hi, It seems that the speed of cp2k becomes a little lowly (about 5%) instead of speeding up after Jan. 10 for the new 'integrate and collocate routines'. Is this general? Do I need set new parameter for the 'distributed realspace grids' part compared with the old one? I test on the XT4 with PGI 7 using 32 water using 32 CPUs. Thanks. Limin
