<DIV><FONT face=Arial size=2>Dear all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm a freshman. There is a infiniband in our
Computer Center. Unfortunately, the system administrator knowing</FONT></DIV>
<DIV><FONT face=Arial size=2>little about how to use infiniband correctly. But I
want to use it, because my DFT calculation with openmpi run </FONT></DIV>
<DIV><FONT face=Arial size=2>in a very low efficiency without </FONT><FONT
face=Arial size=2>it</FONT></DIV>
<DIV><FONT face=Arial size=2>.</FONT></DIV>
<DIV><FONT face=Arial size=2>I have downloaded the OFED-1.3.1.tgz. then I unpack
it using the command like this, tar -zxvf OFED-1.3.1.tgz.</FONT></DIV>
<DIV><FONT face=Arial size=2>And I found intall.pl under the folder, run it
using ./install.pl.</FONT></DIV>
<DIV><FONT face=Arial size=2>then I choose '2' and then '3'. Then I choose OFA
and then yes for every thing and input a location for it.</FONT></DIV>
<DIV><FONT face=Arial size=2>After all above was done. The the programme said
'gcc-3.3.3 rpm is required to build libibverbs'.</FONT></DIV>
<DIV><FONT face=Arial size=2>I have checked my current gcc. I found my vision is
3.2.3, a liitle older. </FONT></DIV>
<DIV><FONT face=Arial size=2>How could I deal with this problem? Should I
update the gcc to 3.3.3? if so, do you think root permissions is
required?</FONT></DIV>
<DIV><FONT face=Arial size=2>Is there a way to finish all the installation
without root permissions? Do you think intel c++ compiler could
</FONT></DIV>
<DIV><FONT face=Arial size=2>doing the same thing instead of gcc?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>any hints will be deeply appreciated.</FONT></DIV>
