$sysinfo on MS Windows
by Marcin Błażejowski
Hi,
I have a machine with 4 phisical cores (Intel Core i5-4460 @3.2 GHz
_without HT_) ran under Windows 7 Pro 64 bit. The 'eval $sysinfo' gives
the following message:
------
? eval $sysinfo
bundle anonymous:
nproc = 4
blascore = Haswell
hostname = KATEDRAWSB
os = windows
mpi = 1
blas = openblas
omp_num_threads = 4
ncores = 1
omp = 1
blas_parallel = OpenMP
mpimax = 4
wordlen = 64
------
Shouldn't the 'ncores' entry be set to 4 instead of 1?

Debugging MPI on Windows
by Marcin Błażejowski
Hi,
I face the problem with MPI in Windows: when I start processing on more
than 3 nodes I'm getting the following message (current git 64 bit
compilation + currenty MS MPI 10 library):
##################
MPI nodes: 4, OMP threads: 1
gretlmpi 2019d-git
job aborted:
[ranks] message
[0-1] terminated
[2] application aborted
aborting MPI_COMM_WORLD (comm=0x44000000), error 1, comm rank 2
[3] terminated
---- error analysis -----
[2] on KATEDRAWSB
C:\Program Files\gretl\gretlmpi aborted the job. abort code 1
---- error analysis -----
##################
The same code runs on Linux + OpenMPI even in 20 nodes (haavelmo). So
I'd like to ask how to debug MPI on Windows efficiently?

invalid compressed data
by Artur Tarassow
Dear all,
I am currently working with a 2.8GB csv data file which I stored as a
gdtb file (compressed to about 170MB). However, trying to open the gdtb
file yields an error (see attached screenshot) with the message that the
data is not compressed in a valid manner. Smaller gdtb files work fine
though.
If I remember correctly, I also obtained a message refering to some 4GB
limit this afternoon -- however I cannot replicate this.
The issue occurs on Ubuntu 18.04 using latest git.
Best,
Artur

Datatype of Int or Float in gretl
by Artur Tarassow
Dear all,
I tried to find out what's the default datatype gretl stores integers or
float values. However, I could not find any information on this.
Also, is it somehow possible to define the datatype of a series in
gretl? I would like to restrict the datatype of series S to int8 or so
in order to safe memory space.
Thanks,
Artur

String-valued series encoding
by Riccardo (Jack) Lucchetti
Hi all,
I've had a recurring problem with string-valued series, and I'm struggling
to find a solution.
Suppose you have two or more string-valued series that you get from a csv
or Stata file, and that they represent comparable variables, so they
contain the same strings. Currently, we encode string-valued series by
creating string arrays that get filled by occurrence; this, however,
impleis that there is no guarantee that the correspondence between
internal numerical values and strings is the same for the different
series. This makes it awkward to read the output from commands such as
freq or xtab.
Writing a script to correct for that has proven quite difficult, and what
I was able to come up with is VERY far from elegant. An example script
follows, and suggestions are much appreciated.
<hansl>
set verbose off
function series string_reorder(strings new, series x)
strings ss = strvals(x)
n = nelem(ss)
m = nelem(new)
series tmp = NA
loop i = 1 .. n --quiet
si = ss[i]
k = 0
loop j = 1 .. m --quiet
if si == new[j]
k = j
break
endif
endloop
if k>0 # found
tmp = (x == si) ? k : tmp
endif
endloop
return tmp
end function
clear
set verbose off
outfile "@dotdir/tmp.csv"
printf "var1,var2,var3\n"
printf "a,b,c\na,c,b\nb,b,b\nc,a,b\na,b,c\na,c,c"
end outfile
open "@dotdir/tmp.csv" --quiet
print var1 var2 --byobs
xtab var1 var2 # no good
# record encoding for var1
ss = strvals(var1)
# note: you can't just assign to var2
var2new = string_reorder(ss, var2)
stringify(var2new, ss)
delete var2
rename var2new var2
# values are the same, but the encoding is reordered
print var1 var2 --byobs
xtab var1 var2 # better
</hansl>

'omit const' doesn't work
by Sven Schreiber
Hi,
consider this:
<hansl>
nulldata 10
series x = normal()
ols x const
stat = $coeff(const) / $stderr(const)
printf "Signif. of const: %g\n", 2* pvalue(t, $T-1, abs(stat))
omit const # error
</hansl>
This should work, no?
thanks
