Here you can find information, how to measure speed of your machine running spinpack.
First you have to download spinpack-2.27.tgz (or better version). Uncompress and untar the file, configure the Makefile, compile the sources and run the executable. Here is an example:
gunzip -c spinpack-2.27.tgz | tar -xf -
cd spinpack
./configure --mpt # configure for pthreads
make speed_test # compile spinpack, create data files
cd exe
# choose problem size (DISK should be fully cached):
# nud=30,10 - MEM=113MB, DISK=840MB, ca.10-45m/run
# nud=28,12 - MEM=735MB, DISK=6GB, ca.3-5h/run (preferred)
nedit daten.i # only for big system
for x in 1 2 4 8 16; do ./spin -t$x; done 2>&1 | tee -a o_speed
Send me the output files together with the characteristic data
of your computer for comparisions. Please also add the output of
grep FLAGS= Makefile and cpu.log if you have.
The next table gives an overview about computation time for a N=40 site system (used for speed test) started at year 2003. First column marks the up- and down-spins (nu,nd) given in daten.i. These numbers define the size of the problem (nn!/(nu!nd!(4nn))) with nu+nd=nn. Other columns list the time needed for writing the matrix (SH) and for the first 40 iterations (i=40) (old version) or the extrapolated time for the first 100 iterations (version 2.27) showed by the output. For the new version ns is the time for filtering symmetric configurations and 12sisj the time for computing the correlations.

Next figure shows the computing time for different older program versions and computers (I update it as soon as I can). The computing time depends nearly linearly from the matrix size n1 (time is proportional to n1^1.07, n1 is named n in the figure).
Memory usage depends from the matrix dimension n1. For the N=40 sample two double vectors and one 5-byte vector is stored in the memory, so we need n1*21 Bytes, where n1 is approximatly (N!/(nu!*nd!))/(4N). Disk usage is mainly the number of nonzero matrix elements hnz times 5 (disk size for tmp_l1.dat is 5*n1 and is not included here). The number of nonzero matrix elements hnz depends from n1 by hnz=11.5(10)*n1^1.064(4), which was found empirically. Here are some examples:

CPU-scaling for spinpack v2.26 (Oct2007)
The T200 has 8 Cores with 4 Threads per Core (CMT). SH is the matrix generation (integer-OPs), i100 are 100 Lanczos-iterations (FLOPs and memory transfers). Created by the gnuplot file speed.gpl.
A typical cpu load for a N=40 site system looks like this:
Data are generated using the following tiny script:
#!/bin/sh
while ps -o pid,pcpu,time,etime,cpu,user,args -p 115877;\
do sleep 30; done | grep -v CPU
115877 is the PID of the process. You have to replace it.
Alternatively you can activate a script activated by daten.i (edit it).
The machine was used by 5 users, therefore peak load is only
about 12CPUs. 735MB memory and 6GB diskspace (or cache) were used.
You can see the initialization process (20min),
the matrix generation (57min) and the first 4 iterations (4x8min).
The matrix generation is most dependend from CPU power.
The iteration time mainly depends from the disk speed
(try: time cat exe/tmp/ht* >/dev/null) and the
speed of random memory access. For example a GS1280-1GHz needs a
bandwith to the disk of 60MB/s per CPU to avoid a bottle neck.
Reading 5GB in 8min means a sequential data rate of 12MB/s which
is no problem for disks or memory cache. Reading randomly a 280MB
vector in 8min means 600kB/s and should also be no problem for the
machine.
You can improve
disk speed using striped disks or files (AdvFS) and putting every
H-block on another disk. The maximum number
of threads was limited to 16, but this can be changed (see src/config.h).
During iterations the multi-processor scaling is so bad on most machines -- why? I guess, this is because of random read access to the vector a (see picture below). I thought a shared memory computer should not have such problems with scaling here, but probably I am wrong. In future I try to solve the problem.
Figure shows dataflow during iterations for 2 CPUs.
Version 2.24 was very slow in calculating the expectation value of <SiSj>. A gprof analysis was showing, that most time was spend for finding the index of an configuration in the configuration table (function b2i of hilbert.c). This was the reason to have a closer look to the speed of memory access. I wrote memspeed.c which was simply read a big number of integers at different steps. Reading integers one after another (sequential read) gives the best results of the order of 1-2GB/s. But worst case where integers are read at distance of about 16kB gives performance of about 10-40MB/s which is a factor of 100 smaller. This is a random access to the RAM. The OpSiSj-function does arround n1*(ln2(n1)+1) such accesses to memory for every SiSj value calculation. I think it should be possible to reduce the randomness of index calculation by using ising energy of each config to divide the configs in blocks. (Sep2006)
