* Pseudo-code for RIPEMD-160
|
||||
*
|
||||
* RIPEMD-160 is an iterative hash function that operates on 32-bit words.
|
||||
* The round function takes as input a 5-word chaining variable and a 16-word
|
||||
* message block and maps this to a new chaining variable. All operations are
|
||||
* defined on 32-bit words. Padding is identical to that of MD4.

/* The structure containing information on random-data sources. Each
|
||||
* record contains the source and a relative estimate of its usefulness
|
||||
* (weighting) which is used to scale the number of kB of output from the
|
||||
* source (total = data_bytes / usefulness). Usually the weighting is in the
|
||||
* range 1-3 (or 0 for especially useless sources), resulting in a usefulness
|
||||
* rating of 1...3 for each kB of source output (or 0 for the useless
|
||||
* sources).
|
||||
*
|
||||
* If the source is constantly changing (certain types of network statistics
|
||||
* have this characteristic) but the amount of output is small, the weighting
|
||||
* is given as a negative value to indicate that the output should be treated
|
||||
* as if a minimum of 1K of output had been obtained. If the source produces
|
||||
* a lot of output then the scale factor is fractional, resulting in a
|
||||
* usefulness rating of < 1 for each kB of source output.
|
||||
*
|
||||
* In order to provide enough randomness to satisfy the requirements for a
|
||||
* slow poll, we need to accumulate at least 20 points of usefulness (a
|
||||
* typical system should get about 30 points).
|
||||
*
|
||||
* Some potential options are missed out because of special considerations.
|
||||
* pstat -i and pstat -f can produce amazing amounts of output (the record
|
||||
* is 600K on an Oracle server) which floods the buffer and doesn't yield
|
||||
* anything useful (apart from perhaps increasing the entropy of the vmstat
|
||||
* output a bit), so we don't bother with this. pstat in general produces
|
||||
* quite a bit of output, but it doesn't change much over time, so it gets
|
||||
* very low weightings. netstat -s produces constantly-changing output but
|
||||
* also produces quite a bit of it, so it only gets a weighting of 2 rather
|
||||
* than 3. The same holds for netstat -in, which gets 1 rather than 2.
|
||||
*
|
||||
* Some binaries are stored in different locations on different systems so
|
||||
* alternative paths are given for them. The code sorts out which one to
|
||||
* run by itself, once it finds an exectable somewhere it moves on to the
|
||||
* next source. The sources are arranged roughly in their order of
|
||||
* usefulness, occasionally sources which provide a tiny amount of
|
||||
* relatively useless data are placed ahead of ones which provide a large
|
||||
* amount of possibly useful data because another 100 bytes can't hurt, and
|
||||
* it means the buffer won't be swamped by one or two high-output sources.
|
||||
* All the high-output sources are clustered towards the end of the list
|
||||
* for this reason. Some binaries are checked for in a certain order, for
|
||||
* example under Slowaris /usr/ucb/ps understands aux as an arg, but the
|
||||
* others don't. Some systems have conditional defines enabling alternatives
|
||||
* to commands which don't understand the usual options but will provide
|
||||
* enough output (in the form of error messages) to look like they're the
|
||||
* real thing, causing alternative options to be skipped (we can't check the
|
||||
* return either because some commands return peculiar, non-zero status even
|
||||
* when they're working correctly).
|
||||
*
|
||||
* In order to maximise use of the buffer, the code performs a form of run-
|
||||
* length compression on its input where a repeated sequence of bytes is
|
||||
* replaced by the occurrence count mod 256. Some commands output an awful
|
||||
* lot of whitespace, this measure greatly increases the amount of data we
|
||||
* can fit in the buffer.
|
||||
*
|
||||
* When we scale the weighting using the SC() macro, some preprocessors may
|
||||
* give a division by zero warning for the most obvious expression
|
||||
* 'weight ? 1024 / weight : 0' (and gcc 2.7.2.2 dies with a division by zero
|
||||
* trap), so we define a value SC_0 which evaluates to zero when fed to
|

RELEVANT OPTIMIZATION ISSUES
|
||||
|
||||
EV4
|
||||
|
||||
1. This chip has very limited store bandwidth. The on-chip L1 cache is
|
||||
write-through, and a cache line is transfered from the store buffer to the
|
||||
off-chip L2 in as much 15 cycles on most systems. This delay hurts
|
||||
mpn_add_n, mpn_sub_n, mpn_lshift, and mpn_rshift.
|
||||
|
||||
2. Pairing is possible between memory instructions and integer arithmetic
|
||||
instructions.
|
||||
|
||||
3. mulq and umulh is documented to have a latency of 23 cycles, but 2 of
|
||||
these cycles are pipelined. Thus, multiply instructions can be issued at a
|
||||
rate of one each 21nd cycle.
|
||||
|
||||
EV5
|
||||
|
||||
1. The memory bandwidth of this chip seems excellent, both for loads and
|
||||
stores. Even when the working set is larger than the on-chip L1 and L2
|
||||
caches, the perfromance remain almost unaffected.
|
||||
|
||||
2. mulq has a measured latency of 13 cycles and an issue rate of 1 each 8th
|
||||
cycle. umulh has a measured latency of 15 cycles and an issue rate of 1
|
||||
each 10th cycle. But the exact timing is somewhat confusing.
|
||||
|
||||
3. mpn_add_n. With 4-fold unrolling, we need 37 instructions, whereof 12
|
||||
are memory operations. This will take at least
|
||||
ceil(37/2) [dual issue] + 1 [taken branch] = 20 cycles
|
||||
We have 12 memory cycles, plus 4 after-store conflict cycles, or 16 data
|
||||
cache cycles, which should be completely hidden in the 20 issue cycles.
|
||||
The computation is inherently serial, with these dependencies:
|
||||
addq
|
||||
/ \
|
||||
addq cmpult
|
||||
| |
|
||||
cmpult |
|
||||
\ /
|
||||
or
|
||||
I.e., there is a 4 cycle path for each limb, making 16 cycles the absolute
|
||||
minimum. We could replace the `or' with a cmoveq/cmovne, which would save
|
||||
a cycle on EV5, but that might waste a cycle on EV4. Also, cmov takes 2
|
||||
cycles.
|
||||
addq
|
||||
/ \
|
||||
addq cmpult
|
||||
| \
|
||||
cmpult -> cmovne

This directory contains mpn functions for various HP PA-RISC chips. Code
|
||||
that runs faster on the PA7100 and later implementations, is in the pa7100
|
||||
directory.
|
||||
|
||||
RELEVANT OPTIMIZATION ISSUES
|
||||
|
||||
Load and Store timing
|
||||
|
||||
On the PA7000 no memory instructions can issue the two cycles after a store.
|
||||
For the PA7100, this is reduced to one cycle.
|
||||
|
||||
The PA7100 has a lookup-free cache, so it helps to schedule loads and the
|
||||
dependent instruction really far from each other.
|
||||
|
||||
STATUS
|
||||
|
||||
1. mpn_mul_1 could be improved to 6.5 cycles/limb on the PA7100, using the
|
||||
instructions bwlow (but some sw pipelining is needed to avoid the
|
||||
xmpyu-fstds delay):

2. mpn_addmul_1 could be improved from the current 10 to 7.5 cycles/limb
|
||||
(asymptotically) on the PA7100, using the instructions below. With proper
|
||||
sw pipelining and the unrolling level below, the speed becomes 8
|
||||
cycles/limb.

|

* This runs at 9 cycles/limb on a PA7000. With the used instructions, it can
|

* not become faster due to data cache contention after a store. On the
|
||||
* PA7100 it runs at 7 cycles/limb, and that can not be improved either, since
|
||||
* only the xmpyu does not need the integer pipeline, so the only dual-issue
|
||||
* we will get are addc+xmpyu. Unrolling would not help either CPU.
|
||||
*
|
||||
* We could use fldds to read two limbs at a time from the S1 array, and that
|
||||
* could bring down the times to 8.5 and 6.5 cycles/limb for the PA7000 and
|
||||
* PA7100, respectively. We don't do that since it does not seem worth the
|
||||
* (alignment) troubles...
|
||||
*
|
||||
* At least the PA7100 is rumored to be able to deal with cache-misses
|
||||
* without stalling instruction issue. If this is true, and the cache is
|
||||
* actually also lockup-free, we should use a deeper software pipeline, and
|
||||
* load from S1 very early! (The loads and stores to -12(sp) will surely be

This directory contains mpn functions optimized for Intel Pentium
|
||||
processors.
|
||||
|
||||
RELEVANT OPTIMIZATION ISSUES
|
||||
|
||||
1. Pentium doesn't allocate cache lines on writes, unlike most other modern
|
||||
processors. Since the functions in the mpn class do array writes, we have to
|
||||
handle allocating the destination cache lines by reading a word from it in the
|
||||
loops, to achieve the best performance.
|
||||
|
||||
2. Pairing of memory operations requires that the two issued operations refer
|
||||
to different cache banks. The simplest way to insure this is to read/write
|
||||
two words from the same object. If we make operations on different objects,
|
||||
they might or might not be to the same cache bank.
|
||||
|
||||
STATUS
|
||||
|
||||
1. mpn_lshift and mpn_rshift run at about 6 cycles/limb, but the Pentium
|
||||
documentation indicates that they should take only 43/8 = 5.375 cycles/limb,
|
||||
or 5 cycles/limb asymptotically.
|
||||
|
||||
2. mpn_add_n and mpn_sub_n run at asymptotically 2 cycles/limb. Due to loop
|
||||
overhead and other delays (cache refill?), they run at or near 2.5 cycles/limb.
|
||||
|
||||
3. mpn_mul_1, mpn_addmul_1, mpn_submul_1 all run 1 cycle faster than they
|
||||
should...
