2011July4th

testing saving data. note: the dewar was pumping down, and hadn't been cooled down yet.

I ran RTSchedule and spooler under "xche@mirkwood:/MIRC/" with sudo, the camera setup was rows=16, cols=252, row off=5, col off=2, Nreads=5, Numberoffremes=1000, framesperreset=1000, which is the prism mode. I saved 65 files, and there were 8 files with frame countererror (missing one frame). The ratio was unusually high. (file No.: 0-64)

I changed the setup to rows=48, cols=252, row off=5, col off=2, Nreads=5, Numberoffremes=500, framesperreset=500, which is the grism mode. I saved 70 files, and only one file has frame countererror!! (file No.: 64-134)

changed back to prism mode. I saved 40 files and 6 of them has the frame countererror.

changed back to grism mode. saved 60 files and one of them has the frame countererror.

rebooted mirkwood, and using prism mode, still a lot of frame counter error. It tends to happen continuously, sometimes only received 0 frame out of 1000.

changed to grism mode, no error at all on spooler saving 45 files, but there is error on RTschedule just after saving data finished:

Timeout on blocking semaphore !!! numberCoherent: 10, numberOfCoadds: 15, savenum: 0 ERROR: Starting exposure failed -> 0x544F5554

I doubled the poolsize, but I can't even run the RTschedule.

I reduce the poolsize by half
