Hi Leif,
Yes, it should be possible to run everything on a single
fast computer with plenty of memory. I have not yet
established that the necessary CPU-sharing during
time-critical parts of each program is handled adequately
for this to work without glitches. Neither Linrad nor
Windows is a very good real-time O/S, and one must work
around their limitations in this area.
I do not think there would be any problems:-)
OK, I tried it with both programs running on the same
(Linux) computer. In this case the two programs were "plrs"
(my "pseudo-Linrad send" program) and MAP65. The Linux
computer has two Xeon CPUs at 2.4 GHz, each with 512 kB L2
cache, and 1 GB memory.
The combination works OK, and but a significant number of
packets (around 400 in each minute, or slightly more than 1%
of the data) are dropped during MAP65's most
compute-intensive parts of each minute. Since plrs does no
significant computing, I imagine that the problem may be
worse when running Linrad + MAP65.
Of course it should be possible to improve this situation; I
have not yet tried to address it. In the meantime, I shall
continue to test with Linrad (or plrs) running on one
computer, MAP65 on another.
