Hi, Thanks. Problem is resolved.
Nodes were able to do SSH But it was unable to ping each other. It worked. Thanks. -----Original Message----- From: Reuti [mailto:re...@staff.uni-marburg.de] Sent: Thursday, September 29, 2016 6:39 PM To: Aditi - (India & ME - HLS) <aditi...@wipro.com> Cc: users@gridengine.org Subject: Re: [gridengine users] Executing task of Job failed; failed sending task to execd; can't find connection ** This mail has been sent from an external source ** Hi, > Am 29.09.2016 um 14:41 schrieb <aditi...@wipro.com> <aditi...@wipro.com>: > > Hi, > > I am trying to run a Job on parallel nodes using openmpi1.4.5 Better would be Open MPI 1.6.5. Nevertheless the questions are: - Was Open MPI compiled with SGE integration, i.e. something like: $ ompi_info | grep grid MCA ras: gridengine (MCA v2.0, API v2.0, Component v1.6.5) - Did you request a PE in the submission and how is this PE set up? - How does the `mpiexec` line in your jobscript look like? - All nodes can talk to each other directly? > and ge2011.11, job goes in Running state and then gets aborted. > After Job gets aborted, I get following error message on the primary node: > > error: executing task of job 28561 failed: failed sending task to > ex...@punehpcdl01.wiprohpc.com: can't find connection > > Or > > error: executing task of job 28560 failed: failed sending task to > ex...@punehpcdl01.wiprohpc.com: can't find connection > ---------------------------------------------------------------------- > ---- A daemon (pid 20651) died unexpectedly with status 1 while > attempting to launch so we are aborting. > > There may be more information reported by the environment (see above). > > This may be because the daemon was unable to find all the needed > shared libraries on the remote node.
