Jen, Can you submit a job to a specific queue and get the correct resources (i.e. with "#PBS -q altix" as a PBS directive in your script, do you get altix nodes)? --Joe

Hi All, I am not sure if this is a torque or Maui question, so please forgive the crosspost. :} I used to do this blissfully boringly using acl_hosts. Something has changed and this is not working anymore between torque 2.1.x and now. I have the following: torque 2.3.5 maui 3.2.6p21 I have a large cluster with several departments and these departments want to use the nodes they purchased. In the past, I set up a queue for each of these departments and I assigned nodes to the queues in torque. Has the way to do this changed? I have seen several messages lately from folks no longer able to get it to work... I am not married to this method and will happily implement any method that will keep my (hundreds) of users separated and on their own nodes. I do not want them to have to change their scripts. These are heterogeneous, too, so it is not just a policy thing - the infiniband jobs won't run on the non IB nodes, and the some are 8proc, some are 2, etc. I have tried the "neednodes" method. It did nothing. I've been trying to do partitions in Maui and that seems to be ignored as well. This is a 64 bit system, by the way. Can anyone point me to modern documentation on how to partition the nodes? I tried defining attributes in "nodes" under server_priv: node74 np=2 noib node75 np=2 noib node76 np=2 altix node77 np=8 altix node78 np=8 hiio And then I have in my torque config, something like: # Create and define esmg08q create queue esmg08q set queue esmg08q queue_type = Execution set queue esmg08q resources_max.cput = 10000:00:00 set queue esmg08q resources_max.ncpus = 179 set queue esmg08q resources_max.nodect = 22 set queue esmg08q resources_max.walltime = 10000:00:00 set queue esmg08q resources_min.cput = 00:00:01 set queue esmg08q resources_min.ncpus = 1 set queue esmg08q resources_min.nodect = 1 set queue esmg08q resources_default.neednodes=altix set queue esmg08q resources_min.walltime = 00:00:01 set queue esmg08q resources_default.cput = 10000:00:00 set queue esmg08q resources_default.ncpus = 8 set queue esmg08q resources_default.walltime = 100:00:00 set queue esmg08q acl_logic_or = true set queue esmg08q acl_groups = esmg set queue esmg08q acl_groups += admin set queue esmg08q acl_group_sloppy = true set queue esmg08q acl_group_enable = true set queue esmg08q enabled = True set queue esmg08q started = True - From this I see in maui a line in showconfig: maui]# /usr/local/maui/bin/showconfig | grep esmg CLASSCFG[esmg08q] DEFAULT.FEATURES=[altix] So I was hopeful! But it ignores it and doesn't assign the nodes with the altix attribute? No matter what I do, I always get the first nodes and in order. Like it is reading from a machine file that I don't know about... I do get 8 proc nodes if I ask for nodes with 8 processors, I do get whatever node I ask for in my submit script. I literally lets me request any node I want, no matter which user I am or which queue I submit to. Does anyone have any ideas?
