Dear Markus,
This is the answer from PIC+IFAE in Barcelona.
0) Do you support PROOF for experiments or have concrete plans to do so? YES
1) I am at a T0, T1, T2, T3: T1 (PIC) +T2 (IFAE) + T3 in the same computing room
2) Do you run a dedicated cluster of or does PROOF run on top of your
production facility?
We run a dedicated cluster facility of 96 cores.
3) Do you provide dedicated storage? Yes, but data can be read locally
from T2 and T1 as well.
4) Do you use PROOF with your WLCG-SE? We have dcache and users can
access data from our WLCG-SE endpoints. Used protocols are xrootd,
dcap and gridftp. The allocated space for T3 usage is 50 TB apart from
the possibility of reading data from T1 and T2.
Hope it helps. Andreu
