Thanks Edo,
I have tested compiling on different computer ( memory is very large)
CPUINFO:
vendor_id : AuthenticAMD
cpu family : 21
model : 1
model name : AMD Opteron(tm) Processor 6282 SE
stepping : 2
cpu MHz : 2599.926
cache size : 2048 KB
build file : same as above
same input file
timings with semidirect option
1proc - 186 sec
2proc - 103 sec
4proc - 53 sec
6proc - 39 sec
8proc - 31 sec
12proc - 27 sec
16proc - 22 sec
20proc - 20 sec
24proc - 19 sec
32proc - 18 sec
After 16 proc, there seems to no significant scaling..
Is there any wrong thing happen while compilation??
In my build file, I have path for BLAS, SCALPACK. when i checked src/tools/build/config.log, its using internal LAPACK.. Is this correct?
Thanks in advance
Karteek
