Error Message

[mpiexec@node00] HYD_sock_write (../../../../../src/pm/i_hydra/libhydra/sock/hydra_sock_intel.c:353): write error (Bad file descriptor) [mpiexec@node00] cmd_bcast_root (../../../../../src/pm/i_hydra/mpiexec/mpiexec.c:147): error sending cwd cmd to proxy [mpiexec@node00] stdin_cb (../../../../../src/pm/i_hydra/mpiexec/mpiexec.c:324): unable to send response downstream [mpiexec@node00] HYDI_dmx_poll_wait_for_event (../../../../../src/pm/i_hydra/libhydra/demux/hydra_demux_poll.c:79): callback returned error status [mpiexec@node00] main (../../../../../src/pm/i_hydra/mpiexec/mpiexec.c:2064): error waiting for event
[mpiexec@host1] wait_proxies_to_terminate (../../../../../src/pm/i_hydra/mpiexec/intel/i_mpiexec.c:389): downstream from host host2 exited with status 255


The remote
process is unavailable due to:
  • the host reboot;
  • an unexpected signal received;
  • out-of-memory manager (OOM) errors;
  • job termination by the Job Scheduler (PBS Pro*,  SLURM*) in case of resources limitation (for example, walltime or cputime limitation).


  1. Check the system log files.
  2. Try to find the reason of the
    process termination and fix the issue.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
