Re: [OMPI users] successful story of building openmpi on cygwin?

Hi, Shiqing Thanks for the info. Usually I code in cygwin on my PC and move the code to clusters later. So I try to setup openmpi on cygwin. Best -- Yue On Fri, Oct 28, 2011 at 6:09 AM, Shiqing Fan wrote: > Hi Yue, > > If you want to build Open MPI on Windows, there is another way by using > C

[OMPI users] How to override default hostfile to specify host

Hi, If I use "orterun -H " and does not belong in the default hostfile ("etc/openmpi-default-hostfile"), openmpi gives an error. Is there an easy way to get the aforementioned command to work without specifying a different hostfile with in it? Thank you.

I have been trying to build with mingw, including mingw32-gfortran, with no luck. Using mingw32-4.5.1, openmpi-1.5.4. Has anyone gotten mingw32 with gfortran to work with openmpi? ThxJohn On 10/28/11 4:09 AM, Shiqing Fan wrote: Hi Yue, If you want to build Open MPI on Windows, there is

Re: [OMPI users] Problem launching application on windows

Hi Shiqing, Unfortunately that did not solve the problem. Can you tell me something more about how the sockets work and how they could get corrupted? Maybe I can figure out what is going wrong. Thanks From: Shiqing Fan [mailto:f...@hlrs.de] Sent: Frid

Re: [OMPI users] Problem launching application on windows

Hi, This looks not normal, because this error might happen mainly by improper sockets. I don't have any clue at moment, as I can't reproduce it. Could you try to reinstall Open MPI? And make sure there is no other installation on your system. If this is still not working, try using Open MPI

Re: [OMPI users] successful story of building openmpi on cygwin?

Hi Yue, If you want to build Open MPI on Windows, there is another way by using CMake and Visual Studio, take a look into the windows readme file in the source root. If you want to use the GNU compilers, you might also use CMake with MinGW. But the MinGW support is only basically supported.

Re: [OMPI users] Hybrid MPI/Pthreads program behaves differently on two different machines with same hardware (solved)

After trying several kernel versions. The problem is narrowed down to the change from kernel 2.6.22 to 2.6.23. Finally I find the big change in process scheduler in 2.6.23: the Completely Fair Scheduler. http://kernelnewbies.org/Linux_2_6_23#head-f3a847a5aace97932f838027c93121321a6499e7
