Procedure for gpuowl PRP benchmarks

[selroc]

This is the bash script I use for benchmarking GPUs:

#!/bin/bash

set -o xtrace

# For each gpu model run this script changing the first argument to reflect hardware name.
# Keep gpuowl.log
# For amdgpu-pro a change is required: -use NOASM
cd gpuowl-bench

# First GIMPS discovered prime
./gpuowl -prp 1398269 -iters 100000 -log 5000 -cpu $1 -results bench-1398269-$1.txt
# Last known prime
./gpuowl -prp 82589933 -iters 100000 -log 5000 -cpu $1 -results bench-82589933-$1.txt
# Largest SEL computed exponent
./gpuowl -prp 332252533 -iters 100000 -log 5000 -cpu $1 -results bench-332252533-$1.txt

It supposes that you have created a "gpuowl-bench" directory containing the gpuowl software, and you should provide the first command-line argument representing the GPU hardware name.

I have worked on the procedure to make it extensive, now everything happens in a loop and the user can specify how many loops to run. There is also a procedure to prepare the benchmarks directory.

Explanation of the procedure: the user clones gpuowl into a default 'gpuowl' directory with the following command:

git clone https://github.com/preda/gpuowl

After the user runs the following procedure to prepare the benchmarks directory:

#!/bin/bash
set -o xtrace

cp -r gpuowl/ gpuowl-bench/

And then run this procedure with two parameters: GPU name, and number of loops:

#!/bin/bash

set -o xtrace

# For each gpu model run this script changing the first argument to reflect hardware name;
# The loop number is the second argument: 10 = 1 million iterations per exponent;

# Keep gpuowl.log
# For amdgpu-pro a change is required: -use NO_ASM
cd gpuowl-bench
