COMPUTATIONAL STORAGE DEVICE AND METHOD OF OPERATING THE SAME

An operating method of a computational storage device includes: setting a first computing namespace, including a first queue and a first accelerator and having a first value as its first ID, per instructions from a first host; setting a second computing namespace, including a second queue and a second accelerator and having a second value as its first ID, per instructions from a second host; loading a first program from the first host in the first computing namespace; loading a second program from the second host in the second computing namespace; setting a second ID of the first computing namespace to a third value based on an ID of the first program per instructions to activate the first program; and setting the second ID of the second computing namespace to a fourth value based on an ID of the second program per instructions to activate the second program.
