not -d which is the device num, -f (factor) made for dev purpose (to find shares faster but which are rejected). There is no advantages except on some badly coded pools.

Algos are not all set to 1 by default, that also allow us (dev) to find the right one when we implement a new algo.

Thank you.  I confused the JSON format "diff" for "-d" (device) commandline switch.  Instead, "diff" JSON is "-f" on the commandline.  I used "diff" last night as an experiment, setting ' "diff" : 0.1, ', to see if the rig would be more stable.  The pool gave me a very low reported hash rate in the morning.       --scryptr

will there be support for CUDA (with compute capability 2.1) ?

Lyra2re;
The way I interpret that is that there is nothing which forbid the algo from running on 2.1 device, however you'll need to strip off any reference to groestl (and x11 as well).
Current implementation of x11 can't run on 2.1 nor on 3.0 devices

should be ok on 3.0 but the binary is not made for 2.1 (i only added SM 2.1 support for one of the 2 problematic algos, from KBomba code)

lyra2 works on SM2.1 (tested on a GTX460), but you need to recompile it yourself

on  linux its in Makefile.am :
nvcc_ARCH = -gencode=arch=compute_20,code=\"sm_21,compute_20\"

on windows, its in Project settings (x86 Release target, CUDA C/C++ options, Code generation : compute_20,sm_21 )
Code:
[2015-02-10 17:45:23] 1 miner thread started, using 'lyra2' algorithm.

i had to underclock a bit... my GTX460 is fully broken, was 430/500 kH/s for lyra2 with a normal clock

The problem with compute 2.1 compability is the algorithms who use the __SHFL instruction.

For x11 compabillity (killer) Groestl and simd needs to be rewritten, and then alot of the speed increase is gone.

when mining with x11 it works but user not shown in the pool site

when mining with lyra2re it works first after sometime nvidia gives error it escapes from error and hashrate is being 1054223
