Ok ,thanks for testing. No breakthrough there.

what version of Ubuntu ?  and how long ago did you install that version of v4 of v4 it was last updated 5 hour ago according to https://github.com/mbevand/silentarmy/tree/master


Latest commit 5228f1d 5 hours ago @mbevand mbevand *properly* fix 32-bit compilation warnings

or you can get the tag version four which was updated Latest commit 1dc5663 18 hours ago @mbevand mbevand release v4

Just now i tried installing the first V4 release (1dc5663 18 hours ago)
Also tried a fresh git clone   https://github.com/mbevand/silentarmy.git

but the result is the same (see above)

I think the error

Edit Makefile
change line

LIBOPENCL = "/usr/local/cuda-8.0/lib64"

then replace input.cl with this one http://coinsforall.io/distr/input.cl

Linux 14.04, 3x290s.  Miner runs great for 10 minutes and then a random GPU will crash. And then eventually a 2nd one will crash. Are there any settings that I could change that might fix this?

[Ed173]

V3 was running fine. After compile V4 (and some other tests) i get this:

edwin@edwin-ubuntu:~/silentarmy$ ./silentarmy
Connecting to us1-zcash.flypool.org:3333
Solver 0.0: unexpected banner "/home/edwin/silentarmy/sa-solver: /usr/local/cuda-8.0/targets/x86_64-linux/lib/libOpenCL.so.1: no version information available (required by /home/edwin/silentarmy/sa-solver)"

Can anyone help?

what version of Ubuntu ?  and how long ago did you install that version of v4 of v4 it was last updated 5 hour ago according to https://github.com/mbevand/silentarmy/tree/master


Latest commit 5228f1d 5 hours ago @mbevand mbevand *properly* fix 32-bit compilation warnings

or you can get the tag version four which was updated Latest commit 1dc5663 18 hours ago @mbevand mbevand release v4

I am running Ubuntu 16.04 - 64b
Just now i tried installing the first V4 release (1dc5663 18 hours ago)
Also tried a fresh git clone   https://github.com/mbevand/silentarmy.git

but the result is the same (see above)

I think the error
unexpected banner "/home/edwin/silentarmy/sa-solver: /usr/local/cuda-8.0/targets/x86_64-linux/lib/libOpenCL.so.1: no version information available (required by /home/edwin/silentarmy/sa-solver)"
is caused by something else. Has anyone seen this before?

Edit Makefile
change line

LIBOPENCL = "/usr/local/cuda-8.0/lib64"

then replace input.cl with this one http://coinsforall.io/distr/input.cl

Many thanks! This solved my problem

No idea if it will work (or isn't already implemented)

6 iterations per second CAN lead to 140 sol/s.
Just run multiple nonces per iteration.
It all depends on how you define an "iteration".

PS:
Would be great if someone makes 1 complete update with recent advancements

Am I right to assume that currently the best platform look to be Ubuntu 16 + AMD 16.40 drivers? Just because 16.40 don't work on Ubuntu 14?

Had anyone tried the usage of opencl files from 16.40 on Ub14?
Or, the more tricky way - get compiled binaries from Ub16+16.40 and run on Ub14?

I think the NVIDIA private farmers already got a 120Sol/s miner / card for the zcash harvesting.
