CREATE CLIC FILE(1) Clic FS User's Manual CREATE CLIC FILE(1)NAME
mkclicfs - Create Clic File
SYNOPSIS
mkclicfs [-d] [-p pagesize] [-b blocksize] [-c compression] [-l logfile] [-n cores] infile outfile
DESCRIPTION
The infile is a loop image (so far only tested with ext3) that is assumed to use pages of pagesize. The outfile is the Compressed Loop
Image Container (Clic), it will contain X parts with blocksize. mkclicfs automatically discards duplicated pages, unless -d is given.
The default for the pagesize is 4096, the default for ext3
The blocksize defines how many pages are grouped together before compression. The default is 32, it is a good balance between overhead and
compression ratio.
The compression preset defines on how slow it is or how good it compresses. Compare with xz presets. -c 0 is fast and -c 9 is (very) slow -
but the compression rate varies a lot - of course depending on the data. Preset 6 is the default.
The logfile is the logfile that is generated from clicfs -l, clicfs will output the access pattern and mkclicfs will reorder the blocks so
they are in order.
The number of cores is by default taken from the system. Sometimes it's wise to not all of them though.

LZMA(1) General Commands Manual LZMA(1)NAME
LZMA - a compression algorithm, based on Lempel Ziv's compression method.
SYNOPSIS
lzma <e|d> inputFile outputFile [switches...]
DESCRIPTION
LZMA provides high compression ratio and very fast decompression, so it is very suitable for embedded applications. For example, it can be
used for ROM (firmware) compression.
lzma is the default and general compression method of 7z format in 7-Zip program.
FUNCTION LETTERS
e Encode file
d Decode file
b Benchmark
SWITCHES
-a{N} Set compression mode - [0, 1], default: 1 (max)
-d{N} Set dictionary - [0,30], default: 23 (8MB)
-fb{N} Set number of fast bytes - [5, 273], default: 128
-mc{N} Set number of cycles for match finder
-lc{N} Set number of literal context bits - [0, 8], default: 3
-lp{N} Set number of literal pos bits - [0, 4], default: 0
-pb{N} Set number of pos bits - [0, 4], default: 2
-mf{MF_ID}
Set Match Finder: [bt2, bt3, bt4, hc4], default: bt4

Hi,
I have 48 cores in my server. I want to assign 50% of the cores to certain programs and rest to some other programms. I found the command "taskset" very good option to assign cpu afinity to already running programms or newly created programms.
