Topic: [ANN] [PASC] PascalCoin, true deletable blockchain - V3 Hardfork on block 210000 - page 20. (Read 990783 times)

The link to polyminer is right there... except there is a 1 behind it... polyminer1... seems to be what you looking for.

I see lots of C/C++ code... some of it is related to randomhash, some of that could be avoided with a delphi to cuda interface library which I have but no others are on the internet as far as I know... so some unneccessary work was done, then again all that c/c++ code will benefit somewhat from c/c++ compiler optimizations perhaps not a lot though. Then there is additional c/c++ source code not really related to random hash only but also stratum and pool mining and such...

Overall it's somewhat interesting... I have GT 520 with only 48 cuda cores... I think this is a fermi based cuda card. I might purchase a GT 720/730 or something like that... which will have 384 cuda cores but still passively cooled and even cooler than GT 520 Not sure what architecture GT 720/730 is or something like that... the asus manufacturer version with blue heatsink. Will look into this later, might also give a nice boost to world of warships Will have to order it online though... cause like PC shops probably don't have it.

I will still try this polyminer/rhminer on this cuda fermi architecture to see if it can work on that as well, if not might require some recompiles here and there and maybe adjustments... older cuda architectures seems supported to... so not sure if rhminer use special cuda 9 features or something... it might though... problem for my machine is visual studio 2017 community edition completely fucked up the installation and deinstallation and probably won't ever work on this system, though this reminds me I do have a windows 10 virtual machine with visual studio 2017 community edition installed, this could probably be used to test/compile this c/c++ source code... that's a little bit interesting... it would be a bit slow to run this vm but doable... could even install additional software... old vmware 8 software though, 32 bit even... but enough to run this... though no cuda support probably... I wonder if newer virtual machine software can "pass through cuda..." like "pass-through graphics drivers" hmmm...

Today there will probably be an AMD presentation about "next horizon"... probably chiplet design of new processor. I also watched some benchmark results. Zen/Threadripper 2920x processor seems like a nice choice if I were to build a new system... this processor can do it all, be productive and still game... the higher models have gaming issues with infinity fabric... the higher models have memory latency issues cause it most be passed from core to core which kinda sucks. I hope their next design will be many cores around a single memory chip to keep memory latencies consistent... that would be awesome.  Then I may wait till 2019 to buy such a system. There is another somewhat problem with this 2920x (promontory chipset) it probably contains hardware backdoors, but nowadays all hardware is pretty vunerable... so perhaps this is a somewhat mute point, but still a concern...

I was wondering what this rhminer thing was during the testing... so now I know... thx jason for informing us about polyminer1's rhminer for cuda and such... not sure if it also runs on opencl (?) anyway was polyminer1 paid to do this work ? I would guess so ?

https://github.com/PascalCoin/PascalCoin/blob/master/PIP/PIP-0020.md

Perhaps not though, this pip does not mention anyway salary/payment figures

This rhminer does have option to either pay or not pay 1% to polyminer I wonder what happens if it is disabled... will it do something weird then ?

@Jason what are your plans for your coinotron mining pool ?!? Will all your miners upgrade to new randomhash mining software ? How is that proceeding ?

Also does anybody have any idea how this will affect nanopool ?!?!?

I am not sure if polyminer1 read this thread my question for him would be:

1. Did you "profile/benchmark" randomhash with delphi/pascal code first to see where major bottlenecks occur in randomhash ? Or was randomhash simply converted to c/c++ without doing any bottleneck/performance analysis in delphi/pascal code ?

I did try that.  One server node and few local mining nodes.  I only have one IP address.

Would you happen to have the link to the miner source code?  I have been using the one from official repository.  It compiles and runs fine.
But Polyminer worked on RandomHash, so I would rather use his code.  He probably has GitHub.  I shall look for it later.

Thanks.

The RAM speed does not matter.  Any RAM will do.  I am running single channel DDR3 on my gaming computer.  Bandwidth of 9GB/s on a good day.  Latency horrid.
I read the PIP-0009.  It's for low end hardware.  That means any old junk will do.
The whole point is to keep the network running without wasting electricity.  Core 2 series used 65 nm process (I think), which generates as much heat as today's low end 14nm process. 
Ryzen 5 series for example.  They are terrible in terms of heat/performance, but affordable.

You started with "I found a free laptop", now you have 7 dream PCs.  Please keep the forum clean.

Heya Folks,

Even my DreamPC from 2006 was cable of mining a few blocks/coins. Will keep hash rate secret for now lol.

The fastest core did it, core 2 (2.0 ghz and much slower memory probably then todays machines ).

It is possible to include spaces in the miner name by using -n "Miner name".

So encapsulate it with " " in batch file/prompt commands to do it right.

For the time being all miners stopped maybe later I will do some more testing =D thanks for testing guys ! =D

Bye for now,
  Skybuck.

Those are not special machines.  Windows 10 gaming computers.  VR (add any catchphrase here) ready.
I build them to last.  I do pro music  (DAWs are very hard to build right), graphics, video too.  The CPU will be the bottleneck when it throttles.

Those i7-4770ks BTW.  I paid 300$ for.  For 2 of them used.  Newer tech doesn't mean faster.

The CPU socket needs to be able to dissipate 120 watts of electricity (in 4770k OC case).  A fan cooler won't do.

Again.  Don't mine on a laptop.  And even with a desktop grade CPU.  Don't load all the cores on an air cooler.
I had 3 cores loaded and was able to play Worms Revolution without any slowdowns.

Hint:  I rarely use Windows.  On Linux, install lm-sensors.  And run .  You can see the temperatures of most common parts in real time that way.

The Beast actually runs Linux.

Ahh, too bad. I liked it when it was CPU only. 

Hey tlaskow... thx for the pictures... funny to see rig involved.... kinda noticed this on the testnet4... i7... 8 cores or something...

Here is a hint... my dual core AMD x2 3800+ can only do 1/20 th of your machine !  if both cores running.

I will however try and optimize the randomhash code here and there to see how much I can squeeze out of it

I think you wrong about the gpu/asic part though.

The GPU hash algorithm is still present in the pascalcoinminer... but it will become completely useless soon... I tried mining with it... but it gives wrong results for pascalcoin v4.

Mining must be done with the -C option on the testnet v4 as far as I can tell.

And since this code randomhash and such is as far as I know pascal only at the time being there is no real way of running this on a GPU... it would have to be converted to C first... or some "magic" pascal to "intermediate" and then to ptx/opencl/cuda or whatever... don't think such a compiler exists yet though I could be wrong

The sha256 part of randomhash might be executed on gpu... but randomhash uses many many many hashing algorithm... so this would give it a slight boost.... but the source code of the pascalcoinminer would first have to be adjusted a bit...

Here is a question for you:

Did you already try to optimize randomhash while running it on testnet v4 ? Did you change any code yet ?

Oh in regards to your rigs.... Yes they do look fine... their aircooling look fine.... I would still be a bit worried about my own rigs though... they may even have better airflow... but what kind of stress can memory chips truely take ? Hmmm... Well you have been running it a lot... so for now I would guess it's probably alright for now...

The laptop overheat... probably related to CPU just getting to hot... so maybe I got a little scare there.... I have never really hard of a system overheating because of too much RAM activity... so I may be way off... or perhaps this is something new... I am just not sure... and I don't have a real way to tell...

But perhaps in the future hardware will have temperature readings on RAM chips as well... that be nice

Building special machine is probably the way to go for cryptocoin mining.

But this is also why it may fail... the idea of "average joe" mining on his "main rig" is probably an illusion... most people will probably consider their computers to important to do this... especially if it's work related...

So these cryptocoin miners... do provide some service and are running servers... so the idea of "distributing" cryptocoins fairly... is slightly flawed... ofcourse anybody could buy a second computer and just run it on that... (most people probably won't do this though thinking it's a waste of money... so in that sense this distribution idea is flawed...)

* update *

There are still a few days before main net switches over... so this should give some days of more testing on TESTNET v4.

Later today I will leave the laptop on running at 1 core or so... with 1 miner... just to see if "my" laptop can still get some coins VERSUS your BEAST ! LOL.

Pls leave beast running as normal... just to see if """my""" laptop can get some coins "fairly" too

Since I am using internet connection sharing... might as well launch this f*cker now so I can keep an eye on it...

Shitty german laptop here it comes ! =D


*** UPDATE 2 ***:

HAHA !!!!

Success !!! =D LOL.

Shitty German Laptop was able to mine a block on TESTNET v4 !

See block number 146693 on TESTNET v4 safebox/blockchain ! =D

I am starting to like this new hashing method ! LOL =D

*** Update 3 ***:

I can mine on laptop with 1 miner, with two miners the laptop overheats and shuts down ! HAHA. At least that's what I think is happening. It's kinda weird though... it's not even getting that hot... perhaps there is some heat setting somewhere... This time I also "lifted up" the laptop a little bit... to let cold air flow under it... still overheated/shutdown hmm...

Will try my DreamPC next for the fun of it... hopefully it won't get damaged Don't think it will... bit risky but fun. It must update the blockchain first though... hmm..

Bye,
  Skybuck =D

No.  GPUs and ASICs will still work.
It's a hard fork, but it doesn't mean the original PascalCoin hash algorithm is being "abandoned" for those who can afford tens of thousands in hardware. 

Pascal Coin project technology team is strong, technology and marketing capabilities are first-class, the future development is worth investor's optimism.

PASC is going back to CPU only mining?

Heya Folks,

Today is the first time I saw RandomHash in action, it was quite amuzing (why is secret for now). Unfortunately my main CPU is probably a bit too slow to compete with modern CPUs though with a bit of luck maybe some mining can be done, or maybe some parts of the randomhash can be executed on gpu though I am not yet sure if there will be CPU-mining pools I would guess so which might make mining with a single CPU useless anyway.

However that is not the main reason I am writing this.

The main reason is this:

I just tested the new miner on a very shitty german laptop which I got for free from somebody... I ran multiple miners on it... and after only a few minutes the laptop shut off... it probably got to warm.

This is a little bit alarming really ! Cause this laptop was able to game, but somehow it shuts off... I did kinda let the laptop fall while setting it down near a candy carnval shop not sure if that has anything to do with it and it also has driver/IRQ blue screen issues probably cause I stopped some services or maybe there is some other damage... not sure though...

Hover this shutdown seemed different... total black screen and simply power down.

What I am concerned about... even on my main system ! is this:

RandomHash alledgedly uses some "memory algorithm" which is supposedly hard to run on a GPU and it's memory chips, so now instead it will run on CPU/MAIN RAM right ?! (The gpu option of the pascalminer is not to be used... ?! instead cpu option !)

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!! SO THE ISSUE/WARNING ALERT IS THIS: !!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

RandomHash will make your memory chips RUN HOT !!!!

!!! Probably/maybe much hotter than normal !!!

And at least on my hardware there is no way to check the MEMORY TEMPERATURE OF MAIN RAM ?!?!?!?!?!?!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So as far as I am concerned this is a very bad and dangerous situation.

I can monitor CPU core temperatures fine with CPUID HWMonitor tool/software. I can monitor GPU cores with GPU-z and such.

But here is my point:

Monitoring the temperatures of memory chips is unheard of as far as I know ?!

My hardware is old though.

Can your hardware and software monitor your memory chip temperatures ?!?!??!?!?!??!???!?!!!!?!?!?!?

If so please backup any claims with screenshots as proof !!!!! )

Note:

I have been through the experience of having a RAM memory chip develop 1 single bit error probably due to heat, static discharge can also not completely be ruled out.

This was a very scary experience which lead to file to file copy corruption and zip corruption and cd/dvd burning corruption at the time... very scary.

I would definetly not like to go through something like that again.

So this is a big worry right now.

Nobody really knows what kind of HEAT and STRESS RandomHash will cause on main RAM memory chips.

Perhaps this very shitty german laptop is a very fortunate thing to happen... without it... this potential issue may have remained hidden for some time... until much later... when better ventilated systems might also start showing damage because of this. Now the issue was immediately detected by this shitty german hp laptop with intel hardware/cpu in it.

I have used my current main system for 12 years and I am pretty confident it can handle all kinds of memory stress/loads cause god knows I have stressed the shit out of it with all kinds of softwares lol and test programs.

However RandomHash might be something totally different/something totally new that may tax RAM chips like never before ?! So I am slightly worried about this.

It seems to only use 1 or 2 MB of RAM or so from these chips (according to pip/documents, not evaluated via monitoring tools yet), but this specific section will probably become pretty damn hot !

Now imagine running this for 24 hours non-stop ?!?!?!?!?!?!?!??!?!?!

You may be risking damage to your RAM chip ! So consider yourself warned.

I hope to god that I am wrong... cause it would be cool if I was wrong... but this laptop shutting down might be a sign of things to come...

For your information: This laptop was used to run a pretty hot game: "Master of Orion"...

Hopefully the shutdown is not related to heat... but I am pretty damn sure it was... because the FANS started spinning up like crazy.

First miner: it was like ok... little bit of fan spin.

Second miner: wow... much more fan spin...

Third miner: fans going super load/max for a laptop...  few seconds later... BAM laptop shuts down...

This was an i3 core laptop 2 real cores 2 logical cores.... so this thing has hyper threading...  maybe it was a hyper threading bug but I don't think so... maybe the laptop has special overheat protection software or maybe it's just the CPU inside forcing the shutdown... or perhaps some motherboard sensors near memory chips shutting this thing down. Pretty sure it's heat related though. (So I don't know exactly what happened cause I don't know this fucking laptop that well lol... but it was pretty damn scary ! it rarely or almost never did this during master of orion... not that I can clearly remember... maybe one time or so... maybe two times... but then I shutdown many services... currently it has some services which may not be necessary but nothing to bad... before running the software the system was pretty idle... so I don't think these services are contributing to much to heat... though I could try and shut some down... I don't think it will matter measure... and the overheat/shutdown result will probably be the same. Perhaps because this enclosure is so small... the heat from the memory chips reaches cpu sensors... ofcourse I could be completely off the mark... and perhaps it's the CPU itself that is totally overheating... that could be and would be very funny as well... then intel's/hp products truely crap then again one might consider this some abnormal heat/load detection by advanced software and shutting it down out of precaution... though it more seems like some shitty overheat situation which is simply bad product design... your mileage may vary... very interested in hearing about any other systems shutting down because of overheat ! )

Here is my question for you:

"How the fuck are you going to measure your RAM chips temperatures ?!" Would love it if somebody could actually do this ? =D

Bye for now,
  Skybuck.

Don't worry Poloniex will update to the new version.

For Poloniex support, you need to contact them.
They take forever.
My coins were there for 7 months (missing from the blockchain/stuck).  Now on local wallet.
That's a huge risk if you ask me.

Hey all, what is Poloniex doing for the fork?  That is where my coins are now. 

RE.  TESTNET.

I put two 4770ks on it last night (old gaming computers).
It's still going.  I was curious how Windows binaries compare to Linux.

 

I don't have Windows.  My MacBook died and I cannot afford another one.  It ran Windows.

I have been trying to fix it for several months.  It's non-repairable.



 

@nightraven
@polyminer
@jason

How many blocks per month would an AMD Ryzen 7 2700x be able so solve?
I ran the TESTNET on various old CPUs and have no clue which one to use.

I have this one.  But it only has a fan controller with fans hooked up to it.   

Thank you.

That answers my question.
BTW.  I do want to mine and help to keep the network decentralised.

Best,

~Thomas

Keys does not need to be available on the Hard fork, they are independent.

If you want to mine, keep the private key in a safe backup, otherwise if you lost it your mined coins will not be accessible.
