Dear all,
I would like to exploit/ test the band parallelisation
I am running a gamma point calculation with nbands 272
I run 3 tests using 272 nband 1, 544 nband 2, 816 nband 3 respectively
Test1
dtiana@daint104:/scratch/daint/dtiana> grep time afm-1.out
total cpu time spent up to now is 11.8 secs
total cpu time spent up to now is 22.0 secs
total cpu time spent up to now is 28.0 secs
Application 5747240 resources: utime ~8080s, stime ~103s, Rss ~173424, inblocks
~11263176, outblocks ~13955496
Test2
dtiana@daint104:/scratch/daint/dtiana> grep time afm-2.out
total cpu time spent up to now is 15.1 secs
total cpu time spent up to now is 27.3 secs
total cpu time spent up to now is 33.9 secs
Application 5747236 resources: utime ~17984s, stime ~209s, Rss ~175072,
inblocks ~22506882, outblocks ~27724272
Test3
dtiana@daint104:/scratch/daint/dtiana> grep time afm-3.out
total cpu time spent up to now is 20.5 secs
total cpu time spent up to now is 30.4 secs
total cpu time spent up to now is 36.5 secs
Application 5747233 resources: utime ~26335s, stime ~309s, Rss ~176636,
inblocks ~33763645, outblocks ~41493055
I am sure I am doing something stupid but I cannot understand what.
Can anyone give me a tip?
Cheers
Davide
