salloc(1) --time=1:0:0 --cpus-per-task=8 --mem=10g
Obtain a SLURM job allocation (a set of nodes), execute a command, and then release the allocation when the command is finished
-t, --time=<time>
       Set a limit on the total run time of the job allocation.  If the requested time limit exceeds  the
       partition's  time  limit,  the  job  will be left in a PENDING state (possibly indefinitely).  The
       default time limit is the partition's time limit.  When the time limit is reached, the  each  task
       in each job step is sent SIGTERM followed by SIGKILL. The interval between signals is specified by
       the SLURM configuration parameter KillWait.  A time limit of zero requests that no time  limit  be
       imposed.   Acceptable  time formats include "minutes", "minutes:seconds", "hours:minutes:seconds",
       "days-hours", "days-hours:minutes" and "days-hours:minutes:seconds".
-c, --cpus-per-task=<ncpus>
       Advise the SLURM controller that ensuing job steps will require ncpus  number  of  processors  per
       task.  Without this option, the controller will just try to allocate one processor per task.

       For  instance,  consider  an  application  that  has 4 tasks, each requiring 3 processors.  If our
       cluster is comprised of quad-processors nodes and we simply ask for 12 processors, the  controller
       might give us only 3 nodes.  However, by using the --cpus-per-task=3 options, the controller knows
       that each task requires 3 processors on the same node, and the controller will grant an allocation
       of 4 nodes, one for each of the 4 tasks.
       Specify  the  real  memory required per node in MegaBytes.  Default value is DefMemPerNode and the
       maximum value is MaxMemPerNode. If configured, both of parameters can be seen using  the  scontrol
       show  config command.  This parameter would generally be used if whole nodes are allocated to jobs
       (SelectType=select/linear).   Also  see  --mem-per-cpu.   --mem  and  --mem-per-cpu  are  mutually
