Modify Makefile
There are Makefiles for ALCF Theta (Intel KNL) and OLCF Summit (IBM POWER9) systems. You should use one of these to modify according to your system.
We provide the challenge datasets over Box. Dimensions (Theta x Rho) and corresponding application memory footprints are given below.
Test Datasest:
- ADS1 (360x256): 512 MB
- ADS2 (750x512): 3.6 GB
- ADS3 (1500x1024): 28 GB
- ADS3 (2400x2048): 180 GB
Challenge Datasets: TBA
Each dataset requires a theta file and a sinogram file. Use the code below to directly download datasets to your cluster.
