no overclock on any of my cards.  cards work fine individually, but not together.  I only have two cards.  can you run whirlpoolx using -d 0,1 (so you'd only run two cards), and does that work? thanks

guys ... sp ccminer works perfectly with all workers - and all workers have a minimum of 5 cards in them ...

cards are gigabyte 750ti oc lp ...

if you guys are overclocking - then the clocks are too high for one of the cards to handle ...

tpruvot ccminer works with multiple GPUs under Linux.

STRATUM CONNECTION ERROR--

I am now able to run both your and KlausT's ccminer with whirlpoolx algo.  I get about 150mh/s with +225mhz core and -500mhz memory settings.  My card crashes with +250mhz, or +260mhz settings when actively linked on stratum.

There was something wrong with the stratum link, not the hashing.  I kept getting the red "retry in 30 seconds" message.       --scryptr

I there some other algo improvements on this Klaust's fork. I really cant find any sense at whirlpoolx..

I have to reach a flight, don't have time to merge.

In the mean time you can check out klaust's fork. version 2:

https://github.com/KlausT/ccminer

He has submitted some fixes on the whirlpoolx.

OC SETTINGS and HASHRATE--

I went to using a command line batchfile and your OC settings (+260mhz core, -500mhz memory) and my hashrate improved to 153,200kh/s.  However, I still get no accepted shares:

:loop

ccminer -a whirlpoolx -o stratum+tcp://stratum.nicehash.com:3343 -u bitcoinaddress.worker -p d=0.02

pause
goto loop

I used the above both with and without the difficulty parameter.  Soon as your new release is posted, I will try it.       --scryptr

AVX-512 CPUs are going to have software LUT3 on 32(!) 512-bit registers

There are some warnings when compiling. I will take a look later. Klaus_t has fixed intensity and double nounce reporting. This should improve the speed on the pool for low difficulty. I am checking the changes and merging them now.

brother. i confirm. i have the same issue with every source out there (linux version!).

I updated line 47 of x15/whirlpoolx.cu to be:
uint32_t throughput = pow(2,19);

That got rid of the memory error, but I've encountered another issue.  When I hash with both GPUs (both 750Ti) one GPU gives me a crazy hashing number, for example:
[2015-03-08 14:17:02] GPU #1: GeForce GTX 750 Ti, 667438585 kH/s
[2015-03-08 14:17:03] GPU #1: GeForce GTX 750 Ti, 661272871 kH/s
[2015-03-08 14:17:03] GPU #1: GeForce GTX 750 Ti, 658636297 kH/s
[2015-03-08 14:17:04] GPU #1: GeForce GTX 750 Ti, 657527143 kH/s
[2015-03-08 14:17:05] GPU #1: GeForce GTX 750 Ti, 658030840 kH/s
and fills up the screen very quickly with these values (I believe the other GPU at some point does output a valid looking hash, but it scrolls by so quickly).  But if I use the -d switch and hash with only one of the GPUs, I get proper values of:

That is really good. my 980 is around 300MHASH with overclocking. I tried to rewrite to uint4 but it went slower. What did you do? did you remove the lookuptables?

This is working on my 960 using my build(42) on windows 7

ccminer.exe -a whirlpoolx -u 1CTiNJyoUmbdMRACtteRWXhGqtSETYd6Vd -p 1 -o stratum+tcp://stratum.nicehash.com:3343

but you need to wait some seconds, and then Nicehash will set the diff correcly.

My 960 is also getting abit higher hashrate. I use -500Mzh on the memoryclockrate.

Thanks, SP_  --

I haven't been able to mine whirlpoolx on NiceHash yet.  Right now it is the hottest algo there.  

NiceHash posted that they increased the security for DDOS attacks, and miners are complaining that they are being blocked.  Earlier this week NiceHash was offline for maintenance.

I use a JSON.conf file as below:

{
   "url" : "stratum+tcp://stratum.nicehash.com:3343"
   "user" : "bitcoinaddress.worker",
   "pass" : "d=0.02",

   "algo" : "whirlpoolx"
}

and call it with the command line "ccminer.exe -c JSON.conf" on Win7 x64 with a GTX 960.  I get about 128150 kh/s but no accepts.       --scryptr

-a whirlpoolx

Thank you.  How do you properly call the algorithm?   Is it "whirl", or "whirlpoolx"?       --scryptr

-a whirlpoolx

try -p d=0.02 in the password

To fix the default intensity(linuxI) you have to change the hardcoded value 26U in the whirlpoolx.cuda file. I forgot to add support for the intensity parameter. Will do it later.

Guys, this kernal is very fast, very profitable and very free. Please donate some beers to the authors

WHIRLPOOL COMMANDLINE--

What is the proper commandline for whirlpoolx on NiceHash?  Also, what is the default Intensity?       --scryptr

Same here.  Dual 750Ti Ubuntu 14.04
