[SCore-users] the problems about the NAS benchmarks on Omni/scash

[wsg]

Hi,everyone,
I met the following problems on testing NAS benchmarks downloaded from www.pccluster.org:
1. Only CG, EP, FT pass the full test successfully, the result is:
  				1X1		2X1		1X2		4X1		2X2		4X2		
  CG	CLASS=W	19.48	46.77	14.15	56.57	46.51	110.65
  EP	CLASS=W	63.16	32.89	34.16	17.32	17.88	10.50
  FT	CLASS=W	15.72	17.74	9.68	18.37	15.78	21.84
  BT	CLASS=S	8.10	62.67	NAN		79.39	NAN		NAN
  LU	CLASS=W	911.7	859.13*	1408.06	868.64*	DEAD	DEAD
  MG	CLASS=W	19.10	ERR	ERR	ERR	ERR	ERR
  SP	CLASS=S	6.10	861.72	16.90	1232.15	1250.16	DEAD
 
 Note:
 our testbed: 4 nodes(with 2 PIII/700MHz processsors per node), 100M switch Ethernet
 Operating System: RedHat 7.3(kernel-2.4.18)
 compile option: 
	CC		= omcc -omniconfig=scash -t
	CLINK		= omcc -omniconfig=scash -t
	C_LIB		=(none)
	C_INC		= -I../common
	CFLAGS		=(none)
	CLINKFLAGS	= omcc -omniconfig=scash -lm
	RAND		=(none)

 NAN: the result is error because NAN comes out in the result.
 ERR: the program can't run.
 DEAD: the program can't display the result, like dead-lock.
  * : the result display the verification is unsuccessful.

2. MG can pass the 1x1 testing, but under other modes, the fault "VM Fault out of DSM area" comes out.

3. the time in the IS program is error. the run time is always 0.0

4. LU can only pass the 1x1 testing successfully. 

I don't know who meet the above problems. Who can solve them?

Sincerely,
Wu Shaogang
