The Octane is a dual machine running "hinv" on this I get: 2 195 MHZ IP30 Processors CPU: MIPS R10000 Processor Chip Revision: 2.7 FPU: MIPS R10010 Floating Point Chip Revision: 0.0 Main memory size: 256 Mbytes Instruction cache size: 32 Kbytes Data cache size: 32 Kbytes Secondary unified instruction/data cache size: 1 Mbyte Integral SCSI controller 0: Version QL1040B (rev. 2), single ended Disk drive: unit 1 on SCSI controller 0 Integral SCSI controller 1: Version QL1040B (rev. 2), single ended Disk drive: unit 4 on SCSI controller 1 IOC3 serial port: tty1 IOC3 serial port: tty2 IOC3 parallel port: plp1 Graphics board: MXI Integral Fast Ethernet: ef0, version 1, pci 2 Iris Audio Processor: version RAD revision 12.0, number 1 I compiled the test examples for PVM and it made an SGI64 directory and binaries - these run fine with my other machines. However I assume that it is only using 1 CPU.... I had a look at the pvmgetarch script for this section: if [ "$ARCH" = SGI64 ]; then nproc="`/usr/sbin/mpadmin -n | wc -w`" if [ $nproc -gt 1 -a "$PVM_SHMEM" = ON ]; then ARCH=SGIMP64; fi fi then I ran "/usr/sbin/mpadmin -n | wc -w" which gave me "2" (ie 2 processors). What I expected.. I set the PVM_SHMEM environment variable on and made an SGIMP64 architecture example but the test problems didn't work properly. I tried the hello/hello_other test program and in the task_output got: [0x1c0001] libpvm [t1c0001]: da_new() Warning: shared buffer full,using malloc for the octane and then it just sits there. I ran top on the machine there is about 174MB free (it has 256MB) Have I done something wrong here??? Is the SHMEM stuff a bit unstable or have I screwed it up???
