Option hex 01DC of MATMATR (materialize machine attributes) returns the installed processor count for the physical machine. A 10 byte materialization template is needed. The first 4 bytes is a signed binary number that specifies the size of the template (an input value that should be set to 10). At offset 8, the instruction will return the installed processor count in a UBIN(2). Here is a sample C program that uses this option: #include <mih/matmatr.h> #include <stdio.h> static const short attr = _MMTR_PROCESSOR_COUNT; int main( void ) { _MMTR_Template_T template; template.Options.Template_Size = sizeof(_MMTR_Template_T); _MATMATR1( &template, &attr ); printf( "Number of CPUs = %d\n", (int)template.Options.Data.InstProcCount.numProcessors ); return 0; } Bob Donovan/Rochester/IBM, Rochester, MN (507) 253-4036 rjd@us.ibm.com jamesl@hb.quik.com@midrange.com on 10/12/2000 04:48:38 PM Please respond to MI400@midrange.com Sent by: owner-mi400@midrange.com To: MI400@midrange.com cc: jamesl@hb.quik.com Subject: MATMATR 01DC Fellow Programmers: I'm looking for a way to get the number of CPUs on a system (to close a big loophole in our customer license checking routines), and I've been directed to the MATMATR instruction (which I haven't yet had to use in over six years of MI programming!), function 01DC (which naturally isn't documented in my V2R3 MI manual!). Could somebody please give me a hand with this function? It could be a while before I can convince the boss to spring for a more current MI manual. -- James H. H.
