ITS Systems Charging

| CPU Rate || $1.00 per CPU Hour
|1800-0800 & weekends|| $0.50 per CPU Hour
| Disk Storage (current): || $0.035/MB/day
| Disk Storage (May 1): ||$0.005/MB/day|
Users can elect to be charged in either of two different ways:
- By hourly use.
- By the Cray Fair Share method.
| Peak (daily) || $10 per processor-hour
| Off-Peak (1800-0600) || $5 per processor-hour
Hourly users are allocated one share in order to use the
Cray Fair Share priority allocation method, but will be billed
at the hourly rate.
Fair Share Method (operational May 1)
UWO has implemented the Cray "Fair Share Method" for charging.
Users may buy shares, and then job priorities are allocated
according to the user's proportion of currently active shares.
Additionally heavy-users during one weekly period will have
their relative priority downgraded for the next period.
Shares are available at a cost of $500 per share per year. External users
may not buy more than 10 shares.
Shares are valid for one year starting on May 1.
NO charge for local disk -- to be used for scratch space (not
VAX/VMS System (uwovax.uwo.ca)
| Base rate || $70/CPU-hour
| 1800-0800 & weekends || $35/CPU-hour
| Low priority batch || $14/CPU-hour
| Disk Storage || $035/MB/day
| Disk Storage (May 1): || $0.025/MB/day
The Near Future
Lowering disk charges by May 1 to $2/MB/yr (7x reduction from
current rates). VAX rates will be reduced slightly from $.035/MB/day
to $.025/MB/day since that machine is close to capacity and we don't
want to have to upgrade it.
All students (September 1997) and eventually all faculty
and staff as well will automatically be provided with accounts
probably with a fairly low disk quota and something like $2 to be
spent on CPU, disk space and/or printing. Information services
programs like email, lynx and ftp will continue to be "free".
Project accounts will probably be set up in a similar
way with some minimal amount of funds, pre-deposited.
Shares on hpc (available May 1, 1997)
are definitely the cheap way to get computing done on the Cray.
