Performance tests

[jorainer]

Testing the performance of the scripts in converting profile mzML to centroid mzML. This should be done:
A) on my local computer
B) on the cluster
C) on the minicluster

The question is how many processes can we use in parallel before the I/O bottleneck hits.

Results for my local (mac book, quad-core):

• 2 CPUs: 1343 seconds per file.
• 4 CPUs: 1390 seconds per file.

I did run the tests on mccalc07 with the data (both the profile and centroided) on /scratch with 12 files:

CPU	total run time [min]	per file [min]
2	250	40
6	100	45
12	55	50

In addition I tested conversion of 24 files in parallel, which took also about 55 minutes and about 50 minutes per file. So, concluding, we can run 24 files in parallel without major I/O problems (as long as not somebody else is using the cluster with heavy I/O!).
