A more specific problem that may be encountered on a multi-user or
multi-processor system is running out of memory when a BRLMM run
is initiated and another large-memory BRLMM run is initiated soon
afterwards. In this scenario, the first initiated BRLMM run sees
substantial free memory and chooses a large
--block-size
, but the second
BRLMM run grabs more of the memory. Subsequently, the first run of
BRLMM runs out of memory. This problem can be addressed by
planning the work load on your machine and/or using an appropriately
small block size with the
--block-size
option.
GUIDELINES FOR RAM USAGE WITH BRLMM
Below are some guidelines about how many probesets to run at once
(i.e. the --block-size) in 1.9 gigabytes of RAM as a function of number
of CEL files:
• 50 CEL files
140,000 probesets (i.e. half the dataset for a
mapping 250K chip plus some for prior)
• 100 CEL files
70,000 probesets
• 150 CEL files
47,000 probesets
• 200 CEL files
35,000 probesets
Note that the above recommendations do not use all of the 1.9
gigabytes of RAM. In addition to needing a relatively large amount of
memory, the program also needs relatively large blocks of contiguous
memory and as RAM usage approaches the maximum available, these
become more difficult to find. If you have memory to spare, the
amount of RAM to run all the data at once as a function of Chips is the
following:
• 50 CEL files
1.9 GB
• 100 CEL files
3.3 GB
• 150 CEL files
4.6 GB
• 200 CEL files
6.0 GB
• 250 CEL files
7.3 GB
• 300 CEL files
8.7 GB
