I'm compiling on the headnode of my cluster.
The compiler is
ifort -V
Intel(R) Fortran Intel(R) 64 Compiler Professional for applications
running on Intel(R) 64, Version 11.0 Build 20081105 Package ID:
l_cprof_p_11.0.074
which I just downloaded this week.
My cluster top (ganglia) command shows the command running is
fortcom its running .99.88% cpu and using 0.11% memory
command line top
14267 hazards 25 0 60996 16m 7020 R *100 0.1 * 32:29.83 fortcom
So, I do not think I am into swap space. This is the hardware
description from the invoice:
Quad Core Xeon Processor E53452x4MB Cache, 2.33GHz, 1333MHz FSB, PE2950
(222-7341)
Processor: Quad Core Xeon 2nd Processor E5345, 2x4MB Cache, 2.33GHz
1333MHz FSB,
PE2950
Memory: 16GB 667MHz (8x2GB), Dual Ranked DIMMs
cat /etc/redhat-release shows
Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
I compiled pmemd just fine with a 10 something version of ifort.
