#PJM -L jobenv=mck1 #PJM -L jobenv=mck1
(Optional, Fujitsu TCS only) Specify boot parameters
----------------------------------------------------
You can specify the boot parameters by defining environmental variables and pass them to Fujitsu TCS.
The parameters include the resource reservation settings, resource reservation amount, kernel arguments and routing of message channels between McKernel CPUs and Linux CPUs.
See `IHK Specifications - ihk_create_os_str() <spec/ihk.html>`__ for the parameter names and allowed values.
The example of setting the memory amount is shown below.

export IHK_MEM="7G@4,7G@5,7G@6,7G@7"
pjsub -X run.sh
