Question

How can multiple pc_servers (such as, 6991, 6992, and 6993) be started automatically by aleph_startup?

Answer

By default just a single pc_server is started in aleph_start:

     setenv PC_SERVER_PORT 699${ALEPH_SUB_PORT}

To start multiple pc_servers, add the following lines to aleph_start.private:

     setenv PC_START_HOST "6991 6992 6993 6994 6995 6996 6997 6998"
     setenv PC_START_HOST "$PC_START_HOST 6999"

[Note:  This second line is necessary only if there are more than 8 pc_servers to be started.]

And change $alephe_root/aleph_startup as shown below:

        if  (! $?PC_START_HOST) then
            echo "starting pc_server... "
            csh -f $aleph_proc/pc_server $l_pc_server_port >& /dev/null &
            echo " "
        else
            foreach thishost ($PC_START_HOST)
               echo "starting pc_server... "  $thishost
               csh -f $aleph_proc/pc_server $thishost >& /dev/null &
               echo " "
            end
        endif
