![]() ![]() Run Check Disk or disk verification on the volumes associated with this client computer. Also try turn off any firewall program which can cause the backup to hang. Also, verify there is not an energy saver that turns off the client computer during the backup. Make sure to bind retrospect client to the right network card (if you have two network cards).Įnsure there are no unnecessary activities such as disk optimization, virus scans, screen savers, or memory-intensive or processing-intensive applications running on the client during the backup. Verify TCP/IP settings are correct and proper for the client computer. A crossover ethernet cable between the backup computer and a problem client allows you to do this. Try to back up through a direct connection between the host and client computer. Try a backup from this new computer to see if the original backup computer was causing the problem. Install a copy of the Retrospect application on a different computer. Try new hub, switch, connectors, and a network cable.ĭisconnect all external peripherals from the client computer and try backing up the internal hard drive. How does one client speed compare with clients that are backing up successfully? ![]() Try switching a wireless client to a wired connection to see if it helps.Ĭheck the Client connection speed Sources>Refresh (Macintosh). A 5GHz connection can sometimes have a shorter network range and could cause more network connection to drop if the client is a longer distance from the Wireless access point. A poor wireless signal will result in slow backups and dropped connections. If the client is on a wireless connection, check the signal strength. Swap ports and cables with a nearby client that is not experiencing network trouble or producing errors. Run Apple Disk Utility, which checks for directory corruption in the disk.Ĭonnect the machine to a different port on the hub. If backups work at other times, review what is happening at the original time on your network or on this client. Backing up the client computer at a different time may access the computer when it is not busy. Also, verify there is not an energy saver that turns off the client computer during the backup.Ĭhange the time of the script execution or rearrange the backup order of the clients. Restart the client Macintosh and try to back up again.Įnsure there are no unnecessary activities such as disk optimization, screen savers, or memory-intensive or processing-intensive applications running on the client during the backup. Firewall software, virus checking or file encryption utilities may cause problems. ![]() Finally, we outline several promising research directions that can serve as a guideline for future studies.Check for software conflicts. Next, we systematically categorize existing pre-trained GMs based on a taxonomy from four different perspectives including model architectures, pre-training strategies, tuning strategies, and applications. We first briefly present the limitations of molecular graph representation learning and thus introduce the motivation for molecular graph pre-training. In this paper, we provide a comprehensive survey of pre-trained GMs for molecular representations. The knowledge implicitly encoded in model parameters can benefit various downstream tasks and help to alleviate several fundamental challenges of molecular representation learning. To fully exploit the unlabeled molecular data, researchers first pre-train GNNs on large-scale molecular databases and then fine-tune these pre-trained Graph Models (GMs) in downstream tasks. Abstract: Recent years have witnessed remarkable advances in molecular representation learning using Graph Neural Networks (GNNs). ![]()
