#2204: Compilation on comet failed to due out of memory
---------------------------------+------------------------
 Reporter:  Roland Haas          |       Type:  defect
   Status:  new                  |   Priority:  minor
Milestone:                       |  Component:  SimFactory
  Version:  development version  |   Keywords:  comet
---------------------------------+------------------------
 Compiling on Comet's login node failed for me when compiling
 {{{
 arrangements/Carpet/CarpetLib/src/restrict_3d_cc_o5_rf2.cc
 }}}
 due to an out of memory error. ulimit -a indicates that there is a limit
 of 4GB per user
 {{{
 rhaas at comet-ln2:~$ ulimit -a

 which can be avoided by going to a compute node
 {{{
 srun --partition=debug --pty --nodes=1 --ntasks-per-node=24 -t 00:30:00
 --wait=0 --export=ALL /bin/bash
 }}}
 and compiling via
 {{{
 simfactory/bin/sim build --machine comet
 }}}

 This is (hopefully) a temporary measure on comet.
