1 HPC Archeticture
- Whats the point of an High Performance Computing cluster?
An analogy:
- Lets compare it to a large hotel.
- What if there was no reservation system and no front desk? everyone just walks to a room? Chaos.
To continue with our analogy:
- headnode/submit nodes == the hotel front desk or online reservation site
- compute nodes == The hotel rooms
- submitting a job == asking for a room
- How many days? how many beds? == how long the job will run, how many cores?
- Showing up at the front desk and getting your room key == your job is ready to run
- Maybe the hotel was busy and you had to wait for the room to be cleaned == maybe you had to wait for resources to free up
- Checkout, you turn in your keys and leave the hotel == Your job has finished and you longer have access to the compute node anymore.
Lets review the parts of an HPC cluster.
