cc -o answer c_slave.c -lpvm3
this creates the program answer in the current directory. Copy this program into the directory for goophy's PVM executables,
cp answer $HOME/pvm3/bin/ALPHA
cc -o answer c_slave.c -lpvm3
this creates the program answer in the current directory. We run a shared filesystem, so the current directory is the same on goophy and mango and the old program answer is overwritten by the new one. However the copy in $HOME/pvm3/bin/ALPHA is still there and this is the idea behind all this. Copy the new answer program into the directory for mango's PVM executables,
cp answer $HOME/pvm3/bin/RS6K
and we have two architecture specific programs with the same name in different directories where PVM will find them.
