 1 | # Cache
 2 | 
 3 | ## Memory-Hierarchy Understanding Tools
 4 | 
 5 | These are a few programs that benchmark different access patterns and
 6 | graph the results to understand the cache hierarchy of the computer
 7 | they are run on.
 8 | 
 9 | I first saw the technique used for generating these latency numbers in
10 | exercise 5.2 on page 476 of
11 | [Computer Architecture: A
12 | Quantitative Approach](http://www.amazon.com/gp/product/0123704901)
13 | 
14 | The basic idea is that you write a program to walk a contiguous region
15 | of memory using different strides and time how long accessing the
16 | memory takes. The idea for this exercise comes from the
17 | [Ph.D. dissertation](http://portal.acm.org/citation.cfm?id=170337) of
18 | Rafael Héctor Saavedra‑Barrera, where he describes the following
19 | approach:
20 | 
21 | > Assume that a machine has a cache capable of holding D 4‑byte
22 | > words, a line size of b words, and an associativity
23 | > a. The number of sets in the cache is given by D/ab. We
24 | > also assume that the replacement algorithm is LRU, and that the lowest
25 | > available address bits are used to select the cache set.
26 | > 
27 | > Each of our experiments consists of computing many times a simple
28 | > floating-point function on a subset of elements taken from a
29 | > one-dimensional array of N 4-byte elements. This subset is
30 | > given by the following sequence:
31 | > 
32 | > 1, s+1, 2s+1, ..., N-s+1
33 | > 
34 | > Thus, each experiment is characterized by a particular value of
35 | > N and s. The stride s allows us to change the rate at
36 | > which misses are generated, by controlling the number of consecutive
37 | > accesses to the same cache line, cache set, etc. The magnitude of
38 | > s varies from 1 to N/2 in powers of two.
39 | 
40 | He goes on to note
41 | 
42 | > Depending on the magnitudes of N and s in a particular
43 | > experiment, with respect to the size of the cache (D), the line
44 | > size (b), and the associativity (a), there are four
45 | > possible regimes of operations; each of these is characterized by the
46 | > rate at which misses occur in the cache. A summary of the
47 | > characteristics of the four regimes is given in table 5.1.
48 | 
49 | And table 5.1 helpfully summarizes the regimes.
50 | 
51 | | Size of Array |    Stride    | Frequency of Misses | Time per Iteration |
52 | |---------------|--------------|---------------------|--------------------|
53 | | 1 ≤ N ≤ D     | 1 ≤ s  ≤ N/2 |      no misses      |        T           |
54 | | D < N         | 1 ≤ s ≤ b    | one miss every b/s elements| T |
55 | | D < N         | b ≤ s < N/a  | one miss every element | T + M |
56 | | D < N         | N/a ≤ s ≤ N/2| no misses | T |
57 | 
58 | I thought it would be fun to try it, so I wrote a program to do
59 | that.
60 | 
61 | I ran this program on my machine after rebooting in single-user mode
62 | like Hennessy and Patterson suggest so that virtual addresses track
63 | physical addresses a little closer, and with a little help from
64 | gnuplot, I got images like this:

 1 | Running cache-efi.c with no OS:
 2 | 
 3 | ## SETTING UP THE BUILD ENVIRONMENT ##
 4 | 
 5 | MAC OS X:
 6 | 
 7 | Follow the instructions on [EFI
 8 | Programming](http://www.osxbook.com/book/bonus/chapter4/efiprogramming/)
 9 | found in the Mac OS X Book website.
10 | 
11 | 
12 | ## RUNNING THE CODE ##
13 | 
14 | Download refit from
15 | 
16 | http://refit.sourceforge.net/
17 | 
18 | - Get a USB keychain or similar
19 | - Launch Disk Utility
20 |   * make 2 partitions, one HFS+ (small, say 50MB) and the other
21 |     FAT32. This is because EFI can't write to HFS+ file systems, so we
22 |     need a FAT32 FS to get the results.
23 |   * select "Restore" from rEFIt-0.13.dmg to USB stick's HFS+ FS
24 |   * copy cache.efi to /Volumes/EFI/efi/tools
25 |   * eject the USB stick
26 | - Reboot, hold Opt key
27 | - Boot from rEFIt
28 | - Select "Start EFI Shell"
29 | - Let startup.nsh run
30 | - Find the FAT32 partition, in my case, it was in fs3.
31 | <pre>
32 |     Shell> fs3:
33 |     fs3:\> cache 268435456 2> EFI_OUT
34 |     ...
35 | </pre>
36 | Note that it's *very important* to redirect stderr to a
37 | file. Otherwise, the efi shell might hang (something about not being
38 | able to multiplex)
39 | 
40 | - Reboot again, now you have the output in the FAT32 partition
41 | - Since the resulting file is UTF-16 encoded, you need to convert it
42 |   to UTF-8 so that gnuplot can read it.
43 | <pre>
44 |     $ iconv -f UTF-16 -t UTF-8 EFI_OUT > EFI_OUT_UTF8
45 | </pre>
46 | - Now you can plot it.

/results/NOTES:
--------------------------------------------------------------------------------
 1 | These are my notes for interpreting the results.
 2 | 
 3 | I used two laptops for gathering these results.
 4 | 
 5 | 1) Dirac: (sysctl -r machdep.cpu.brand_string)
 6 | 	Intel(R) Core(TM)2 Duo CPU     T7800  @ 2.60GHz
 7 | 	4MB L2 cache
 8 | 	800MHz Bus Speed
 9 | 
10 | 	According to Lenovo:
11 | 	http://www.lenovo.com/psref/pdf/tecbook.pdf
12 | 
13 | 
14 | 	L1 cache - 64KB per core split between data cache (32KB) and
15 | 	instuction cache (32KB)
16 | 
17 | 	L1 data cache - 2x32KB data cache, integrated
18 | 
19 | 	L1 instruction cache - 2x32KB instruction cache, integrated
20 | 
21 | 	L2 cache - size : 2MB or 4MB, full speed, shared between both
22 | 	cores (Intel Advanced Smart Cache)
23 | 
24 | 	L2 cache - data path : 256-bit data path (32 bytes), 64 byte
25 | 	cache line size, 8-way set associative, integrated, unified
26 | 	(on die)
