[Triolith-users] Triolith pilot test news 2012-07-06

[Mats Kronberg]

Dear Triolith user,

Some news regarding the pilot test since my last email:

+ More compute nodes are now available to users (currently 215 of
  240 nodes are available).

+ The "fat" nodes are now available (in total Triolith will have 56
  fat nodes with 128GB RAM each, 47 of these are available right
  now). You can use them by requesting a certain amount of memory
  for your job (e.g "--mem=127000").

+ The planned service stop on Monday is cancelled. There are no
  further stops planned for the next couple of weeks, but we may stop
  some or all nodes on short notice if this is needed to address any
  unexpected technical problems.

+ The User Guide has been updated:
  http://www.nsc.liu.se/systems/triolith/

+ The "module" command is now available from job scripts (if they are
  written in bash, csh or tcsh). If you use sh or ksh you can use
  "module" if you add one line to your script (this is documented in
  the User Guide).

+ More software has been installed (see "module avail")

+ Triolith has been added to the NSC Status Display
  http://www.nsc.liu.se/status/ and
  http://www.nsc.liu.se/cgi-bin/triolithstatus

+ There are four nodes available for short development/test jobs. Add
  "--reservation=devel" and request less than one hour of wall time
  (e.g "-t 00:30:00") to use them. Since most other nodes are
  currently busy running jobs, if you need to quickly test something,
  using the development nodes will usually give you the shortest queue
  time.

If you have any feedback regarding how the system works so far (what
works, what doesn't work, benchmark results etc), please send it to us
(support at nsc.liu.se or reply to this email).
