Are people seeing this on Linux also?

Mine's Linux.

but my 2nd and current run is 6 hrs and no msg yet.. so it looks to be hard to reproduce ..

ok, 8hrs in and I got it again.

This time around I am using the SSE version on my i7.

Interestingly, sse ver has lower 2ch/s but higher 4ch/s.. not conclusive since only 13mins

Ahh, thanks for the very helpful debug output.

I've updated the miner to b12 and committed into the repository.

b12 fixes a known bug with not regenerating the nonce time frequently enough for ypool.  The miner now resets its time nonce every minute instead of every block.

This slows down the miner a bit.  Sorry - but it should compensate by not having invalid shares as often.  You might find that reducing -s slightly helps.

But there may still be lingering buts causing this "not a valid prime" error.  I'm going to keep digging, and will work on getting some of that speed back in b13.

How are you all using the avx2 version?

I downloaded it and it is just a file and not a program like the sse4 version.

If it needs compiled does anyone have a compiled version for windows?

If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks Wink

I think the avx2 version is Linux only.

It's a linux executable program.

The names of Windows programs always end in .exe
Linux programs usually do not have a file type ending.

The ypool chat room was full of people noticing that b12 slowed down too much, so I've pushed b13 as a compromise between safety and speed.  But it also includes an important bug fix (which should be masked by the other one, but fixing bugs is good).

 http://www.cs.cmu.edu/~dga/crypto/ric/
and in github:
 https://github.com/dave-andersen/fastrie/

Also, there's now a ChangeLog that covers all of this stuff:  https://github.com/dave-andersen/fastrie/blob/master/ChangeLog

It may be slightly slower than b11 when a block takes a long time, but it's not too far off.  It might even be a little faster for fast blocks, but overall, it's probably 5% slower than b11, but it won't get into the "invalid prime" problem.

There were two bugs in b11:
  - If it went too long before a new block was found, it could overflow the 256 bit riecoin nonce field -- I changed some constants and didn't re-do the math on them.  This is now computed based upon those constants, so the bug shouldn't reappear.

  - It could run for too long without updating its block time field, which would cause ypool to reject it even if it contained a valid share or block.  I've mostly kinda sorta fixed this, but the current version reflects a compromise between safety (updating the time field frequently) and efficiency (running as long as possible after computing a target).  This one's a "let's run it and see how it does" kind of thing.

For people who like to read the source of these things, the internals have gotten a little cleaner, which hopefully makes the logic a bit more clear.  In particular, I think the offset computation should be easier to read and understand now, for those seeking to understand what makes these miners tick.

The most important fix is that it addresses the lack of a changelog to answer questions like this. Smiley

https://github.com/dave-andersen/fastrie/blob/master/ChangeLog

(I suppose the changelog should include that b13 includes a changelog. :-)

MY PC uses like 5.1GB memory with this miner, is this normal?

Seems to be normal on machine with several cores.
Here is the mem usage on one of my systems:
Code:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                                                                                                                             
 3104 root      20   0 31.5g  28g 1052 S 4810.3 74.4  28803:26 xptminer-sse4-b                                                                                                                   

Is yours an 8 core machine?

Well I know on my Win 7 I have a 8 core 8320, it uses 5.1 gb.

On my 4p 64 core ubunto it would crash and had to limit the mem to 4gb per processor, it REALLY wants more and more.  I am not sure if giving it more would benifit the miner?  So in general I have allocated a total of 15.7 GB to the 4p opposed to the 21gb it sorta wants.

For some reason, when starting this up on my server it hangs after the "Launching miner..." and just exits. I'm on CentOS 6.4 and had to compile against custom built gmp as the one CentOS had was outdated. No errors or anything though. I also tried your prebuilt binaries, same thing.

Memory usage is related to the sieve size (-s), and by the amount of cores your CPU has, or threads you use. Default sieve size is -s 500000000. If you find it is using too much memory, or freezes or crashes upon running the program, just decrease the sieve amount to a lower size. If you have more memory you might want to increase it, it may help performance. For reference i'm using -s 675000000 for the 8 core i7, which uses about 6.5 GB of RAM. On other systems with 4 core i5's i can use -s 900000000 which uses about 6 GB.
