Using Gotcloud on Flux
Running Gotcloud on Flux
First, Configure GotCloud like you would anywhere else
1. Install GotCloud somewhere as instructed here.
2. Get access to the reference files from someone else, or download them as instructed here.
3. Make a configuration file as usual for your analysis.
4. Include the line BATCH_TYPE = pbs
in that configuration file.
Next, prepare to use the Flux/Torque/PBS cluster
5. Run gotcloud with zero jobs to generate a Makefile.
/path/to/gotcloud/gotcloud snpcall --conf /path/to/configuration.conf --numjobs 0
- The newly generated Makefile will be located in the directory
OUT_DIR
that is specified in your configuration file. It will be namedumake.snpcall.Makefile
.
- The newly generated Makefile will be located in the directory
6. Make a new folder, where you'll run your jobs from.
7. Make an email address to send your jobs' status to. I recommend that you don't use your primary one.
8. Figure out the name of the Flux account that you're going to use. You can see which Flux accounts you have access to by running mdiag -u $USER
and looking at the list after ALIST
.
9. Figure out how many processors you're going to use at once. Run mdiag -a YOU_FLUX_ACCOUNT
. I recommend running MAXPROC
+ MAXIJOB[USER]
many jobs. MAXPROC
is the number of processors on your account, and MAXIJOB[USER]
is the number of jobs that can sit idle in the queue waiting to be run (often 20).
10. Figure out which pipelines to run first. They will run in the order glfN, vcfN, pvcfN, filtN, svmN, splitN, allN where N is the name of a chromosome (ie, 1-22 and maybe X and Y). If you skip a step, the make
will run it for you. If you're confident you can go straight to the step allN. If you want to babysit the jobs, do them one-at-a-time. Your MAKEFILE_TARGETS will need one for each chromosome, like glf1 glf2 glf3 glf4 glf5 glf6 glf7 glf8 glf9 glf10 glf11 glf12 glf13 glf14 glf15 glf16 glf17 glf18 glf19 glf20 glf21 glf22
. Feel free to use the script perl -e 'print "glf$_ " for 1..22'
to mitigate repetitive strain injuries.
11. Inside that new folder, make a new file named pbs.options
that contains the following:
#PBS -l nodes=1:ppn=1,walltime=10:00:00,pmem=4gb,qos=YOUR_FLUX_ACCOUNT_FROM_STEP_8 #PBS -d . #PBS -m abe #PBS -M YOUR_EMAIL_FROM_STEP_7 #PBS -q flux #PBS -l qos=flux #PBS -A YOUR_FLUX_ACCOUNT_FROM_STEP_8 #PBS -V #PBS -j oe
12. Still inside that folder, create a script that you will submit to flux. It should look like this:
#!/bin/sh #PBS -l nodes=1:ppn=4,walltime=150:00:00,pmem=4gb,qos=YOUR_FLUX_ACCOUNT_FROM_STEP_8 #PBS -d . #PBS -m abe #PBS -M YOUR_EMAIL_FROM_STEP_7 #PBS -q flux #PBS -l qos=flux #PBS -A YOUR_FLUX_ACCOUNT_FROM_STEP_8 #PBS -V #PBS -j oe #PBS -N SOME_ARBITRARY_NAME_FOR_THIS_JOB make -w --warn-undefined-variables -k -f /path/to/that/Makefile/umake.snpcall.Makefile -j NUMBER_OF_JOBS_FROM_STEP_9 YOUR_MAKEFILE_TARGETS_FROM_STEP_10 > /path/to/wherever/standard_output 2> /path/to/wherever/standard_error echo "job ended with status $? at $(date)"
