Fitz, Skylar

Speakup kernel built

• Skylar can test software modules, but has no hardware. Does Shodor have anything available?

Combining 32/64-bit kernels

• different trees for the arch-dependent stuff (pre-built modules, etc.)
• For ease, probably stick with 32-bit builds for applications unless there's a dire need for 64

Brings up the question, which apps would need 64?

• Gromacs? mpiblast? Do people even use these on the BCCD? We'd gain a lot of space by removing them
  • (Gromacs, for example, is 120MB compressed, 345M uncompressed)
• Do the MPI implementations, when compiled as 64-bit, have 32-bit compatibility support?
  • after all, mpicc, etc., are just shell scripts (for the most part).

Fitz's torque issues

• pbs_mom and pbs_server don't communicate when head node as 192.168.3.1 (default)
• no amount of fussing around seems to change this fact.
• Try forcing it over loopback?
• Does this happen outside the BCCD too?
• tcpdump and check for differences between 3.1 and a working IP?

C3 support pretty much done (merging in today)

Conferences for the BCCD?
