WASP and RT-Linux

Progress reports:

• 15-apr-98 : I've just finished installing all the drivers (GPIB, PIO) and got the software working under regular linux, and of course, a polling PIO device isn't reliable under regular linux. Although the new experimental QNX scheduler works quite well in single observing mode (only using PIO), it is not working well in the calibration routines which need both the GPIB and the PIO to be active at the same time. Really missing is a QNX scheduling API interface on the programming level, so certain threads can be executed at QNX levels. Also tried classical interrupt drivers, but they also don't work well enough in real-time. So, we really have to use RT Linux.
• 31-oct-98 : Simply installing a RT interrupt driver (as opposed to a normal interrupt driven kernel module) worked very much as advertised. Although the lag-readouts are assembled in real-time mode, and passed back to the user via a FIFO, simple polling I/O that is also needed and handled through separate FIFO's appear to have some latencies and/or cause some syncronization problems on the connected WASP machine.
• 15-dec-98 Our 1998 ADASS poster presentation.
• 23-dec-98 : The system as a whole appears to work fine, although some fine-tuning remains to be done. Observing at CSO Jan 16-26 (1999) was quite successfull.
• mar-99: Andy Harris and Christian Holler took WASP up to Mt Wilson, and got some interesting results with Townes' far-infrared receivers. WASP will run in ISI mode for these experiments.
• 10/20-apr-00 : WASP2 for an observing run at CSO
• fall 2001/spring 2002: new WASP2 software, developed by Rauch, Teuben, Pound and Amarnath. Here is the doxygen generated source code documentation.
