Hi, With "FastSchedule=1" in two cases, the second job wait the end of the first job. But in my script I need to remove the parameter : #SBATCH --mem=2048 else I have this error
sbatch: error: Memory specification can not be satisfied sbatch: error: Batch job submission failed: Requested node configuration is not available I try the other solutions that you give me, and I tell you what happens. PS : I'm sorry, but my English is not very good.

What ever you post about your partitions resource configuration, it is not taken into considerations. I think I could construct a case very your behaviour is fine considering your _actual configuration_ and not your _configured resources_ https://computing.llnl.gov/linux/slurm/slurm.conf.html There section *FastSchedule* <--- %< ---> 0 Base scheduling decisions upon the actual configuration of each individual node except that the node's processor count in SLURM's configuration must match the actual hardware configuration if SchedulerType=sched/gang or SelectType=select/cons_res are configured (both of those plugins maintain resource allocation information using bitmaps for the cores in the system and must remain static, while the node's memory and disk space can be established later). <--- %< ---> Regards, Benjamin -- FSU Jena | JULIELab.de/Staff/Benjamin+Redling.html vox: +49 3641 9 44323 | fax: +49 3641 9 44321
