Hi,

this is due to the environment setting in $TWISTER_HOME/bin/twister.properties, the following three lines must use full path:

For example :

nodes_file = /N/u/train182/Twister/bin/nodes   -> where I think in your setting should be "$TWISTER_HOME/bin/nodes" which is not supported.

app_dir = /N/u/train182/Twister/apps

data_dir = /N/u/train182/Twister/data 

Best,
Stephen

indeed, didn't notice #!/bin/bash wasn't buried along with the disclaimer comments...boo!

why not generate that file with start_twister.sh?  afterall, the num of deamons/works must match, the $TWISTER_HOME var has already been set by the user, the bin/apps/data folders are default, and the port should work by default (or again, have user edit start_twister.sh).

It doesn't make any sense to set vars manually in that file imo when we're already exporting them... well, I just edited my start_twister.sh script and added this to the bottom:

I also edited the copyright.txt file to bash commented, not java/c++ commenting.
