IO Simulator for the BlueTides Project using the bigfile library
After cloning, run bootstrap.sh to get the submodule content.
Run on COMA:
mpirun -n 64 ./iosim -N 4000 -n 64 -s 800000 -w 3 -p ./ -m create -d Test
++++++++++ mpirun ++++++++++
-n ... number of ranks
++++++++++ iosim +++++++++++
'Test' ... filename
-d ... flag to delete files after complete run
-m ... mode: <create/update/read> of files
-q ... path: to access or write files in other folders
-w ... width: defines if items are dim 1 or dim 3
-s ... Nitems: sum of items of dim
-> total number of bytes written in files: Nitems x width x 4bytes
-n ... Nwriters: number of writers (should be <= number of ranks)
-N ... Nfiles: number of files (items are equally subdivided into files)
