pipe closed by peer or os.write(pipe, data) raised exception. about silentarmy

[mbevand]

Can you try running:
sa-solver --nonces 100

This will either work or show you the exact error.

[Ajworry]

i have same error when write param --instances , without it works normal

[mbevand]

@Ajworry "pipe closed by peer" is a generic error message that has many different causes. What --instances values cause you to see the error? 1, 2, 3, or more?

[Ajworry]

every instances. without param instances work normaly

@Ajworry Can you try the troubleshooting steps "Basic Operation" and "Correct results" as per https://github.com/mbevand/silentarmy/blob/master/TROUBLESHOOTING.md ?

Hmm what about:

[Ajworry]

bill@server1:/mining/silentarmy$ xauth list | sed -r 's,[0-9a-f]{32},XXX,'
xauth: file /home/bill/.Xauthority does not exist
bill@server1:/mining/silentarmy$

[mbevand]

Ok this is your problem. I need to understand why you are missing this file. Are you logging into your Linux system, using the graphical console, as "bill"? Or are you using some equivalent of "sudo -u bill" or "su - bill" ? Are you ssh'ing remotely?

[Ajworry]

i am logging thru ssh, driver fglrx 15.302 / ubuntu 15.04 server / gnome desktop login automatic as bill

[mbevand]

Instead of fixing your specific issue, I pushed a general fix that helps silentarmy ignore these errors: 438cdbc

"git pull && make" and can you report the output of "./sa-solver" as well as "./silentarmy" (even if it works).

works but not well

[mbevand]

What are your hardware specs? Is this really on an R9 390?

$ ./silentarmy --list

[Ajworry]

works i reboot it and working but i make OPTIM_SIMPLIFY_ROUND 1 and sa-sover show 1.2GB

[mbevand]

After setting OPTIM_SIMPLIFY_ROUND you need to recompile with make.

[Ajworry]

sorry my fail thanks

[cesarreynab]

@mbevand Is it possible to add an option like -o, --optim in command line so we don't have to change the param.h?

[Ajworry]

and my specs are
asrock-h81-pro-btc
intel-celeron-g1840 maybe this slowing mining
crucial-ballistix-tactical-8gb-2x4gb-ddr3-1600
kingston-ssdnow-v300-120gb
6x sapphire-nitro-r9-390-8gb-with-back-plate

45-50 sol/s one card 2 instances and OPTIM_SIMPLIFY_ROUND 1

[mbevand]

@Ajworry Ok so your perf looks good.

@johiro I will consider it. Pull request are welcome to implement this.

@yjdwbj Don't forget to let me know what "sa-solver --nonces 100" reports.

[killermonk]

I'm getting the following when I use sa-solver --use 0. Is my card not supported?

@killermonk Your card/OpenCL implementation is probably not supported. Sorry, SA is currently not maintained any more.

[CER2811]

Hi.

As far I could check my silentarmy version already contains the 438cdbc patch but still getting that pipe close exception. I ran sa-solver --nonces 1000 and got the following:

Total 1824 solutions in 77748.8 ms (23.5 Sol/s)

After I ran --list:

eu@eu-MS-7345:~/silentarmy$ ./sa-solver --list
./sa-solver: /usr/local/cuda-8.0/targets/x86_64-linux/lib/libOpenCL.so.1: no version information available (required by ./sa-solver)
Devices on platform "NVIDIA CUDA":

What do you think is going on € (oddly no question mark on my keyboard)

Thanks.

@Ajworry Can you try the troubleshooting steps "Basic Operation" and "Correct results" as per https://github.com/mbevand/silentarmy/blob/master/TROUBLESHOOTING.md ?
