there have been some updates to the github repo today.

The only remaining problem I find with the current state of the github repo is that the 64 bit compilation on 64bit Linux machines does not appear to produce working code. I get runtime errors about "thread <ID> create failed."

So the only way to get it working is to cross-compile for 32bit like this

./configure --build=i686-pc-linux-gnu "CFLAGS=-m32 -O3" "CXXFLAGS=-m32 -O3" "LDFLAGS=-m32" --with-cuda=/usr/local/cuda-5.0

(i386 dependencies required, such as g++-multilib, ia32-libs, libcurl4-openssl-dev:i386)

Can't download the source from Mega: it just stays at 0% with "Starting download". Are there any other mirrors?

Anyone? I need to download and compile it on Windows. Tried both FireFox and IE and Mega would not start download in either.

Thank you.

EDIT: Build problems. Building on cygwin:

$ ./autogen.sh
configure.ac:116: error: possibly undefined macro: AC_MSG_ERROR
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

This one runs ok:
$ ./autogen.sh m4_pattern_allow

$ ./configure
gives:
......
checking for json_loads in -ljansson... no
checking for pthread_create in -lpthread... yes
./configure: line 6032: syntax error near unexpected token `,'
./configure: line 6032: `LIBCURL_CHECK_CONFIG(, 7.15.2, ,'

Before that I've successfully run ./configure && make && make install on curl-7.29.0


Now, deleted all files an started afresh without running autogen.sh.

./configure finished fine, but the new hiccup is in make:


EDIT: Seems I didn't have nVidia GPU Computing Tooltik installed. It should have been linked to from OP
https://developer.nvidia.com/cuda-downloads?sid=311699

Still compile problems, though:
Code:
nvcc -g -O2 -arch=compute_10 --maxrregcount=124 --ptxas-options=-v -I./compat/jansson -o salsa_kernel.o -c salsa_kernel.cu
nvcc : fatal error : Cannot find compiler 'cl.exe' in PATH
Makefile:922: recipe for target `salsa_kernel.o' failed
make[2]: *** [salsa_kernel.o] Error 127
make[2]: Leaving directory `/d/CudaMiner-master'
[/s]

EDIT: this is getting tedious. I've added path to cl.exe
Luckily I still had Visual Studio 2008 installed as cl.exe from VS2012 was not accepted. Now to the next hurdle:

Code:
nvcc -g -O2 -arch=compute_10 --maxrregcount=124 --ptxas-options=-v -I./compat/jansson -o salsa_kernel.o -c salsa_kernel.cu
salsa_kernel.cu
salsa_kernel.cu(16) : fatal error C1083: Cannot open include file: 'sys/time.h': No such file or directory
Makefile:922: recipe for target `salsa_kernel.o' failed
make[2]: *** [salsa_kernel.o] Error 2
make[2]: Leaving directory `/d/CudaMiner-master'
Makefile:472: recipe for target `all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/d/CudaMiner-master'
Makefile:276: recipe for target `all' failed
make: *** [all] Error 2


Still asking: Any alternative venues for building this on Windows? Maybe there are precompiled binaries, the way pooler distributes his cpuminer for Windows?

Also, could you provide Windows compile instructions in either OP or in README.txt?!

great benchmark number, yet it commes nowhere near when it commes to actual running. How why what and when happend, i no longer get result does not validate as with the previous version but alltogether it is

WAAY slower then the 17/04/2013 version.

NUTS, it used to be around 165 kh/sec. now it just promisses more to return less. i'm boggled.

Nemo1024, cygwin build problems will be mostly caused my choice of using #if WIN32 to decide whether to use Microsoft Visual C++ specific features and compatibility headers from the "compat" folder. Try replacing it with a preprocessor macro that identifies a Visual C++ version.

Also note that nVidia doesn't support gcc as a backend for the nvcc compiler in Windows. This would be the showstopper.

I recommend Visual C++ 2010 Express for the job.

crunchy, that's puzzling because the CUDA code hasn't changed a single bit.

For speed comparisons, try to give the same launch parameter that was chosen in the 04-30 version.
Is also the -i flag the same as back then?

those running cudaMiner on linux systems equipped with nVidia Optimus need to install bumblebee (or comparable software packages) and run

optirun cudaminer

instead of just

cudaminer

Or depending on the software package used to select the GPU, some other program may be required (not optirun, but e.g. primusrun)

I am working towards a more modular design of the CUDA code now.
I will support kernels of these types:

L: legacy devices (compute 1.x)   (I've removed that one in late April, now it's back).
F: Fermi class devices (compute 2.x)
K/S: Kepler class devices with compute 3.0
T: Titan devices and other Kepler based devices with compute 3.5 (even a cheap GT640 might qualify)

Autotune always tunes the kernel matching the graphics card, but I will allow a manual override

Some work in progress is already in my cpuminer fork repo on github (check the cbuchner1 account).

cbuchner1, I stopped trying to build as I finally managed to download your pre-built archive from Mega.co.nz after trying 5 different machines what felt like 500 times. Could you release the prebuilt archive on some other file sharing service?

Now, some results:

Run on laptop with Quaddro FX 880M. Really nice. I can't compare to CgMiner as it always crashed on all my nVidia cards, but for comparison, poclbm doing SHA-256 managed to give max 12MHs on the same card:

A small bug report. I added -t 8 argument just for fun and got the followign. Maybe better error handling is in order?

ANY kind of error handling is in order.

Playing around with core and memory clock settings individually, I see that memory clock plays the most important role.
--texture-cache setting did not affect performance.
--interactive 0 gave me additional 10kh/s


I ended up using 1012/880/2350

I have tried out CudaMiner with my GUI front-end, Crypto Miners in Tray, and it is fully compatible.

Christian, I am sending 1 LTC your way as a thank-you token.
