RE: SETI has now started

SETI has now started generating work again, so I expect the Einstein demand will decrease over the course of the weekend as users switch back - that will allow our WUGs to have a better go at maintaining a supply.

My machines still suffer lack of BRP4 CUDA tasks. It is hard to receive CUDA tasks. I have to force multiple BOINC requests to receive tasks at least for a day. SETI doesn't help to resolve this issue. So, we are hungry to crunch some new numbers.

SETI's work generation phase lasted for less than 36 hours (this time) - they ran out of raw data on Friday evening (UTC), and have been unable to supply work since then. The added pressure on our servers continues.

Seti is producing new work.

It is rather strange. There are many other CUDA projects, but it seems SETI users prefer to run E@H as a reserve project whereas other projects give more points per hour then yet they do not suffer of SETI machines.

Something happend. Queue

Something happend. Queue begins to grow.
I wonder why BRP4 work generators ## 0,7,8,9 and 18 are disabled all the time? Are they for some special tasks?

I figure some GPUs got work from SETI and thus don't ask work from E@H.

These are just configuration slots.

WUG #1-6 run on a second machine that doesn't have enough resources (disk space, cores) to run more than these 6 instances.

WUGs #10-19 run on the original machine (einstein-wug). Enabling more than the currently running 9 instances makes no sense there. Every additional instance running on that machine slows down the runtime per beam of all WUGs by roughly an hour. I.e. although the system load would be higher, the number of WUs produced per hour would stay the same. In addition, mindlessly overloading this system would be bad, since the FGRP daemons and the other BRP daemons (validator, assimilator etc.) are running on this machine, too.

It gets worse. BTW, it is the end of "the next week". Any news about configuration changes?

This is not about changing configuration. It means designing and implementing a new scheme of workunit generation. Oliver and Benjamin are working on it.

Additionally last night a network cable broke that connected the 'relief WUG machine'. All BRP4 workunit generation was stopped for ~10h.

But why just not to install

But why just not to install an additional relief machine and get rid of the problem instead of implementing a new mechanism in a hurry? New scheme can be then implemented whith the start of the next run. Or is it a heat wave coming from the additional rig and it do not allow to work? ;)

Have you donated enough to

Have you donated enough to pay for the additional relief machine? They do not have an unlimited budget, even if there's no heat problem.

Or would you prefer to donate only enough to buy a new cable for connecting to the relief machine they already have?
