For me it seems that the reject rate it going up for miners which do not have that my cores.

I am currently using 2x 32 core AWS spot instances for testing throughput, an 8 core i7
and a couple of 3 core virtual machines.

The reject rate for the 32 core monsters is below 1%
Reject rate for the 8 core is below 2%

And the reject rate for the 3 core things is at about 15% !!!
(I have 11 of those, and ALL of them have high reject rates)

I think I can see some pattern in this...

Unfortunately I don't know enough of the underlying work distribution software,
but maybe I am not the only one experiencing this situation and it would be
great if there might be some fine-tuning possible?

Who has the same experience?

I'm having the same observation mate. More cores - less rejections.

if this is true it can be a very helpful information actually

@btc2084:
as you see the rejects come in blockwise (ends on "work received"), there's a bug somewhere (in the miner i ---guess---)
this is a known issues, there's a dirty workaround in the latest github (not helpful for windows user i know)

@recci:
protoshares is 1 year ahead of it's schedule... just saying  :)

I would be more interested in the number of rejections vs the percentage. Presumably, a larger number of cores can process a larger number of shares, so if it's a fixed amount of rejects no matter the core number, it would appear to be a smaller percentage with more cores.

Not sure what you mean? Also It turns out I was mining more than I realized. I missed a couple of payouts, turns out I have 0.6 of a PTS  :-\

That means we mined that block, but someone else mined a block as a child to the same parent as ours close to the same time, and the network accepted the other child and thus rejected ours.  Since our block didn't make it into the final chain, we get nothing for it.

I have 494 rejects of 3553 valid shares. Is that number of rejects normal?

keep in mind that it's mining to a location in new jersey

can you two post the # of threads you're using on your servers??

@orphans:
the orphan streak was caused by the stuck protoshares backend like i said before
but the last one is just bad luck, just like Troglodactyl (thank you) said, it's not possible to prevent this completely
on the other hand, if a pool is big enough it could intentionally try to 'orphan' blocks by other pools/users <-- just saying, in theory

or it could be indicative of protoshares client not connected to enough and/or the right peers, or another situation would be a lack of bandwidth and connected to too many peers.  in that case, it'd try to send to them all at once and they'd all get it slow.

I received block 28005 and 28039 from a peer in Germany, despite the pool being in New Jersey (and having over 100 connections in protoshare client).  I imagine it doesn't have very good connectivity (or not enough peers), or maybe it funnels everything through that Hetzner machine (which wouldnt be so hot with the +120-140ms).

re: the 3rd one, I don't think it's done intentionally, but, yeah, there's a... uh... slow quark pool that controls about 80-85% of the hashrate and orphans some godawful number of blocks

germany is 7 cores, dallas is 4 cores, houston is 4 cores, the rest are 8 cores

i have some machines running 2 cores here on my home connection that are ~97% valid

ed: in my protoshares log, there's only 1 orphan in the last 6 hour or so and no reorganizations

Registered just to report this same issue, large percentage of rejected shares in the last day or two:

Home systems (crashing/rebooting often so the counts are reset often):
4 cores - VL: 255 - RJ: 101
4 cores - VL: 216 - RJ: 48

Hosted server:
8 cores - VL: 29313 - RJ: 3383

33 rejects, 5088 valids on a Buffalo, NY server
29 rejects, 2433 valids on a Las Vegas, NV server
24 rejects, 1773 valids on a Las Vegas, NV server
0 rejects, 158 valids on a Scranton, PA server
2 rejects, 144 valids on a Dallas, TX server
1 reject, 74 valids on a Houston, TX server
42 rejects, 1745 valids on a Germany server

Now it's

92 rejects, 10377 valids on Buffalo, NY server (8 cores)
57 rejects, 5090 valids on Las Vegas, NV server (8 cores)
60 rejects, 4352 valids on Las Vegas, NV server (8 cores)
7 rejects, 1070 valids on Scranton, PA server (*8 cores) --  ed: it just seems like 4 cores.  gimp Xeon =(
10 rejects, 1128 valids on Dallas, TX server (4 cores)
5 rejects, 448 valids on Houston, TX server (varies)
69 rejects, 4053 valids on Germany server, (7 cores)
18 rejects, 1494 valids on Lenoir, NC server (8 cores)

these are all using the latest git pull, diff versions of ubuntu,  about half on 12.04 and the other half on 13.10

they're also all using the 1024mb memory option

oh, jfyi, that Dallas server is from burst.net...  any new customer can get a server for a month for $1 from them, w/ no strings attached (besides having to remember to cancel it in time)
