Dear Hugo,
I tried your memory test program (without further modifications) just
after the gc() command:
print(gc())
print(gcinfo(TRUE))
system("/mypath/memorytest.out")
and the result that I got was:
Number of simulations read from ' Particles.txt ' : 9000
-------------------------------------------------------------------
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 480114 12.9 1816453 48.6 5543382 148.1
Vcells 5256970 40.2 119171871 909.3 322607910 2461.4
[1] TRUE
Trying to allocate 1000000000 bytes ... success. Now trying to commit
memory ... succeeded.
Garbage collection 2667 = 2286+194+187 (level 2) ...
12.9 Mbytes of cons cells used (26%)
278.4 Mbytes of vectors used (29%)
Error: cannot allocate vector of size 476.2 Mb
What do you understand of this result ?
Thanks in advance,
Mauricio
