Hi Aamir, Due to lack of developer resources, MPICH no longer supports the Windows platform. Please refer to our FAQ for more information: http://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_Why_can… We recommend you use Microsoft MPI, which can be found here: http://msdn.microsoft.com/en-us/library/bb524831(v=vs.85).aspx — Huiwei Lu Postdoc Appointee Mathematics and Computer Science Division, Argonne National Laboratory http://www.mcs.anl.gov/~huiweilu/ > On Jan 5, 2015, at 4:06 PM, Aamir Faraz <AamirF(a)TechneDesignStudio.com> wrote: > > Hello, > > We would be installing LS-Dyna on our machines and require MPICH2 for that.

Hello, We would be installing LS-Dyna on our machines and require MPICH2 for that. Can you please send us the files so that we can run our files using MPI for our jobs as MPP. It's a windows XP that we have here.

Re: [mpich-discuss] Fwd: mpiexec.hydra creates unexpectable TCP socket.

When you pass -disable-auto-cleanup on the command line to mpiexec, you’re telling Hydra not to clean up other processes when one process in your job fails. It’s assumed that those processes will either clean themselves up or complete successfully. It’s not clear to me what your program is trying to do that would be erroneous, but usually when a process crashes, it’s the result of an erroneous program rather than a bug in MPICH. I’m not saying that there’s no bugs in MPICH, but we’d like to be able to narrow down where to look.

Fwd: mpiexec.hydra creates unexpectable TCP socket.
by Anatoly G 01 Jan '15

Dear MPICH. I have an additional information. This "strange configuration" (hydra connected to computer not from the list) is result of unhandled Main process fail (similar to abort() call) without killing children process (hydra). Thus I can see "init" process becomes a father of hydra process. Can you please refer me to document explaining hydra behavior when father process is dead (an emergency situation). I understand that this situation shouldn't happen and this bug will be fixed, but I'm curious about the hydra logic. Regards, Anatoly. ---------- Forwarded message ---------- From: Anatoly G <anatolyrishon(a)gmail.com> Date: Wed, Dec 24, 2014 at 1:00 PM Subject: mpiexec.hydra creates unexpectable TCP socket. To: discuss(a)mpich.org Dear MPICH. I'm using mpich 3.1 (hydra+MPI). I execute main application (Main) which calls mpiexec.hydra in following way: mpiexec.hydra -genvall -disable-auto-cleanup -f MpiConfigMachines.txt -launcher=ssh -n 3 MPI_Prog MpiConfigMachines.txt content: 10.3.2.100:1 10.3.2.101:2 Where 10.3.2.100 is a local host. As result I get - Main + single MPI_Prog processes on local computer - 2 MPI_Prog processes on remote one. Main application establish TCP socket with local MPI_Prog. Main application establish TCP socket with controller on other computer 10.3.2.170, which is not included in MpiConfigMachines.txt file. After executing some time (hours, sometimes days) I see via netstat that created new connection from mpiexec.hydra and controller. Before executing mpiexec.hydra I set environment variable setenv MPIEXEC_PORT_RANGE 50010:65535 According to manual this variable limits hydra destination ports to [50010:65535]. I see that hydra uses these ports with MPI_Prog, but connection with controller done on port 701 (controller computer). Controller program is a server. It can accept connections only. Can you please advice how to stand with this problem? How hydra recognizes controller IP and establish connection with it? Sincerely, Anatoly. _______________________________________________ discuss mailing list discuss(a)mpich.org To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
