African Rainfall Project (ARP) resumed and Open Pandemics (OPN1) downloads are slower than a snail again. With the lack of progress, I am beginning to think Krembil may pull the plug on WCG.

2023-01-25 Update (ARP & OPN1 workunits)

ARP & OPN1 workunits

On Monday afternoon, many volunteers reported receiving new ARP1 and OPN1 workunits. These workunits are not from a new batch; these are older WUs that were never sent out due to an overloaded server causing problems in our workunit-distribution process. ARP1 and OPN1/OPNG teams remain on temporary pause, preparing new workunits.

In addition, this infusion of about 2 million WUs helped us to confirm that the networking/download issues we have in the data center persist under a normal load. Improvements made by the SHARCNET team did reduce network congestion. However, based on these results, they are now implementing further modifications to the network, which should resolve these issues for the future. We will keep you updated with further details about the upcoming maintenance, once we receive more information from the SHARCNET team.

Thank you for sending reports of HTTP errors that were experienced by volunteers processing the recent ARP1/OPN1 workunits, which helped us diagnose these errors. The effect is especially strong after an outage, because of the pent-up demand by all the connected BOINC clients. The backlog of workunits released for distribution over the last few days produced the same effect. We continue working together with the SHARCNET team on improving our network. In parallel, we are finalizing the SSD storage upgrade we mentioned in December, and this will also help in improving WCG backend performance.

If you have any comments or questions, please leave them in this thread for us to answer. Thank you for your support, patience and understanding.
