I am running a VQE calculation running from a cluster using nohup.

However, some of my jobs keep hanging with 'creating' and therefore my VQE is not converging/not working.

However, at the same time, a subset of my jobs are still running.

Please, can you help me diagnose the problem?

Here is a selection of Job IDs of the 63 (at present) hanging jobs:




  • $\begingroup$ Hello, can you see these jobs in the IBM Q Experience? It might be the case that it is just taking a long time to execute as the queue is long. $\endgroup$

  • $\begingroup$ I don't think this is the case. Because every time I runs a job one is ran and one stays in my pending as creating. So jobs are still running. But some also appear to be hanging. When they all should be running $\endgroup$

  • $\begingroup$ Sometimes I face similar problem. For example, I sent a few jobs to one quantum processor and some of them were simply skiped and indicated as pending. Moreover, I was able to run other jobs on this quantum processor while the previous were still pending. So, it seemed like IBM Q simply does not know about these jobs. I simply cancelled hanged jobs and sent them again. $\endgroup$ Nov 9 '19 at 22:27
