A project imulating the evolution of a nxn ising model through k steps, using CUDA. Made for Parallel and Distributed Systems course, ECE AUTH, 2022.

First, download/clone the repository, and navigate to its directory.
Open the CMD and cd to the repos' directory. Compile using
make -f MakeFile
and run using
ising
You can use up to two command line arguments. If one argument is provided, it specifies the matrix width n, while if two arguments are provided, the first specifies n, while the second specifies the number of steps k to iterate for.
If no arguments are provided, the variables are defaulted to
n = 5000, k = 10.
Eg running for n = 4000, k = 5:
make -f MakeFile
ising 4000 5
If you don't have make (or a problem occured when using the MakeFile), use this line to compile:
nvcc -rdc=true -o ./ising ./src/helpers.cu ./src/kernel.cu ./src/isingEvolution.cu ./src/main.cu
Open the CMD and cd to the repos' directory. Compile using
make -f MakeFileLinux
and run using
ising.out

When the code is executed, all versions (v0, v1, v2, v3) will be executed, one at a time. v0's result is saved and the result of all other versions will be compared to it. A validation check will be run. The runtime of each version will also be printed.
Example expected result in command line:
Executing for n = 5000, k = 10
v0 Implementation Runtime: 7509.000000ms
v1 Implementation Runtime: 30.209057ms
v1 Validation:
Check success!
v2 Implementation Runtime: 35.126846ms
v2 Validation:
Check success!
v3 Implementation Runtime: 22.246336ms
v3 Validation:
Check success!
