The T0 load generator will run at "peak" rate for 3 days ("peak" rate means data from 24h/day of detector data taking at 200Hz are distributed in 24h, while "nominal" rate means data from 14 hours/day of detector data taking at 200Hz are distributed in 24h).

At peak rate 17,280,000 events/day are produced, corresponding to 27.6 TB/day of RAW, 17.3 TB/day of ESD and ~~3.5 TB/day~~ of AOD (considering the sizes of 1.6 MB/event for RAW, 1.0 MB/event for ESD and ~~0.2 MB/event for AOD~~)

It turned out that AOD size was 0.1 MB/event; 1.7TB/day.

T0-T1(LYON)

Shipping continuously data to T1s according to computing model, sites should demonstrate to sustain for 3 days the following export rates

SITE	TAPE	DISK	TOTAL
IN2P3	48.00 MB/s	100.00 MB/s	148.00 MB/s

Metric for success: Sites should be capable of sustaining 90% of the mentioned rates (for both disk and tape) for at least 2 days of test. For sites who would like to test higher throughput, we can oversubscribe (both to disk and tape).

As a reminder, here the table of the necessary space needed at each T1

SITE	TAPE	DISK

T2s will receive AODs, which should be generated at a rate of ~~3.5TB/day~~ 1.7TB/day. The amount that each site receives depends on the share as written in https://twiki.cern.ch/twiki/bin/view/Atlas/DDMOperationsGroup#CCRC08_2_May_2008

T0-T1 transfers are proceeding, No T1-T2 transfers to DATADISK since last night.

according to dq2.log, new subscriptions today (since 5.22 00:00) are queued only to BEIJING and RO-02-NIPNE, resulting in errors.

the status table does not look nice, I will check. http://panda.atlascomp.org/?mode=listFunctionalTests&testType=T1toT2s#LYON

apparently, no subscription to LAPP, CPPM, LPSC. TOKYO and LAL, who are assigned larger shares, have less subscriptions.

Erming:

 I tuned the IN2P3-BEIJING channel to 20 concurrent files and 5 concurrent streams. I tested many combinations:
 Nofiles   NoStreams
 5            3
 10           5
 15           5

 25           5
 30           5
 
 It appears that 20/5 is the best for the moment which can reach more than 80MB/s throughput.

30 May 9h00: The plan was to stop the data generation at T0 during the morning, but there was a CERN wide powercut (see http://cern.ch/ssb), so this was the end of the generation. We just wait and see all the subscriptions to be processed and replication to be completed.; A snapshot will be taken at noon tomorrow - subscriptions and monitoring by Alexei will be stopped - and then all the ccrc08_run2 data will be deleted.; dashb monitors are still down - dashb-prod shows the graphs only up to 04:50, dashb-t0 still not accessible.
