kandi X-RAY | gmac Summary

gmac is a C++ library typically used in Hardware, GPU applications. gmac has no bugs, it has no vulnerabilities and it has low support. However gmac has a Non-SPDX License. You can download it from GitHub.

Reduce the complexity of your code. GMAC transparently takes care of the consistency and coherency of the data both used in the CPU and in the GPU, so your code gets simpler and cleaner. This means that you only have to use a pointer per allocation to access data both in the CPU and the GPU.

Check with ethtool -h which command is responsible for the respective action
Check in ethtool source code how command is handled
Check in net/ethtool/ on the kernel side

And a general hint: Basically no network driver implements all ethtool functionalities.

How can I compute number of FLOPs and Params for 1-d CNN? Use pytorch platform

Asked 2020-Oct-21 at 08:23

My network is a 1d CNN, I want to compute the number of FLOPs and params. I used public method 'flops_counter', but I am not sure the size of the input. When I run it with size(128,1,50), I get error 'Expected 3-dimensional input for 3-dimensional weight [128, 1, 50], but got 4-dimensional input of size [1, 128, 1, 50] instead'. When I run it with size(128,50), I get error 'RuntimeError: Given groups=1, weight of size [128, 1, 50], expected input[1, 128, 50] to have 1 channels, but got 128 channels instead'.

Here is working code using the ptflops package. You need to take care of the length of your input sequence. The pytorch doc for Conv1d reads: ,

which lets you backtrace the input size you need from the first fully connected layer (see my comments in the model definition).

Unable to build Botan for Android on Windows

Asked 2020-Mar-21 at 22:13

I cannot understand how to build Botan for android, according on the instruction here:

$ export CXX=/opt/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android28-clang++

$ ./configure.py --os=android --cc=clang --cpu=arm64

i cannot understand how to use this commands on Windows, also reading previous issues did not help me, can you tell me how did you build this library on windows step-by-step, just your command examples?

I used --cc-bin option of configure.py to specify the path to the compiler, it is considered a solution for windows, but what i have is:

It seems Botan support for building Android binaries on Windows hosts is limited. You will have to use dark magic to make this work.

The build process consists of two phases, the configuration phase and the make phase.

The Android-specific instructions in the documentation you linked do not cover the whole build process, only the configuration phase. For the make phase, you then have to follow the Windows-specific instructions (link).

Configuration phase:

You will need the following binaries, adjust the paths to your machine:

clang++ (note the .cmd at the end): C:\Development\android-ndk-r19c-windows-x86_64\android-ndk-r19c\toolchains\llvm\prebuilt\windows-x86_64\bin\armv7a-linux-androideabi28-clang++.cmd
ar: C:\Development\android-ndk-r19c-windows-x86_64\android-ndk-r19c\toolchains\llvm\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ar.exe

In the Botan folder, run the configure command:

It seems that the error was in the directory, which did not exist C: \ Program Files (x86) \ Windows Kits \ 10 \ include \ 10.0.18362.0 \ ucrt;

I uninstalled the other Windows Kits to solve the problem. And it was already possible to compile Botan.

How to verify a GMAC?

Asked 2018-Jan-31 at 21:50

According to section 5.2 (Two GCM Functions) of the Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC, it mentions that for the case of GMAC, the authenticated encryption and decryption functions become the functions for generating and verifying an authentication tag on the non-confidential data.

Looking online and on the JCA reference page, I understand that GMAC is generated like this:

...

ANSWER

Answered 2018-Jan-31 at 21:50

Yes, that is correct. The Java API verifies the MAC, throwing an exception if it fails. It returns the encrypted plaintext message, but in your case the message is empty.

There are two design choices for creating a GCM API: handle the authentication tag separately or assume it is part of the ciphertext. Although I prefer the separate handling of ciphertext and authentication tag, Java/Oracle decided to keep to the AEAD RFC and include the authentication tag with the ciphertext (requiring extra buffering, a code size increase of about 30% and removing the posiblity to perform online decryption).

So although your code maybe feels a bit strange the handing of the MAC seems OK - if it weren't you'd get a AEADBadTagException in the call to doFinal during decryption.

Using a static key and IV certainly isn't OK, but I presume those were used for testing purposes - right?

This has been fixed in newer Node versions (>=6.3). Here's the relevant GitHub thread and PR: https://github.com/nodejs/node/pull/6376

It seems the developers just implemented the recommended default value before tackling arbitrary lengths.
