I am using fastGWA-GLMM to analyze patients from the UKBiobank (7971764 markers). I am using a computer with a memory of 128Gb and a 8 CPU. I am having some problemes in computing the GRM. I am using the --make-grm-part option with 20 parts (48962 the first part) and a sparse cutoff of 0.05 The running time is so long (15100 minutes just for 1 part out of 20). Is there some way to accelerate the process?
