Benchmark on Cori Haswell #13

Closed zonca closed 5 years ago

zonca commented 5 years ago

NSIDE 512, all channels, using example_config.cfg just changing channels and NSIDE:

real    2m13.451s
user    73m18.932s
sys     8m34.768s
zonca commented 5 years ago

NSIDE 4096:

therefore 1h 15min each pair of maps (LA, SA) at same frequency, estimate of total time:

7.5 hours

zonca commented 5 years ago

NSIDE 1024:

total about 10m wall-time

zonca commented 5 years ago

total timings for 2 channels, so need to multiply by 6 for production runs
