Suppression of classes in BQS

2 October 2006

We have scheduled to suppress classes in BQS service, only classes defined in the list under are going to be kept.

Name CPUDef CPUMax MemDef MemMax ScratchDef ScratchMax Restricted
A 5000 10000 128 512 400 5150 no
G 170000 500000 256 1024 1025 10250 no
J 500000 1400000 256 -1 2050 -1 yes
P 400000 1000000 256 2048 1025 36000 yes
T 800000 2000000 512 2048 2050 20500 no
V 7350 160000 64 512 100 1025 yes
W 1400000 3300000 512 2048 2050 30750 yes

In point of fact we group the existing classes :
- A,C become A but with the limits of actual C class
- G,I become G but with tle limits of actual I class
- R,S,T become T. The differentiation between IOB and CPUB are no more used.

We plan two steps :
- 10/02/2006 : we change the limits of classes which will be suppressed, as they will be equal to those which will be kept in the future.
- 11/06/2006 : we suppress C, I, R and S classes.
WARNING : from this time onwards, qsub command will fail if you ask one of these classes.

We strongly advise you to ask all the needed resources on qsub command : cpu, memory, scratch and spool, and not to choise a class, BQS will affect the most appropriate class according to the asked resources. Only restricted classes have to be asked on qsub command.
