376.0. "KAP-Fortran on parallel CPU " by TKTV20::MATUZAKI () Tue Apr 15 1997 04:06

	I have a question about KAP-Fortran & KAP-F90 on parallel CPU 
	machine. 

	Digital UNIX 3.2G ( AlphaServer2100 ) 
	Digital Fortran 90 V4.0 (u1) 
	Digital Fortran V40
	KAP for DEC Fortran & KAP Fortran 90 V3.1 

	It,s different on action for an environment variable. This program 
	is close when receive signal. 
	
	# csh 
	# setenv PARALLEL 1
        # limit 
	cputime         unlimited
	filesize        unlimited
	datasize        131072 kbytes
	stacksize       2048 kbytes
	coredumpsize    unlimited
	memoryuse       119768 kbytes
	descriptors     4096 files
	addressspace    1048576 kbytes

	# limit cputime 10 
	# kf90 -fkapargs='-conc' ctime.f 
	# ./a.out 
	cpu limit 
	#                  			<- OK!! 

	# csh 
	# setenv PARALLEL 2 
	# limit 
	cputime         unlimited
	filesize        unlimited
	datasize        131072 kbytes
	stacksize       2048 kbytes
	coredumpsize    unlimited
	memoryuse       119768 kbytes
	descriptors     4096 files
	addressspace    1048576 kbytes

	# kf90 -fkapargs='-conc' ctime.f
	# ./a.out 
	cpu time 				<- NG !! Not end 

	Other Term.............
	
	# ps a | grep -i a.out
	700 ttyq5    T        0:09.69 ./a.out
  	754 ttyq5    S  +     0:00.02 grep -i a.out
