1.  create the interactive job with salloc instead of srun

   salloc -N 1 -n X

   please refer to this page with more details about how to use salloc.
   
   
2. launch the second command with the flag --overlap
   

   srun -n X --overlap program
   
   

Note: if you use mpirun instead of srun to launch your program inside an interactive job allocating more than one node you will encounter the same error. If you would like/need to use mpirun on multiple nodes, you can follow the first solution above (salloc). On a single node, instead, the command will work (because in this last case mpirun does not call srun).
