I'm running the latest git repository version of CADO-NFS on a c147 and
was wondering why I never had enough relations. As I'm a complete newby
I may genuinely not have enough, but I also have lines like this in
purge.log

pcl@maat ~/cado-nfs/test $ cat tmp/c147.purge.log
/home/pcl/cado-nfs-1.1/build/maat/filter/purge.ra55366a
-poly ./tmp//c147.poly -keep 160 -nrels 38129246
-out ./tmp//c147.purged.gz -npthr 2x2 -basepath ./tmp/
-subdirlist ./tmp//c147.subdirlist -filelist ./tmp//c147.filelist
Warning: unused command-line parameter npthr
Usage: purge [options] -poly polyfile -out purgedfile -nrels nnn
[-basepath <path>] [-subdirlist <sl>] [-filelist <fl>] file1 ... filen
Options:
-excess nnn - initial excess (default 1.01)
-keep nnn - prune if excess > nnn (default 160)
-minpa nnn - purge alg. primes >= nnn (default alim)
-minpr nnn - purge rat. primes >= nnn (default rlim)
-nprimes nnn - expected number of prime ideals
-sos sosfile - to keep track of the renumbering
-raw - output relations in CADO format


Should I be worried?

Should I let the run continue or should I interrupt it and try to
recover somehow?

Right now there are "Info:Running total: 47706267 relations." which is
plausibly large enough to complete the factorization.

The factorization was started with

../cadofactor.pl params=../params/params.c147 wdir=./tmp/ name=c147 n=`cat
num.n`

and, of course, num.n contains a single line containing 147 decimal digits

Thanks,
Paul
