[Swift-user] Problems getting started with coasters

[Andrey Fedorov]

Hi,

I have a processing step that takes somewhere ~2-5 min. It takes on
input two ~5Mb files, and produces a small text file, which I need to
store. I need to compute large number of such jobs, using different
parameters. It seems to me "coaster" is the best execution provider
for my application.

Trying to start simple, I am running first.swift (echo) example that
comes with Swift using different providers: GT2, GT4, GT2/coaster, and
GT4/coaster. All of this is done on Abe NCSA cluster.

Here's my sites.xml:

<pool handle="Abe-GT4">
  <gridftp url="gsiftp://gridftp-abe.ncsa.teragrid.org:2811/" />
  <execution provider="gt4" jobmanager="PBS"
  url="https://grid-abe.ncsa.teragrid.org:8443/wsrf/services/ManagedJobFactoryService"/>
  <workdirectory>/u/ac/fedorov/scratch-global/scratch</workdirectory>
</pool>

<pool handle="Abe-GT4-coasters">
  <gridftp url="gsiftp://gridftp-abe.ncsa.teragrid.org:2811/" />
  <execution provider="coaster" jobmanager="gt4:gt4:pbs"
  url="https://grid-abe.ncsa.teragrid.org:8443/wsrf/services/ManagedJobFactoryService"/>
  <workdirectory>/u/ac/fedorov/scratch-global/scratch</workdirectory>
</pool>

<pool handle="Abe-GT2">
  <gridftp url="gsiftp://gridftp-abe.ncsa.teragrid.org:2811/" />
  <execution provider="gt2" jobmanager="PBS"
  url="grid-abe.ncsa.teragrid.org:2119/jobmanager-pbs"/>
  <workdirectory>/u/ac/fedorov/scratch-global/scratch</workdirectory>
</pool>

<pool handle="Abe-GT2-coasters">
  <gridftp url="gsiftp://gridftp-abe.ncsa.teragrid.org:2811/" />
  <execution provider="coaster" jobmanager="gt2:gt2:pbs"
  url="grid-abe.ncsa.teragrid.org"/>
  <filesystem provider="coaster" url="gt2://grid-abe.ncsa.teragrid.org" />
  <workdirectory>/u/ac/fedorov/scratch-global/scratch</workdirectory>
</pool>

And tc.data is simply

Abe-GT4-coasters echo /bin/echo INSTALLED INTEL32::LINUX null

and I change the site to test different providers.

Now, results:

1) both GT2 and GT4 providers work fine, script completes

2) with GT2+coaster provider, I can see the job in the PBS queue
(requested time is 01:41, I guess this comes with the default coaster
parameters, that I didn't change). The job appears to finish
successfully, but then I get this error:

3) with GT4-coaster provider, I don't get as far as with GT2-coaster.
Possibly I am not setting up properly the site entry. I was not able
to find any examples in the manual how to set coasters with GT4 (can
anyone provide an example?). Here's the error:

Can anybody help figuring this out?

Thanks
