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