Oh god, what have I done?

Nice   But why?

Gigawatt- can you go into detail about how linode handled things?  Did they just boot you without warning /communication?  Curious as I still have 8 cores running with them but have not had any disruption...yet.  Have immature blocks there that I should probably address before I lose them

Edit:  also did you consider myhosting ?  Can be cheaper than linode

EC2 is pretty pricy compared to other VPS services like Linode, but at least they don't boot you for loading up their CPUs.
Hell, they actually encourage it.

Yeah it is pricey, even with spot pricing, but yeah you do get what you pay for. Which is more than I can say for most. I have no regrets with my mining operation there 

Recent price reductions in some EC2? I got a e-mail..

Hi guys,

I've got a problem with hp9 (not sure if it occured with earlier version). I use primecoind on Windows Server 2008 launched as a service (indirectly) with an external program which does this. I use few VPS for mining purpose and it's sometimes on every of them that blocks stop downloading. When I type primecoind getmininginfo I can see the same number of blocks every time I check it and it's stuck. When it doesn't download blocks, the mining cannot run properly. Anyone encountered this and know how to solve?

How many connections? Sometimes it just hangs, especially on first run. Will happen with all daemons, though.
If you lose connections (can use "getpeerinfo" to see). If you have multiple vps's, you can add them as nodes to download from. i.e. "primecoind addnode 10.244.27.72 add"

I have 8 connections all the time. I don't lose connections. I added about 40 nodes in primecoin.conf that I've found on the Internet. Also I included my other VPS. I have switched firewall off and P2P port 9911 is open and accessible from the Internet. Tail from debug.log:

It's stuck on block no 117308 and there are at least 10 newer blocks further. Anyone got some idea?

[Trillium]

Hi guys,

I've got a problem with hp9 (not sure if it occured with earlier version). I use primecoind on Windows Server 2008 launched as a service (indirectly) with an external program which does this. I use few VPS for mining purpose and it's sometimes on every of them that blocks stop downloading. When I type primecoind getmininginfo I can see the same number of blocks every time I check it and it's stuck. When it doesn't download blocks, the mining cannot run properly. Anyone encountered this and know how to solve?

Check the computers BIOS and OS clocks are correct. Some OS refer to the BIOS and others refer to other time sources, it depends. It must be accurate for most crypto clients to work correctly.

Also, downloading and indexing the blockchain is intensive on CPU, memory, and especially disk IO. If there is a hardware instability problem or a driver issue with the chipset, you might find it 'just stops working', crashes, or BSODs. I realize if you are running on VPS this may be difficult to test.

[gigawatt]

Oh god, what have I done?

Nice   But why?

Gigawatt- can you go into detail about how linode handled things?  Did they just boot you without warning /communication?  Curious as I still have 8 cores running with them but have not had any disruption...yet.  Have immature blocks there that I should probably address before I lose them

Edit:  also did you consider myhosting ?  Can be cheaper than linode

There was a "resource abuse ticket" opened for using 800% CPU on a handful of VPS.  They shutdown the servers for safety and sent a notice saying that I needed to not use so much CPU because 1) it's against their Acceptable Usage Policy and 2) it was affecting other nodes on the same hardware.  I could either cut back on CPU usage or (they phrased it much nicer) close up shop for a refund.

I deleted the servers which added the remaining time as account credit, then had the credit re-applied back to my bank account by sending them a note.

And that was the end of that.


edit: myhosting looks good, but their AUP will eventually catch up to you: see section 11.t


edit2:  This is what they said.

It has come to our attention that all of your Linodes are using close to 800% CPU usage. This is negatively impacting the hosts on which your Linodes reside and subsequently your neighboring Linodes. We must ask that you stop CPU intensive processes on your Linodes, and inform us once you've done so.

After asking about a refund:

You will receive a credit for any unused time on your account, and once you have that credit, we can refund that back to your card minus a $5 processing fee. Please let us know when you have said credit and we can process that for you.

So yeah, they gave me the boot, but they were quite nice about it.

I can never understand companies that give you a product, and then penalise you if you use it to its full capacity.

if you dont want someone using 8 CPUs at 100% then dont bloody well give them 8 cpus in the first place!!!

Well, if you paid for a sports car, you kind of expect to be able to treat it like one.
Otherwise, you'd rent a station wagon.

Not really the same thing.
If you rent a car it usually stipulates that you have to use it within the bounds of the law and NOT take it to a superspeedway and drive 150+mph.

But in this case you are being charged for 8 cpus, but then get kicked off the service if you use the 8 CPUs.
On Amazon AWS you buy an 8 CPU instance, you get to use all 8 at 100%
Same on Windows Azure and Google Cloud.

So what is your 1 Chain price in USD? For example, if you pay 30 USD per month for a server that is making 5 Chains/day, it is 1 USD for 5 Chains, which means 0.20 USD per 1 Chain. So what is your best?

You mean price per block?  On Amazon's AWS with a cc2.8xlarge, it comes out to ~$6 / block.  That assumes you have average luck.

actually, no, I really ment per Chain as in the Chains/day statistics

[Entz]

actually, no, I really ment per Chain as in the Chains/day statistics

Spot priced cc2.8xlarge is ~6$ / day / instance (per block is a bit generous) and that gives you ~2.8 chains per day. So ~$2.15 per chain per day.

(note that this is at default HP9 settings, sure this can be increased)

$2 sounds extremely expensive, but interesting

[Entz]

I would tend to agree, but I have yet to see anyone offering a 16C/32T near-dedicated machine that encourages 100% cpu usage for less..

Would be nice though as EC2 is borderline now (hasen't been good for a while, but now even more)

Even a decently priced dedicated 8C would be nice.

[gigawatt]

One of the small DigitalOcean droplets gets 0.16 chains/day and costs $5/mo.
$5/mo = $0.167 / day
$0.167 / 0.16 = $1.05 / (chain/day)

Linode gets about 0.95 chains/day and costs $20/mo.
$20/mo = $0.667 / day
$0.667 / 0.95 = $0.70 / (chain/day)

FortaTrust *shiver* gets about 0.75 chains/day and costs $15/mo.
$15/mo = $0.50 / day
$0.50 / 0.75 = $0.667 / (chain/day)

Cheaper is never the issue, cheaper while not getting your nodes kicked off due to high usage is    Oversold vps crap...

The only real option I have seen is server4you, 8C for ~70/month. Which is a good price (looks like 6134s which should get a block every 2 days)

What's the ballpark "chains/day" stat on that?


Nevermind, I wouldn't even consider them.  This is in the footer of the page:

* Root Server: EcoServer & ProServer: Prices plus $149 one-time setup fee. BizServer: Prices plus $199 one-time setup fee.
No setup fee? No problem! Just add $15/month and the setup fee is waived.

Have no idea, that is a what blackboy is running (and cheapest dedicated I have seen). Maybe he can post his current numbers

Yeah I noticed that pricing as well after. and based on the specs they are running desktop Opterons (AM3?) vs G34 so can't even estimate based on my 12C Opterons. You can do the 88$ / mo with no setup. If they did somehow make a block every 2 days, 88$ per month would likely still be more profitable than EC2 over the next few weeks (or the price per XPM needs to go up a lot more)...
