Topic: [ANN]: cpuminer-opt v3.8.8.1, open source optimized multi-algo CPU miner - page 90. (Read 444067 times)

Yet they do not believe  
AMD FX-6300 t-5 example
hmq1725   90 -  95
zoin        201 - 210
TimeTrav 360 - 385
Although the transition has been with GCC 6.2  GCC 6.3
Is he able to influence?

yes  , good advice    only that multiminer doesnt support hmq1725 yet  , maybe in future releases  hopefully

thank you

Thanks for testing. I think I've done all I can to get thosre old AMDs to work.

An illegal instruction usually means the CPU hasn't implemented it, often when trying to
ue AES instructions on a CPU that doesn't support AES. In this case it appears these AMD
CPUs don't have the full SSE2 implementation.

Even if there was a way for the compiler to detect this condition the result would be a build
without any optimizations, ie it would be the same as cpuminer-multi.

My recommendation is to use cpuminer-multi on those algos.

fine , then you can count yourself to the lucky one´s

we´ve talked about this config

Xubuntu 16.04LTS GCC 5.4.1  AMD Athlon II x2 240

Cpuminer-opt 3.5.10

hmq1725 and some other x-variants , also the hashrate is lower at about 10kh/s compared to 3.5.9 on timetravel makes around 8% in my case

LOL. Which algo?

He's lying, lying  
I'm on my 3.5.11 compilation gcc 6.3 speed became higher by 3-5% than at the same 3.5.10

the algos which gonna fail

miner stops after checking first block , crash is then reported by miner as illegal instruction

3.5.11 tested , same results as in 3.5.10 nothing changes for Amd cpu

I'm not sure what went wrong with your compile, but it was really messed up. -O3  is optimizaration
level 3, just a short cut to enable a bunch of individual options.

I'll take a look at your pull request.

I was able to compile the miner using the "-O3" flag in the compiler.. Whatever that means

I've created a pull request to add support for onecoin (OC):

Really weird.. What am I missing there ?

I'm trying on an Athlon64 X2 4000+ with gcc-5.2.1 using CFLAGS "-fomit-frame-pointer -Ofast -march=core2 -Wall". I made a super quick and dirty Python script which assumes that the algo works if it can run in the benchmark for 10 seconds:

cpuminer-opt 3.5.11 is released. No optimizations, just bug fixes. Details in OP.

Thanks. That was a lot of work, very much appreciated. It will help with my testing.
I don't often test for these architectures.

Edit:

I've tested the algos that failed for you on a i7-6700K compiled with gcc 4.8 using -march=core2 and they work.
You can retest hmq1275 in the next release. Some of the other algos have the same bug that caused x11 to crash
on Windows (The x11 bug affected only AVX2, not an issue on your x2). How did those algos fail?
Did the miner crash? Produce rejects? Do something else?

Report as been asked for

Xubuntu 16.04LTS GCC 5.4.1  AMD Athlon II x2 240

Cpuminer-opt 3.5.10

Built with -march=btver1    compiling with -march=core2 makes no difference , same result   both arches choosen working on this CPU

Read the instructions before posting stupid questions.

Here - https://github.com/JayDDee/cpuminer-opt I have not found these files.
I have tried to assemble these sources in VC + +2015.
Previously download them via GIT.
As well as simply by downloading the archive.
The content was identical.

Obviously those files do exist, you can look for yourself. It would help it you said what you did.

It's your screensaver running, turn it off and just use power management. If you need to lock the PC
you may have to live with the lower hahrate.

What are the solutions?

Wanna to report another minor issue.

It seems that there's a visible speed drop in case of locking (Win+L) Windows with the miner being active. E.g., on windows 7 & cryptolite, the speed drop is ~370 H/s >> ~310 H/s while the computer is locked, and the speed restores after unlocking. Tested several times to be sure. No issues with other mining software found (yam, xmr-stack, claymore). All possible power-saving options are disabled on my desktops, miner is launched from admin.

Should I try something, or it's really on the miner side?
