slurm error

Hello everyone: I submitted a job via slurm and got this error: Error: cannot allocate vector of size 7.8 Gb Execution halted Warning message: system call failed: Cannot allocate memory I have run this job but my job got terminated and the error was this. Can anyone tell me how to solve this? I am running R job via sbatch.

You need to provide more details:

What is your slurm job specifications? How big are your data?

This error looks like R complaining not having enough memory to allocate the required data. Increasing your slurm batch job memory requirement to like 20G might help. But there's no way for us to know unless you provide more information.

You are not specifying any memory allocation in your SLURM file. You need to add (change the number as needed)

#SBATCH --mem=20g

Without this directive you are likely getting the default memory allocation which is smaller than 8G your program wants to have.

I included this line: #SBATCH --mem=20g and now while running sbatch scriptname. I am getting this error: sbatch: error: Memory specification can not be satisfied sbatch: error: Batch job submission failed: Requested node configuration is not available

You will need to check with local cluster admins to see how you can get more memory for your job. Depending on your SLURM setup you may need to submit to some specific partition or ask for more cores etc.

Okay. I will do that. Thank you so much for helping
