while we are on the programming topic... I really can't stand the misuse of logs to pass information/variables between the scripts. not only that the logs slow down everything, they are killing the usb sticks, causing all kinds of problems, hangs, freezes, etc. and i see more and more people are recomanding usage of screenlog

how about using named pipes (fifo) to pass info between the scripts. nothing is saved/logged by using a named pipe and it is much faster. leave the logs for what they were really ment to: to record problems

example: we want to get the fan speed and temps from the temp control so we can send it trough telegram. the easy solution is to write all those values from the temp control script into a log, then read from the log and send telegram. the problem is that in order to satisfy the telegram, the temp script has to write line by line that info for each gpu into a log, 24/7 so that the info is there when telegram needs it.

if we rewrite the temp control to keep sending all that info to a named pipe, the info will be there when telegram needs it without writing to a log over and over, 24/7, and write to a log only critical info/errors that would be needed for troubleshooting

i started rewriting the temp control and i intend to incorporate the named pipes but that will break compatibility with telegrams, web stats, and whatever else is fetching the info from logs. i just can't find enough free time to rewrite all the scripts in nvoc

if interested in the development and optimization of nvoc, please google "bash named pipe" and research then share your thoughts, maybe we can split the workload if you are interested

My 2cents:

While the use of named pipes should certainly reduce disk IO and save folks USB sticks, the burden would be shifted to memory. While not a problem for me since all of my rigs happen to have at least 16G of RAM, I know of several users of nvOC that go minimalist with both CPU and memory. I think the current memory usage is around 2G for nvOC so these folks build rigs with only 4G of RAM. So, when you consider the price of RAM versus the price of a small SSD, disk is cheaper. I can buy a $33 60G SSD but 16G of RAM will cost me $130.

The bauty of named pipes... read here a brief explanation:

unlike ramdisk, it doesn't consume memory nor it uses disk I/O

Thanks a lot mate.
It was always a question for me what those loops are for...
Tested the miner start script without the loops and all is good.

I think as you said its some legacy code from old nvOC and can be removed.

And as I said before that wtm-miner is just a copy of 3main miner starts so wtm auto switch dont restart 3main which will take so long and just switch miner.

I rolled a version of 3main without the loops this morning and tested it with poor results. It would appear that the miner runs but the watchdog kills it because of low utilization after the 70 second grace period. So, what I think is going on here is that we need 3main to continue to run not because of the mining screen but because of the OC and PL settings. When 3main ends, those go away, and the miner starts performing poorly. What I did to fix it was to add a single infinite loop at the end of 3main to make sure it never exits. So, at least we can clean up 3main substantially by removing the 30+ instances of that loop. My version of 3main is left with only 3 - two in the SALFTER sections (because I haven't bothered to figure out what is going on there) and the one I added back in at the end.

Can you try enabling persistence mode

Code:

nvidia-smi -pm 1

remove the loop at the end and try if this fixes the utilization after 3main exits

Of course it uses memory. It says right there that the kernel handles it which means kernel memory. So the kernel grows in size to accommodate the pipe contents.

Hi, what about full support of Asus b250 mining expert.

What does it mean "partly supported"?

Is it a hard limit of 13 standard GPU + 6 P106? or will be possible to use 19 regular GPU?

My mobo does not even post bios messages when Iam inserting 14th regular GPU

Could anybody comment on this?

Thank you in advance!

Have you attached 3rd PSU?
One PSU = 7 GPU
Two PSU's = 13 GPU
Three PSU's = 19 GPU

Partial support means that not all GPU's can be overclocked, first 16 GPU can be overclocked, last 3 GPU will work on stock settings. See the post from two pages back regarding TB250

https://bitcointalk.org/index.php?topic=1854250.msg23785755#msg23785755

I have attached just 1 PSU (3000watt) and attached 13 regula GPUs - they are fine, but when I am attaching 14th GPU - mobo does not even post any messages and does not start at all.
And I am talking about *REGULAR* GPUs, not P106!
Did anybody start this mobo with 14 and more *REGULAR* GPUs ? NOT P106

Thank you

What I meant by separating the miner start codes from 3main, is what I'm already doing in my latest WTM.
3main handles wdog, temp, power limit, ... and the miner start up,
It does not need to have miner start codes inside, but can just fire up the script that have all the startups inside.

In my latest switch, 3main starts the first mining process and sits back, then wtm switcher checks for better coin , stop mining process and start new one by just executing the file I put all mining startups inside without any loops (callled it wtm-miner)

3main now has over 3500 lines, which over 2500 lines are miner startups, with over 80 loops for miners.

Woah. I get some really odd behavior when I do that. The OS seems to want to hold onto 3main so trying to edit it locally ends up with vi being killed. Also, the temp script keeps getting killed and restarting yet the watchdog continues to run as does the miner. Needless to say, that is not a stable configuration but for different reasons than one would think.

I added the nicehash stuff to the wtm autoswitch coins if someone is interested.

1. ADD to the WTM coins in 1bash.

Code:

NICE_SKUNKHASH;NICE_EQUIHASH;NICE_ETHASH;NICE_NEOSCRYPT;NICE_X11GOST;NICE_CRYPTONIGHT;NICE_LYRA2REV2

2. in WTM_AUTO_SWITCH Change
From:

Code:

# filter WTM coins by user selection only
for i in reversed(data):
    if i["tag"] not in includedCoins:
        data.remove(i)

to:

Code:

# filter WTM coins by user selection only
for i in reversed(data):
    if i["tag"] == "NICEHASH":
       i["tag"] = "NICE_" + i["algorithm"].upper()

for i in reversed(data):
    if i["tag"] not in includedCoins:
       data.remove(i)

3. in PAPAMPI_WTM change the TOP_COIN=
to :

Code:

TOP_COIN=$(cat WTM_top_coin | grep : | sed 's/:[0-9]*//')

4. ADD to your coins in 1bash

Code:

NICEHASH_BTC_ADDRESS="Your nicehash BTC address here"

#NICE_LYRA2REV2
NICE_WORKER="$WORKERNAME"
NICE_ADDRESS=$NICEHASH_BTC_ADDRESS
NICE_LYRA2REV2_POOL="stratum+tcp://lyra2rev2.eu.nicehash.com:3347"
NICE_LYRA2REV2_INTENSITY="21"

#NICE_NEOSCRYPT

NICE_ADDRESS="$NICEHASH_BTC_ADDRESS"
NICE_NEOSCRYPT_POOL="stratum+tcp://neoscrypt.eu.nicehash.com:3341"

NICE_ADDRESS="$NICEHASH_BTC_ADDRESS"
NICE_CRYPTONIGHT_POOL="stratum+tcp://cryptonight.eu.nicehash.com:3355"
NICE_CRYPTONIGHT_INTENSITY="21"

#NICE_X11GOST
NICE_WORKER="$WORKERNAME"
NICE_ADDRESS="$NICEHASH_BTC_ADDRESS"
NICE_X11GOST_POOL="stratum+tcp://x11gost.eu.nicehash.com:3359"

NICE_ADDRESS="$NICEHASH_BTC_ADDRESS"
NICE_SKUNKHASH_POOL="stratum+tcp://skunk.eu.nicehash.com:3362"
NICE_SKUNKHASH_INTENSITY="21"

5. ADD to 3main or wtm-miner for latest version

Code:

Thanks mate
I tried to put your edits in codes to be easier to understand.

But we already have a nicehash auto switch, is this one needed ?

Hi Papampi

I don't like the nicehash switch because it is mining nicehash only. your script is switching from nicehash to any other coin in the list and back. i totally love your script.
