Reset mguard smart6/26/2023 ![]() Anything more complex would have such a big architectural impact that it would not be justifiable against the fact, that all this effort is relevant just for 32-bit address space. If the usage from GUI thread would be still desirable, the fetch/offload could regularly call QCoreApplication::processEvents() to keep GUI at least partially responsive. Also such data would be mostly required in background thread where the overhead of fetch/offload would not block the GUI. ![]() multi_img instances) but not for data that are used for rendering (e.g. In case it would be implemented, it should be used only for data structures that are used infrequently (e.g. Still, I consider it interesting to mention how the desperate situation on 32-bit could be improved. Template class SharedData īecause Gerbil is primarily targeted for 64-bit, the whole offloadable concept is of low priority or could be skipped entirely in the final implementation. Another possibility is to use mutexes from TBB, which somewhat similar to boost mutexes. Regarding the technology used for locks, I would prefer boost rather than Qt as the synchronization support is more carefully designed. A DMZ scenario can be established either between two mGuard s (see Figure 1-3) or via a dedicated DMZ port of the TC MGUARD RS4000 3G, TC MGUARD RS4000 4G or FL MGUARD RS4004. intersection with old ROI), unlock, calculate the rest of new data, write-lock the original data structure, swap the internal plain pointer, unlock and deallocate the original data. Background thread would allocate new data structure, read-lock the original data structure, copy any usable data (e.g. Navigate to your region at the bottom of this page and select the country in which your company is located. The readers would read-lock and unlock those structures regularly when refreshing GUI. mGuard Secure Cloud // Instant Remote Services For A Smart Industry PHOENIX CONTACT Cyber Security. To support this, data structures have to be encapsulated into wrapper class providing read-write lock allowing multiple readers but only a single writer in the critical section. ![]() The GUI thread should just read those data for drawing purposes. Most of the big data structures that are currently owned by one of the widgets need to be modified in background in order to keep GUI responsive. The purpose of this document is to establish common ground for discussion and gradual refinement of the design. There might be errors or defficiencies in the design integrity and pseudocode, which will be gradually resolved during implementation. Disclaimer: Design concepts in this document shall be understood as a first sketch, they are by no means final.
