Author Topic: Nodes launched under windows 10 not visible in admin-ui - but are active  (Read 259 times)

Firstly - thanks for this great framework - been spending my Christmas break playing with it and having great fun!

The issue I'm trying to resolve is that I am seeing that there are nodes that are being launched from windows that are not visible in the admin-ui - but are nonetheless being use when i launch a calculation.

I've got 3 raspberry pi cards and a Windows 10 laptop.  On the first of the raspberrypi-00 i run the driver and on raspberrypi-01 and -02 i am running one node each.  I'm using the n-body sample program - I'm launching the client from windows using ant run. 

I've modified the config file to have a lot of bodies (25000) and to use 125 bodies per task so that there are 200 tasks per job.   I reduced the number of time steps to 10 so that i get a nice round number of 2000 jobs total to run to make it easy to check that all tasks have run in the end.

When i run client like this i always see it finish with 2000 tasks completed and it takes around 2 minutes to complete.

However, i then launch some nodes from the windows machine.  They report connection success (see below).  But when i look at admin-ui it still shows only 2 nodes connected.  But when i run the client again (after resetting task counts and server statistics on admin-ui) it completes in less time and the number of tasks executed are less than 2000 - the "invisible" nodes are being used.....

I initially had trouble getting the nodes to connect when using discovery, so it set it to false and then claimed to connect, but admin-ui is failing to see them although they are part of the network.  I've atteched the and the

Again, greatly enjoying using the tool but am just wondering if i'm misconfiguring something here or if i've maybe uncovered a bug.
