Hi all.
We have some jobs running at CGG-LCG2 from the VO biomed. Each one must
download about 300 MBytes of data from SEs then runs during few minutes
(between 5 and 10 minutes). With several simultanious downloads we
obtain a very low data transfer rate and the CPU does'nt do any thing
for a long time (more than 20 hours). I noticed today on Worker Nodes
that the process lcg-cp is running but the size of downloaded files is
not growing at all.
Does this mean that the lcg-cp process is blocked ?
Is there a time out for lcg-cp after what it stops downloading data from
the grid ?
Do you think it is a good thing to allocate the CPU for a job even if
the data will be in the node 20 hours later ?
Thanks in advance for your help
Regards
