[OMPI users] need help finding mpi for Raspberry pi Raspian Streach
I am starting to build a Raspberry pi cluster with MPI and I want to use the latest Raspian Streach Lite version from the raspberrypi.org website. After a lot of trials of watching youtubes on how to do this, I have found that the new version of Raspian Streach LITE is not compatible . I am looking for details instructions on how to install MPIwith this latest version of Raspian Streach Lite. I am using the newset hardware,RPI 3 B+ which requires this OS to use the features on the -new chipset Thanks Neil ___ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
Re: [OMPI users] need help finding mpi for Raspberry pi Raspian Stretch
ok here is a progress report. first I want to thank you both for getting me this far. gilles I think you were right about setting the CFLAGS and LDFLAGS =-march=armv6 it got to the first make command and after about an hour going good, It crashed when it started make 3. I was going to compress and post the config.log file , but I can not find it. I checked /var/log folder.can somebody please tell me where this is located?

Re: [OMPI users] need help installing mpi4py on openmpi
Kostas I guess we made some progress,however I think I still have a syntax problem. Right now I am still configuring the master node ,so I do not have a hostfile made yet.so I am using the following command which returns a python message from an unknown python program. mpirun --allow-run-as-root -np 4 hostname the responds is : python2helloworld.py python2helloworld.py python2helloworld.py python2helloworld.py this tells me that the program ran 4 times, 1 oer core. this is good. however I do not know where this program file is located. I also do not know how this python 2 file gets invoked . my question is :how can I modifly this command line to specifly the proper python program? thanks neil To: Open MPI Users Subject: Re: [OMPI users] need help installing mpi4py on openmpi Here are some instructions I have put together. I am using Python 2 and Open MPI 2.1.2 so I changed the commands to work for Python 3 and I tested them. Hope it helps.
