(sigh...) I'd like to report a bug in 3.2.1. and its workaround. Sorry to say but it was calimed that it should be fixed in the maintenance release but it isn't. We are running a 120GTX OS 3.2.1. The program shown below runs on two processors. The graphics manager fails to start up and the graphics is unusable (No window manager).

The IRIS is fully networked running nfs, 4DDN and TCP/IP thus eventually suffering from this. Therefore, I changed the kernel to read the network on CPU0 as follows: 107c107 < #define NBUF 100 /* # buffers in disk buffer cache */ --- > #define NBUF 400 /* # buffers in disk buffer cache */ 215c215 < #define MAXSC 26 --- > #define MAXSC 30 353c353 < int network_processor = 1; --- > int network_processor = 0; modl [/usr/sysgen/master.d] % ... did an lboot and problem solved. The fortran program is special but I wrote a dummy routine which performs the crashes: real x(100,1000), y(100,1000) seed=123456 do 100 i=1,100 do 101 ii=1,1000 x(ii,i)=rand(seed) 101 continue 100 continue write (6,*)'ran done' do 200 i=1,100 do 201 ii=1,1000 y(ii,i)=sin(x(ii,i))*cos(x(ii,i)) y(ii,i)= * (y(ii,i)**1.003)**(1-(sin(x(ii,i))/1000)) do 202 iii=1,900 y(ii,i)= * y(ii,i)**(1-(sin(x(ii,i))/1000)) 202 continue 201 continue 200 continue stop end pfa concurrentizes the 200 do loop which gives a fully paralelly running program. BTW in order to avoid the kernel you could also debug the routinge as root sending a schedctl call but I hate that. I'd like SGI to implement a suspend utility... My questions are Does the network processor really play a role in the game or does it work by accident? Did someone of you experience the same problem? Why does the graphics pipe start version 1.123 but is configured for microcode 1.14+ ? Could someone of SGI comment on that please, the Swiss SGI does not know whats going on.
