摘要： A computer implemented method is disclosed for obtaining file-level information from block level information of files stored on a storage medium. The method includes accessing the storage medium to obtain metadata available in block level on the storage medium and building an inverse block-to-file map of the files stored on the storage medium. The method also includes listening online to incoming block-level commands communicated from a host to the storage medium, parsing the incoming block-level commands, inferring file-level information from the parsed block level commands; and updating the inverse file-level map. Also disclosed are corresponding computer program product and processing system.

摘要： Methods and systems for improving performance in a virtualization environment. The method comprising: detecting, by a first software, a first set of features supported by a hardware device, wherein the first software runs on the hardware device; detecting a second set of features with which to run a second software, wherein the second software is launched by the first software with the second set of features; exposing one or more features in the second set of features to the second software, wherein the second software detects and enables the exposed features for a third software launched by the second software; and emulating a first feature without causing a trap such that control is transferred to the second software, in response to determining that the first feature is an exposed feature not included in the first set of features, wherein one or more sensitive events are associated with the first feature.

摘要： A data transmission optimization method and system. The method comprises analyzing program code to identify data access calls in the program code, using one or more processor; determining whether a first data access call is for retrieving target data stored in a data structure with a plurality of fields, wherein the target data is stored in one or more target fields of the data structure; determining whether servicing the first data access call will result in transfer of non-target data stored in one or more non-target fields in the data structure; and replacing the first data access call with a second data access call, wherein servicing the second data access call will result in transfer of the target data and minimizes the transfer of non-target data.

摘要翻译： 数据传输优化方法和系统。 该方法包括使用一个或多个处理器来分析程序代码以识别程序代码中的数据访问调用; 确定第一数据访问呼叫是否用于检索存储在具有多个字段的数据结构中的目标数据，其中所述目标数据被存储在所述数据结构的一个或多个目标字段中; 确定是否服务于第一数据访问呼叫将导致存储在数据结构中的一个或多个非目标字段中的非目标数据的传送; 并且用第二数据访问呼叫替换第一数据访问呼叫，其中服务于第二数据访问呼叫将导致目标数据的传送并使非目标数据的传送最小化。
