Regarding to latest problems with tasks submissions to your computers we plan to make some maintenance work on our server and results analyse machine at the end of this week or start of next one.
The server will be stopped for about 6 hours but I will publish info when this happens before we start.

Maybe you could look into the time estimates too. I know this has been discussed at length, but the BHspin v2 have an estimated running time of 6 minutes, when in fact they take over 2 hours on my machine. It increases the number of downloads beyond a desired amount, and makes it difficult to run other projects along with Universe, though I now dedicate an entire machine to it, which makes it less of a problem.

I agree about the timings. When downloaded they're saying 00:06:02 for estimated completion time, but they're taking closer to 03:50:00 to complete on my rig, which makes the actual time 38x longer than the estimate. As I run multiple projects, it means the manager downloads a lot more than it's supposed to, and winds up taking up a lot more than it's share of resources in order to be completed on time.

Same for me as well. I looked at one of my machines and had a ton of 7 minute BHspin2 tasks. I will let them finish , but like Jim1348 mentioned it throws off the project priority.

I am not sure if the fix was already in place, but I am seeing that all my laptops are getting workunits. The new BHspin tasks are also coming in with the correct time. Thank you krzyszp for your hard work :)

Here it isn't so, for all tasks on Linux arm and arm64 machines, the manager means the task takes ~100 hours. Really is ~ 10 hours.

I am now seeing one hour estimates for BHspin2 tasks on my two Ubuntu 16.04 machines (i7-4770 and i7-4790). That is not perfect, but it is much better than the six minutes I was getting before. I don't think it will cause me any significant problems. Thanks.

Not yet, as one of the required person are on holiday at the moment, but I have significantly increase expected FLOPS number in new WU's.

Any progress on the server updates ?
When can we expect new UV tasks ?

Thanks,

Tom

I have to release some server resources as we preparing to:
1. Installing new SSD drives.
2. Preparing server to new GPU app.
3. Make some decisions about new incomming hardware (planned in next few months).

I know, that it is not expected information, but this is live server and live project and I have to be carefully with all changes... :(

Thanks for answering the first question, but what about the second question ?
When can we expect new UV tasks ?

Thanks,

Tom

Curently science team analyse finished UV tasks. When they finish we probably get updated application with new WU's. How long it takes? I really don't know, everything is based on currently received results...
