Dear QE users, I want to plot a fermi surface with a very dense kpoints, so that I can do some calculation such as the Fermi surface nesting function. A smaller kpoints number, such as 1200, works fine. But when I take the nscf calculation with a large kpoints number, such as 2000, the error happens as forllowing:
[proxy:0:0 at node6] HYD_pmcd_pmip_control_cmd_cb (./pm/pmiserv/pmip_cb.c:939): process reading stdin too slowly; can't keep up [proxy:0:0 at node6] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status [proxy:0:0 at node6] main (./pm/pmiserv/pmip.c:206): demux engine error waiting for event [mpiexec at node0] control_cb (./pm/pmiserv/pmiserv_cb.c:202): assert (!closed) failed [mpiexec at node0] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:77): callback returned error status [mpiexec at node0] HYD_pmci_wait_for_completion (./pm/pmiserv/pmiserv_pmci.c:197): error waiting for event [mpiexec at node0] main (./ui/mpich/mpiexec.c:331): process manager error waiting for completion Does anybody know what is the porblem?
