Re: I can't login to blockchain.info due to "EMAIL CODE (2fa)"

No change.  I've checked it two or three times a day since 11 July and no change in behavior.

Support keeps suggesting reset 2FA which takes weeks minimum and I suppose I'll never be able to use this email address for 2FA again.  But email works and AFAICT blockchain doesn't.

Appears to be working today, kinda.  2FA seems to be deactivated, at least for my account.

Hi guys,
What is the best thing to do at this moment to login to my blockchain wallet?

Last 2-3 hours I have been trying to login, but due to the "Email Code" I am unable to login.

It will be appreciated if someone helps me out.

B. regards

After a day, so how is it now?

I have had the same problem starting 11 July.  I was getting the emails delivered appropriately on 10 July.

I have checked spam folder on gmail, no emails from blockchain there.  Interestingly enough if I go to an incognito tab and try to login I will get the "authorize log-in attempt" email.  So it seems like it's not as if GMail is rejecting all mails from blockchain.info.

I opened a support ticket but the initial response suggested checking spam folder and resetting 2FA.

Ok, thanks.  So is it up to each security what they want to do in the face of this event, then? 

They need to each decide independently which exchange they're moving to, or does btct get reincarnated somewhere?

I'm not condoning the "attacker" if indeed that is what happened. You need to do some reading of Coinhunter/Realsolid going back to August 2011. Come back and let's discuss.

Unfortunately, mr.Mtrlt has a tendency to look really shady and scammy for no reason at all.

If the rumour mill is correct and the mrlt realsolid coinhunter senario is true ...

MicroCash 500BTC & nothing 
GPU miner ~100btc & nothing that works

These are the recent "DONATIONS" operations he has pulled in the last 3 months  Shocked

Please, put your pitchforks away...

The miner looks totally legit.  If mrtlt came up with a bogus miner, then he spent a lot of time making it look like it works.

I saw what looked like a legit block solution that didn't fail the primality or difficulty tests, rather some early packet size filter that caused the submission to get rejected.  Sounds like a bug somewhere, bound to get addressed.

Has anyone actually mined some coins with the gpu miner? I read that paul's coins were a false positive and that he didn't mine them with gpu's but with vps...



Well, I'm scratching my head on this one.  I had two instances of reaper running overnight, both connecting to a single primecoind instance.  Both of the reapers now show a nonzero count for the "10-chains per hour" stat.  Based on my understanding of the code, this stat doesn't get filled in until/unless there's a single entry.  Yet there's no record of a "immature" or "generate" (or even "orphan") entry in the primecoind's "listtransactions" output.

I'm left wondering if maybe there's something wrong with how reaper returns work when it finds a block at difficulty?  Or my primecoind is misconfigured somehow?

Ok, more breadcrumbs:

Code:
getblocks -1 to 0000000000000000000000000000000000000000000000000000000000000000 limit 500

Maybe I'll find some time to move over to testnet and capture the submission over the wire from reaper to see what might've been wrong.

Now, i'm running in to config issues. It's probably something simple, but I'm getting 'Couldn't connect to server.' errors.
I have primecoind running with server=1, and I have a rpcuser and pass in my ~/.primecoin/primecoin.conf file.
What do I need to do to get running now?

My primecoin.conf (in the reaper dir) is:
Code:
host 127.0.0.1
port 9914
user primecoinrpc
pass

protocol primecoin

worksize 512
aggression 21
threads_per_gpu 1
cpu_mining_threads 4
vectors 2
primecoin_address

use_gpu true
debug 1
device 0

What am I missing here?


You sure that port number's right?  Check it.

Code:
netstat -tpln
on *nix,
Code:
netstat -p tcp -an
on windows.  Look for or grep for the port number you're using (bound to either 127.0.0.1 or 0.0.0.0).

I didn't have jansson installed when I built reaperprime, so I downloaded the newest one (v2.4).  But when I used that one, reaperprime ran into a compilation error.  Maybe the API changed?

Wha..?!  No way!  NVIDIA has a huge advantage over AMD in many aspects.  Just look at how well their software works compared w/AMD's.  You still need an X server running to do computation with AMD GPUs and that totally blows.

NVIDIA made a poor (IMO) strategic decision by abandoning OCL but you still have to give them the credit for creating it!  I think they were afraid to abandon their early adopter CUDA customers and decided they didn't have the throughput to support both.

I think eventually they'll reverse their position on OCL.  But to a lot of folks doing GPGPU they don't care about OCL and they're using CUDA and loving it.  So it's not fair to say "NVIDIA is poor at doing anything GPGPU" IMO.

OpenCL Trademarks belong to Apple Corp. I dont think Nvidia made OpenCL.

They might be good at GPGPU, but only on the GPU's that specialize in it. ie. Their tesla series. The consumer GPU's they make aren't as good.. but they are also the vast majority.

Idk.

All I know is that the GPGPU software I've seen out there runs tons faster on ATI cards than it does on NVIDIA cards.

Yeah, Apple owns the trademarks because they're the ones who brought everyone to the table.  Apple loved CUDA but isn't dumb enough to sole-source any of their parts.  So they told NVIDIA and ATI that they should all play nice and standardize CUDA.  OpenCL was the result.  It's only barely different from OpenCL.  The biggest differences are primarily in making CUDA fit a programming model similar to the shaders already used in OpenGL.  NVIDIA wanted to win a contract with Apple and they had a huge headstart on the competition.  AMD's Brook and CAL/IL was mostly a flop, so they would happily jump onboard with a Khronos standard.

If you look just at hashing (and now prime number computation), you're missing a much bigger part of the GPGPU marketplace.  Most of the GPGPU customers (in terms of units purchased) are running floating point computations of enormous matrices and using the interpolation hardware.  They're used in scientific applications, Oil&Gas, Medical stuff, etc.  In those applications, NVIDIA does very well, often better than AMD.

Any word on getting this to work on NVIDIA cards? From what I understand it's because the nvidia cards don't support opencl 1.2 (yet?). Any potential workarounds on windows or linux?

I doubt it's a priority.  With NVIDIA's poor integer performance it seems like it's not even worth it.  Maybe it would be if the GPU miner could hit ~20x performance over typical CPUs, but as it stands it's not really there yet.

But yeah there's definitely a way to eliminate the dependency on OCL 1.2.  You just need to find someone motivated enough to do it.

I've made the primality tester 4-5x faster, but I haven't managed to fix the "fractional assert" problem. Should I just release the faster version (many people won't be able to use it) or try to fix the bug first (will take time)?
If this is of any help, looking at the console as all the data flies by, my setup (i7 chip, win8, 64bit) reels out all the data, starting with 0 fermats/sec and 786 gandalfs/s, then as time passes, the gandalfs/s progressively drops and if the app doesnt crash earlier each time the console reports the gandalfs/s it shows a smaller and smaller number, reducing to 60 gandalfs/s then it usually gives up and passes onto windows error reporting. It always only shows 0 fermats/s - ? what is this meant to be?

I had this same issue with the gandalfs dropping and I managed to keep it at a regular average number by playing around with the "worksize" parameter in the primecoin.conf , got the best result with 64

I can confirm worksize of 64 was optimal for me too.

The TOTAL counts aren't comparable between use_gpu_fermat_test true/false, should look at 2-chains. I'll remove the TOTAL count in the next version.
Good to know, thanks! Looking at 2/3 chains then the gpu_fermat_test is faster by ~ 1.4x (I do have a weak CPU in there).  Is the candidate difference a red herring (1/9 as many) or just the way it is reported?
I'm just not seeing stats anything like this.

With the fermat test done on the GPU I get...
0 fermats/s, 6.73269 gandalfs/s.
70.2502k TOTAL     1.79828k 2-chains     39.093 3-chains     39.093 4-chains

With the fermat done on the CPU I get ...
60338.8 fermats/s, 3523.21 gandalfs/s.
350.383M TOTAL     1.01852M 2-chains     64.7127k 3-chains     3.58685k 4-chains     298.904 5-chains

Ignoring the total, the fermat test on the GPU gives 1000x fewer 2-chains,  and 100x fewer 4-chains.  This is with 2 x 7950, a AMD FX(tm)-4130 Quad-Core Processor, and ubunutu 13.

Am I missing something somewhere?

I got similar results enabling/disabling the fermat test on the GPU.

Can this be used to mine in ypool?

I don't think so.  Ypool uses XPT exclusively, IIRC.  I think primecoin-reaper uses getwork, so someone would need to port XPT to it.

I can't explain the failure you're seeing, but trust me when I say your Intel HD graphics device will be a total dog on primecoin.  When primecoin-reaper hits its stride it might be worth your time, but not yet.

Does Intel's OCL kit come with a "clInfo" executable?  That might list the devices and you could see if there's actually one presented that matches the qualities being searched for.

I should have been more specific: I think there's a problem if you compile it yourself on 64-bit Linux. The supplied Windows binary is 32-bit.

Ubuntu 12.04 + x86_64, AMD GPUs -- works for me.  No blocks yet, but it looks busy and the numbers are sane.

Any info on how to fix the appcrash? seems many of us here are experiencing that.

I had a crash until I patched libblkmaker to support primecoin.  Have you already done that?
