DAG content differs

[Nreif]

Hi,

I have the problem that the Python Program provided here delivers other DAG contents and sizes than the DAG generator in geth.exe, Version 1.8.20.

Here some examples:

Results from Program Results from geth.exe presented here: Version 1.8.20:

DAG of 5. Epoch:

Size (from get_full_size): Real File Size: 1115684224 1115684232

First Bytes:

DF C3 CB A7 FE CA DD BA 9D 1E ED 6D AD DE E1 FE 46 54 EF 22 74 63 03 FB 78 64 B7 2E EC 5B C5 50 99 E3 FF F8 12 62 CA 45 BF 1A C8 A0 96 33 08 F7 76 CA 1C 24 C6 B7 5C 3B 2C B5 D9 F4 E8 67 E4 80 12 C7 CA DD C8 9C E1 9C 14 4A BD E8 59 6E 0B 22 18 D3 13 B4 B1 E2 E3 13 E7 4B 39 3C 56 CF 8A A8

DAG of 73. Epoch:

Size (from get_full_size): Real File Size: 1686109312 1686109320

DAG of 180. Epoch:

Size (from get_full_size): Real File Size: 2583686528 2583686536

Has anybody an idea for the reason of these differences??

Sorry, but the tool destroyed the formatting of my last post. Here is the content how it was planned to look like:

Hey @Nreif could you be a little clearer? Which Python application?

Hey,

could you please tell me the code to collect dag into file.

i m using below code but getting attribute error,

============================ import pyethash

with open("cache","rb") as fcache: cache = fcache.read()

data_size = pyethash.get_full_size(0)

print("Generating dataset (DAG) of size %d." % data_size) dataset = pyethash.calc_dataset_bytes(data_size, cache)

with open("dataset","w+b") as fcache: fcache.write(dataset)

============================================================== AttributeError: module 'pyethash' has no attribute 'get_full_size'
