The best way to make brute force AES, through Python?

Greetings, great and not so, the minds of Habra. To thebrotherkite value is encrypted in AES 256. Presumably, the key may be the MD5 hash of 5 characters(Latin alphabet in both upper and lower case, numbers from 0 to 9 and special characters _-+=). Tried myself to write bruteforcer, in Python(I Know, not the fastest, but th...

Is it possible to use multiple graphics cards for acceleration of scientific computing in the languages C++ or Python?

At the moment I'm doing scientific calculations (think of the matrix, which is good parallelise). If initially all began with sequential calculations on the CPU in python, pretty soon came the idea of parallelization on the CPU, and then CUDA (using a library numba in python). And the results are very good. However, it got ...

It is advantageous if the calculation of photogrammetry graphics cards for mining?

Having tasks that need to be considered on the cards. Wanted to know if the card is sharpened for mining, no video outputs (these were from nvidia, it seems) for such things. Maybe someone was testing on similar computational processes? Or can anyone have access to such computing systems to test yourself :)

Video card P104-100 can not be used for mining?

Now popular cards on Yandex market P104-100 1607Mhz PCI-E 1.1 4096Mb, this card is issued specifically for mining, do they still buying miners? I figured on the maps and Bang! (I'm not a miner). Now collect the server, and the programmer is asked to supply graphics accelerator with CUDA for some work with the acceleration d...

How best to maximize a discrete function?

There is a function f = (a, b, c, ... ) where as arguments a, b, c can be passed values that change from k to n (different for each a,b,c) 1) you need to get the values of a, b, c in which f - maximum 2) you need to get the combination of the intervals a,b,c at which f is not below the threshold fMin A conventional CPU b...

The truth is that OMP inhibits CUDA?

In General the problem is. There is a banal code**** double time = MPI_Wtime(); cudaMemcpy(*****) cout << "time =" << MPI_Wtime() - time << endl; Nvcc compile with mpicxx -fopenmp Set the variable OMP_NUM_THREADS = 1 Measured the time. Next, Set the variable OMP_NUM_THREADS = 2 Measured the time, it was w...
