And what is fs size and machine config? The machine is an 8 socket, 80 core, 256Gb RAM, HP DL980 server. No special storage being used. Attached is the reaim.config and workfile.dbase files.

# Sample configuration file for the reaim workload # cliff white, OSDL 4/2003 # # This is a comment (duh) # all variables are named in UPPER CASE, unless you want # to write a better option parser. Send me a patch # I'm keeping this, but not used yet # # The disk tests in the AIM-7 test consist of three groups: # basic block I/O tests, the same tests with an added sync, # and the sync I/O tests. Each test determines file size from a # global variable, disk_iteration_count. # # There are two configuration variables that control this, # FILESIZE and POOLSIZE (specified in kilobytes or megabytes). # If POOLSIZE is zero, each child will write or read a total of # FILESIZE bytes. If POOLSIZE is non-zero, child file size is # equal to FILESIZE + (POOLSIZE/number_of_children). Thus when # POOLSIZE is non-zero, I/O per child will be reduced on each # increase in child count. # # For example, specifying a FILESIZE of 10K and a POOLSIZE of # 100K will result in a single child creating a 110K byte file # on each disk device listed. Two children will create a 60K # file, etc. 24 children will create a 14K file, consuming # 328KB per disk device. # # The file and poolsize values can be specified here, or # in the workfile. Values in the workfile will over write # these values FILESIZE 10k POOLSIZE 1m # # A list of disk directories for the exerciser # DISKDIR /tmp/diskdir # To control number of users # STARTUSERS 2 # ENDUSERS 3 # and to control the count # INCREMENT 2 # Number of jobs per child # JOBS 20 # All switch options will use '1' for on, anything else for off # Extra output # VERBOSE 1 # Switch for the crossover # CROSSOVER 1 # Switch for STP-style results file # BRIEF 1 DISKDIR /t0 DISKDIR /t1 DISKDIR /t2 DISKDIR /t3 DISKDIR /t4 DISKDIR /t5 DISKDIR /t6 DISKDIR /t7 DISKDIR /t8 DISKDIR /t9 DISKDIR /t10 DISKDIR /t11 DISKDIR /t12 DISKDIR /t13 DISKDIR /t14 DISKDIR /t15
