This may be a naive question; I'm an admitted rookie with
the parallel programming library.
Can one not use malloc() and -lpps in the same program?
This happens under 3.0.4, though 3.0.12 is similar.

In article <7237@cs.utexas.edu> I wondered: >Can one not use malloc() and -lpps in the same program? The problem is that private bss is limited to 64k when using shared memory, so malloc() will fail if used to allocate any substantial amount of private memory. A possible workaround is to increase private bss with the -Z switch to ld(1).
