Alright, so I got Arktika to work. Part of the problem was that I had 6GB of chunks allocated to nodes with 8GB of RAM. Those nodes failed with Java Heap overflow, so those nodes would refuse connection. I reallocated the chunks, only 4GB to 8GB nodes and 8GB to 16GB nodes. I started the worker and nodes and in the mean time before all of the nodes were up, the `WARNING: Error: io.grpc.StatusRuntimeException: UNAVAILABLE: io exceptionio.grpc.StatusRuntimeException: UNAVAILABLE: io exception` persisted. When all of the nodes were up, there were no more errors and the arktika miner is reading out hashrates :slightly_smiling_face:

congratulations :slightly_smiling_face:

What is your hashrate with this setup?

So my memory server, the worker was at 800K and it dropped to 650K or so and the other nodes are from 50 to 70K with 8-16GB RAM. These are HPProliant DL380 G6 servers. It may not be the most economical; I'll have to watch once this gets on the exchange, but I had these idle after mining a different CPU coin. That coin isn't profitable to mine. I like this coin and am excited about it so I wanted to get something going

Really grateful for this helpful community: Thanks @mjay @Fireduck @Clueless @Rotonen @SidGrip

You´re welcome! What is your bottleneck currently, network?

800k is at least 77MB/s, close to the limit of Gbit

yeah, I would agree it's the network

what cpu´s are in your servers?

dual Xeon X5650

I had a similar setup running with DL180 G7 servers, slightly faster CPUs (X5670) which maxed out at 900k

They benchmarked as the best value for the dollar

I switched over to DL580 G7 servers after this

I like the idea of running a DL580G7 with that E7. I saw above you posted the link for that server on ebay and I contacted him to see if he'll deliver to the US.

are there no such servers in the us?

You could also check for BL680 (same but as blade, they are even cheaper)

I also saw a DL580G7 with over 400 GB RAM that was around 1000USD. That was worthwhile for the RAM but the processor wasn't an E7

Also the Dell RX600

hmm. I haven't seen any E7s

okay. I'll shop around, thanks.

Or Ibm X3850

same hardware different brand

ibm is really loud however, same for the blade center

place them on wheels and they move just from the fans

lol

checksum mismatch

how to solve it?

what checksum?

@mjay don’t discard oracle and fujitsu sparc for snowblossom if LOUD is an option

my honda civic beats them all

nvm i solved it

it was just faulty snowblossom release

care to clarify?

maybe download didnt finish properly

or something

when i unzip it

but its weird though
