UUIRF) by parsing the first command into one or more command elements, representing each command element by a respective node instance of the first UIRF, the first UUIRF representing an intention of the first command, acquiring a target UUIRF based on a target format, the target UUIRF including a target set of node instances, entering information from each of the first set of node instances of the first UUIRF into a corresponding node instance of the target set of node instances in the target UUIRF, and constructing the target command based on the target UUIRF.

The present invention discloses a radiation-hardened-by-design (RHBD) multi-gate device and a fabrication method thereof. The multi-gate device of the present invention includes a substrate; a source region and a drain region, which are on the substrate; a protruding fin structure and a field dielectric layer between the source region and the drain region on the substrate; a gate dielectric and a gate electrode on the fin structure and the dielectric layer; and two isolation layers separated to each other, which are disposed in the drain region between the adjacent two fins, wherein an interlayer is sandwiched between the two isolation layers. The interlayer has a doping type which is opposite to that of the substrate so that a shunt PN junction is formed between the interlayer and the substrate, and the shunt PN junction has an electrode not connected to the drain so that a part of the charges collected by the shunt PN junction are not output to the drain and are ultimately guided out of the multi-gate devices, thereby weakening the influence of the single-event effect. In comparison with a multi-gate device of prior art, the multi-gate device of the present invention may effectively suppress the sensitivity of the device to single event irradiation in the event that the layout areas of the two types of devices are almost same.

Radiation-hardened-by-design (RHBD) multi-gate device

A CMOS device for reducing a radiation-induced charge collection and a method for fabricating the same. In the CMOS device, a heavily doped charge collection-suppressed region is disposed directly under the source region and the drain region. The region has a doping type opposite that of the source region and the drain region, and has a doping concentration not less than that of the source region and the drain region. The charge collection-suppressed region has a lateral part slightly less than or equal to that of the source region and the drain region, and has a lateral range toward to the channel not exceed the edges of the source region and the drain region. The CMOS device may greatly reduce a range of the funnel that appears under the action of a single particle, so that charges collected instantaneously under a force of an electric field may be reduced.

The present invention discloses a CMOS device of reducing charge sharing effect and a fabrication method thereof. The present invention has an additional isolation for trapping carriers disposed right below an isolation region. the material of the additional isolation region is porous silicon. Since porous silicon is a functional material of spongy structure by electrochemistry anodic oxidizing monocrystalline silicon wafer, there are a large number of microvoids and dangling bonds on the surface layer of the porous silicon. These defects may form defect states in a center of forbidden band of the porous silicon, the defect states may trap carriers so as to cause an increased resistance. And with an increase of density of corrosion current, porosity increases, and defects in the porous silicon increase. The present invention can reduce the charge sharing effect due to heavy ions by using a feature that the defect states in the porous silicon trap carriers, the formation of a shallow trench isolation (STI) region and a isolation region underneath only needs one time photolithography, and the process is simple, so that radioresistance performance of an integrated circuit may be greatly increased.
