Hello, An issue with certain jobs that use the Ubuntu 18 image on gpsc[78] are causing nodes to fail. Access to the Ubuntu 18.04 job image has been temporarily disabled until we determine the cause of the node errors. To those users who have Ubuntu 18.04 jobs on gpsc[78] that have failed in the last day: * If you use hpcx, could you please make sure that the version you load in your jobs are . ssmuse-sh -x main/opt/openmpi/openmpi-4.1.2rc4--hpcx-2.10-mofed-5.x-gcc * Let me know when you have made this change. Afterwards, you will be given access to the Ubuntu 18.04 image to try running it again. * If your jobs do not use hpcx, please let me know. To those users who have Ubuntu 18.04 jobs on gpsc[78], but whose jobs have not failed in the last day, please let me know who you are. Our apologies for this disruption. Thank you, Dale Mowbray
