Hello Dov, The good people at McGill would like to begin ingesting your GEM output. The contact and machine info are: John Gyakum address@hidden maelstrom2.meteo.mcgill.ca 132.206.43.30 John, Do you have a phone number for our records as well. Our records currently indicate that N.Bao address@hidden ph:TBA is running the LDM on maelstrom.meteo.mcgill.ca Can you let us know if this is still an active LDM machine: (jweber) lenny:/home/www/projects/idd 9 % ldmping maelstrom.meteo.mcgill.ca Sep 06 21:46:33 State Elapsed Port Remote_Host rpc_stat Sep 06 21:46:34 SVC_UNAVAIL 0.150542 0 maelstrom.meteo.mcgill.ca RPC: Program not registered It currently is not running.....
