#Icicle example : Montgomery vector operations(mul, add, sub) for allpossible options: is_a_on_device is_b_on_device is_result_on_device is_in_montgomery_form (is_async isn't checked)

Key-Takeaway

Icicle accelerates multiplication operation * using Karatsuba algorithm

Concise Usage Explanation

Define field to be used, e. g.:

#include "api/bn254.h"

using namespace bn254;
typedef scalar_t T;

Running the example

• cd to your example directory
• compile with ./compile.sh
• run with ./run.sh

What's in the example

1. Define the parameters for the example such as vector size
2. Generate random vectors on-host
3. Copy them on-device
4. Execute element-wise vector multiplication on-device
5. Copy results on-host
