Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
I see people asking for pool fallback a bunch... Maybe someone else will find this useful. *shrug* 
In English: Mine on hashbros until there's a connection issue. At that point, switch to middlecoin for an hour. Repeat ad nauseam.
Code:
#!/usr/bin/env bash
pools=(
"--url=stratum+tcp://mine.Hashbros.co.in:3333 --userpass=worker.name:x --retries=3 --algo=scrypt -l Y7x32 -C 1 -i 0 -m 0 -H 1"
"--url=stratum+tcp://middlecoin.com:3333 --userpass=15wcm1ZxixUjjq3tKEoKT55qLttoCN2TBY:x --retries=3 --time-limit=3600 --algo=scrypt -l Y7x32 -C 1 -i 0 -m 0 -H 1"
)
while true; do
for i in $(seq 0 $((${#pools[*]} - 1))); do
./cudaminer ${pools[$i]}
echo "Restarting in 3... CTRL-C to stop."; sleep 3
done
done

Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Yes so it could perhaps shut off the miner and launch itself again with the new nfactor
cudaminer terminating is enough- get your batch/bash script to restart it:
Code:
#!/usr/bin/env bash
while true; do
./cudaminer --algo=whatever --url=whatever --userpass=username:password -l Y7x32 -C 1 -i 0 -m 0 -H 1
echo "Restarting in 3..."; sleep 3
done
while true; do
./cudaminer --algo=whatever --url=whatever --userpass=username:password -l Y7x32 -C 1 -i 0 -m 0 -H 1
echo "Restarting in 3..."; sleep 3
done
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Hi-ya Christian,
My 660Ti registers at ~270 khash/s peak (scrypt) for a single instance of cudaminer (which appears to start a single mining thread) - By starting two instances, I'd have expected that rate to halve. Instead, each instance reports ~200khash/s peak.

This is surprising. What is your launch configuration?
What does GPU-z show for GPU utilization when running just a single instance?
How's GPU utilization and memory usage with 1 and 2 instances?
I used the the same launch config (-l K7x32 -C 1 -i 0 -m 0 -H 1 a product of not realizing it was already running in another terminal). After messing around with it for the last day, I can tell you the reported numbers on the second cudaminer instance are lies.
Juggling the launch config around (7x32, and the other at 7x14), I can get two instances to submit results correctly, but they don't exceed my 270 khash/s (one settles at 180 something khash/s and the other at 80 something). There's a +500MiB GPU memory usage increase in this scenario (Don't know about utilisation... nvidia-smi won't report it). There doesn't appear to be any operational efficiency to gain here.
Apologies for wasting your time.

Is there any efficiency to be gained by running multiple instances of cudaminer on the same card? Or, am I reading these figures wrong?

The github version adds maybe 10 or 15 kHash/s more (by supporting the -C 1 flag). It will be in the next cudaminer release, toggether with scrypt-jane (Yacoin) mining support.
git pull and build the latest (with all the latest scrypt-jane h4x), I get 10khash/s less than if I git reset --hard 744d7b7923e106fadfc20eff9833d5d7a5da93c8 (December 28th) on scrypt, on my 660ti.
Does anyone else see this?
Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux]
Kinda curious their what your getting with your 660ti on its stock speed their cbuchner1 I get about 250khash/s off the start then it drops to maybe 247khash/s. Im using the 12-18 version. Would I see a decent improvement compiling off the github? And whats a stock gtx 460 get roughly for hash rate?
It's worth building the github version- I got a decent improvement.
Gigabyte 660ti (GV-N66TOC-2GD) went from ~250 khash/s, to somewhere between 262-270khash/s. I'm using the switches -l K7x32 -C 1 -i 0 -m 0 -H 1
Not sure how the 8 khash/s variance comes about (Linux, fresh boot, with nothing open but X and a terminal). Maybe it's solar flares?
Does lorem ipsum work?
You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... and only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.
