Per the request to test the latest tarball referenced below, I have
built R on AIX 5.3. There is a memory issue, please see 3) below.
1) Build with --enable-BLAS-shlib option. Builds and
passes "make check".
2) GNU libiconv was installed; R configured *without*
the --without-
iconv option. Builds and passes "make check."
3) Memory issue:
a) Although the server possesses 8GB of RAM and
system("ulimit") returns "unlimited" as its value, R does not
"have enough memory."
b) This code works on R-2.4.0 on WinXP with 2GB of RAM, but
fails on the AIX build. Example code:
> xx <- matrix(rep(1e+10,1e7),nrow=1e4,ncol=1e3)
> tmp.df <- as.data.frame(cbind(xx,xx,xx))
Error: cannot allocate vector of size 228.9 Mb
> gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 233035 6.3 467875 12.5 350000 9.4
Vcells 10104141 77.1 31854441 243.1 30104289 229.7
4) Used gcc-4.1.2; I have not tried the native compiler.
Questions:
1) Are there suggestions on how to diagnose and resolve the memory
issue? I'm still building my tool chain and I am in the midst of
installing gdb.
2) Regarding the build process itself, is there more documentation
or results that I should forward?
Thanks,
-jason
