In total, iGUARD detected 57 races in 21 GPU programs, without false positives. It detected previously unknown subtle bugs in popular GPU programs, including three in NVIDIA supported commercial libraries. Importantly, iGUARD detects newer types of races that were hitherto not possible for any known tool. The GPU's parallelism helps speed up race detection by 15x over a closely related prior work. We thus perform the race detection on the GPU itself without relying on the CPU. A key need for a race detector to be practical is to accurately detect races at reasonable overheads. We present iGUARD, a runtime software tool to detect races in GPU programs due to incorrect use of such advanced features. While these features can speed up many applications and enable newer use cases, they can also introduce subtle synchronization errors if used incorrectly. To cater to the needs of emerging applications with semantically richer and finer grain sharing patterns, GPU vendors have been introducing advanced programming features, e.g., scoped synchronization and independent thread scheduling. ISS iGuard is a total personal solution for you.Ĭontinued use of GPS running in the background can dramatically decrease battery life.Newer use cases of GPU (Graphics Processing Unit) computing, e.g., graph analytics, look less like traditional bulk-synchronous GPU programs. Businesses can monitor the safety of their employees directly to existing computer systems with internet access. Users can login to the ISS iGuard portal via the website to manage their account, update their profile and view alerts. ISS iGuard cab also look after your business requirements monitoring and protecting your employee offering a complete business solution and compiles with BS8484 OH&S standards. If you have made a mistake you can cancel your emergency by keying in your PIN and your contacts will be updated. Video and Audio of your situation is sent to the ISS iGuard cloud and on to your contacts. You emergency contacts will be sent an SMS of your present location and your emergency escalation requirements will be activated. If you are concerned for your safety then simply shake the phone and ISS iGuard will do the rest. When you need the protection of ISS iGuard you login to the App and you are then being monitored. Simply download the App onto your smart phone, follow the prompts and you are ready to go. ![]() Whether you are a shift worker, out on the town, working in a dangerous location or area, or want to know that your family is safe, then ISS iGuard is for you. ISS iGuard is a revolution in 24 hour personal security protection.
