select/cray: update compile-time and runtime support for Cray build These changes update build support for Cray XT/XE: 1. renamed '--cray-xt' into '--cray' since also XE systems are supported; 2. autoconf rules to cover the various possible build cases: a) --enable-cray=off: HAVE_CRAY/HAVE_NATIVE_CRAY undefined, b) --enable-cray=on: HAVE_CRAY defined b1) local host is a native Cray system: HAVE_NATIVE_CRAY defined (requires installation of mysql-devel and libexpat-devel packages), b2) local host is not a native Cray system: the conditionally built parts (basil_interface.c, libalps.la) are not built; 3. updated configure logic: - since Cray support depends on mySQL, reordered tests in configure.ac, - reordered logic with regard to changes in (2), - an AM_CONDITIONAL to build native-Cray parts conditionally, - updated configure messages (XT/XE); 4. run-time read_conf test to ensure use of select/cray is properly supported, 5. an update of the NEWS file due to the change in (1) ==> may have a conflict in case you have a locally-updated copy. I have compile-tested the three possible scenarios in (2).

scontrol: warn user that base node state can not be changed on Cray The base node state (UP, DOWN, ALLOCATED, ...) is handled by ALPS and inferred from reading the output of ALPS inventory requests. To avoid inconsistencies, it is not possible for a user to alter this node state. This patch adds a warning to scontrol if a user wants to change node state through slurm: palu> scontrol update NodeName=nid00171 State=DOWN State=DOWN can not be changed through slurm: use native Cray tools such as e.g. xtprocadmin(8) The 'meta' states such as DRAIN can still be changed.

immediately before attempting to schedule jobs. 04_Cray-INVENTORY-directly-before-schedule.diff select/cray: do the inventory immediately before each schedule This puts the Basil inventory immediately before each (backfill) schedule. Having considered multiple alternatives, this is the most robust and least wasteful solution. The reason is that ALPS keeps internal node state, which can be changed * by the administrator (xtprocadmin), * by the node health checker programs (setting some nodes into 'suspect'), * by ALPS itself. Tracking this periodically, e.g. every HealthCheckInterval, may mean to miss some state changes. The result would not be a crash, but a subsequently failed ALPS reservation, which would require to undo some of the slurm state. FIXME: since we are not using this, we have not yet considered wiki/wiki2. Possible places to update these are: - run periodic checkes every HealthCheckInterval (sub-optimal), - change plugins/sched/wiki{,2}/get_nodes.c

XT/XE systems, and build on native Cray XT/XE systems (auto-detected).

03_Cray-BASIL-node-ranking.diff select/cray: perform node ranking This supplies the select function-pointer to request a reordering of nodes based on the current Cray node ordering. The Cray node ordering is set internally via the ALPS_NIDORDER configuration variables that controls the way ALPS considers nodes. This ordering in turn determines the order of nodes as the appear subsequently in the Inventory output. The present patch exploits this fact and uses an auto-incrementing number to reflect the node ranking (counting is reversed since the parser returns the nodes in stack/LIFO order). The node ranking is performed on slurmctld (re-)configuration, hence the tests are more stringent: exit if Inventory fails (this condition is extremely rare) and if no nodes are powered up (also a condition that can be cured by restarting slurmctld only when the system is ready).
