So the process is currently using 2.5GB - and then made a malloc request for 650MB - and this failed? How many 'tasks-per-node' are you using? Perhaps you need to reduce this number? https://www.nersc.gov/users/computational-systems/edison/configuration/ 64GB/node => 5.3GB/process for tasks-per-node=12 [and 2.6GB/node for tasks-per-node=24] Satish On Wed, 1 Feb 2017, Mark Adams wrote: > We are getting this error on Edison.
