NAME
clog2slog - a CLOG to SLOG logfile converter.

SYNOPSIS
clog2slog [ -d=FrameNum ] [ -f=FrameSize ] file.clog

OPTIONS
-d=FrameNum
specifies the number of frames per directory.
-f=FrameSize
specifies the size of a frame in Kilobytes.

DESCRIPTION
The clog2slog command convert CLOG logfile format to SLOG format.

MPI program with -mpilog compile option generate log file to CLOG format without MPE_LOG_FORMAT environment. jumpshot log file viewer iss able to view SLOG format only.

Due to the limitations of the current implementation of SLOG-API If the default or supplied frame size is too small, it may cause problems in generation of the SLOG file. If one encounters some strange errors in using clog2slog, like complaints about frame has been filled up or the maximin allowable number of frames has been reached, try to set the frame size bigger. e.g. 

clog2slog -f=NewFrameSizeInKiloByte filename.clog
If this does NOT work when your frame size reaches 4MB, try set the maximum number of frames to a bigger number than the guess shown in the error message from the previous run of clog2slog. e.g. 
clog2slog -d=NewFrameNumber filename.clog
The default frame size is 64 KB.
