It's possible to reduce data size?..

[Saikatsaha1996]

No solution available?

@CryptoGraphics how to reduce VTC data buffer size ?.. mey be need to some modifications for work.. can you tell me please..

Total OpenCL global memory 3.5 GB maximum allocated memory 900MB

Which codes need to be edite ? Can you please help ?

[Saikatsaha1996]

@CryptoGraphics mey be i should change value in this file.. but actually i don't know anything about coding if you help me it's really very much helpful for me thank you

https://github.com/CryptoGraphics/VerthashMiner/blob/main/src/vhCore/Verthash.cpp

[sylvesternumski]

Are you setting the following environment vars prior to launching? export GPU_FORCE_64BIT_PTR=1 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export GPU_SINGLE_ALLOC_PERCENT=100 export GPU_MAX_HEAP_SIZE=100

Already tried...@sylvesternumski

#!/bin/sh
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_USE_SYNC_OBJECTS=1
export GPU_SINGLE_ALLOC_PERCENT=100
export GPU_MAX_ALLOC_PERCENT=100
export GPU_MAX_SINGLE_ALLOC_PERCENT=100
export GPU_ENABLE_LARGE_ALLOCATION=100
export GPU_MAX_WORKGROUP_SIZE=1024

But not working because memory available only 900MB for max allocation Total 3.9GB memory

[Saikatsaha1996]

@sylvesternumski can you teach me about how can I change VTC data buffer size by code ? Mey be need to change in this .cpp file for data buffer size.. https://github.com/CryptoGraphics/VerthashMiner/blob/main/src/vhCore/Verthash.cpp

[sylvesternumski]

The data buffer might be limited by hardware. What card are you trying to run this on? In order to support the verthash algorithm, you need at least 2GB dedicated ram on the card itself.

[Saikatsaha1996]

@sylvesternumski Actually it is android device with full OpenCL 2.0 support, gcn 1.0 comfortable Actually only memory requirment not matching..

That's why I am asking for help.. just wanted to reduce memory size ..

It is experimental .. so if i am getting help i would be very helpful for me..

[sylvesternumski]

Memory requirements are the most import part, the size of the verthash dat file cannot be modified, this is one part of the algorithm that makes it ASIC resistant. You might be able to modify the code to use a file instead but then your hashrate would be severely diminished.

[Saikatsaha1996]

@sylvesternumski I don't need performance.. i don't need anything.. i am doing it only for experimental purpose only..

Can you help me for reduce verthash dat file ?.. I just want to use..

[sylvesternumski]

You cannot reduce the verthash dat file size. If you really want it to be usable on other platforms, you can attempt to convert the miner to use a file instead of ram, the p2pool and other pools do this for confirming share submissions. I haven't really looked into the code beyond building it as is.

@sylvesternumski How can I do this for verthash dat useing ram ?

Memory requirment solved but new error.. Help!

kernels/sha3_512_precompute.cl is part of a directory in the distribution that needs to be in the directory you're running the miner. It's the opencl routines that are run on the card to perform the mining.

Android GPU mining 😂🤣 But thank you so much for your fast to last time help

[sylvesternumski]

That's just slightly faster than I can hash by hand. Nice, put it into a wallet and have it hash in the background. Might be interesting but my guess is it'll eat the battery. (Maybe only hash when plugged in?)

Battery temp 38°C Total watt 1.3 Watts

[sylvesternumski]

Back of the napkin calc tells me that ain't too bad for khash/watt. Is the 1.3 just the gpu?

Sir i know.. actually i am not professional miner.. And it is not for profit.. just for fun only.. My pc given me 450 kh/s with 55watts only.. I just like test with android GPU capabilities.. I am not mining now.. just testing with android GPU.. 🙈

12 hrs reward results with 8.85 kh/s Max temperature 35 to 39°C after 12 hrs
