Jetstream allocations are measured in XSEDE Service Units (SUs). On Jetstream, SUs are consumed at a rate of 1 SU per vCPU_core-hour (use of one virtual core of a CPU per hour).
The SU cost rate per hour for each Jetstream VM size is outlined in Virtual Machine Sizes and Configurations.
Currently, only instances that have an green status light decrement SUs at the full rate.
Starting October 1, 2018:
SUSPENDED instances will be decremented only 0.75 SUs per vCPU_core-hour (75%).
STOPPED instances will be decremented only 0.50 SUs per vCPU_core-hour (50%).
SHELVED instances will not be decremented SUs. (0%)
ACTIVE-DEPLOYING instances will not be decremented SUs. (0%)
