==== Notes ====
== Dummy Task 1 - Tester ==
A brief description of this task including information about software and datasets (size, runs ...) used.

== FSL Batch Job 1 - Chris ==
a dataset from MIRECC with 10 runs (180 timepoints each), 23 copes ... job includes slice-time correction, motion correction, coregistration and stats within FSL, using a bash script that i (chris) wrote (calls FEAT and uses SED for some replacements).
  * run1 finished in 17minutes(node1) | 16minutes(node2), the entire job took 2hr36m (~15m6s per run)
  * needed to replace the fsl distribution of gnuplot with the standard version supplied with linux
  * data read/wrote from/to the linux cluster, it was never transfered across the network to a storage server

== FSL Batch Job 2 - Chris ==
the completed dataset from "batch job 1", was used for a second level FSL analysis ... 10 runs were combined for a within subject average (for all 23 copes).
  * also using a batch script written by me (chris)

== FSL Batch Job 3 - Chris ==
a dataset from MIRECC with 5 runs (180 timepoints each), 23 copes ... job includes slice-time correction, motion correction, coregistration and stats within FSL, using a bash script that i (chris) wrote (calls FEAT and uses SED for some replacements).
  * node1 had 2 instances of the same job running concurrently, each job finished in 1h20min (~16m each)
  * node2 had 4 instances of the same job running concurrently, each job finished in 1h23min (~16.6m each)
  * data read/wrote from/to the linux cluster, it was never transfered across the network to a storage server

== FSL Batch Job 4 - Chris ==
the completed dataset from "batch job 3", was used for a second level FSL analysis ... 5 runs were combined for a within subject average (for all 23 copes).
  * also using a batch script written by me (chris)
  * node1 had 2 instances of the same job running, all finished in ~36m
  * node2 had 4 instances of the same job running, all finished in ~38m

== Freesurfer Job 1 - Josh ==
Running a modified version of Jim's "runfreesurfer" on a 256x256x166 (1mm^3) T1 dataset.  BIAC Scan ID 31816, series600.  This script will run "recon-all" with all options "autorecon1", "autorecon2" and "autorecon3".
  * Had to edit "runfreesurfer" to add the subject directory to the input arguments of "recon-all" (using the -sd flag).
  * All data was processed locally on the node in /home/bizzell/freesurfer
  * Time for biacnode1:  892m, 43.227s (14h,52m,43s)
  * Time for biacnode2:  940m, 25.618s (15h,40m,26s)

== Freesurfer Job 2 - Josh ==
Running the modified version of "runfreesurfer" described above on two datasets:
  * Dataset #1:  256x256x166 (1mm^3) T1, BIAC scan ID 31812, series600
  * Dataset #2:  256x256x166 (1mm^3) T1, BIAC scan ID 31885, series600
For biacnode1, I am running Freesurfer on both of these datasets in parallel.  For biacnode2, I made one copy of each dataset, and am running Freesurfer on all 4 datasets (31812, 31885, 31812 copy, and 31885 copy) in parallel.  \\ \\ 
Time for biacnode1:
  * One dataset took 1096m, 17.684s  (18h,16m,18s)
  * Other dataset took 1274m, 11.860s (21h,14m,12s)
  * Average time 1185m (19h,45m)
Time for biacnode2 (I incorrectly used the command "time" for this one, so I had to get the processing time from the Freesurfer log files):
  * Dataset1 31812:  Start 4/6/07 12:08:28, End 4/7/07 12:05:46; 23h, 57m; 1437m
  * Dataset2 31812 copy: Start 4/6/07 12:08:28, End 4/7/07 11:48:57; 23h, 40m; 1420m
  * Dataset3 31885: Start 4/6/07 12:08:28, End 4/7/07 8:29:03; 20h, 21m; 1221m
  * Dataset4 31885 copy: Start 4/6/07 12:08:28, End 4/7/07 8:25:28; 20h, 17m; 1217m
  * Average 31812: ~1429m; 23h, 49m 
  * Average 31885: 1219m; 20h, 19m
  * Average all: ~1324m; 22h, 4m

== Matlab Job 1 - Trong-Kha ==
SENSE spiral recon on exam 32904, run #7 (spiral-in, 64x64, 30 slices, 168 time points)
  * 1 process on biacnode1: 39m
  * 1 process on biacnode2: 42m

== Matlab Job 2 - Trong-Kha ==
same as Matlab Job 1
  * 2 concurrent processes on biacnode1: 48m | 48m | average: 48m
  * 4 concurrent processes on biacnode2: 53m | 55m | 54m | 54m | average: 54m
