Hello everyone!

Using CADO-NFS 2.1.1 linear algebra without MPI with the command:

./bwc.pl :complete thr=8 mn=64 nullspace=left interval=100
matrix=/tmp/matrices/100.bin wdir=/tmp/wdir_8_2.1.1/100 interleaving=0
shuffled_product=1

the lingen phase use only one CPU. It seems as if lingen was sequential.

Why?

Thanking you in advance.
Regards,

Pierpaolo Santucci
