MADbench2 is run as

> MADbench2.x   $NO_PIX   $NO_BIN   $NO_GANG   $SBLOCKSIZE   $FBLOCKSIZE   $RMOD   $WMOD

where

NO_PIX
Sets the size of the pseudo-data - all the component matrices have NO_PIX x NO_PIX elements
NO_BIN
Sets the size of the pseudo-dataset - there are NO_BIN component matrices
NO_GANG
Sets the level of gang-parallelism - there are NO_GANG gangs
SBLOCKSIZE
Sets the ScaLAPACK blocksize - all matrices will be block-cycically distributed with side SBLOCKSIZE.
FBLOCKSIZE
Sets the file blocksize - all IO will start at a file-offset that is an integer multiple of FBLOCKSIZE.
RMOD
Sets the degree of simultaneous reading - 1:RMOD processors will read at once.
WMOD
Sets the degree of simultaneous writing - 1:WMOD processors will write at once.
