1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Bullion (CBX) 'the Digital Precious Metal' | 2019 Roadmap published on: June 26, 2021, 10:42:18 AM
Thanks for the update, if you're out of pocket at all for the VPS (assuming it was online of course) then I for one don't mind helping you out with a few dollars.  Will this be an on going solution, or a one off fix?

The problem seems to be a current insufficient of staking chunks. More CBX would need to stake in order to stabilize the network.

If we can get the chain going again, I can get at least 2 more nodes up.
This chain needs need staking nodes, not just regular ones. It is worth to have some coins on those nodes, preferably divides into several inputs.

I'll try to move the chain today.

I suppose you had no luck there.

I believe your suggestion is mostly right: after 6 hours, all wallets consider themselves out-of-sync, at least when restarted. I also made a similar hack to try to move things around but unfortunately this time none of my current coin chunks meet the necessary criteria to stake: being still for 1 hour is not enough, although in practice it usually is. There is a flag called "stake-modifier". Your chunks can only stake if there is a block with this flag at least an hour in the future since your chunk was last moved/staked. And this is exactly my problem: most of my chunks are within an hour of that last block, so not eligible at all. I have 2 other chunks that are older than the current last block, just over an hour, but unfortunately the last 2 blocks in the chain (those over an hour for me) do not have the necessary "stake-modifier" flag so I cannot make them stake.
The solution seems to be someone with eligible chunks to try to stake hacking the wallet code and bypassing that 6-hour sync limit..

Nah, don't worry about that. I'm glad to help.

Btw, in Vault v3 there's an option accessible from the menu for an automated bootstrap load in case you prefer that over the manual, somewhat cumbersome, procedure.

Cheers.

Please upload Bootstrap.zip

I want to keep this online .
Also if possible upload latest version.
I see real potential in this project.

6 years seems to long to update.
Don't let me down Smiley

my Bootstrap got broken.

Br,

This is the most recent bootstrap for Vault v3:

It's a bit old, I know...

This may be nonsense but please bear with me:

Blake2b seems to be optimized for AVX2. Power2b just supports SSE2.
Assuming that power2b uses blake2b internally, and the latter is/may be optimized with AVX2, my question is couldn't power2b use blake2b's already existing AVX2 optimizations, and not fall back as a whole to SSE2?

X12 for  AVX2 is broken again, or should I say, still. I thought I fixed it in v3.11.3 but now I can't find a working version for AVX2.

I'm investigating.

Thanks.
Please also add to your list that phi is crashing in AVX2 immediately upon start.

Hi.

I was just wondering: in the current periodic share/speed report, is there the raw hash rate, the one the machine can actually compute? Not sure if the value in parenthesis is this number as it seems quite smaller than the value I got from older versions. Does --benchmark still output this value reliably?
Thanks.

There's another downside to specifying a custom cpu affinity. Whe using  the default
each thread is affined to a precise cpu, the one matching the thread number.
With a custom affinity mask it's more complicated so the thread is afffined to the "mask"
which means any of the allowable cpus.

I don't feel like doing the additional coding to do one to one matching of each thread
to a unique allowable cpu.

Affinity should only be needed if there is a good reason to run fewer threads and if the CPU
is an AMD. That's small set.


The almost-alternating masks on Windows was found by trial and error to yield the best performance with all the Intel CPUs I've experimented with (correction: for a few older ones, it doesn't make any difference in which case I don't set affinity). I just know that Linux uses a different numbering convention and that rules are different, but an alternating mask always seemed best on Windows. Or perhaps the numbering convention in cpuminer is not the same as in Windows Power Shell. I will try to incorporate the info you posted along with the new release and see if it makes any difference. One thing seems for sure: many times, using all CPUs is worse than using just a subset (memory/L cache ceiling somewhere? Maybe with more CPUs it's even worse), and using a specific affinity seems to always work better than using default one with a subset of CPUs.

Thanks and let's move on. Smiley

I've made some more tweaks and this is what I get  with -t 8 --cpu-affinity=0x5555
on Linux. I'l wait for your test results on Windows before I commit the change.

Also what is your goal? Why are you going to all this trouble with odd thread counts and
complex affinity masks?


I will do what you ask when I have the chance. I thought the problem was already clear that it would never set affinity to CPU# > 31.

What do you mean by "complex" masks? Why do I have to choose submultiples of the number of processors and why would it be better? In this last example, I set half minus 3. Changing some 5s to 4s in the mask shouldn't be considered "complex". Nor should 8 threads with a mask of 0x40404040404041 (8 throw better performance than 7  Wink ). Shouldn't they all work? I'm sure that when "simple" masks work the "complex" ones will follow.

Question: "half threads (28), default affinity": what is a pass in this test? Default affinity always works in that all CPUs are allocated to the process.

I'll send my results back to you by PM in order not to pollute this thread.
Cheers.

This CPU affinity crap is starting to piss me off. That's not what I came back for.
It's taking way too much of my time.

This all started with a request to support CPU groups on Windows. Windows is a
commercial product: it costs money to use it and takes even more money to
develop on it and for it. Enterprise level development (multi-socket, large thread
counts, NUMA, CPU groups, etc) costs even more.

Yet I don't get paid a penny.

From now on any requests for features specific to Windows must be accompanied
by a nominal non-refundable donation. I will do an assessment and determine if I can
do it with my skill level and resources and how much work may be involved. I will
then set a fee payable on completion. The fee will be scaled based on whether the
feature is for consumers or enterprises.

CPU groups is an enterprise feature. I will make one more attempt to fix the current
issues. If that fails I wlll remove the CPU Groups support and revert to v3.8.8.1 affinity..

I got you.
As a side note, I have no problem with CPU affinity not working. Like I said before, I set it externally exactly because it never seemed to be reliable. The only reason I'm doing all this troubleshooting is because you asked why I was was doing that (setting affinity externally) instead of using the built-in feature.
I don't need it fixed. It works for me as is. I just thought you actually wanted to fix it. And again, I'm not using CPU groups.

That said I definitely would prefer efforts to be directed to something more useful, such as performance improvements as well as new algos. So I think we're on the same wavelength.

Cheers.



CPU affinity still does not set correctly in v3.9.2.3. In Task Manager, it seems it still can't affine CPUs above CPU31. Also, some CPUs not specified in the mask are set.

Setting --cpu-affinity=0x55555545555544 with 56 CPUs:


Enough with the overly complex test cases. I've said it before DEFAULTS!

What are the defaults? Not setting affinity? The performance drop is significant in that case.

I was wondering about  that when I saw it but hadn't followed up (too much multitasking).

I think I found the problem, it's day 1. The argument to SetThreadAffinityMask is supposed to be DWORD_PTR,
not a DWORD, so "&affinity_mask" instead of "affinity_mask". It supports 64 CPU by casting the pointer as DWORD64_ptr.

It's all clear now. Thanks for your persistence.

Thank YOU for all your hard work.

Does this help?

Those CPU masks become quite weird with --cpu-affinity. And in the end, it's actually bound to CPUs 0-31.

Interesting, the errors occurred even with a default affinity. I looked deeper and discovered the mask
on Windows is only 32 bits as you suspected. I don't know how it's supposed to support 64 CPUs
with only a 32 bit mask.

With groups enabled the mask is of type KAFFINITY and a member of a struct that also include group info.
KAFFINITY was described as a bit mask to set affinity of "one or more" cpus in a group but doesn't specify
a maximum or further define KAFFINITY.

Maybe you should enable CPU-groups, but cpuminer-opt needs a custom build to use it.



Hmmm, that seems to be different between Win32 and Win64: https://stackoverflow.com/questions/10877182/getprocessaffinitymask-returns-processaffinty-and-systemaffinity-as-1-overflow. The parameter seems to be 64 bit under Win64 despite their deceiving name (type DWORD64...).

typedef unsigned __int64 DWORD64, *PDWORD64;

EDIT: https://docs.microsoft.com/en-us/windows-hardware/drivers/kernel/interrupt-affinity-and-priority#about-kaffinity: "The KAFFINITY type is 32 bits on a 32-bit version of Windows and is 64 bits on a 64-bit version of Windows."

Those CPU masks become quite weird with --cpu-affinity. And in the end, it's actually bound to CPUs 0-31.

Edit: I took another look at the code changes and there should be no difference if cpu groups
is not enabled. A change in behaviour means it's running different code. But if it was running
the new code the "Binding thread" message would have included the group. I don't know what's
going on.

You can still have cpu groups with fewer than 64 cpus.
 

If I had groups enabled, I would have a combo box like the one in this page. As I don't have it, I suppose I definitely don't have them enabled.
Thanks for analyzing this anyway. I'll still stick to setting affinity externally and ignore the warning.

What is confusing me is all your changes from the norm. I would like to see how it works
with defaults to get a reference. I also don't know what you mean by truncating to 32,
affinity is 64 bits. and you don't have more than 32 CPUs anyway.

I don't know the case you posted  but there were errors

Code:
affine_to_cpu_mask for 1 returned 57

repeated for many CPUs, seems to be all the odd numbered ones.

EDIT:

I can't find what error 57 means.

Some useful tests, you don't have to post the session just whether it worked as expected.
Running less than N threads should be by factors of 2. Anything else is YMMV.
And forcing the process affinity disqualifies everything.

1. All defaults

2. 14 threads default affinity, note wether cpu loads are balanced, ie affinity was properly
distributed.

3. If unbalanced try setting affinity 0x5555555 or  0xaaaaaaa

If everything works as expected I don't see a problem. Windows issues like CPU groups and
NUMA shouldn't be an issue until you get over 64 CPUs.

There are more than 32 CPUs (check the debug above: 56 CPU cores available, 30 miner threads selected.).
If I select all 28 even CPUs for instance, that means an affinity of 0x55555555555555 which is over 32 bits. If I do set --cpu-affinity=0x55555555555555 , I can check in Task Manager that affinities for CPUs above CPU 31 are not set, which led me to think that affinity is truncating to lower 32 bits.
I do think the warning is just that: a warning, but wanted to be sure as v3.8.8 did not issue such warning before.
And yes, there is no warning issued if I use --cpu-affinity (or don't use it at all) as long as I don't set affinity externally beforehand, so that is not an issue.

EDIT: I made a few tests and verified the following:
* With v3.8.8, a cpu affinity works correctly up to 0xffffff; above that, it triggers that exactly the first 32 CPUs are used, no matter the value.
* With v3.9.1.1, a cpu affinity works correctly up to 0xf; above that, it triggers that exactly the first 32 CPUs are used, no matter the value.
I verified this by using the CPU affinity option in Task Manager for the miner process.

So the reason I set affinity externally is because I could never rely on the built-in cpu affinity for most miners. It seems to break in some configurations.

I suggest you not set the process affinity explicitly, it confuses cpuminer. Also please add  -D option
and post output.

I'll have to set it explicitely for now because --cpu-affinity truncates to 32 bits, thus not allowing the use of CPUs above 31.
Sorry, I'm not sure on what situation you want me to post the debug.

Is this enough?

A few points. and questions:

What's your CPU and OS?

[...]

Do you use CPU groups? Which version of Windows? You said you affine the process seperately and that
causes problems. That could be related to CPU groups if the process is in a different group from the miner
threads.


Tested on Intel(R) Xeon CPU E5-266O v4 @ 2.OOGHz CPUs, on Windows Servr 2016.
I do not use CPU groups (not sure what those are: will look into that) and I tested with 20 CPUs. [EDIT: I checked and CPU groups are applicable to machines with more than 64 CPUs so I only have one group here]
I open a command prompt and prior to launching cpuminer-opt I set the command prompt's affinity to the one desired (set to 20 CPUs). The miner then runs with the desired processors already affined. v3.9.1.1 now complains that it can't affine to all CPUs (obviously, because I removed some from the parent process). I'm supposing that's just a benign warning and nothing will really change. You probably made the miner explicitely affine to all CPUs by default on startup hence the warnings.


Yescrypt performance:
There were no changes to the yescrypt code. I added yespower and tinkered with using that code for
yescrypt without success so I left yescrypt as is. If you are aware of a better performing miner
please point me to it and I'll have a look.

Argh, I'm sorry. I meant yespowerR16 instead of yescryptR16 in my last item! And I was referring to bellflower2015's fork of your miner (you can easily find it on github).

Thanks!

* I'm consistently getting about 5% less hashrate for yescrypt than with older v3.8.8 for the exact same configuration. I didn't take more metrics but I think some other algos have slightly less performance as well.

If they are compiled with MinGW, the performance will be lower. Cross-compile with GCC does a better job optimizing
If it's not the case, it might be something in the recent changes

In both cases, I'm using the official Windows binaries.
