given up on NV cards and are move one ATI card into most boxes

Have hit the sweet stop with one 290x running @ 4.5m p/sec doing 4 threads in under 10 minutes. that's 24 per hour.
those other ATI cards generally are running over 2.1m to 3.1m p/sec and are doing 8 threads per 20 mins same 24 per hour.

NV cards may work hard but none of them can get within that sort of output
24 per hr.


I don't want to get into an ATI v NV war here...

With my NV-Titan, I can get 1 per 35secs, which equates to about 100/hr.

Unfortunately my cpu died. So the titan is off wwwwcl as I can't drive it to 100% with the cpu I currently have.

As for selecting the optimal settings in wwww.ini. I just found settings that sent my GPU to 95-97% and thought "good enough".

I found that I needed all 6 "real" cores of my i7-3930k to drive my titan 100% with wwwwcl. I assume the program is cpu/gpu hybrid. It seem you need enough cpu resources to drive the gpu to high usage.

Also I ran 2x instances to cater for the drop when the code stops to get more work.

I also found that this setting needs to be set >= number of cores.:

My guess is the parent executable (prpclient) calls wwwwcl and uses 1000. On linux with the ps command you can see this option being set:

[ec2-user@ip-172-31-13-232 prpclient-4]$ ps -aef | grep www[w]cl ec2-user 32248 31644 98 12:47 ? 00:02:43 ./wwwwcl -TWieferich -s1000 -p370229200000000000 -P370229300000000000 ec2-user 32259 31512 97 12:47 ? 00:02:35 ./wwwwcl -TWieferich -s1000 -p370229900000000000 -P370230000000000000

Package name:

$ file genefer genefer: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.24, BuildID[sha1]=f354c4949715c4f31d944e4fd236f9170fc01650, not stripped

Looks like 'genefer' is the 64bit build.

All lines beginning with "gen":

$ grep ^/*gen prpclient.ini geneferexe=./geneferocl //geneferexe=./genefercuda geneferexe=./genefer

Aaah, that makes sense. Whoopsie.

I had this in prpclient.ini:

geneferexe=./geneferocl //geneferexe=./genefercuda //geneferexe=./genefer

It's now:

geneferexe=./geneferocl //geneferexe=./genefercuda geneferexe=./genefer

Lets see how it goes. In the linux 5.3.1 distribution it didn't have genefer64.

I'm using the g2.2xlarge nodes on Amazon's EC2.

I'm winding down. I did have a number of them, but since they started to all error out to cpu now, I've dropped them all off.

But I have 1x VM remaining, with 3x instances running. The VM is effectively 4x cores (x2 for hyperthreading). Total of 8 cores as seen by the OS.

Top excerpt:

top - 22:36:38 up 22 days, 10:32, 1 user, load average: 3.00, 3.00, 3.04 Tasks: 106 total, 4 running, 102 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 5.8%sy, 87.8%ni, 6.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 15404752k total, 803500k used, 14601252k free, 143420k buffers Swap: 0k total, 0k used, 0k free, 194596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17765 ec2-user 39 19 124m 95m 1164 R 100.0 0.6 9466:02 pfgw64 15689 ec2-user 39 19 124m 95m 1168 R 99.5 0.6 10632:48 pfgw64 16098 ec2-user 39 19 124m 95m 1176 R 99.5 0.6 10408:43 pfgw64 1 root 20 0 19488 1600 1288 S 0.0 0.0 0:02.04 init

Even only 3x cores are used, I left it over night and it's still going (at a rate roughly 1/wk).

If I could ask, that the time allowed to complete be increased on this?

If my gpu can complete it, the task gets done in a few hours.

But if it drops to CPU, it takes a little over a week and then the work becomes redundant.

Thanks I've installed them.

But I'm getting this error:

$ ./prpclient
Could not determine version of PFGW being used. Missing version data

Running pfgw on its own I get:

$ ./pfgw64 -V
PFGW Version [GWNUM 27.11]

Error opening file helper.txt

Any ideas?

I'm having trouble connecting to for the last 8hrs+ or so. I'm after the latest prpnet binaries to install on a new box.

Is this site coming back soon? Or is there a active mirror?
