Estimate of the capacity of all resources in GSIs batch system:

	D-Grid    14x4 =  56 Cores x 1321 SI2K =   74 KSi2K
	ALICE     24x8 = 192 Cores x 1479 SI2k =  284 KSi2k
	D-Grid    37x8 = 296 Cores x 1479 SI2k =  438 KSi2K
	D-Grid  7x16x8 = 896 Cores x 1972 SI2k = 1766 KSi2K
	                                        ------------
	                                         2567 KSi2K
	                                        ============
	
	Batch            600 Cores x 1500 SI2K =  900 KSi2K
	              --------                  ------------
	                 ~ 2k                    3467 kSi2K
	                                        ============

	3467 KSi2K x 24 hours x 30 days = 2496 MSi2K

2496 MSi2K capacity per month, [pledged by WLCG][2] 285 MSi2K net. KSi2K factor for the traditional part of the batch system are likely overrated with »1500 Si2K«. Resource distribution for the capacity in percent are D-Grid 67 %, ALICE 8 % and the old batch system 25 %.

**August 2008:**

	 150 khours (ALICE)
	  16 khours (others on D-Grid resources)
	------------
	 166 khours
	 281 khours (on the old batch farm, rest of GSI)
	------------
	 447 khours
	============

CPU hours capacity per month are ( 2076 Cores x 24 ) hours x 30 days = 1494 khours since september.

**September 2008:**

	 1494 khours
	- 903 khours (used from all queues and users/groups) 
	------------
	  597 khours (remaining free capacity)

Broken down to groups:

	  390 khours (ALICE)
	  230 khours (Theorie/Hades on D-Grid ressources)
	--------------
	  620 khours										68% 
	  283 khours (on the old batch farm, rest of GSI)   32%
	--------------
	  903 khours
