• Continued working on psphotStack. This program takes a long time to run and thus debugging is slow going.
• Found and fixed the cause of the memory corruption problem that we worked on last week. Turned out that the code was using a non-thread safe data structure.
• Found and fixed a race condition that caused a SEGV in the extended source fits.
• Modified psphotStack to enable Detection Efficiency measurements.
• Started an exhaustive analysis of the memory usage in psphotStack. With all of the bug fixes and optimizations introduced over the past several weeks it now completes in reasonable time (1-2 hours) for a skycell near the galactic plane, but it still grows to over 32 GB in virtual memory usage in those fields.
• fixed a postage stamp problem that I inadvertently introduced last week.
• updated the list of preferred data_groups for postage stamp requests. With the switch to the ipp-20120802 tag that code is now deployed.
• found and fixed cause of an assertion failure in the extended source fits.
• 2 days as processing czar.
