@cayoenrique

Not upset at all, I think that you are doing some great work on this subject and I wish you success.
If it would help you to have a faster more modern GPU then we could put together a small crowd funding page and perhaps see if it was practical to post a GPU to you or for you to source one locally.

To the best of my knowledge, your topics recently have been the first for possibly over 10 years to release a new biss BF tool into the public domain.
Nowadays with the correct home/enthusiast PC equipment and CudaBISS, it is practical and possible to BF a biss CW in time to make it useful for a feed, ie, before the feed has ended.
If your OpenCL project progresses to the same level or beyond then it could provide a very useful tool for BF.
The added advantage of your OpenCL tool if I understand correctly is that it can be used for both AMD and NVIDIA GPU, this is a big bonus point.

One question, is it possible to run multiple instances of your OpenCL tool on the same PC at the same time and to nominate which GPU in the PC is used per instance?
With CudaBISS it is possible to use commmand lines to instruct CudaBISS which GPU to use in a multi GPU setup.

I got this error too, it goes away if you lower the Global threads value.
It works with 16128 , with 16384 it gives that error, I did not try values in between.

@moonbase
See OCLBiss.cfg to select the device, even though I'm not sure what P(latform) encodes... but I have only one 4090 card, maybe it is possible to use also the integrated Intel graphics...

#DEFINITIONS
#DETECTDEVICEENABLE:1 #0=disable 1=enable
#SELECTEDDEVICE: a two digit number "PD" where P is selected Platform and D is selected device. Please note that D nor P can be bigger that 9.
# Please enable for once DETECTDEVICE:1 to detect your platform and devices. And make a note of the desire device.

you could always record encrypted TS and decrypt later

@azboxgo
He is already doing all you said:

Code:

Connected Device:                                       NVIDIA GeForce RTX 4090
***
PROGRAM_FILE selected:                                  csa_decrypt_1block_004.cl
***
Number Loops per thread:                                8192
***
Local threads:                                          256
Global threads:                                         1536

Yes you can use Intel internal GPU if available. Never done it but I guess If you have a AMD APU it should show also as an alternative.

Just start with @azboxgo example he seems to have a 4090 and once it goes over the limit then change to bigger numbers.

Code:

Number Loops per thread: 8000
Local threads: 256
Global threads: 16128

To the best of my knowledge, your topics recently have been the first for possibly over 10 years to release a new biss BF tool into the public domain.

It is funny, for almost same years I have offered to create Opencl thread but no one was interested. To be honest I have a few SU old timers users that kept bulling me here. So for most of the time I kept my self on the background.

The added advantage of your OpenCL tool if I understand correctly is that it can be used for both AMD and NVIDIA GPU, this is a big bonus point.

Yes

One question, is it possible to run multiple instances of your OpenCL tool on the same PC at the same time and to nominate which GPU in the PC is used per instance?

Here is where its get trick. The short answer is Yes. Just copy OCLBiss.exe + OCLBiss.cfg + the *.cl that you use in a folder. Make copies of that folder and change the config to do different start points. Same GPU or different.

Now A program like the 014 where it does not uses memory to share and intermediate value between kernels, my best guess is that it should be find. Problem comes if you do share Global memory like in 021. There was no waranties that thememories are kept reserve by each instance. So one instance of the program may be overriding memories used by the other!!

Even when I have played with OpenCL for years, it does not provide me with enough experience. As I only played with version 1.2 general features. The Official answer was to avoid multiple Instances. There is no warranty that devices do actually separate resources!! Now with OpenCl versions over 2, most likely 3.0 and with new GPU it seems to be OK. As they where build to share.

Now there are users in the net, that claims it is perfectly find!
For example you can use Opencl and the render of your screen does not get affected, if you keep your kernels under certain time. That was what the claim.
You gave the sample of Cudabiss with multiple instances.
Maybe was a problem with AMD GPU! I do not know.

With CudaBISS it is possible to use command lines to instruct CudaBISS ....

I am glad you ask again. I did posted an answer, that again got some how lost. I have a feeling have something to do with my mouse button failing.

I have no experience with cudabis. Never read a tutorial. So I do not know how it works.
My answer was that if you had use Cuddabis in multi-thread faction, meaning different instances, and it works for you, that is fine. In particular that if you find the key always then that proves it does work. Or even if you find the key half of the time, I guess it is a valid used of time and energy. That what I ask you guys to ask the original developer.

Now you are saying it is not multiple instances, but in fact a normal setting. This change my answer, because the developer was on purpose building such features. So the Cook/Generals story do not apply.

... to instruct CudaBISS which GPU to use in a multi GPU setup.

I have not built such features. We could in the future. But different GPU can be set as I explain with copies of the folder, with different settings for each different GPU. So the answer can do it manually.

For those that may still have problems correcting the last issues. Here more or less same file without the errors.
And I saw some weird timenig in windows. So I change the timer function to match Linux. Now the kps are more stable. It has nothing to do with functions but time was unreliable.

But for you it does work 10 NVIDIA Corporation GeForce 820M GPU for OCLBiss.exe 014M Right?

cayoenrique · Sep 20, 2023

There are limits at what we can do on old GPU using Opencl 1.0.
ModprogramsOCLV100.zip (63.49 KB)

https://workupload.com/file/wJDcPYLuAKf

Here 012 & 0014 build for Opencl 1.0,
Now I could not make work
csa_decrypt_1block_002.cl
csa_decrypt_1block_003.cl

In my very old GPU, The cl compilation just hang up to never end. There is no error that I can try to solve. Sorry.

dvlajkovic · Sep 20, 2023

Don't quite understand if it's meant to work, but on my GPU
OCLBiss_014M_modOCLV100
runs without errors.

my setup is
LOCALTHREADS:256
GLOBALTHREADS:65536
LOOPSPERTHREAD:8000

I've tried:
PROGRAM_FILE:"csa_decrypt_1block_000.cl"
PROGRAM_FILE:"csa_decrypt_1block_001.cl"
#PROGRAM_FILE:"csa_decrypt_1block_002.cl"
#PROGRAM_FILE:"csa_decrypt_1block_003.cl"

and then:

#PROGRAM_FILE:"csa_decrypt_1block_001.cl"
PROGRAM_FILE:"csa_decrypt_1block_002.cl"

Both give nice kps.

Explanation of _modOCLV100
OCLBiss_014M_modOCLV100 was build mainly for @Me2019H. He was the one that ask me to return the learning tutorials.
Sadly he has no Discrete GPU. Only old Nvidia 96 and Intel 160 cores Gpu. Been old means that It can only handle OpenCl API version 1.0. ( 100).

He has been behind because has been some trouble to setup his GPU.

Now that they work, he is finding that OLD API 1.0 has its limits. So He can ONLY execute "csa_decrypt_1block_000.cl" & "csa_decrypt_1block_001.cl" NONE of the csadvb lib cl kernels.

=========================================
I bet you find out that 021 split kernels where the fastest. But they consume too much memory. That is the reason why big kernels are rejected, the memory requirement is over what you have.

To your disappointment, my next step will be NOT using Split Kernels. But I will be using GLOBAL memory. Instead of bringing the back the results of all those FAKE keys. I plan to save them in Global memory.
@C0der brought us the fact that we should get 1 FAKE key every 2^24 keys tested, more or less ( 1/ 16777216). So we save those Fake keys, when we have enough FAKE keys then we launch a Second Kernel with a different SB ( second TS ) to reduce the number or fake to almost 0. Then we read the last remaining surviving FAKE keys. CUDABISS seems to suggest it does this 3 times to get the final GOO Key.

Well the problem at the moment with _modOCLV100 is that they can not setup buffers with CL_MEM_HOST_NO_ACCESS. So lets see what we can do for @Me2019H

It was hard but finally found a way for @Me2019H to be able to execute 021.
As simple that can be just removing "CL_MEM_HOST_NO_ACCESS" from the code is enough to allow device use of internal memory.
And the hung-up can be override by disabling compiler optimization. cl-opt-disable

OCLBiss_021_modOCLV100_000.zip (38.12 KB)

Code:

https://workupload.com/file/sVNSALuEVGa

same pass www.sat-universe.com
Listen I have a filling that my compilation failed because my GPU has o little memory, Just try as is. the go to line OCLBiss.c line 283 and excahnge those lines.

Code:

//    err = clBuildProgram(program, 0, NULL, NULL, NULL, NULL);
    err = clBuildProgram(program, 0, NULL, "-cl-opt-disable", NULL, NULL);

By uncommenting 1rst and commenting second. You will enable optimization. Hope it works for you.

Thank YOU
I'm grateful for all that you do and I appreciate your time.

it works

Your welcome.

I did changes so you do not fall behind. But in my laptop that "clBuildProgram(program, 0, NULL, "-cl-opt-disable", NULL, NULL);" speed is very bad.

Now that you can execute more or less all I posted, you should recalled that I said:
Intel HD Graphics 4400

Render Config
Shading Units 160
TMUs 20
ROPs 2
Execution Units 20
Theoretical Performance
Pixel Rate 2.300 GPixel/s
Texture Rate 23.00 GTexel/s
FP32 (float) 368.0 GFLOPS
FP64 (double) 92.00 GFLOPS (1:4)

Dell GeForce 820M 2 GB

Render Config
Shading Units 96
TMUs 16
ROPs 8
SM Count 2
L1 Cache 64 KB (per SM)
L2 Cache 128 KB
Theoretical Performance
Pixel Rate 2.500 GPixel/s
Texture Rate 10.00 GTexel/s
FP32 (float) 240.0 GFLOPS
FP64 (double) 20.00 GFLOPS (1:12)

This Shading Units used in screen graphics are in fact the cores. You have more cores that the discrete GPU. I suspect that if you Google your Laptop by model, your original CPU was not an i5. Bu a less powerful CPU.

I hope you install your newest GPU Driver from DELL. Once install there should be a menu by Nvidia. Usually in the lower left side of toolbar. In some Win7 PC you can also right click on desktop and you can get Nvidia preference.
Well in that Nvidia Graphics Setup you should find an option to setup witch GPU should be your default. You need to select Nvidia GPU.

At this point you should have find witch is you faster OCLBISS program and witch what GPU is the fastest. Intell having 64 more cores should be the winner I suspect.

What we trying to do is to assigned Nvidia to be the Win7 default Graphic Render. Why? so that Intel HD4400 gets free from rendering. So it is not only the fastest but also Is free for you to use. No more window black screen if you assign too much work. And you GPU gets to be even faster in Opencl. See the point. Then after the change. Check the speed it should be quicker. Another advantage is that I belive HD4400 is Opencl API V1.1. I suspect you will not need for -cl-opt-disable.
So once you change your Win7 GPU also try to run same OCLBiss_021_modOCLV100_000. Then go to OCLBiss.c line 283 and reverse the commets.

err = clBuildProgram(program, 0, NULL, NULL, NULL, NULL);
// err = clBuildProgram(program, 0, NULL, "-cl-opt-disable", NULL, NULL);

And this time you should find out you no longer need cl-opt-disable and the program is at least 10X faster.

Finally. I never done this but it should be tru. Your HD4400 Global memory is in fact you PC RAM. This is interesting as your opencl data buffers do not have to pass thru PCI Express read/write! You should be able write INITs or Read results much faster changing operations to MAP. In MAP the same variable that exist inside GPU also can exist in PC C main program, ( Shared Memory). So no wait time in PCI Express operations. You program will get a littel faster. Once you have your Nvidia drive as default latter I can show you. 1rst do Win7 default change, and tell us the result.

@all
This week I been busy with personal issues. I hope to have time today and the following days. As I said I intent to launch multiple kernels so that there is always work in the queue. This technique I suspect will render useless the need for launching different programs at same time. Just as yo do in CUDABISS.

cayoenrique · Sep 23, 2023

Update. Be sure I been working on the program. Just that you understand. I am no professional C programmer. In fact I code rather slow as I even my typing speed is slow and I make a lot of type errors.

Now introducing multithreads is confuse topic itself. After giving some thought I realize that the future program may get confuse for a newbie. So i am changing the general structure of our program. I know I told you guys that we can write our code between the lines I posted in the program. Instead I am placing the OpenCl, and thread outside in their own C file. The idea is to let in Main ONLY the logic for the program it self. At the end a newbie should be able to follow what the program does more easily. This change had taken ma day and I guess I need at least one more.

If you are trying to understand the code and want to learn PLEASE post you questions so that I know that there are more people trying to learn to code. At the moment I know @dvlajkovic, @Me2019H & @azboxgo are trying to understand the C code logic.
