Mpiexec Machinefile
child process launched by mpiexec. I am using "system()" to call the mpiexec process from the child process. I am using mpich2-1.4.1 and the hydra process manger. The errors I see are below. I mpiexec command not found am attaching the source file main.c. Let me know what I am doing wrong here and if you need more information. To compile: /home/install/mpich/mpich2-1.4.1/linux_x86_64//bin/mpicc main.c -I/home/install/mpich/mpich2-1.4.1/linux_x86_64/include When I run the test on multiple nodes I get the following errors: mpiexec -n 3 -f hosts.list a.out proxy:0:0@machine3] HYDU_create_process (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/utils/launch/launch.c:36): dup2 error (Bad file descriptor) [proxy:0:0@machine3] launch_procs (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/pm/pmiserv/pmip_cb.c:751): create process returned error [proxy:0:0@machine3] HYD_pmcd_pmip_control_cmd_cb (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/pm/pmiserv/pmip_cb.c:935): launch_procs returned error [proxy:0:0@machine3] HYDT_dmxu_poll_wait_for_event (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/tools/demux/demux_poll.c:77): callback returned error status [proxy:0:0@machine3] main (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/pm/pmiserv/pmip.c:226): demux engine error waiting for event [mpiexec@machine1.abc.com] control_cb (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/pm/pmiserv/pmiserv_cb.c:215): assert (!closed) failed [mpiexec@machine1.abc.com] HYDT_dmxu_poll_wait_for_event (/home/install/mpich/src/mpich2-1.4.1/src/pm/hydra/tools/demux/demux_poll.c:77): callback returned error status [mpiexec@machine1.abc.com] HYD_pmci_wait_for_completion (/home/inst

--help ] [ --usage ] [ --extendedhelp ] [ --extendedusage ] [ --debughelp ] [ --debugusage ] [ --commhelp ] [ --commusage ]Description The mpiexec command is the typical way https://trac.mpich.org/projects/mpich/ticket/1539 to start parallel or serial jobs. It hides the differences of starting jobs of various implementations of the Message Passing Interface, version 2, from the user. Within the ParaStation MPI implementation of this command, the startup of parallel jobs is handled as described by the process_placement(7) manual page. The process spawning may also be steered by environment variables which are described http://docs.par-tec.com/html/psmpi-userguide/rn01re01.html in detail within ps_environment(7). This version of mpiexec supports the Process Manager Interface (PMI) protocol. Therefore, this version of mpiexec also supports many other implementations of MPI2, like MPICH2, MVAPICH2 or Intel MPI. The command mpiexec is typically used like mpiexec -np num prog [args] This will start up the program prog num times in parallel forming a parallel job. Args are optional arguments which will be passed to each task. Prog is not necessarily required to use MPI calls to transfer data. To run a serial job, aka a job consisting only of a single task, use a task count of 1, e.g. mpiexec -np 1 prog [args]OptionsGeneral options -n num
, -np num
, --np num
, --np=num
Specify the number of processes to start. -e , --exports=envlist
Name or comma-separated list of environment variable(s) exported to all processes. -x , --envall Export all environment variables to all processes. -E , --env name
value Export the variable name with the content value. -b , --bnr Enable ParaStation4 compatibility mode. -a , --jobalias=name

(I): Information, (W): Warning, (E): Error mpiexec : (I) JOBTYPE = jobtype Cause: jobtypeis specified as a job type. Action: No specific action is required. However, if error in the job type differs from that the user specified, terminate the mpiexec command, set the correct job type and then reexecute the command. mpiexec : (E) Illegal JOBTYPE (jobtype) Cause: An invalid jobtype is specified as a job type. The mpiexec command terminates. Action: Specify the correct value in the JOBTYPE environment variable and then reexecute the command. mpiexec : error in system (W) mpiexec is not process group (ID = pgrp_id) leader Cause: The mpiexec command is not the leader of the process group that has pgrp_id. Therefore, forced termination of the job by the mpiexec command does not influence processes that are dynamically generated. Action: To continue the command execution when the mpiexec command forcibly terminates the job, check whether there are any remaining processes. If any processes remain, use the kill command to terminate them. Alternatively, pause the command execution and then reexecute it in an environment in which the mpiexec command can be the leader of the process group. mpiexec : (E) file_name may not exist Cause: file_name is specified as a configuration file but this file does not exist. Alternatively, the reference to this file is rejected. The mpiexec command terminates. Action: Specify the correct file name to -configfile and reexecute the command. mpiexec : (E) file_name (line_no) : EOF within the continued line Cause: An EOF is detected within a continued line of line_no in the file_name configuration file. The mpiexec command terminates. Action: Corr

We got the software compiled and it runs nicely under Windows. However, certain models it is required that two models are solved at the same time. We have solved this in a way that the first parallel run makes on certain positions of the algorithm system calls to start a second parallel run forsolving the second model. After the second model has been solved, information for the first model is updated and the first parallel run continues to solve on the first model. This process continues until both models are solved.When the second model solver is called the following error occures:[01:5952]...ERROR:Error while connecting to host, No connection could be made because the target machine actively refused it. (10061)mpiexec aborting job...The first program is started with command mpiexec -localroot -n 2 path\\program.exe < directivefile > output.logWithin the program the second model is calledvmrunint=system("solve_2ndmodel.bat")and we also tried systemqq() without success.Within that .bat -file among other things the second model solver is started with command:mpiexec -localroot -n 2 path\\program.exe< directivefileThe executable is same but it is working in with different data. This system works perfectly in linux. And we hope that it is pos
