9/27/2023 0 Comments Mathematica raspberry pi 4![]() ![]() ![]() ![]() I am using the pi user account on both computers. I have enabled ssh on each RPi through raspi-config. Additionally, I have followed these directions for setting up the avahi daemon on each RPi, so that I can refer to them by hostname rather than IP address. I do not have a VPN interfering with communication between the RPis. No firewall exists between the two RPis and each can ping one another. Both computers are running the latest version of Mathematica for the RPi (as if this writing $Version is Februand uname -a is 3.18.7-v7+ for coruscant and 3.18.7+ for lcdlab.). The local RPi is a version 2 board (4 cores) with the name of coruscant and the remote RPi is a model B with the name lcdlab. I think this is feasible in the present case since we are restricting ourselves to one version of Mathematica on one platform (the RPi). Also, is the -LinkHost the frontend machine, or the kernel machine? If a frontend hosts a kernel or a kernel hosts a frontend seems up for semantic discussion.) Neither writing out the local Pi ip address or the remote Pi ip address in -LinkHost ipaddres solved the problem.Īny suggestions would be greatly appreciated!īecause there seems to be no quality resource or documentation on this subject, I will attempt to provide as close of a hand-holding solution as possible. ![]() (I am also confused about the posts and documentation writing the ipaddress sometimes with one, sometimes with two 's'. I also found this old post suggesting I write out the ip address in the -LinkHost ipaddres. The local Pi is a Raspberry Pi 2, the remote one is an older Raspberry Pi. replacing the default 'wolframssh' with 'mathssh' and the -wstp option with -mathlink), but this didn't help. I tried fiddling with the advanced options (e.g. I have both Pi's on my LAN, and am sure the ip addresses are correct and visible (I am remote controlling them from my PC with a VNC remote desktop program and can login to the remote Pi via ssh from my local Pi.). You should try running the kernel connection outside front end. I followed the instructions in this howto from wolfram, but I keep getting the error: The kernel New Kernel failed to connect to the front end. ![]()
