downloads from distinct IPs, over 40,000 job submissions to the two
web-servers, and over 500
citations from the 2005 Bioinformatics, 2006 Bioinformatics,
and 2008 Systematic Biology papers
- Single
versus double precision arithmetics again:
I played around a bit more with RAxML to figure out the cases where it
is worth to use single precision. I ran the SSE3-vectorized Pthreads
version (16 threads on a Sun x4600) of RAxML on a protein dataset with
321,145 distinct alignment patterns and 232 taxa. The double-precision
runs were done under GAMMA and the single-precision runs under CAT.
This means that the memory footprint was at approx. 40GB for GAMMA
under double precision and only at approx. 5GB for CAT under single
precision. The CAT+single precision run was 3 times faster and also
returned a tree with a slightly better likelihood when scored under
GAMMA.

supervisor at the Technical University of Crete, will be visiting us on
