Hi Rob,

I agree: It would be great to have weekly meeting to know the developments in "atlasconnect" and if there is any other urgent needs to address to any issues.

1. Just for info: One of the main concern for me was our Tier-3 bandwidth for the data transfer during the condor jobs. At this moment its 1GB but scheduled to increase to 10GB in summer probably. But I wanted to check by submitting the condor jobs in our cluster which reads the input file from Tier-2 (using continuous bandwidth) and I used FAX system. I am happy to see that its working at this moment. Although the jobs are not very high in number but it works according the job slots available on our CSUFresno ATLAS cluster. 

Attaching the network plot during of the job. 

2. If you remember, we had discussion before about the environment difference between clusters. I observed if i submit the job through "atlasconnect" the default os is slc6(may be my area) and CSUFresno Atlas cluster, we have 5 nodes on slc5 and 2 on slc6.  This was leading to my jobs failed in some nodes.But now after I get to know the real reason, I modified my submission script to check first the os and setup Athena/Root accordingly. 

The above tasks were on priority for me (as presented in Arizona workshop) since I can use "atlasconnect" in doing the analysis using ROOT/athena now and I see FresnoState cluster working great at this moment with whatever resources we have.

I will continuously doing some more rigorously testing involving analysis and data...

Thanks & Regards

Harinder

Hi Yongsheng,

Yes indeed.  This week is tough for us as we’re still working on the network upgrade where the atlas-connect-l services live.   Lets maybe plan on one next week.  I’ll send around a doodle poll for the specific time.

Cheers,

- Rob

Hi Rob and others,

Happy New Year!

Harinder is doing tests as discussed in the Arizona workshop. Perhaps we could resume our weekly ATLAS Connect meeting soon. As new semester is starting with different working and teaching schedule, perhaps it is a good idea to pool the mailing list again about meeting schedule. Thanks.

Best,

Yongsheng
