I've been able to get enough lucky hits to stay busy, but have to look often to see what's up.

There hasn't been any AP splitting for days.
Server Status page looks like it's time to mount some new files, so AP splitting should resume soon. That should help with the work shortage.

It's a nice change of pace for them at least being able to send what they can send.

The Cricket is doing a rather steady 200Mb/sec.....so work is flowing.

Much better than with the old 100Mb cap.

I shall join you in that whine...LOL.

I only have 9 rigs against your many.
I have Killawatts on a few of them, and they are showing little activity.

The Einstein project should be happy in my case at least. I had to go add it as a secondary project again because I just can not keep enough work even though all my machines are CPU only. Not what I would like to be doing, but it is better than letting the NULL task get all those CPU cycles.

Actually all kidding aside on this, if you can't even get CPU work units (and I am having the same problem here) where are all the work units going. The outbound pipe is running at twice the capacity of before yet many of us are starved for work. Anyone care to speculate or am I missing something obvious here?

there are other servers, non seti, connected to that switch so the outbound traffic is meaningless now...

The splitters and scheduler appear to be very "relaxed" just now. They deliver nothing for a few cycles, then dump a fairly large pile.

When Who or What makes the decision to assign a task to

1. CPU
2. ATI
3. Nvidia

Roundrobin or based on request or random or persnickity algorythm?

Depends what people mean by inbound & outbound. Is it from our perspective, or the routers?

Same as the last router- outbound on the Cricket graphs is inbound to the project (Scheduler requests, return of completed WUs). Inbound on the Cricket graphs is outbound from the project (our downloads).

Assuming the requesting cruncher has the capability, and the required apps installed:
All task types can be processed by any CPU.
Nvidia are very bad at processing VLARs so they aren't assigned (or shouldn't be assigned) to Nvidia processors.
AMD/ATI in principal have no limits (provided they are above a certain level?).
However at one time there was (and maybe still is) a blanket embargo on VLARs being sent to any GPU.

Assuming the task is able to be processed by any of the available processors on the the requesting cruncher it is then assigned to the most powerful processor on that cruncher. This assignment is done after a cruncher has made a request for new work, and on a task by task basis.

My point was to counter rottenmutt's statement that there are non-seti servers on that router - Joe says not so.

As to the original question, what has changed is the bandwidth bottleneck is not there anymore, so ALL Scheduler Requests get through, instead of failing due to high traffic or the connection being timed-out before the server reply is sent. Anybody getting "ghost" tasks?

As I understand it, the splitters are running at about the same rate as they were before the move, so there are more successful scheduler contacts competing for the same number of available tasks in the feeder (IIRC, 200 at a time, refilled every 5-6 seconds). So more sucessful contacts get the "no tasks available" message. And the current "shorty storm" just makes it worse, since most crunchers process shorties in about 1/5 the time of a mid-range or VLAR task.

Your BOINC Manager makes the decision and it will fill your fastest resources first before your slowest ones.

Uploads and reporting are working fine, I just can't get any downloads, cpu or gpu...

It generally takes between 2-10 requests to get work.
The splitters are no longer producing enough work to maintain a ready-to-send buffer.
The fact is most of the time they're not producing enough to even keep the feeder fed.
